How to hide a title bar in CDockablePane in float state?

Question

virtual int GetCaptionHeight() const{ return 0; }

我用它可以将标题栏隐藏在对接状态，但是当它浮动时，标题就存在了。

The caption is drawn from the Pane only when it is not floating. Just look into the default implementation for GetCaptionHeight !

The pane is inside a CPaneFrameWnd when it is floating.

AFAIK you have to control over the outer frame window. It is created by CreateDefaultMiniframe . It should usually create a CPaneFrameWnd .

Derive your own class from the default mini frame class. (should be CPaneFrameWnd , but better recheck it). There is a virtual function CPaneFrameWnd::GetCaptionRect .

Use SetMiniFrameRTC in your CDockablePane class to set this new class frame to be used for your pane.
