Can this window have focus?
Can this window be given focus by keyboard navigation? if not, the only way to give it focus (provided it accepts it at all) is to click it.
Adds a child window. This is called automatically by window creation functions so should not be required by the application programmer.
Mirror coordinates for RTL layout if this window uses it and if the mirroring is not done automatically like Win32.

See GetBorder
Cache the best size so it doesn’t need to be calculated again, (at least until some properties of the window change.)
Returns True if the platform supports setting the transparency for this window. Note that this method will err on the side of caution, so it is possible that this will return False when it is in fact possible to set the transparency.
NOTE: On X-windows systems the X server must have the composite extension loaded, and there must be a composite manager program (such as xcompmgr) running.
Directs all mouse input to this window. Call wx.Window.ReleaseMouse to release the capture.
Note that wxWindows maintains the stack of windows having captured the mouse and when the mouse is released the capture returns to the window which had had captured it previously and it is only really released if there were no previous window. In particular, this means that you must release the mouse as many times as you capture it, unless the window receives the wx.MouseCaptureLostEvent event.
Any application which captures the mouse in the beginning of some operation must handle wx.MouseCaptureLostEvent and cancel this operation when it receives the event. The event handler must not recapture mouse.
See GetCaret and SetCaret
Centers the window. The parameter specifies the direction for centering, and may be wx.HORIZONTAL, wx.VERTICAL or wx.BOTH. It may also include wx.CENTER_ON_SCREEN flag if you want to center the window on the entire screen and not on its parent window. If it is a top-level window and has no parent then it will always be centered relative to the screen.
Center with respect to the the parent window
Center(self, int direction=BOTH)
Centers the window. The parameter specifies the direction for centering, and may be wx.HORIZONTAL, wx.VERTICAL or wx.BOTH. It may also include wx.CENTER_ON_SCREEN flag if you want to center the window on the entire screen and not on its parent window. If it is a top-level window and has no parent then it will always be centered relative to the screen.

Converts to screen coordinates from coordinates relative to this window.
Converts to screen coordinates from coordinates relative to this window.
This function simply generates a EVT_CLOSE event whose handler usually tries to close the window. It doesn’t close the window itself, however. If force is False (the default) then the window’s close handler will be allowed to veto the destruction of the window.

Converts a point or size from dialog units to pixels. Dialog units are used for maintaining a dialog’s proportions even if the font changes. For the x dimension, the dialog units are multiplied by the average character width and then divided by 4. For the y dimension, the dialog units are multiplied by the average character height and then divided by 8.

See GetDropTarget and SetDropTarget
See GetEffectiveMinSize
Enable or disable the window for user input. Note that when a parent window is disabled, all of its children are disabled as well and they are reenabled again when the parent is. Returns true if the window has been enabled or disabled, false if nothing was done, i.e. if the window had already been in the specified state.

Returns the window or control that currently has the keyboard focus, or None.
Find a child of this window by window ID
Find a child of this window by label
Find a child of this window by name
Sizes the window so that it fits around its subwindows. This function won’t do anything if there are no subwindows and will only really work correctly if sizers are used for the subwindows layout. Also, if the window has exactly one subwindow it is better (faster and the result is more precise as Fit adds some margin to account for fuzziness of its calculations) to call window.SetClientSize(child.GetSize()) instead of calling Fit.
Similar to Fit, but sizes the interior (virtual) size of a window. Mainly useful with scrolled windows to reset scrollbars after sizing changes that do not trigger a size event, and/or scrolled windows without an interior sizer. This function similarly won’t do anything if there are no subwindows.
See GetFont and SetFont
See GetForegroundColour and SetForegroundColour
Freezes the window or, in other words, prevents any updates from taking place on screen, the window is not redrawn at all. Thaw must be called to reenable window redrawing. Calls to Freeze/Thaw may be nested, with the actual Thaw being delayed until all the nesting has been undone.
This method is useful for visual appearance optimization (for example, it is a good idea to use it before inserting large amount of text into a wxTextCtrl under wxGTK) but is not implemented on all platforms nor for all controls so it is mostly just a hint to wxWindows and not a mandatory directive.
Gets the accelerator table for this window.
Use GetEffectiveMinSize instead.
Returns the current autoLayout setting
Returns the background colour of the window.
Returns the background style of the window.
| See : | SetBackgroundStyle |
|---|
Use GetEffectiveMinSize instead.
This function returns the best acceptable minimal size for the window, if applicable. For example, for a static text control, it will be the minimal size such that the control label is not truncated. For windows containing subwindows (such as wx.Panel), the size returned by this function will be the same as the size the window would have had after calling Fit.

