"""
|
|
This is a little demo of how to make clickable (and changeable) objects with
|
|
FloatCanvas
|
|
|
|
Also an example of constant size, rather than the usual zooming and panning
|
|
|
|
Developed as an answer to a question on the wxPYhton mailing lilst:
|
|
"get panel id while dragging across several panels'
