来自图像的JButton [英] JButton from image

问题描述

我想从图像中制作JButton。但当我这样做时：

  private void AddMainActionsButtons（Container powZawartosci）{
 JPanel mainActionButtons = new JPanel（ ）; 
 JButton applyButton = createImageButton（obrazki / apply.png）; 
 mainActionButtons.add（applyButton）; 
 powZawartosci.add（mainActionButtons）; 
 mainActionButtons.setBounds（150,530,400,90）; 
} 
 
 private JButton createImageButton（String imagePath）{
 ImageIcon icon = uploadImage（imagePath，）; 
 JButton button = new JButton（icon）; 
 
返回按钮; 
} 
  

JButton看起来不好，因为图像在按钮组件内部，实际上我得到了图像上的图像。如何创建与我的图像一样大的JButton，以及如何通过图像100％覆盖它。换句话说：如何使我的图像成为按钮？

解决方案

你需要通过删除按钮来占用空间边界。有关详细信息，请参见，了解使用更简单图像的版本 JToggleButton 实例。

I want to make JButton from image. But when i do it like this:

private void AddMainActionsButtons(Container powZawartosci){
  JPanel mainActionButtons = new JPanel();
  JButton applyButton = createImageButton("obrazki/apply.png");
  mainActionButtons.add(applyButton);
  powZawartosci.add(mainActionButtons);
  mainActionButtons.setBounds(150,530,400,90);
}

private JButton createImageButton(String imagePath){
  ImageIcon icon = uploadImage(imagePath,"");
  JButton button = new JButton(icon);

  return button;
}

JButton looks bad, because image is inside button component, and in fact I got image on image. How can I create as big JButton as my image, and how to cover it by image in 100%. In other words: how to make my image be a Button?

解决方案

You need to take the space out of the buttons by removing the border. See this answer for details.

Seen above is the single image split into 9 parts. The N/S/E/W are buttons (East is activated - shown with a red border) and the rest are labels - each containing the relevant part of the original image.
