Title in QMenu
Message 1 in thread
Hi.
Is there a simple way to display a title on top of a QMenu?
I would like to create e context menu (that popup on right-click) with a title. I see that QMenu can have a title (I can pass a title in the constructor or call setTitle()), but this string is never displayed.
I also tried to subclass QMenu and add a QAction as title, but I'm not able to draw it in a different way in comparison of the others actions. Setting the font of the action doesn't work. I've also tried to implement the method initStyleOption(QStyleOptionMenuItem *option, const QAction *action) in this way but doesn't work. Debugging I see that this method is never called.
void TitleMenu::initStyleOption(QStyleOptionMenuItem *option, const QAction *action) const
{
if(action == titleAction)
{
QFont f;
f.setBold(true);
f.setPointSize(10);
option->font = f;
}
else
QMenu::initStyleOption(option, action);
}
Moreover I want that the title of a menu have also a different backgound.
Is it all possible?
Thanks
Fabio.

it's not virtual. no chance. :(

yeah. Just keep in mind that you are breaking desktop integration and maybe
style awareness.
QMenu is a Qwidget, so you can reimplment paintEvent and move the actions down
a litle to display your title.Transformation might do the trick. also
reimplemt the sizehint to reflect your title size.

Or you can insert "dummy" QAction and set different font to it
(setFont) and make it disabled. Then it could look as a title. Still,
you may have to alter the paintEvent to draw the "title" a bit
differently (with another style/color/etc..).

It's a good idea. But what do you mean with "Transformation might do the trick"? I don't know how to move the actions down...
This is a draft of a possible implementation...
void TitleMenu::paintEvent(QPaintEvent* e)
{
//Move down the actions... (?)
QMenu::paintEvent(e);
//draw the title
}
I think the idea is correct, but I don't know how to do the first part.
