Hi all, I'm struggling here, for what is something that I know should be very simple. I want to draw a small circle on a form, and change it's colour. I've looked at the help, seen and tried some examples, attempted to take from these what I need and failed, repeatedly. Does somebody have a really simple example of this I can steal? Thanks lots, Jason

GUI Fun! Not enough posts here are about just plain fun stuff to do with AutoIt, at least not lately. So I figure, why not dig up one of my old UDFs, clean it up a bit, and throw it very emphatically at you lot of misfits! One way of mucking about with AutoIt and Windows that can be entertaining is creating shaped GUIs. Sure, GUIs with regions are nothing new here or in general on the Windows platform. But have you ever just wanted to stare at colorful shapes flying across your screen, for no apparent reason? Well, my friend, you've come to the right place. The first UDF I've put up pretty simple. Boxes, circles, triangles, diamonds, and stars are what I bring you, in technicolor wonder. I will probably add a few more examples when I find the time.. However, its my hope that more people add to this thread - and maybe provide links to other topics or posts where some nifty GUI fun is to be had!

These GUI's have no interactive elements or controls and are click-through-able, meaning that a click on the GUI will pass through to whatever window is underneath. _LineTraverser is a UDF with functions to create a well, line traverser. Given a start and end point, it will allow you to step through a given line without needing to do any extra work on your behalf. This uses Bresenham's line algorithm to calculate the individual steps. I know this one isn't related to GUI, but its what I used for my second 'GUI fun' example below. Pacman Line-Traversing GUI (>static or >animated). That's right, I managed to animate a GUI! Check it! (now included in the ZIP) Examples that follow will be bundled with the ZIP. Have fun!
