10 | How-to build an application using guiframe: |

11 | |
---|
12 | 1- Write a main application script along the lines of dummyapp.py |
---|
13 | 2- Write a config script along the lines of config.py, and name it local_config.py |
---|
14 | 3- Write your plug-ins and place them in a directory called "perspectives". |
---|
15 | - Look at local_perspectives/plotting for an example of a plug-in. |
---|
16 | - A plug-in should define a class called Plugin. See abstract class below. |
