JTextField中的焦点侦听器

[英]Focus listener in JTextField

如何在不使用TAB键的情况下将光标从JTextField1移至JTextField2如何使用FOCUS LISTENER进行此任务

No need to use the focus listener. 无需使用焦点侦听器。 Depending on what you code does, you may be able to use this: 根据您的代码功能,您可能可以使用以下代码:

field2.requestFocus();

"requestFocusInWindow()" is probably the Swing API you're looking for. “ requestFocusInWindow()”可能是您正在寻找的Swing API。

Here are several examples of several different "focus" related tasks: 这是几个与“焦点”相关的不同任务的几个示例:

Request Focus inside a Window 在窗口内请求焦点

set Focus and all workaround isn't easy job in the most complex application, if is there attached DocumentListener or Jtextfield1/JTextField2 had already implemented FocusListene r that you have to wrap that inside invokeLater() your code for setFocus form/to should be 在最复杂的应用程序中设置Focus并进行所有变通并不是一件容易的事,如果附加了DocumentListenerJtextfield1/JTextField2已经实现了FocusListene r,则必须将其包装在invokeLater()用于setFocus form / to的代码应该是

    Runnable doRun = new Runnable() {

        @Override
        public void run() {
            myTextField2.requestFocus();
            myTextField2.setText(myTextField2.getText());
            myTextField2.selectAll();
        }
    };
    SwingUtilities.invokeLater(doRun);

very complicated are if you needed move and set Focus betweens two or more Top-level Coantainers 如果您需要在两个或多个顶级协作者之间移动并设置Focus则非常复杂

field2.requestFocus(); ? or 要么

public boolean requestFocusInWindow()
