I use wxPython 2.9.4.0. unicode (windows 7)

I found that wx.EVT_ERASE_BACKGROUND is not fired.

DragImage code in wxPython 2.9 Demo

—> cannot paint background…

How can I paint my custom background.

You probably need to call the window's SetBackgroundStyle method, although sending erase events should be the default. See:

DragImage example code in wxPython 2.9 Demo

—> self.SetBackgroundStyle(wx.BG_STYLE_CUSTOM) ===> this is problem…
