[FIXED] How to handle keyPressEvent Escape and Ctrl+C at the same time (PySide)?

Issue

In a Pyside program, I want to use Ctrl+C for copy in my tableWidget.

I added a short-cut in QtDesigner, but it not works.

In mainGui.py

self.actionCopy.setShortcut(QtGui.QApplication.translate("mainDialog", "Ctrl+C", None, QtGui.QApplication.UnicodeUTF8))

I found the key is captured by overridden keyPressEvent (just for Escape at first). It could capture single "Key_Control" but cannot capture Ctrl+C. Below is my code:

def keyPressEvent(self, event):
    # Re-direct ESC key to closeEvent
    print(event)
    if event.key() == Qt.Key_Escape:
        self.close()
    elif event.key() == QKeySequence.Copy:
        self.actionCopy.trigger()

How could I do to make it capture Ctrl+C or let it pass to QtDesigner's short-cut

Solution

You don't have to override the keyPressEvent. You started good with the shortcut but I need more code to tell you where you went wrong. The workflow should be:

1. Create an action from Ctrl+C

2. Connect that action with a function of you main widget

3. In the function of your main widget that is connected with the Ctrl+C you gather all the information you need and place them in the clipboard.

But, as I said, I need more code so I can detect the problem.

Update:

After line 68 in your code, add the line:

self.tableWidget.addAction(self.actionCopy)

You have to add the action to the tableWidget also, not just to the main window.
