Java-删除ImageIcon? [英] Java - delete an ImageIcon?

问题描述

有什么方法可以轻松地从屏幕上完全删除ImageIcon吗?我在任何地方都找不到.

Is there any way to easily delete an ImageIcon completely from the screen? I can't find one anywhere.

ImageIcon image = new ImageIcon("candle.gif");
image.paintIcon(this, g, 150, 80)

例如，如果我以后想取消按钮时的图像"，什么是合适的代码? (不是按钮，我知道该怎么做.)

For example, if I wanted to get rid of "image" later on when a button is pressed, what would be the appropriate code? (Not for the button, I know how to do that).

推荐答案

不要重新发明轮子.绘制图标的最简单方法是使用JLabel.该代码将类似于:

Don't reinvent the wheel. The easiest way to paint an Icon is to use a JLabel. The code would be something like:

ImageIcon icon = new ImageIcon(...);
JLabel label = new JLabel( icon );
panel.add( label );

如果您不想再显示图标，则只需在按钮的ActionListener中执行以下操作即可:

If you don't want to display the icon anymore then in the ActionListener of your button you simple do:

label.setIcon( null );
