Custom Shape Buttons

Buttons of Irregular Shape

In previous post, I have demonstrated how to detect mouse click in a triangular region. That made implementation of a triangular button possible. In this post I will move one step forward. I am going to implement a button with arbitrary shape.

Transparent Image

First you will need a transparent image file to act as the button. It is not difficult to make one yourself. I have prepared one for you:

Download it and save it as "a.png". Place it at the same folder as ImageButton.java.


The actual code is simple, we will simulate a button using a JLabel. We will attach a image to the JLabel, then capture the mouse event, and ignore the mouse click if it click on a transparent pixel.
