Improving the default Spark skins in Flex 4

April 13th, 2010 Adam 3 comments

I don’t know about everyone else, but I think the default component skins in Flex 4 are a big mistake. Well, let me be clear: I know the new Spark components are now easier to customize. And that is great. I am all for improving customization and usability. But some people don’t like skinning the default components! Would it have been so hard to improve the functionality while still making the default skins pretty? Like the Halo skins from Flex 3? One of the best things about Flex 3 is that I could just pop in a bunch of UI elements and it would be a great-looking application right out of the box. With the addition of Spark, I am now forced to customize the look of the components.

So, for starters, I’ve corrected one of the main faults, which is the font. I found that simply changing the default Spark font, it makes a big impact. All you have to do is add the following style code to your application:

1
2
3
4
5
6
7
<fx:Style>
	@namespace s "library://ns.adobe.com/flex/spark";
	s|Application{
		font-family: "Verdana";
		font-size: 10;
	}
</fx:Style>

As you can see in the example below, the left UI is the default skin. The right UI is with this minor font change. I think it makes a big difference:
(Either JavaScript is not active or you are using an old version of Adobe Flash Player. Please install the newest Flash Player.)

I’m sure there are some other things I can do globally, to make Spark a little better-looking out of the box. The font is just a small step in the right direction.


Another Method

 
Now, I will say that there’s another method of forcing the compiler to use the Halo skins. I don’t like this method though. For starters, the proper skins don’t show up in Design View. Also there are a few syntax issues with mixing the skins. Having said that, if you want to go that route, you can: Go to your project properties, then go to Flex Compiler, and append this text to the Additional compiler arguments:
