reasons that stattext was created, so it could be mouse sensitive on all platforms like normal windows. Also updated stattext.py and buttons.py to handle attribute (font & colour) defaults and inheritance the new way. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@27278 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

|
This module implements various forms of generic buttons, meaning that
|
|
they are not built on native controls but are self-drawn.
|
|
|
|
The GenButton is the base. It acts like a normal button but you
|
|
are able to better control how it looks, bevel width, colours, etc.
|
|
|
|
GenBitmapButton is a button with one or more bitmaps that show
|
|
the various states the button can be in.
|
|
|
|
GenToggleButton stays depressed when clicked, until clicked again.
|
|
|
|
GenBitmapToggleButton the same but with bitmaps.
