How to avoid tab title ellipsizing when increasing tab size

Hello,

I believe in that old version there was a TitleConverter used in the DockingWindow template keyed DockingWindowTabbedMdiDocumentTemplateKey.  If you download our default styles/templates and go to the DockingWindow.xaml file, you'll see where it's pulled in.  The converter was initialized as:

<dockingPrimitives:TitleConverter x:Key="DocumentTitleConverter" Prefix="20" Suffix="15" Patch="..." />

Per that configuration, if the document title is longer than 35 characters, it will insert ellipses.  Unfortunately it looks like the only way to alter that would be to clone and redefine the DockingWindowTabbedMdiDocumentTemplateKey in your Application.Resources, using an updated TitleConverter with larger Prefix and Suffix values.  Or stop using the converter altogether if you don't want ellipses.

That should help you achieve what you want.

Thank you for your prompt support!

I confirmed that by redefining the duplicated `DocingWindow.xaml` in the Application Resource as you suggested, and removing the use of `TitleConverter`, the strings are now displayed in full without ellipsizing.

However, there was one issue.
The color change function for the selected tab no longer works, making it unclear which tab is selected.
I may not fully understand the workings of WPF, but is there a way to circumvent this issue?

Hello,

Make sure you include the ControlTemplate.Triggers section in your cloned template update, since those are what allow the tab to change state appearance when the mouse is over the tab, the tab is selected, etc.  You can see those near the bottom of the default DockingWindowTabbedMdiDocumentTemplateKey template.

Hi

Yes, I am sure to include the triggers.

I found that removing the following styles from the DockingWindow, 

<Setter Property="TabBackground" Value="{DynamicResource {x:Static themes:AssetResourceKeys.TabbedMdiContainerTabItemBackgroundNormalBrushKey}}" />
<Setter Property="TabBorderBrush" Value="{DynamicResource {x:Static themes:AssetResourceKeys.TabbedMdiContainerTabItemBorderNormalBrushKey}}" />
<Setter Property="TabBorderThickness" Value="{DynamicResource {x:Static themes:AssetResourceKeys.TabbedMdiContainerTabItemBorderNormalThicknessKey}}" />

which are set when the trigger condition is that the DockingWindow.State is Document and the Workspace.MdiTypeKey matches TabbedMdiHost, worked well.

Was this intended? It seems that the values set here are overriding those set in the ControlTemplate.Triggers section

Hello,

Ordinarily that shouldn't be necessary since everything works out of the box correctly with the default styles/templates.  Trigger Setters normally override default Setters.  However I wonder if with the redefinition of the template, the normal Setter priority order is altered, and perhaps that's what you ran into.
