But, if you retrieve the window list using the call CGWindowListCopyWindowInfo , you can observe that the value of kCGWindowLayer is more than 20 (25, 103 etc).

问题 Is it possible, that the FontSize getting smaller if I shrink the window and getting bigger if I enlarge the window? 回答1: Wrap your text inside a Viewbox . <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"> <Viewbox> <TextBlock Text="Sizes to fit!"/> </Viewbox> </Window> 回答2: I've never tried this, but I imagine you can bind the font size property of your text to the window size through a converter method.
