将图标添加到JButton而不更改其大小

Question

I am trying to add an Icon to the JButton When I try to do this my Layout Manager (I use GridBagLayout ) resizes the button and makes it larger by the size of the icon.

Is there a way to avoid this?

You could try JButton#setPreferedSize(...)

Or you could override the paintComponent method:

JButton testButton = new JButton() {
   @Override
   protected void paintComponent(Graphics g) {
       super.paintComponent(g);
       g.drawImage(image, 0, 0, null);
   }
};

If you want to do this with multiple buttons, it would be better to make a class for it ofcourse, something like:

class ImageButton extends JButton {             
    private final Image image;                  

    public ImageButton(Image image) {           
        this.image = image;                     
    }                                           

    @Override                                   
    protected void paintComponent(Graphics g) { 
        super.paintComponent(g);                
        //drawing logic here                          
    }                                           
}

I had the same problem. Do these things:

1. Resize your image to fit the button with an image manipulating program.
   
2. use setMininumSize() and set the minimum size you want.

This will probably fix your problem.
