Re: [Pythoncard-users] Dynamically change font size of a TextArea

[Lawrence A. <la...@gm...>]

try
font = self.components.TextArea1.GetFont()

instead of
font = self.components.TextArea1.font

also you will need to ensure the slider output values are legitimate font sizes
also should be no need to import wx with SetPointSize method

Cheers,
Lawrie
