How to make window stay behind other windows ?

kotl_give_me_mana

I'm new in Qt. I have a fairly easy question that i cannot solve myself .

I'm creating 5 windows (desktop, Leftbar, Rightbar, Leftbar, Bottombar, Topbar), i want to desktop window always stay bottom of other 4 window. When i click anywhere on desktop window other windows should continue to stay on top. How can i do this ?

@int main(int argc, char *argv[])
{
QApplication a(argc, argv);

    Desktop desktop;
    desktop.show();

    Leftbar leftbar;
    leftbar.show();

    Rightbar rightbar;
    rightbar.show();

    Topbar topbar;
    topbar.show();

    Bottombar bottombar;
    bottombar.show(); 

    return a.exec(&#41;;

setWindowFlags(Qt::WindowStaysOnTopHint);

Thank you for your answer, but when i use

setWindowFlags(Qt::WindowStaysOnTopHint);

on leftbar, rightbar, topbar and bottombar they stay on top of all windows (like when i open documents folder these windows continue to stay on top).

I want these windows stay top of my "desktop" window, not all windows.

I would put
Qt::WindowStaysOnBottomHint
on the Desktop window and not worry about the others.

Good luck

I already put

Qt::WindowStaysOnBottomHint on the desktop window,

but it's not working. When i click on desktop window, other windows(Leftbar, Rightbar, Leftbar, Bottombar, Topbar) go bottom of desktop window.

For more complex behavior,
You can subclass QWidget and reimplement focusInEvent and/or focusOutEvent to emit your custom signal, then process another Slot in another QWidget.

for example, when focus is received on desktop, put another QWidget above (with raise()) or under it(lower()).
