[solved]How can I cover part of a fullscreen widget and hide a widget ?
I worked on the unbuntu14.02, Qt5.5
Here has two widgets, A and B.
A is a fullScreen widget(now I used A.showFullScreen)
B is another widget, I want it hide on then top of screen at first ,when the mouse move to the top of screen it will show up, and has some button to control A.
I used QLocalServer and QLocalClient as communication tool.It work fine when A and B are both show up.
here is my problem:
1 when A is fullScreen , I move mouse to top of screen, and notify B to show up, but how can B cover A ?, I used show and set Qt::WindowStaysOnTopHint，But it didn't work.
2 I set B move(x, 0 - size().y()) to hide B, but it did't work, it seems it's the problem if ubuntu top bar and left launch bar . I did not use hide() because i want to use a timer to show it slowly disappear and show up.
Thanks for reading and please forgive my pool English, I hope the above text accurately expressed what I mean
Have you tried raise(); for B ?
Also, for widget B. If you create it with parent as A, then move will clip B to A.
So check you give it nothing in B's constructor to be allowed to move it offscreen.
(it that is your issue)
@mrjj Thanks for reply, B.rise() is work.
