问题描述

我正在尝试制作一个具有500x500的可用内容区域的JFrame.如果我这样做...

I'm trying to make a JFrame with a usable content area of exactly 500x500. If I do this...

public MyFrame() {
    super("Hello, world!");
    setSize(500,500);
}

...我得到一个全尺寸为500x500的窗口，包括标题栏等.在这里，我确实需要一个尺寸约为504x520的窗口，以说明该窗口的边框和标题栏.我该如何实现?

... I get a window whose full size is 500x500, including the title bar, etc., where I really need a window whose size is something like 504x520 to account for the window border and titlebar. How can I achieve this?

推荐答案

您可以尝试以下几种方法:1-骇客:

you may try couple of things:1 - a hack:

public MyFrame(){
 JFrame temp = new JFrame;
 temp.pack();
 Insets insets = temp.getInsets();
 temp = null;
 this.setSize(new Dimension(insets.left + insets.right + 500,
             insets.top + insets.bottom + 500));
 this.setVisible(true);
 this.setResizable(false);
}

2-或将JPanel添加到框架的内容窗格，然后只需设置首选/最小尺寸JPanel的大小为500X500，请调用pack()

2- orAdd a JPanel to the frame's content pane and Just set the preferred/minimum sizeof the JPanel to 500X500, call pack()

2-更便携