Get border for the flags of this window
Returns the window which currently captures the mouse or None
Returns the caret associated with the window.
Get the (average) character size for the current font.
Get the (average) character size for the current font.
Returns an object containing a list of the window’s children. The object provides a Python sequence-like interface over the internal list maintained by the window..
Get the default attributes for this class. This is useful if you want to use the same font or colour in your own control as in a standard control – which is a much better idea than hard coding specific colours or fonts which might look completely out of place on the user’s system, especially if it uses themes.
The variant parameter is only relevant under Mac currently and is ignore under other platforms. Under Mac, it will change the size of the returned font. See wx.Window.SetWindowVariant for more about this.
Returns the class name of the C++ class using wxRTTI.
Get the origin of the client area of the window relative to the window’s top left corner (the client area may be shifted because of the borders, scrollbars, other decorations...)
Get the client area position and size as a wx.Rect object.
This gets the size of the window’s ‘client area’ in pixels. The client area is the area which may be drawn on by the programmer, excluding title bar, border, scrollbars, etc.
This gets the size of the window’s ‘client area’ in pixels. The client area is the area which may be drawn on by the programmer, excluding title bar, border, scrollbars, etc.
Returns a pointer to the window’s layout constraints, or None if there are none.
Return the sizer that this window is a member of, if any, otherwise None.
Return the cursor associated with this window.
Get the default attributes for an instance of this class. This is useful if you want to use the same font or colour in your own control as in a standard control – which is a much better idea than hard coding specific colours or fonts which might look completely out of place on the user’s system, especially if it uses themes.
Returns the associated drop target, which may be None.
This function will merge the window’s best size into the window’s minimum size, giving priority to the min size components, and returns the results.
Returns the event handler for this window. By default, the window is its own event handler.
Returns the extra style bits for the window.
Returns the default font used for this window.
Returns the foreground colour of the window. The interpretation of foreground colour is dependent on the window class; it may be the text colour or other colour, or it may not be used at all.
(width, height, descent, externalLeading)
Get the width, height, decent and leading of the text using the current or specified font.
Returns the parent of the parent of this window, or None if there isn’t one.
On wxGTK returns a pointer to the GtkWidget for this window as a long integer. On the other platforms this method returns zero.
Returns the platform-specific handle (as a long integer) of the physical window. On wxMSW this is the win32 window handle, on wxGTK it is the XWindow ID, and on wxMac it is the ControlRef.
Gets the help text to be used as context-sensitive help for this window. Note that the text is actually stored by the current wx.HelpProvider implementation, and not in the window object itself.
Get the help string associated with the given position in this window.
Notice that pt may be invalid if event origin is keyboard or unknown and this method should return the global window help text then
Returns the identifier of the window. Each window has an integer identifier. If the application has not provided one (or the default Id -1 is used) then an unique identifier with a negative value will be generated.
Generic way of getting a label from any window, for identification purposes. The interpretation of this function differs from class to class. For frames and dialogs, the value returned is the title. For buttons or static text controls, it is the button text. This function can be useful for meta-programs such as testing tools or special-needs access programs)which need to identify windows by name.
Get the layout direction (LTR or RTL) for this window. Returns wx.Layout_Default if layout direction is not supported.
Returns the windows name. This name is not guaranteed to be unique; it is up to the programmer to supply an appropriate name in the window constructor or via wx.Window.SetName.
Returns the parent window of this window, or None if there isn’t one.
Get the window’s position. Notice that the position is in client coordinates for child windows and screen coordinates for the top level ones, use GetScreenPosition if you need screen coordinates for all kinds of windows.

