[SOLVED] QTextEdit createStandardContextMenu

HornetMaX

Hi all,
I have a main window with a menu bar with an empty menu (let's call it mnEditCmds).

I aslo have a dockWidget with a QTextEdit: when I right-click on it I show a custom context menu that has all the actions in the standardContextMenu plus others that I add manually (using the customContextMenuRequested signal), like this:

@void MainWin::on_textEd_SCL_customContextMenuRequested(const QPoint &pos)
{
QMenu *scMn = m_UI->textEd_SCL->createStandardContextMenu(pos);

QMenu *cMn = new QMenu();
cMn->addMenu(m_UI->mnSoundFile);
cMn->addSeparator();
QMenu *mnEC = cMn->addMenu(m_UI->mnEditCmds->title());
mnEC->addActions(scMn->actions());

cMn->exec&#40;m_UI->textEd_SCL->mapToGlobal(pos&#41;&#41;;

delete(scMn&#41;;
delete(cMn);

}@

What I want to do is to have all the actions of the standardContextMenu also in my mnEdit.
So I use a slot on the aboutToShow signal, like this:

@void MainWin::mnEditCmds_abouttoshow()
{
QMenu *mnEditCmds = m_UI->mnEditCmds;
qDeleteAll(mnEditCmds->actions());

QMenu *cMn = m_UI->textEd_SCL->createStandardContextMenu();
// cMn->setAttribute(Qt::WA_DeleteOnClose);

mnEditCmds->addActions(cMn->actions());
delete(cMn);

}@

Now my problem is that if I delete cMn as in the code above, my mnEditCmds shows no child actions when I click on it, because I deleted them deleting cMn. Fine.

But if I don't delete cMn and set its property WA_DeleteOnClose, will the code leak ? The context menu cMn is actually not shown, so I don't know if it gets a close signal (triggering its deletion). I'm actually under the impression it doesn't. So it leaks. Maybe :)

What'd be the right way to do that ?

MaX.

How about this (not tested)?
@
connect(mnEditCmds , &QMenu::aboutToHide, cMn, &QMenu::deleteLater);

IT.JUST.WORKS. Brillant solution.
