QListWidget right-mouse click

[Skizmo]

Hi,

I'm a bit puzzled. I'm trying to create a popupmenu when I right-click a QListWidget, but I can only find the itemClicked () function, and this function doesn't tell me which button is used to click. Anyone here who knows how this 'normally' works ??

Reimplement QWidget::contextMenuEvent() and use QListWidget::itemAt() to get item at given position.

Reimplement ?? You mean to say that I have to subclass it so I can create a popupmenu ?? That would be totally stupid. I thought QT tried to make it easy for us ;)

That's the default behaviour. There are a few different ways for implementing a context menu. See QWidget::contextMenuPolicy (http://doc.trolltech.com/4.2/qwidget.html#contextMenuPolicy-prop) for other possibilities. Also, this topic has been discussed several times on the forums.

create the signal / slot for the QListWidget like this..
Assuming the QListWidget is called lbUserList...


connect(lbUserList, SIGNAL(customContextMenuRequested(const QPoint &)), this, SLOT(userListMenuRequested(const QPoint &)));


Then in the slot place some code like this



void MainWindowImpl::userListMenuRequested(const QPoint & pos)
{
QPoint globalPos = lbUserList->mapToGlobal(pos); // Map the global position to the userlist
QModelIndex t = lbUserList->indexAt(pos);
lbUserList->item(t.row())->setSelected(true); // even a right click will select the item
userListMenu->exec(globalPos);
}
