Problem while Docking/Undocking of the QDockWidget on the default mainwindow "Central

[pastispast]

So basically you want rightdock and bottomdock to be fixed size, and maindock to be expanding?

Hi franz thanks for the reply...Actually I don't want that "rightdock" and "bottomdock" to be fixed size but it can be re-size by the user, but automatic they should not dock when maindock close(As dock feature). But both should have dock effects(like float etc...).
