Hi!

I use CXTPDockingPaneManager with UseSplitterTracker(TRUE) and I�ve a problem:

While docking pane resizing or dragging, all applications in the PC look freezing.

You can see this effect in your samples. But it�s unacceptable for my application.

I found you call LockWindowUpdate in CXTPSplitterTracker::Track function for DesktopWindow. Why do you use this lock?

I can�t use UseSplitterTracker(FALSE) , because there is a lot of drawing in my window attached to docking pane, and in this case, the whole window is flickering to much while pane is dragging or resizing.

Could you add in the next ver. a solution of this problem? Perhaps it could be a public method to allow enabling/disabling LockWindowUpdate in CXTPSplitterTracker::Track? Or another solution.

Hi,

If you don't want lock, you have to use UseSplitterTracker(FALSE) and optimize your drawing to not flicker. Use double buffer or something.

Thank you for your answer, Oleg.

But what reason to lock desktop update with splitter tracker? Many programs with docking panels (Visual Studio for example) work without any locks and they all look normal.
