Crossing out the Icon

no

I need smth like this:

..................

ImageIcon oldValue = jButton1.getValue(Action.SMALL_ICON);

jButton1.putValue(Action.SMALL_ICON, striking(oldValue ));

...................

public ImageIcon striking(ImageIcon icon){

ImageIcon strikethroughIcon = icon;

// here you should strikethrough icon

return strikethroughIcon ;

}

As said above, the best way for this to work would be to have two images.

You load up the button with image 1 (the normal image), then you add an event handler to it.

In the event handler code you put:

button.setIcon( yourCrossedOutIcon );

Which would then make your button appear as image 2 (the crossed out image).

Skeleton:

class StrikeTIcon extends Icon {

Icon original;

public StrikeIcon(Icon original) {

this.original = original;

}

public void paintIcon(...) {

this.original.paintIcon(...);

Graphics g2 = (Graphics2D)g.create();

g2.setColor(Color.red);

g2.drawLine(0,0,width,height);

g2.dispose();

}

}

Change the stroke and the line coordinates to match your strikethrough design. Delegate all the other Icon methods to the original icon as well.

Unfotunatly - NO

your code

public void paintIcon(Component c, Graphics g, int x, int y) {

Graphics2D g2 = (Graphics2D) g.create();

g2.setColor(Color.red);

//possibly here mistake

g2.drawLine(0, 0, icon.getIconWidth(), icon.getIconHeight());

g2.dispose();

icon.paintIcon(c, g, x, y);

}

do this:

and of course without striking through it looks

right answer:

public class StrikethroughIcon

extends ImageIcon {

public StrikethroughIcon(ImageIcon icon) {

super(icon.getImage());

}

public void paintIcon(Component c, Graphics g, int x, int y) {

super.paintIcon(c, g, x, y);

try {

Graphics2D g2 = (Graphics2D) g;

g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,

RenderingHints.VALUE_ANTIALIAS_ON);

} catch (Exception ignore) { }

g.setColor(Color.red);

g.fillPolygon(new int[]{x,x+3,x+getIconWidth(), x+getIconWidth()-3}

,new int[]{y+getIconHeight(), y+getIconHeight(),y, y},4);

}

}
