RE: [Pythoncard-users] fonts - day three

[Kevin A. <al...@se...>]

One other thing that you may be tempted to try, but which won't work is dot
dot set notation. For example:

  self.components.field1.text.size = 12 # can't change the font size

This won't work. You can do a get just fine:

  print self.components.field1.text.size

I don't think there is a workaround for the set + set problem, but one of
the Python wizards may have a solution. If you need to set a font property
for a widget, just get a reference to the font, change the attribute you are
interested in, then change the font for the widget.

Also, because the Font class doesn't actually keep a reference to a real
wxPython wxFont, you can just create a Font class that you want to use for a
group of widgets, then iterate through the widgets to make them all use the
same font characteristics. More on this kind of stuff as the fonts mature.
