如何重新加载JPanel？ [英] How to reload a JPanel?

问题描述

我是一个java新手......我需要知道如何重新加载一个 JPanel ？我扩展了 JPanel 类，并在Applet中创建了一个将在 cardlayout 中运行的面板。用户在此面板中单击按钮后，我希望此面板重新加载/刷新。我试着在 revalidate （）和重绘（）方法（我不太了解的方法） ActionListener 按钮但没有任何反应。任何人都可以了解如何正确刷新整个面板？

I'm a java newbie... I need to know how to reload a JPanel? I extended the JPanel class and created a panel that will run in a cardlayout in an Applet. I want this panel to reload/refresh after the user clicks a button in this panel. I tried including the revalidate() and repaint() methods (methods I don't understand well) in the ActionListener for the button but nothing happened. Can anyone throw some light on how to correctly refresh the whole panel?

_panel.revalidate();
_panel.repaint();
