let me explain you exactly what is working and not, i have 4 buttons , one for drawing rectangles , other for drawing lines , other for clear all the rectangles and lines and other fro drawing text inside rectangles.I draw first rectangles and lines but when i change the button , drawing text, it draws text but when i change the button to dtraw another rectangle then the textarea dissapear and if i press the clear button to clear all , it still remains there...
this is the main class from where i call the rest.

Methods
PHP Code:
public void RecrangleTest()
{
//Do nothing in the constructor of the applet
}
public void init()
{
setLayout(new FlowLayout());
//Create and Add the buttons

// a.removeAll();
//finally, call repaint()
// remove(a);
repaint();

Still methods but here are just Mouse events
PHP Code:

//So set these mouseUp coordinates to set the end position.
//Then update the Vector count.
endpos = new Point(x,y);

Sorry but i dont know how to do it more than this. If u need the other classes let me know. I did my best. If its not ok tell how i must do and i will