Returns true if this window has the current mouse capture.
Test if the given style is set for this window.
Does the window have the scrollbar for this orientation?
Returns True if this window’s background is transparent (as, for example, for wx.StaticText) and should show the parent window’s background.
This method is mostly used internally by the library itself and you normally shouldn’t have to call it. You may, however, have to override it in your custom control classes to ensure that background is painted correctly.
See GetHelpText and SetHelpText
Equivalent to calling Show(False).

See GetId and SetId
This function is (or should be, in case of custom controls) called during window creation to intelligently set up the window visual attributes, that is the font and the foreground and background colours.
By ‘intelligently’ the following is meant: by default, all windows use their own default attributes. However if some of the parent’s attributes are explicitly changed (that is, using SetFont and not SetOwnFont) and if the corresponding attribute hadn’t been explicitly set for this window itself, then this window takes the same value as used by the parent. In addition, if the window overrides ShouldInheritColours to return false, the colours will not be changed no matter what and only the font might.
This rather complicated logic is necessary in order to accommodate the different usage scenarios. The most common one is when all default attributes are used and in this case, nothing should be inherited as in modern GUIs different controls use different fonts (and colours) than their siblings so they can’t inherit the same value from the parent. However it was also deemed desirable to allow to simply change the attributes of all children at once by just changing the font or colour of their common parent, hence in this case we do inherit the parents attributes.
Sends an EVT_INIT_DIALOG event, whose handler usually transfers data to the dialog via validators.
Reset the cached best size value so it will be recalculated the next time it is needed.
Is the window in the process of being deleted?
Returns True if the window contents is double-buffered by the system, i.e. if any drawing done on the window is really done on a temporary backing surface and transferred to the screen all at once later.
Returns true if the window is enabled for input, false otherwise.
Returns true if the given point or rectangle area has been exposed since the last repaint. Call this in an paint event handler to optimize redrawing by only redrawing those areas, which have been exposed.

Returns true if the window is retained, false otherwise. Retained windows are only available on X platforms.
For wx.Objects that use C++ reference counting internally, this method can be used to determine if two objects are referencing the same data object.
Returns true if the window is shown, false if it has been hidden.
Returns True if the window is physically visible on the screen, i.e. it is shown and all its parents up to the toplevel window are shown as well.
Returns true if the given window is a top-level one. Currently all frames and dialogs are always considered to be top-level windows (even if they have a parent window).
See GetLabel and SetLabel
Invokes the constraint-based layout algorithm or the sizer-based algorithm for this window. See SetAutoLayout: when auto layout is on, this function gets called automatically by the default EVT_SIZE handler when the window is resized.
See GetLayoutDirection and SetLayoutDirection

This is just a wrapper for ScrollLines(-1).
Lowers the window to the bottom of the window hierarchy. In current version of wxWidgets this works both for managed and child windows.
Disables all other windows in the application so that the user can only interact with this window. Passing False will reverse this effect.

Moves the window to the given position.
Moves this window in the tab navigation order after the specified sibling window. This means that when the user presses the TAB key on that other window, the focus switches to this window.
The default tab order is the same as creation order. This function and MoveBeforeInTabOrder allow to change it after creating all the windows.
Same as MoveAfterInTabOrder except that it inserts this window just before win instead of putting it right after it.
Moves the window to the given position.

