[SOLVED] QTextEdit createStandardContextMenu
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(m_UI->textEd_SCL->mapToGlobal(pos)); delete(scMn); 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:
QMenu *mnEditCmds = m_UI->mnEditCmds;
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 ?
How about this (not tested)?
connect(mnEditCmds , &QMenu::aboutToHide, cMn, &QMenu::deleteLater);
IT.JUST.WORKS. Brillant solution.
Thanks Chris !
