How to use cut/copy/paste QKeySequence actions?

Alexey Serebryakov

Hi guys,
i have implementation of copy/cut/paste items in my QTreeView-derived widget. Now I would like to provide these actions with StandardKeys.
I've created actions with QKeySequence::Cut, QKeySequence::Copy, QKeySequence::Paste and added to my context menu. Great!. But shortcuts does not work.
Then I've re-implemented MyTreeView::eventFilter like this:

bool MyTreeView::eventFilter(QObject *, QEvent *event) {
... // something else
case QEvent::KeyPress: {
    if (auto *keyEvent = dynamic_cast<QKeyEvent*>(event)) {
        if (keyEvent->matches(QKeySequence::Cut)) {
            cut();
        } else if (keyEvent->matches(QKeySequence::Copy)
// and so on
    }
}

Ok, it work. But what about the issue with passed QKeySequence when I've created actions?

Thanks a lot.

Hi,

You might want to rather filter on QShortcutEvent.

@SGaist I see but look at https://doc.qt.io/qt-5/qshortcutevent.html#details.

Also I thought that was automatically when I've created action.

Indeed, it's usually associated with a QAction however your code uses eventFilter.

@SGaist ok, please could you suggest me great solution?

Use actions and connect them to the cut, copy, paste slots.
