I need to create a context menu on right clicking at my window. But I really don't know how to achieve that.
Are there any widgets for that, or I have to create it from the beginning?
Programming language: Python
Graphical lib: Qt (PyQt)
To create a menu for a PyQt5 program we need to use a QMainWindow. This type of menu is visible in many applications and shows right below the window bar. It usually has a file and edit sub menu. The top menu can be created with the method menuBar().
First, we define the comboBox, then we add a bunch of options, then we move the comboBox (a drop down button). When the combo box has a choice, it will take the string version of the choice, and run self.
In Microsoft Windows, pressing the Application key or Shift+F10 opens a context menu for the region that has focus.
I can't speak for python, but it's fairly easy in C++.
first after creating the widget you set the policy:
w->setContextMenuPolicy(Qt::CustomContextMenu);
then you connect the context menu event to a slot:
connect(w, SIGNAL(customContextMenuRequested(const QPoint &)), this, SLOT(ctxMenu(const QPoint &)));
Finally, you implement the slot:
void A::ctxMenu(const QPoint &pos) {
QMenu *menu = new QMenu;
menu->addAction(tr("Test Item"), this, SLOT(test_slot()));
menu->exec(w->mapToGlobal(pos));
}
that's how you do it in c++ , shouldn't be too different in the python API.
EDIT: after looking around on google, here's the setup portion of my example in python:
self.w = QWhatever();
self.w.setContextMenuPolicy(Qt.CustomContextMenu)
self.connect(self.w,SIGNAL('customContextMenuRequested(QPoint)'), self.ctxMenu)