Removes and returns the top-most event handler on the event handler stack. If deleteHandler is True then the wx.EvtHandler object will be destroyed after it is popped, and None will be returned instead.
Pops up the given menu at the specified coordinates, relative to this window, and returns control when the user has dismissed the menu. If a menu item is selected, the corresponding menu event is generated and will be processed as usual. If the default position is given then the current position of the mouse cursor will be used.

set up figure for printing. Using the standard wx Printer Setup Dialog.
Pushes this event handler onto the event handler stack for the window. An event handler is an object that is capable of processing the events sent to a window. (In other words, is able to dispatch the events to a handler function.) By default, the window is its own event handler, but an application may wish to substitute another, for example to allow central implementation of event-handling for a variety of different window classes.
wx.Window.PushEventHandler allows an application to set up a chain of event handlers, where an event not handled by one event handler is handed to the next one in the chain. Use wx.Window.PopEventHandler to remove the event handler. Ownership of the handler is not given to the window, so you should be sure to pop the handler before the window is destroyed and either let PopEventHandler destroy it, or call its Destroy method yourself.
Raises the window to the top of the window hierarchy. In current version of wxWidgets this works both for managed and child windows.
See GetRect and SetRect
Mark the specified rectangle (or the whole window) as “dirty” so it will be repainted. Causes an EVT_PAINT event to be generated and sent to the window.
Redraws the contents of the given rectangle: the area inside it will be repainted. This is the same as Refresh but has a nicer syntax.
Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window will receive a hotkey event. It will receive the event even if the application is in the background and does not have the input focus because the user is working with some other application. To bind an event handler function to this hotkey use EVT_HOTKEY with an id equal to hotkeyId. Returns True if the hotkey was registered successfully.
Releases mouse input captured with wx.Window.CaptureMouse.
Removes a child window. This is called automatically by window deletion functions so should not be required by the application programmer.
Find the given handler in the event handler chain and remove (but not delete) it from the event handler chain, returns True if it was found and False otherwise (this also results in an assert failure so this function should only be called when the handler is supposed to be there.)
Reparents the window, i.e the window will be removed from its current parent window (e.g. a non-standard toolbar in a wxFrame) and then re-inserted into another. Available on Windows and GTK. Returns True if the parent was changed, False otherwise (error or newParent == oldParent)
See GetScreenPosition
See GetScreenRect
Converts from screen to client window coordinates.
Converts from screen to client window coordinates.
If the platform and window class supports it, scrolls the window by the given number of lines down, if lines is positive, or up if lines is negative. Returns True if the window was scrolled, False if it was already on top/bottom and nothing was done.
If the platform and window class supports it, scrolls the window by the given number of pages down, if pages is positive, or up if pages is negative. Returns True if the window was scrolled, False if it was already on top/bottom and nothing was done.
Physically scrolls the pixels in the window and move child windows accordingly. Use this function to optimise your scrolling implementations, to minimise the area that must be redrawn. Note that it is rarely required to call this function from a user program.
Sets the accelerator table for this window.
Determines whether the Layout function will be called automatically when the window is resized. lease note that this only happens for the windows usually used to contain children, namely wx.Panel and wx.TopLevelWindow (and the classes deriving from them).
This method is called implicitly by SetSizer but if you use SetConstraints you should call it manually or otherwise the window layout won’t be correctly updated when its size changes.
Sets the background colour of the window. Returns True if the colour was changed. The background colour is usually painted by the default EVT_ERASE_BACKGROUND event handler function under Windows and automatically under GTK. Using wx.NullColour will reset the window to the default background colour.
Note that setting the background colour may not cause an immediate refresh, so you may wish to call ClearBackground or Refresh after calling this function.
Using this function will disable attempts to use themes for this window, if the system supports them. Use with care since usually the themes represent the appearance chosen by the user to be used for all applications on the system.
Returns the background style of the window. The background style indicates how the background of the window is drawn.
wx.BG_STYLE_SYSTEM The background colour or pattern should be determined by the system wx.BG_STYLE_COLOUR The background should be a solid colour wx.BG_STYLE_CUSTOM The background will be implemented by the application.
On GTK+, use of wx.BG_STYLE_CUSTOM allows the flicker-free drawing of a custom background, such as a tiled bitmap. Currently the style has no effect on other platforms.

