 Posted: Thu Apr 14, 2011 8:31 pm Post subject: Question- Irregularly shaped buttons? |
 |
|
Hello, I'm trying to create a GUI that has some irregularly shaped buttons, and so far I'm failing. I've tried using Jbuttons and replacing the button with an image, unfortunately I end up with a square button large enough to contain my irregular image. Is there a way to set a transparent background color so that when you import the image it knows to treat any pixel that color as "empty"? I've seen that function in another IDE but I'm not sure Java supports it. Is there a better choice than using a Jbutton that would allow me to do what I'm wanting?
More specifically I have a background made up of tessellating shapes and the buttons are shaped to fit into this pattern, but that only works if the button is the right shape, of course  |

The rectangle (border) appears because you haven't told the button not to use it. You also need to tell the button to be transparent. Try some or all of these (can't remember off the top of my head):
JButton.setOpaque(false);
JButton.setBackground(null);
JButton.setBorderPainted(false);
JButton.setBorder(null);
The "clickable region" will still be rectangular, though.

| hrrrm. The clickable area remaining square is less than ideal but at least this gives me a starting point. Thank you! |

The only alternative to the rectangular area is pretty complex.
You'd have to define a 'mask' that exactly matches the shape/size of your
irregular image, then over-ride the mouse listener on the button to test
whether the mouse action occurred over the masked area. If so, proceed with
normal action, if not, bubble the mouse action up to the background
component (ie the componenent on which the button is sitting.).

Hello bro!
if u r using netbeans then simply go to properties window(on right hand side of the netbeans UI) and uncheck the apaque property box.! it will make your button transparent ! |

...and doing that does nothing more than generate the code "buttonName.setOpaque(false);" as my earlier post stated. Not trying to rag on you, but I think it's important that people who want to program in Java actually know the Java way to address a problem. Sadly, the GUI Builder sometimes gets in the way of actually having to learn the language.

Just an idea but how about using the click event on the background image?
It seems like you have to figure out all the mappings of pixels and regions to build the buttons anyway. |

hi,
i agree with Thomas Wolf that , the coding he shares to create a Jbutton transparent i think the coding will be helpful to you to create transparent button , and on the other hand the idea of using the click event on the background image is also a great idea , i appreciate your creativity
