Custom widget derived from wxGenButton
I have created a custom widget derived from wxGenButton. I would like to be able to use it in wxGlade.

Alberto Griggio has made several changes to wxGlade to allow this to work.

However there is a problem when I load a .wxg file into wxGlade which contains one of the custom widgets. This is because wxGlade sets the ‘parent’ arg to None when it creates the widget.

This causes a problem in GenButton.init() because the call

font = parent.GetFont() fails.

If I modify init() like this:

    if parent:

        font = parent.GetFont()

    else:

        font = wx.SystemSettings_GetFont(wx.SYS_DEFAULT_GUI_FONT)

then it works OK. Would it be possible to incorporate a change like this in wxPython?

Using wxGlade-0.3.3 from CVS; wxPython-2.5.1.5; Python-2.3.3; Win98SE.

I've already made other changes that elimiated the need for "font = parent.GetFont()" but I wonder how passing parent=None could possibly work. Isn't there an exception raised from wx.PyControl.__init__?
