how to make QToolButton auto pop-up menu ?

[DBoosalis]

Why not emit a signal inside the enter event say "emit popupMenu(e->globalPos())"
Then in your mainwindow you have a slot like this

MyMainWindow::showToolbarPopupSlot(QPoint &p)
{
myPopupMenu->popup(p);
}

I do this for table views anyway. Hope it is of some help

Maybe I don't get it, but why "QToolButton::setMenu":http://qt-project.org/doc/qt-4.8/qtoolbutton.html#setMenu is not sufficient ?

[DBoosalis]

Because your redefining the behavior to show on "mouseEnter", if you have your menu as defined by QToolButton cannot you just do

@virtual void enterEvent( QEvent * e )
{
if(menu())
menu()->popup(e->pos // or e->globalPos() ?)
}@

Ok I see. Install an event filter on the menu and in the eventFilter of your class if object is the menu and event is QEvent::Leave close the menu

[DBoosalis]

That's a good problem and you idea for the eventFilter sounds sane but does not Menu have a leaveEvent() method, but that means createing your own MyMenuClass from QMenu.

How ever you get it to work, please post back, as in the future I may want such behavior in an application. Maybe others too

QMenu is a QWidget, so it has leave event

bq. Ok I see. Install an event filter on the menu and in the eventFilter of your class if object is the menu and event is QEvent::Leave close the menu

I have thought this method, but it's not viable!
because while I hover on 1st QToolbutton ,then Associated menu pops up. but while I don't move the mouse to enter the menu to select 1 item but I move to the other QToolButton. then 2 menus pop up simultaneously.(more worse is the previous one is not closed normally)

thanks any way.but you may don't get what I have asked.The kay point is not about the pops the menu but how can I control the menu automatic close .

Even I hover more than 1 QToolbuttons consecutively but I don't move the mouse enters the any menus pop up before.

Sorry for delay. Why is not viable ? I used this type of automatically show/hide menu and is viable.

That's why I said to install an event filter on the menu. If mouse leave the menu, hide it.

@jzq740176597 Did you manage to get it working? I'm facing the same problem here...
