c++ - Qt::Tool appear too fast when parent restored -


i have qt application, window several child widgets qt::tool windows.

when minimize window , restore on windows 7 child widgets appear immediately, parent window not because of animation.

is there way prevent behavior , make child windows appear after main window?

why don't hide tool windows while main window restoring? can use piece of code , adapt needs:

void mainwindow::changeevent( qevent* e ) {   if ( e->type() == qevent::windowstatechange )   {     qwindowstatechangeevent* event =          static_cast< qwindowstatechangeevent* >( e );     if ( event->oldstate() & qt::windowminimized ) {       qdebug() << "the window has been restored!";     }     else if ( (event->oldstate() == qt::windownostate) &&                (this->windowstate() == qt::windowmaximized) ) {       qdebug() << "the window has been maximized!";     }   } }

for example, can start timer amount of time, , have slot connected child tool windows, making them appear wish.

you can play transparency in child tool windows, , emulate main window effects.

as recall, do:

setstylesheet("background:transparent;"); setattribute(qt::wa_translucentbackground); setwindowflags(qt::framelesswindowhint);

hope helped!
