关于pyqt5手动热键

Question

I try myself to write a shortcut sample about the menubar, but I got some issue about it. I have a File(&F) on the menubar, and in the File(&F) there is a Save File (Ctrl + S) item, I want to know that why I can't use the shortcut with Ctrl + S after I press Alt + F

menuBar = self.menuBar()
fileMenu = menuBar.addMenu("&File")
self.fileMenu .addAction(self.SaveFileBt)
self.SaveFileBt.setShortcut("Ctrl+S")

Answer 1

In the example below, you have three ways to invoke the save action .

1. Press the corresponding menu items as shown in the image.

2. Use the keyboard shortcut Ctrl+S

3. Use the keyboard shortcut Alt+F+S
