Thanks Kalpesh for the codes,
But my requirement is somewhat different.
See, I have a canvas. I am creating an UIComponent. Then I am drawing
a
line using uicomp.graphics.linestyle, uicomp.graphics.moveto and
uicomp.graphics.lineto.and adding the uicomp to canvas.
Then I am able to get the the object and clear it also.
But for redrawing using some other color, I need to get the properties
dynamically, for lineto and moveto. By hard coding I am able to do.
{Repeating the question here - Suppose I have drawn a line from
(10,10) to
(100,100), with black color. I want to change it to red. Is there any
way to get the values ie (10,10) and (100,100) dynamically? }
Thanks,
Paritosh
