Question about the perspectives mechanism

[yiman919]

Before, when I use QDockWidget, I can use restoreGeometry and restoreState to do reload layout of QMainWindow which saved by saveGeometry and saveState , but this way seem not worked with CDockWidget.

I was wondering if I can find a way to restore the last time's layout of CDockWidget .

The perspectives mechanism looks like a solution, so I tried it, but seemed not work as I expected. I found in the "AutoHide" example and "CentralWidget" example, if I created some perspectives, then I can switch layout by clicking perspective list, and if I exited software, when the next time I open the program, the perspectives list is empty.

Thanks again ❤️

I think I found the solution, in CDockManager, we have loadPerspectives() method to do this task
