JLabel on JButton does always show ...

Question

Hi guys, i tried the following stuff
myButton.setPreferredSize(new Dimension(100,60));
          myLabel = new JLabel("");
          myLabel.setPreferredSize(myButton.getPreferredSize());
          myButton.add(myLabel);the problem is whenever i access the
myButton.myLabel.setText("sometext"); via my actionlistener it sets its text to ... instead of showing me its content
and i am sure the content would fit as its a THREE CHAR code...
thanks in advance
PS: i generate a grid of buttons with " " caption, when someone clicks the button the text on the button changes! (i use JLabels cause i want to exchange the changing text to images later!)

Answer 1

i moved one step further and put the images in already
works like charm and does what i expect it to do
i saw that JButton can hold an icon without jlabel (dunno why i overlooked this the day before...)
you are right, i can add the actionlistener to the class and assign the class itself.
further i replaced Applet by JApplet and the refrehs works with any more line of code... only had to change the import and add the J infront of Applet nice
thanks for your help!!
here is my 'final' code