Use SetInitialSize
Sets the caret associated with the window.
This sets the size of the window client area in pixels. Using this function to size a window tends to be more device-independent than wx.Window.SetSize, since the application need not worry about what dimensions the border or title bar have when trying to fit the window around panel items, for example.

Sets the window to have the given layout constraints. If an existing layout constraints object is already owned by the window, it will be deleted. Pass None to disassociate and delete the window’s current constraints.
You must call SetAutoLayout to tell a window to use the constraints automatically in its default EVT_SIZE handler; otherwise, you must handle EVT_SIZE yourself and call Layout() explicitly. When setting both a wx.LayoutConstraints and a wx.Sizer, only the sizer will have effect.
This normally does not need to be called by application code. It is called internally when a window is added to a sizer, and is used so the window can remove itself from the sizer when it is destroyed.
Sets the window’s cursor. Notice that the window cursor also sets it for the children of the window implicitly.
The cursor may be wx.NullCursor in which case the window cursor will be reset back to default.
Sets the position and size of the window in pixels. The sizeFlags parameter indicates the interpretation of the other params if they are equal to -1.
wx.SIZE_AUTO A -1 indicates that a class-specific default should be used. wx.SIZE_USE_EXISTING Existing dimensions should be used if -1 values are supplied. wxSIZE_ALLOW_MINUS_ONE Allow dimensions of -1 and less to be interpreted as real dimensions, not default values.
Put the native window into double buffered or composited mode.
Associates a drop target with this window. If the window already has a drop target, it is deleted.
Sets the event handler for this window. An event handler is an object that is capable of processing the events sent to a window. (In other words, is able to dispatch the events to handler function.) By default, the window is its own event handler, but an application may wish to substitute another, for example to allow central implementation of event-handling for a variety of different window classes.
It is usually better to use wx.Window.PushEventHandler since this sets up a chain of event handlers, where an event not handled by one event handler is handed off to the next one in the chain.
Sets the extra style bits for the window. Extra styles are the less often used style bits which can’t be set with the constructor or with SetWindowStyleFlag()
Set’s the focus to this window, allowing it to receive keyboard input.
Set focus to this window as the result of a keyboard action. Normally only called internally.
In contrast to SetFocus (see above) this will set the focus to the panel even of there are child windows in the panel. This is only rarely needed.
Sets the font for this window.
Sets the foreground colour of the window. Returns True is the colour was changed. The interpretation of foreground colour is dependent on the window class; it may be the text colour or other colour, or it may not be used at all.
Sets the help text to be used as context-sensitive help for this window. Note that the text is actually stored by the current wx.HelpProvider implementation, and not in the window object itself.
Associate this help text with all windows with the same id as this one.
Sets the identifier of the window. Each window has an integer identifier. If the application has not provided one, an identifier will be generated. Normally, the identifier should be provided on creation and should not be modified subsequently.
A ‘Smart’ SetSize that will fill in default size components with the window’s best size values. Also set’s the minsize for use with sizers.
Set the text which the window shows in its label if applicable.
Set the layout direction (LTR or RTL) for this window.
A more convenient method than SetSizeHints for setting just the max size.
A more convenient method than SetSizeHints for setting just the min size.
Sets the window’s name. The window name is used for ressource setting in X, it is not the same as the window title/label
Move(self, Point pt, int flags=SIZE_USE_EXISTING)
Moves the window to the given position.
Sets the position and size of the window in pixels using a wx.Rect.
Sets the position of one of the built-in scrollbars.
Sets the scrollbar properties of a built-in scrollbar.
Sets the size of the window in pixels.
Allows specification of minimum and maximum window sizes, and window size increments. If a pair of values is not set (or set to -1), the default values will be used. If this function is called, the user will not be able to size the window outside the given bounds (if it is a top-level window.) Sizers will also inspect the minimum window size and will use that value if set when calculating layout.
The resizing increments are only significant under Motif or Xt.

