带有图标和文本但隐藏文本的 JButton

Question

For automatic test purposes is a must to have the text set because is the identification used by robot to navigate though screens. I need to create a JButton with text and icon but only show the icon.

I have tried several things:

1. use of setHideActionText(true) :

    jButton button = new JButton(icon); jButton.setHideActionText(true); jButton.setText(_messageManager.getMessage(messageKey));

2. setHoritzontalTextPosition

3. setVerticalAlignment

but none worked.

Anyone has any idea on how to solve this?

Answer 1

I need to create a JButton with text and icon but only show the icon.

You could have possibly used setActionCommand()

jButton.setActionCommand("Button 1");

Or, you may also use setName()

jButton.setName("Button 1");

Answer 2

You want to have the text only in the test environment but not in production?

Then you could so something like this:

setText("");
if(test)
   setText("sometext");

Answer 3

我建议将按钮文本的字体大小设置为0。如果这样不起作用，请将大小设置为尽可能低的值，并将文本颜色设置为按钮的背景颜色（您可能有之后再调整布局...）

Answer 4

You could avoid the text of the JButton completely if your work with the TooltipText:

   jButton1.setIcon(new ImageIcon(getClass().getResource("/money.png")));
   jButton1.setToolTipText("Foo");  
   ....
   jButton1.getToolTipText(); // use instead of getText()

Button text not shown with painted icons!

The code:

        Icon icon = new PlayIcon();
        JButton play = new JButton("PlayIcon with text", icon);

You expect a text with the button. But it is not shown! Maybe your icon paints itsself like this:

public class PlayIcon implements Icon ...

    public void paintIcon(Component c, Graphics g, int x, int y) {
        Graphics2D g2d = (Graphics2D) g;

        g2d.setColor(color==null ? c.getForeground() : color);
        GeneralPath path = new GeneralPath();
        path.moveTo(x + 2, y + 2);
        path.lineTo(x + width - 2, y + height / 2);
        path.lineTo(x + 2, y + height - 2);
        path.lineTo(x + 2, y + 2);
        g2d.fill(path);
        g2d.dispose(); // <===========
...

Then the problem is the dispose() call in the PlayIcon class. Remove it!

The result will be like this
