I  have three images and one line button in left panel and have middle drawing panel where i need to drag and drop images. Every thing is working fine but coming to line button.Here it is drawing lines b/w images.ok fine but here i need to press each and every time i have to press line button in order to draw line b/w images.But my requirement is once line button is pressed then i should able to draw as many lines as possible without selecting each time.