Sets the size of the window in pixels.
Sets the window to have the given layout sizer. The window will then own the object, and will take care of its deletion. If an existing layout sizer object is already owned by the window, it will be deleted if the deleteOld parameter is true. Note that this function will also call SetAutoLayout implicitly with a True parameter if the sizer is non-None, and False otherwise.
The same as SetSizer, except it also sets the size hints for the window based on the sizer’s minimum size.
Dialogs, notebook pages and the status bar have this flag set to true by default so that the default look and feel is simulated best.
Attach a tooltip to the window.
Attach a tooltip to the window.
Attempt to set the transparency of this window to the alpha value, returns True on success. The alpha value is an integer in the range of 0 to 255, where 0 is fully transparent and 255 is fully opaque.
Deletes the current validator (if any) and sets the window validator, having called wx.Validator.Clone to create a new validator of this type.
Set the the virtual size of a window in pixels. For most windows this is just the client area of the window, but for some like scrolled windows it is more or less independent of the screen window size.
Allows specification of minimum and maximum virtual window sizes. If a pair of values is not set (or set to -1), the default values will be used. If this function is called, the user will not be able to size the virtual area of the window outside the given bounds.

SetWindowStyleFlag(self, long style)
Sets the style of the window. Please note that some styles cannot be changed after the window creation and that Refresh() might need to be called after changing the others for the change to take place immediately.

Sets the variant of the window/font size to use for this window, if the platform supports variants, for example, wxMac.
Return true from here to allow the colours of this window to be changed by InheritAttributes, returning false forbids inheriting them from the parent window.
The base class version returns false, but this method is overridden in wxControl where it returns true.
Shows or hides the window. You may need to call Raise for a top level window if you want to bring it to top, although this is not needed if Show is called immediately after the frame creation. Returns True if the window has been shown or hidden or False if nothing was done because it already was in the requested state.

Reenables window updating after a previous call to Freeze. Calls to Freeze/Thaw may be nested, so Thaw must be called the same number of times that Freeze was before the window will be updated.

Turn the flag on if it had been turned off before and vice versa, returns True if the flag is turned on by this function call.

Transfers values from child controls to data areas specified by their validators. Returns false if a transfer failed. If the window has wx.WS_EX_VALIDATE_RECURSIVELY extra style flag set, the method will also call TransferDataFromWindow() of all child windows.
Transfers values to child controls from data areas specified by their validators. If the window has wx.WS_EX_VALIDATE_RECURSIVELY extra style flag set, the method will also call TransferDataToWindow() of all child windows.
Disconnects the event handler binding for event from self. Returns True if successful.
Unregisters a system wide hotkey.
Calling this method immediately repaints the invalidated area of the window instead of waiting for the EVT_PAINT event to happen, (normally this would usually only happen when the flow of control returns to the event loop.) Notice that this function doesn’t refresh the window and does nothing if the window has been already repainted. Use Refresh first if you want to immediately redraw the window (or some portion of it) unconditionally.

This function sends EVT_UPDATE_UI events to the window. The particular implementation depends on the window; for example a wx.ToolBar will send an update UI event for each toolbar button, and a wx.Frame will send an update UI event for each menubar menu item. You can call this function from your application to ensure that your UI is up-to-date at a particular point in time (as far as your EVT_UPDATE_UI handlers are concerned). This may be necessary if you have called wx.UpdateUIEvent.SetMode or wx.UpdateUIEvent.SetUpdateInterval to limit the overhead that wxWindows incurs by sending update UI events in idle time.
Validates the current values of the child controls using their validators. If the window has wx.WS_EX_VALIDATE_RECURSIVELY extra style flag set, the method will also call Validate() of all child windows. Returns false if any of the validations failed.

