Hi, I need to draw different kind of 2d figures on a JPanel, and once drawed I would like to be able to select one of them and modify its size, at this moment I'm just using the paintComponent() method, and every time I make a change I practically have to draw Again all figures, but I was thinking it maybe is possible to do it using the drag and drop features, I have never used it but a friend of mine told me that it maybe it could to make easier to develop.

Any has a goo idea how to solve this??
