Drawing tool
Mouse events
It has been a long time since last exercises. To fresh up a bit, we will
make a small drawing tool this week.
|
First, create a JFrame that reports the mouse events by System.out.println statements. These events include clicking,
moving, dragging, etc.
Hint: javax.swing.event.MouseInputListener
(since JDK 1.4)
MouseAction.java
|
|
Now extend your JFrame to respond to mouse clicking and dragging by drawing a trail where the cursor is dragged.
The result should be a very simple drawing program.
Paint.java
|
|
Could you imagine some way to save and load your drawings? There are several different ways this could be implemented:
Saving and Image object, image file (GIF, JPEG, etc.) or saving the coordinates of the marked pictures, to mention some.
