To make JApplet repaint

[maja neskovic]

On my JApplet I have one JTextArea. I also have variable counter. I would like to display different text on JTextArea for different values of variable counter.

For example, if counter is 5, to display "You are on 5th assignment".

I have written code for that, but my JAplet does not repaint. How to set that?

That's impossible to say without seeing the code.

Here is the code:

                  switch(counter_stranice){
                    case 1:{
                        text_area.setText(text_area_set_text_1);
                        TestAplet.this.repaint();
                        break;
                    }
                    case 2:{
                        text_area.setText(text_area_set_text_2);
                        TestAplet.this.repaint();
                        break;
                    }
                    case 3:{
                        text_area.setText(text_area_set_text_3);
                        TestAplet.this.repaint();
                        break;
                    }
                    case 4:{
                        text_area.setText(text_area_set_text_4);
                        TestAplet.this.repaint();
                        break;
                    }
                }  

It works this way, I think I made it.

Glad to hear you got it to work. Note that instead of "TestAplet.this.repaint()" you can just write "repaint()".

[Rob Camick]

You don't even need the repaint() method.

Swing components are smart enough to repaint themselves automatically when the value of a property (like setText) is changed.

OK. Thank you
