Change the font in the window title bar

Hi Jack,

Right now the Window's template uses the SystemFonts.CaptionFontFamilyKey, CaptionFontSizeKey, and CaptionFontStyleKey.  So you should be able to do something like this as an example of changing font size:

<mscorlib:Double x:Key="{x:Static SystemFonts.CaptionFontSizeKey}">22</mscorlib:Double>

So first, this forum doesnt seem to play well with IE 11.

Having trouble implementing your "something like" suggestion.

Where does this xaml go?

Is it something like that or exactly that?

Not  to be pedantic but could not apply your "answer" as you wrote it up.

Hi Jack,

If you put that XAML line in your Window.Resources (which probably will work for that single Window instance) or Application.Resources (which will apply to all Window instances), then that's all you'll need to do to change the font size.  You are effectively altering the caption font size resource that is used by our themed Window template with that line.

And you'd also need an xmlns at the top like this so that "mscorlib:" is defined:

xmlns:mscorlib="clr-namespace:System;assembly=mscorlib"

Also, what specific issues do you see with IE 11 in the forum?

RE: The IE 11 problem pressing the Un Mark answer doesnt refresh the screen.

YOu souktion works thanks

your answer is very good. And I can set the font size.

Now how do I set font family?

I Tried this,

<Window.Resources>
<mscorlib:Double x:Key="{x:Static SystemFonts.CaptionFontSizeKey}">16</mscorlib:Double>
<FontFamily x:Key="{x:Static SystemFonts.CaptionFontFamily }">Showcard Gothic</FontFamily>
</Window.Resources>

size works, font family doesn't

Got it

SystemFonts.CaptionFontFamilyKey
