I’ve updated styling code to allow more customization. To change global tabs font family and font size you should now use the following format:
Style resources settings
The result is the same as in the previous post:
Default tabs style
Custom tabs style
More customization means that now you can, for example, set Italic font style only for the selected tab name:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:TabsStudio="clr-namespace:TabsStudio;assembly=TabsStudio">
<Style TargetType="TabsStudio:TabNameLabel">
<Style.Triggers>
<Trigger Property="IsTabSelected" Value="True">
<Setter Property="Control.FontStyle" Value="Italic"/>
</Trigger>
</Style.Triggers>
</Style>
</ResourceDictionary>
The result is:
Custom selected tab name
Notice how the not selected tab name and extensions on the selected tab stay in the normal font style.
