How to create a context menu

LT-K101

I want a context menu to work with a specific TableWidget but when I click anywhere in the application the context menu pops up. Below is the code I tried, Please I need assistance of how to get this done.

 def contextMenuEvent(self, event):
        contextMenu = QMenu(self)

        addAction = contextMenu.addAction("Add New")
        editAction = contextMenu.addAction("Edit")
        deleteAction = contextMenu.addAction("Delete")


        action = contextMenu.exec_(self.mapToGlobal(event.pos()))

        if action == editAction:
           
            self.updatePersonID()
            self.Info_Updatesearch()
         

        if action == deleteAction:
            self.singleClick_searchDelete()
         

        if action == addAction:
            self.ui.stackedWidget.setCurrentWidget(self.ui.personalInformation_page)

I really ought not have to do this, you should know this, it is common sense.

If you want customContextMenuRequested signal to be raised you have to tell widget to do so when you set up the connection:

self.ui.tableWidget.setContextMenuPolicy(Qt.CustomContextMenu)
self.ui.tableWidget.customContextMenuRequested.connect(self.openMenu)

I guess this is in your main window (you did not mention this)?
You need to subclass QTableWidget and override contextMenuEvent there...
Or do it in main window but check which widget is under the mouse cursor and only show pop-up if it is over your table widget.

@jsulm I tried the code below but it does not seem working , I think am doing something wrong.

self.ui.tableWidget.customContextMenuRequested.connect(openMenu)
def openMenu(self, position):
    self.ui.tableWidget.setContextMenuPolicy(Qt.CustomContextMenu)

    menu = QMenu()
    editAction = menu.addAction('Edit')

    action = menu.exec_(self.ui.tableWidget.mapToGlobal(position))

    if action == editAction:
       self.ui.stackedWidget.setCurrentWidget(self.ui.personalInformation_editpage)

 self.ui.tableWidget.show()

You should look at and show the error message!

openMenu() is a method in a class. So:

self.ui.tableWidget.customContextMenuRequested.connect(self.openMenu)

@JonB I did correction as you showed self.ui.tableWidget.customContextMenuRequested.connect(self.openMenu) but the contextMenu is still not popping up.

@LT-K101
Since you set self.ui.tableWidget.setContextMenuPolicy(Qt.CustomContextMenu) only inside def openMenu(), how do you expect the self.ui.tableWidget.customContextMenuRequested signal to be raised to call self.openMenu() in the first place?

@JonB Please could you direct me on how to achieve this, this is the first time I'm trying this.
