设置 JMenuItem 加速器文本，而不仅仅是操作

Question

For my swing application a JMenuItem has the accelerator set like this:

JMenuItem numFieldsMI = new JMenuItem("Set Number of Fields");
numFieldsMI.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_3,
         ActionEvent.CTRL_MASK+ActionEvent.SHIFT_MASK));

This, when the GUI is intitialized, makes the text next to the menu item read "Ctrl+Shift+3" but of course the intent is that the text be "Ctrl+#". How can I do this?

Answer 1

Change

numFieldsMI.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_3,
         ActionEvent.CTRL_MASK+ActionEvent.SHIFT_MASK));

to

numFieldsMI.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_3,
         ActionEvent.CTRL_MASK ***|*** ActionEvent.SHIFT_MASK));
