I want to alter the focus visual properties at app level.(like the Mail App). As per the Focus Visual Docucmentation, it is possible to change the primary and secondary border color at app level by changing the respective system brush resources.
There are only two color properties for the focus visuals: the primary border color, and the secondary border color. These focus visual border colors can be changed per-control on an page level, and globally on an app-wide level:
To brand focus visuals app-wide, override the system brushes:
<SolidColorBrush x:Key="SystemControlFocusVisualPrimaryBrush" Color="DarkRed"/> <SolidColorBrush x:Key="SystemControlFocusVisualSecondaryBrush" Color="Pink"/>
But no such thing is provided in the doc for the thickness of the focus visual. Is there any resource available or any other way to specify the thickness at app level?
