setMaximumSize not working in java
提问by thejh
I hava a java program with a JFrame
我有一个带有 JFrame 的 java 程序
I am using absolute positioning
我正在使用绝对定位
here is my main function
这是我的主要功能
public static void main(String[] args) {
ape Ape = new ape();
Ape.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Ape.setSize(1000,1000);
Ape.setMinimumSize(new Dimension(1000,1000));
Ape.setMaximumSize(new Dimension(1000,1000));
Ape.setVisible(true);
}
When I run the program I try to resize it and make the window smaller but I can't
当我运行程序时，我尝试调整它的大小并使窗口变小，但我不能
when I try to make the window bigger it works fine I basicly skips the setMaximumSize()function
当我尝试使窗口变大时，它工作正常，我基本上跳过了该setMaximumSize()功能
I have read around and aparently this has happened before
我已经阅读了，显然这以前发生过
is this a known bug?
这是一个已知的错误？
if so I heard I could make a Window Listener, when I tried it I implemented the functions that WindowListener needed but could not find anything to solve my problem
如果是这样，我听说我可以制作一个 Window Listener，当我尝试它时，我实现了 WindowListener 需要的功能，但找不到任何东西来解决我的问题
please try this yourself and see what happens...
请自己尝试一下，看看会发生什么......
thanks in advance
提前致谢
PS... please don't laugh about the names I give my classes... :)
PS...请不要嘲笑我给我的课程起的名字... :)

Maybe you could use
也许你可以用
Ape.setResizable(false)
instead?
反而？
PS: It's a convention to give classes names that start with a capital letter and variables ones with a small letter, not vice versa.
PS：类名以大写字母开头，变量名以小写字母开头是一种约定，反之亦然。

In my case I used the following and it worked:
在我的情况下，我使用了以下内容并且它有效：
Dimension newDim = new Dimension(width, height);
label.setMinimumSize(newDim);
label.setPreferredSize(newDim);
label.setMaximumSize(newDim);
label.setSize(newDim);
label.revalidate();

I fixed it like this :
我是这样修的：
frame.setBounds(0, 0, 1480, 910);
frame.setMinimumSize(new Dimension(1200, 799));
frame.setMaximumSize(new Dimension(1480, 910));
frame.setPreferredSize(new Dimension(1480, 910));
frame.setLocationRelativeTo(null);
frame.addComponentListener(new ComponentAdapter() {
@Override
public void componentResized(ComponentEvent e) {
double w = frame.getSize().getWidth();
double h = frame.getSize().getHeight();
if(w > 1480.0 && h > 910.0){
frame.setSize(new Dimension(1480, 910));
frame.repaint();
frame.revalidate();
}
super.componentResized(e);
}
});

For Netbeans user try to set values for the maximum frame in setMaximizedBounds() click in properties of frame you will find an option to define values for setMaximizedBounds.
对于 Netbeans 用户，尝试在 setMaximizedBounds() 中设置最大帧的值，单击帧的属性，您将找到一个选项来定义 setMaximizedBounds 的值。
