Swing: set JFrame content area size
提问by igul222
I'm trying to make a JFrame with a usable content area of exactly 500x500. If I do this...
我正在尝试制作一个可用内容区域正好为 500x500 的 JFrame。如果我这样做...
public MyFrame() {
super("Hello, world!");
setSize(500,500);
}
... 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?
...我得到一个完整大小为 500x500 的窗口，包括标题栏等，我真的需要一个大小为 504x520 的窗口来解释窗口边框和标题栏。我怎样才能做到这一点？

you may try couple of things: 1 - a hack:
你可以尝试几件事：1 - 一个黑客：
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- or Add a JPanel to the frame's content pane and Just set the preferred/minimum size of the JPanel to 500X500, call pack()
2- 或将 JPanel 添加到框架的内容窗格并将 JPanel 的首选/最小尺寸设置为 500X500，调用 pack()
- 2- is more portable
- 2-更便携

Never mind, I figured it out:
没关系，我想通了：
public MyFrame() {
super("Hello, world!");
myJPanel.setPreferredSize(new Dimension(500,500));
add(myJPanel);
pack();
}

Simply use:
只需使用：
public MyFrame() {
this.getContentPane().setPreferredSize(new Dimension(500, 500));
this.pack();
}
There's no need for a JPanel to be in there, if you just want to set the frame's size.
如果您只想设置框架的大小，则无需在其中添加 JPanel。
