The following example shows how you can control the easing duration and easing functions that the ColorPicker control uses to display its drop-down swatch palette. Of course, this probably isn’t the best example of “useful animation” and will probably just annoy users (the long 2 second easing animation), but it is nice to know that you can change these if you need to.

Here’s a handy little trick, compliments of the ColorUtil class. The ColorUtil class has a couple useful methods if you ever need to change a color’s brightness using either a linear brightness adjustment (ColorUtil.adjustBrightness()) or a scaled brightness adjustment (ColorUtil.adjustBrightness2()). Mind you, I have no idea what that linear brightness versus scaled brightness actually means, so I’ll show both methods side-by-side.

I’ve always hated doing simple date manipulation and having to create wacky variables like “millisecondsPerDay” where you multiply milliseconds by seconds by hours by whatever else. So here’s a useful (and largely untested) function, dateAdd(), which is similar to the function that ColdFusion-ers have enjoyed for years.

In a previous post, “Toggling a Flex container’s visibility”, we looked at toggling a VBox container’s visibility by setting both the visible property and includeInLayout property. While the approach felt a little crude, we can build the same thing using the much more powerful view states. What are view states and how do we use them? Well, if you’re new to states, this should clear everything up: “Adobe - Flex Quick Start Basics: Creating States”.
Now, with that out of the way, lets look at some code and a basic example.
