Adding contextmenu for QTreeWidgetItem .

BibekKumar

Inside constructor

@connect(ui.UserSpecificMaterial_treeWidget, SIGNAL(customContextMenuRequested(const QPoint &)),this, SLOT(ContMenu(const QPoint &)));@

Inside slot

@void MyContMenu::ContMenu(const QPoint &pos)

{
QTreeWidgetItem *item = ui.UserSpecificMaterial_treeWidget->itemAt(pos);
if (!item)
return;
QMenu *menu = new QMenu(ui.UserSpecificMaterial_treeWidget);
myAction = menu->addAction("Remove");
myAction->setIcon(QIcon(QString::fromUtf8("Resources/Remove.png")));
myAction->setShortcut(tr("Ctrl+D"));
myAction->setStatusTip(tr("Remove the respective material from the User DB"));
menu->exec(ui.UserSpecificMaterial_treeWidget->viewport()->mapToGlobal(pos));
/---code to remove the item ./
}
@
In the above code whenever i right click on the QTreeWidgetItem it will show me the contextmenu having a single menuitem named Remove . What i want is whenever the user click on that remove menuitem at that time only it should remove that QTreeWidgetItem from the qtreewidget . but in the above code after rigtclick even if i click on any part of the UI it removes the respective QTreeWidgetItem from the treewidget , which i want to avoid .

Thankss in advance .

doesnt' QTreeWidget::itemAt (const QPoint & p) helped? you only need to have it kept on private pointer then use it when QMenuItem has triggered().

Try This:
@
QTreeWidgetItem *item = ui->fileList->itemAt(pos);
if (!item)
return;
QMenu menu = new QMenu(ui->fileList);
QAction myAction = menu->addAction("Remove");
myAction->setIcon(QIcon(QString::fromUtf8("Resources/Remove.png")));
myAction->setShortcut(tr("Ctrl+D"));
myAction->setStatusTip(tr("Remove the respective material from the User DB"));
myAction = menu->exec(ui->fileList->viewport()->mapToGlobal(pos));
if(myAction == NULL) return;
on_deletefile_clicked();

Or make it a signal in your QTreeView like the following:

@void MyTreeView::mousePressEvent(QMouseEvent *me)
{
QModelIndex index;
if (me->button() == Qt::RightButton) {
index = indexAt(me->pos());
if (index.isValid()) {
emit doPopup(index,me->globalPos());
}
}
else
QTreeView::mousePressEvent(me);
}
@
Connect the signal to your class:
@ connect(myFieldsTree,SIGNAL(doPopup(const QModelIndex &,const QPoint &)),this,SLOT(popupMenuSlot(const QModelIndex &,const QPoint &)));
@
Then in your slot loooks like this:

void MessageWindow::popupMenuSlot(const QModelIndex &,const @QPoint &p)
{
popupMenu->popup(p);
}@
