It's fine if you want to use only one menu/action instance for your
different controls. You just need a way to know which control is triggering
the menu so that you can reference it when the action is selected. One way
to do that is to track the current context widget using "self.sender()"
when your context menu is triggered:
class MyTool(QtGui.QWidget):
def __init__(self, parent=None):
super(MyTool, self).__init__(parent = parent)
...
self._contextWidget = None
self.ui.xLineEdit.setContextMenuPolicy(QtCore.Qt.CustomContextMenu)
self.ui.xLineEdit.customContextMenuRequested.connect(self.custom_menu)
...
def set_key(self):
lineEdit = self._contextWidget
if not lineEdit:
return
...
def custom_menu(self, point):
self._contextWidget = self.sender()
self.popMenu.exec_(QtGui.QCursor.pos())
Every time you trigger the menu, you save the widget that triggered it.
Then you can reference it if an action is selected from the menu.
