I have a set of JLabel
s, each containing a letter (via seText()), opaque and background set to white, on a JPanel
with a GridLayout
so the labels are forming a table.
I am doing a simple animation of highlighting certain rows and columns then there intersection. I can use the setBackground()
of labels for this purpose, but thought I'd have more "choices" if a was able to use a Graphics
object (maybe drawing a circle around intersection, then clearing it).
I tried to extend JLabel
, or drawing on the JPanel
directly(using getGraphics()
in a method) but it didn't work, I think the drawing is behind the labels in this case. I can't figure out where should the "painting" code be placed in either case, nothing appeared on the screen.
in short, a method like the following, can be used to draw on top of labels?
should it be a JLabel or a JPanel method?
public void drawsomething() {
Graphics2D g2d = (Graphics2D) getGraphics();
g2d.fillRect(100, 100, 100, 100);
}
What if you override paintChildren()
?
protected void paintChildren(Graphics g) {
super.paintChildren(g);
//paint your lines here
}
