If I press two times on this Figure, then she will be rotated.
My Problem is: I dŽont know how to call the graphics elements in the
method

public void mouseDoubleClicked(MouseEvent e){}

I hofe that someone me help.
Thanks in Advance

Here is my Code:
------------------------------------------------------------ ---------
import org.eclipse.draw2d.Figure;
import org.eclipse.draw2d.Graphics;
import org.eclipse.draw2d.MouseEvent;
import org.eclipse.draw2d.MouseListener;

public class CreateGleis extends Figure implements MouseListener{

protected void paintFigure(Graphics graphics)
{
graphics.pushState();
int width = getBounds().width;
int height = getBounds().height;
int x = getBounds().x;
int y = getBounds().y;

graphics.setLineWidth(3);
//horizontal line
graphics.drawLine( x , y +height/2 , x+width , y +height/2 );
addMouseListener(this);
graphics.popState();
}

public void mousePressed(MouseEvent e) {
System.out.println("mousePressed");

}

public void mouseReleased(MouseEvent e) {
System.out.println("mouseReleased");
}

public void mouseEntered(MouseEvent e) {
System.out.println("mouseEntered");
}

public void mouseExited(MouseEvent e) {
System.out.println("mouseExited");
}

public void mouseDoubleClicked(MouseEvent e) {
//graphics.rotate(45);

}

}

Hi Mouna,

save the angle of your figure in a variable and rotate the figure
respectively in the paint method.
you cannot access the graphics object outside the paint methods.

But schould be not the Transformation written in the "
mouseDoubleClicked(MouseEvent e)" Method.
If i write rotate in the paint Methode, then will be the figure rotated
(one times and without DoubleClick)
Are there another solution, to solve this Problem?
Thanks
Mouna

Hi,
You can refer to logic example for check out performRequest with
REQUEST_DIRECT_EDIT and handle REQUEST_OPEN. like this:
@Override
public void performRequest(Request req) {
if (req.getType() == REQ_OPEN) {
doExpandCollapse(true);
}
super.performRequest(req);
}
