java中对窗体设置快捷键程序,java中的自定义键盘快捷键

I am developing a java swing application. I want to add a keyboard shortcut say CTRL + H. This should perform the same action performed by jButton1 when clicked.

This shortcut should behave in the same way even when jButton1 is not focused.

I tried with KeyEventDispatcher, but it doesn't seem to be working for me. Is there any other way?

Ok - First I don't think there is a way to set application wide shortcuts in Java Swing(Refer this question). But for a component it is possible.

You have to use a create an Action for the KeyStroke. But for Windows I found this library very helpful.

{

KeyStroke cancelKeyStroke = KeyStroke

.getKeyStroke((char) KeyEvent.VK_ESCAPE);

Keymap map = JTextComponent.getKeymap(JTextComponent.DEFAULT_KEYMAP);

map.addActionForKeyStroke(cancelKeyStroke, cancelKeyAction);

}

private static Action cancelKeyAction = new AbstractAction() {

public void actionPerformed(ActionEvent ae) {

Component comp = (Component) ae.getSource();

Window window = SwingUtilities.windowForComponent(comp);

if (window instanceof Dialog) {

window.dispose();

} else if (comp instanceof JTextComponent

&& !(comp instanceof JFormattedTextField)) {

JTextComponent tc = (JTextComponent) comp;

int end = tc.getSelectionEnd();

if (tc.getSelectionStart() != end) {

tc.setCaretPosition(end);

}

}

}

};
