Applet displaying an image and letting user select area
Posted on 2002-04-21
I'm creating an applet that's going to display an image on the screen, letting the user select an area, and grabbing the x,y,height,width positions of that area.
The way I am doing it now:
- Using getImage() >> icon >> label >> panel >> container to display the image ..
- I use MouseMotionListener to do a repaint() and then drawRect() when the user drags on the screen.
This will display the image, and let the user select a rectangle.
However, it does not look that good. It's a bit slow, and it flickers. I suppose this is because the repaint() (to draw the image on the screen again, and removing the rectangle) and the drawRect over it to draw the new rectangle.
Any other, better solutions?
