I had a bit of time over the weekend so I thought I’d work on a few more examples for http://blog.flexexamples.com.

Nothing really advanced, but a couple neat tricks in there (hopefully). Enjoy,

• Adjusting a color’s brightness using the ColorUtil class
• Changing the ColorPicker control’s easing duration and easing functions
• Changing a CheckBox control’s icon color and border color
• Changing a CheckBox control’s label placement
• Changing a Tile container’s horizontal and vertical alignment
• Changing a Tile container’s horizontal and vertical gaps
• Changing a Tile container’s child layout direction
• Using the ZipCodeValidator class to validate US or Canadian zip codes
• Using the CurrencyValidator and CurrencyFormatter classes to validate and format numbers
• Enabling and disabling specific tabs in a TabBar control
• Docking an ApplicationControlBar container
• Changing a CheckBox control’s icon
• Changing a Button control’s text alignment and label placement
• Changing a Button control’s text color

A bit of a “short” list this week as I posted last Sunday instead of Friday. I posted the following examples over on my other blog, blog.flexexamples.com, the past week. Next week I hope to have a few examples on using the excellent Flex Component Kit for Flash CS3, which allows you to create assets in Flash CS3, export them as a SWC file, and use those assets in Flex. For more information, check out the entry “Using the Flex Component Kit for Flash CS3 to Create Flex Containers” on the Flex documentation team’s blog.

Happy Flexing!
