FontMetrics gp = this.getGraphics().getFontMetrics();
int x=gp.stringWidth("test");

but getGraphics returns always null because panel isn't visible yet. How to solve this problem ?

You should do this in one of the paint() or paintComponent() methods where the Graphics instance exists.

Or you can can create a BufferedImage and call getGraphics().
