JDialog allow user to only change width of the dialog

我有一位犹太人民主党,我想说的是,血汗是可憎的,但不是高潮。

这是我的现行法典:

addComponentListener(new ComponentAdapter() {
    @Override
    public void componentResized(ComponentEvent e) {
        setLocation(getLocation().x, getLocation().y + (getHeight() - staticHeight));
        setSize(new Dimension(getWidth(), staticHeight));
        super.componentResized(e);
    }
});

问题在于,在窗户重新缩编后,该代码便被打上。使窗户变现,然后回落。

当用户试图冲破窗户的高度时,我就这样做了。

你可以直接停止转播,

转播限制为屏幕尺寸

根据AbsoluteLayout,有 d脏的黑板,我不建议使用

如果在重新分配期间出现任何浮现或冻结,则会发生阻塞

Answer 2

looks like you cant. there s a setResizable() method but its all-or-nothing.
you could try mitigating this by using a layout inside your JDialog so that your content remains the same height regardless of the JDialog height
or perhaps (a bit more radical) set it as not resizable and implement your own mouse listener for resizing yourself ? that way you could have full control

在等待一段时间后,我找不到任何真正令人满意的解决办法。我认为,转解辩是直接在本组织一级处理的问题,因此,你只能说,你想要它完全不可行或完全不可行。

The code below will always prevent the dialog from being bigger, but as the user resize the dialog, the borders of the dialog still move.

rad也提出的另一个选择是,防止转基因,并设置一个含有摩擦听众的陈规律,以便倾听摩擦,并相应地进行消化。然而,我认为这不会对使用者感到非常本土(我不认为你能够追捕迪亚洛边界上的事件)。

Here try this code example, that s how you set the JDialog to not have vertical Resizing. Though I really doesn t want to take credit for this, the whole credit goes to the creator of this program which is "Darryl Burke" the link to the program is here.

import java.awt.*;  
import java.awt.event.*;  
import javax.swing.*;  

public class WidthResizeableDialog {  

  Robot robot;  
  static final int HEIGHT = 400;  
  Point lastLocation;  

  public static void main(String[] args) {  
    SwingUtilities.invokeLater(new Runnable() {  

      @Override  
      public void run() {  
        new WidthResizeableDialog().makeUI();  
      }  
    });  
  }  

  public void makeUI() {  
    try {  
      robot = new Robot();  
    } catch (AWTException ex) {  
      ex.printStackTrace();  
    }  
    final JDialog dialog = new JDialog();  
    dialog.setSize(400, HEIGHT);  
    dialog.setLocationRelativeTo(null);  
    dialog.addWindowListener(new WindowAdapter() {  

      @Override  
      public void windowClosing(WindowEvent e) {  
        System.exit(0);  
      }  
    });  
    dialog.addComponentListener(new ComponentAdapter() {  

      @Override  
      public void componentMoved(ComponentEvent e) {  
        SwingUtilities.invokeLater(new Runnable() {  

          @Override  
          public void run() {  
            lastLocation = dialog.getLocation();  
          }  
        });  
      }  
    });  
    dialog.getRootPane().addComponentListener(new ComponentAdapter() {  

      @Override  
      public void componentResized(ComponentEvent e) {  
        int height = dialog.getHeight();  
        if (robot != null && height != HEIGHT) {  
          robot.mouseRelease(InputEvent.BUTTON1_MASK);  
          dialog.setLocation(lastLocation);  
          dialog.setSize(dialog.getWidth(), HEIGHT);  
        }  
      }  
    });  
    dialog.setVisible(true);  
  }  
}
