Question

I have a frame which is multi tabbed and I have to set shortcuts to certain buttons under different tabs, but they have to use the same key. For example:

Under tab1, I have a "Do that" button which should react to F1 key, but if I were to switch to tab2, I should have a "Do this" button which should also react to F1 button but the action on tab1 shouldn t be fired.

我尝试将 keyliber 添加到制表符/密钥/黑帮中,但是,如果我按 F1 键,它仍然是第一个被开除的动作。

但我认为是因为我使用一个控制关键事件的开关,例如 case KeyEvent.VK_F1:my button1.do kick ();

那么我该如何在不同的标签下将动作分开反应呢?是否有办法让焦点化的标签或其它东西成为例呢?

请注意

编辑: Swing 动作的一些代码 :

    private class SwingAction extends AbstractAction {
    public SwingAction() {
        putValue(NAME, "mybutton");
        putValue(SHORT_DESCRIPTION, "Some short description");
    }
    public void actionPerformed(ActionEvent e) {
        mybutton.getInputMap().put(KeyStroke.getKeyStroke("F1"),"pressed");
        mybutton.getActionMap().put("pressed",mybutton.doClick());

    }
}

我得到:

The method put(Object, Action) in the type ActionMap is not applicable for the arguments (String, void) error, ( sorry a Java/Swing newbie here)

Answer 1

使用

< a href=>" rel=“no follow” rel="nofolpol"JBoutton#setactoction
" rel="nofollow" >KeyBindings (用于 F1 ),其输出到 Swing Action ,在 Action 内,您必须调用 < a href=>"http://docs.oracle.com/javase/7/docs/api/javax/swind/AbstractButton.html#doclick%28%29" rel=“no folpt>>>JButton#doClick()
don t 使用KeyListener for Swing JComponents, ever

Answer 2

将 KeyStroke 绑定为按钮 s doClick () 具有视觉和听觉反馈的优势;但是,正如你所观察到的, doClick () 并不是一个 Action 。相反,创建一个 Action ,引用给定按钮s doClick () 方法,并将其绑在所需的 KeyStroke 上,正如此所显示的, https://sites.google.com/site/drjohnbmatthews/keypad-panel" rel=“nofol”>>>example 。
