I am developing a simple swing app in which I have a main window with three buttons. When I click on the first button it opens new window of (200,200) dimension. When I click on the second button, the newly opened window's height should get increased and when I click on third button height should get decreased. Can you help me with code....

推荐答案

您可以在要调整大小的新打开窗口上执行以下操作:

you could do the following on the newly opened windows which you want to resize:

JFrame fr=getNewlyOpenendWindowReference(); // get a reference to the JFrame
fr.setSize(fr.getSize().getWidth() + 10,fr.getSize().getHeight() + 10);
fr.repaint();

这应该会在每次调用时将 JFrame 的长度和宽度增加 10 个像素.

this should increase the size of the JFrame length and widthwise by 10 pixels per call.