Moves the pointer to the given position on the window.
NOTE: This function is not supported under Mac because Apple Human Interface Guidelines forbid moving the mouse cursor programmatically.

Transfer the region of the agg buffer defined by bbox to the display. If bbox is None, the entire buffer is transferred.
Backend derived classes should call this function on any mouse button press. x,y are the canvas coords: 0,0 is lower, left. button and key are as defined in MouseEvent.
This method will be call all functions connected to the ‘button_press_event’ with a MouseEvent instance.
Backend derived classes should call this function on any mouse button release.
This method will be call all functions connected to the ‘button_release_event’ with a MouseEvent instance.
Render the figure using agg.
Draw a cursor in the event.axes if inaxes is not None. Use native GUI drawing for efficiency if possible
This method will be call all functions connected to the ‘draw_event’ with a DrawEvent
Render after a delay if no other render requests have been made.
Backend derived classes should call this function when entering canvas
return the figure width and height in points or pixels (depending on the backend), truncated to integers
Performs update of the displayed image on the GUI canvas, using the supplied device context. If drawDC is None, a ClientDC will be used to redraw the image.
call when GUI is idle
This method will be call all functions connected to the ‘key_press_event’ with a KeyEvent
This method will be call all functions connected to the ‘key_release_event’ with a KeyEvent
Backend derived classes should call this function when leaving canvas
Backend derived classes should call this function on any motion-notify-event.
This method will be call all functions connected to the ‘motion_notify_event’ with a MouseEvent instance.
Connect event with string s to func. The signature of func is:
def func(event)
where event is a matplotlib.backend_bases.Event. The following events are recognized
For the location events (button and key press/release), if the mouse is over the axes, the variable event.inaxes will be set to the Axes the event occurs is over, and additionally, the variables event.xdata and event.ydata will be defined. This is the mouse location in data coords. See KeyEvent and MouseEvent for more info.
Return value is a connection id that can be used with mpl_disconnect().
Example usage:
def on_press(event):
print 'you pressed', event.button, event.xdata, event.ydata
cid = canvas.mpl_connect('button_press_event', on_press)
disconnect callback id cid
Example usage:
cid = canvas.mpl_connect('button_press_event', on_press)
#...later
canvas.mpl_disconnect(cid)
Mouse event processor which highlights the artists under the cursor. Connect this to the ‘motion_notify_event’ using:
canvas.mpl_connect('motion_notify_event',canvas.onHilite)
Mouse event processor which removes the top artist under the cursor. Connect this to the ‘mouse_press_event’ using:
canvas.mpl_connect('mouse_press_event',canvas.onRemove)
This method will be called by artists who are picked and will fire off PickEvent callbacks registered listeners
set the canvas size in pixels
This method will be call all functions connected to the ‘resize_event’ with a ResizeEvent

Setting the resizing
Set the title text of the window containing the figure. Note that this has no effect if there is no window (eg, a PS backend).
Start an event loop. This is used to start a blocking event loop so that interactive functions, such as ginput and waitforbuttonpress, can wait for events. This should not be confused with the main GUI event loop, which is always running and has nothing to do with this.
Call signature:
start_event_loop(self,timeout=0)
This call blocks until a callback function triggers stop_event_loop() or timeout is reached. If timeout is <=0, never timeout.
Raises RuntimeError if event loop is already running.
Start an event loop. This is used to start a blocking event loop so that interactive functions, such as ginput and waitforbuttonpress, can wait for events. This should not be confused with the main GUI event loop, which is always running and has nothing to do with this.
This function provides default event loop functionality based on time.sleep that is meant to be used until event loop functions for each of the GUI backends can be written. As such, it throws a deprecated warning.
Call signature:
start_event_loop_default(self,timeout=0)
This call blocks until a callback function triggers stop_event_loop() or timeout is reached. If timeout is <=0, never timeout.
Stop an event loop. This is used to stop a blocking event loop so that interactive functions, such as ginput and waitforbuttonpress, can wait for events.
Call signature:
