Re: [Dsol-java] Drawing in the Animation Panel

[R.T.H.Chin <r.t...@tb...>]

Hi,

Images in the animation panel usually extend Renderable2D (in the dsol 
project). You should overwrite the abstract paint method in this class 
to draw an image on the animation panel. The only argument of this 
method is a Graphics2D - object, which you can use to draw a line:

graphics.drawLine(x1,y1,x2,y2)

The coordinates are in world coordinates relative to the object's 
location which is represented by the renderable (see the constructor of 
Renderable2D). The coordinates are automatically scaled by the 
Renderable2D before the line is drawn on the animation panel.

See the javadoc of Graphics2D to find out more about drawing images in 
Java2D (just Google for Graphics2D).

Greetings,
Roy
