MacOS Dashboard Widgets

I recently got a Mac and took a look at their dashboard widgets. Such widgets consist of several files:

An HTML file
A CSS file
A JavaScript file
Image files

Of course, I had to try to see how hard it would be to do the same thing in F3. Here's the F3 version of the Calculator widget:

Unfortunately, it's currently impossible to create transparent windows in Java on non-MacOS platforms, so in those cases you won't see the dropshadow and rounded corners.

It only took a few minutes to write the visual elements in F3 (I just used F3Pad). And about another hour to add the behavior (I borrowed the design of the non-visual part of the calculator from an ancient Java applet I found on the net).

F3 Source:

Calculator.f3

Original Source:

Calculator.html

Calculator.css

Calculator.js

Sorry falcon, I'm afraid it's going to be a bit longer. I'm hoping for early March right now (but that's not a promise).

However, I'm 99.5% certain it _will_ be before JavaOne.

I am totally thrilled about this. All these demos seem to have been written in no time. I'd love to be a part of the project that develops this, but I don't know how much use I'd be. Just finishing up a mathematics major / computer science minor at UCFV and hopefully going to grad school in Victoria, BC. Let me know if I can be of service! At any rate, I'll be keeping an eye on F3.

Get yer non-rectangular windows at http://rabbit-hole.blogspot.com. I'll be checking the stuff into jna.dev.java.net when I get the tests finished.

Uh, is there some way to shut off the calculator on Windows without using Task Manager? Thanks, John

Click the F3 icon in the system tray.

Maybe a dumb question but is it possible to get the images referenced in the source? I'd like to try and run the source myself.

Doesn't work at all on my mac, 10.4.9.... An error occurred while launching/running the application. Title: F3 Vendor: Sun Microsystems Category: Launch File Error Unsupported JNLP version in launch file: 1.5+. Only version 1.0 is supported with this version. Please contact the application vendor to report this problem.
