As title, the reason I set ToolWindowsHaveTitleBars="False" is because my control already has a title bar which contains many complex controls.
And I want to keep the existing title bar part of the the exisitng control, instead of putting it to the title bar of ToolWindow, because I may also want to put my control somewhere without the docking site. So I want to keep the integrity of my control.
After setting the ToolWindowsHaveTitleBars to false, I found these ToolWindow no longer draggable. So Is that a way to (like implementing certain interface) enable the ToolWindow can be dragged by holding mouse in some appointed area?
