MoveWindowWithSolitaryTabs issue

[dcembala]

I have a problem involving moving window with tab. In my app I have one tab that is fixed (FixedHeaderCount=1). User can add/remove aditional tabs. I dont want tabs to be dragable so i set InterTabController = null but doing so causes an issue when user tryies to frag fixed tab whole window is being dragged. This is caused by MoveWindowWithSolitaryTabs being placed on InterTabController. This feature I beliewe is controlled in:
private bool ShouldDragWindow(DragablzItemsControl sourceOfDragItemsControl)
{
return (Items.Count == 1
&& (InterTabController == null || InterTabController.MoveWindowWithSolitaryTabs)
&& !Layout.IsContainedWithinBranch(sourceOfDragItemsControl));
}
I think it might be better to change InterTabController == null || => InterTabController != null && or to move MoveWindowWithSolitaryTabs component so InterTabController wouldnt be necesary to disable window drag. Or maybe there is other way to disable window drag I'm not aware of?
