}thx a lot

Answer 1

man you're a god!!!!
now that work almost perfect except one thing, the JPanel only appear to me when i click where it is!!! do you have a answer for thaht???
thx a lot
The coordinates you get in JP's paintComponent() are
based on 'dessin', but the Graphics is
based on a JP so you are drawing outside the JP
components visible area.
The quick fix is to change the fillRect() and
fillOval() calls in JP.paintComponent() to be
fillRect(0, 0, w, h) and fillOval(0, 0, w, h) (replace
x and y with 0s)
There are other problems too - JP's constructor should
start with
super();and his paintComponent() should start with
super.paintComponent(g);JP's paintComponent() should be something like:
public void paintComponent(Graphics g) {
super.paintComponent(g);
if (type == 1) {
g.fillOval(0, 0, w, h);
else
if (type == 2) {
g.fillRect(0, 0, w, h);
