[英]setVisible in Java Applet not working
I am writing a Java applet, in my applet I simply call setVisible() to control the visibility of some panels. 我正在编写一个Java applet,在我的applet中,我只是调用setVisible()来控制某些面板的可见性。
For example: 例如:
pnlAddUser.setVisible(true);
but sometimes showing panel does not work. 但有时无法显示面板。 and when I just click on the border of Applet Viewer window, the panel appears.
当我只单击Applet Viewer窗口的边框时,将出现该面板。
I used: 我用了:
but it doesn't work. 但这不起作用。
Edit: I should mention, I am using a JTree and when a TreeNode is selected, I show or hide some panels according to the type of the node. 编辑:我应该提到,我正在使用JTree,并且当选择TreeNode时,我会根据节点的类型显示或隐藏一些面板。
Please help me, Thanks. 请帮助我,谢谢。
Solved. 解决了。 Not good but it works.
不好,但是有效。
I added the code: 我添加了代码:
public void repaintAgain() {
setSize(this.getWidth() - 1, this.getHeight() - 1);
setSize(this.getWidth() + 1, this.getHeight() + 1);
}
whenever I want to repaint, use this. 每当我想重新粉刷时,都可以使用它。
