[Qt-interest] QtreeWidget and right-click

[Andreas Diehl]

Hello.

You can overwrite contextMenuEvent(QContextMenuEvent* e) in your QTreeWidget class and show a custom QMenu. To find the QTreeWidgetItems that are affected you can call
 QTreeWidget::selectedItems()  or
 QTreeWidget::itemAt(const QPoint &p) and give it the point from the event, like:

void MyTreeWidget::contextMenuEvent(QContextMenuEvent* event)
{
   QTreeWidgetItem*        item;
   QList<QTreeWidgetItem*> selected = this->selectedItems();
   if (selected.isEmpty())
     item = this->itemAt( event->pos() );

   //show QMenu
   //do s.th. with the items
} 

Read the QMenu API for more informations on how to show it as a context popup. QMenu::exec(...) looks fine.

Regards,
	Andreas

Betreff: [Qt-interest] QtreeWidget and right-click


Hi all

I'm a bit new to Qt.
I've successfully put in place an app based on a QTreeWidget and now I'd like to be able to right-click on any (or several) QtreeWidgetItems and have a menu appear with several actions.

How to go about doing this ?
