Does Flex allow full control over UI components?

I'm wondering what the best tool is for developing a mobile UI is. My requirements are that I retain full control over the look and movement of every UI component. I think Flex might be the best way to do this but I can't tell if I'll have that level of control using their UI components.

Any links would be appreciated. Thanks!

Edit: For example, looking at the documentation I see there's a an 'enabled' field which dims the color of a container and it's children if false. Am I able to change that so, maybe a repeated bitmap pattern appears if false?

Or, if there's a sliding menu can I edit the speed开发者_开发百科 and change in speed as it closes?

You can create any component you like and make it look like anything you want. You don't have to use standard components. You can reskin any components just by specifying a new skin. It's really pretty easy.

You can create custom skins for Flex, for both Spark and Halo components. You also can create custom components, either based on other existing components, or based on the base component. You could even create custom objects which are just based on Sprites or similar (if you like to have control over everything :P).

In response to your updated question. Regarding the enabled/disabled property, yes, it is possible to skin that. Spark components have states, for example a Button has a up, over and down state – and an disabled state. That state is exactly what is active when the enabled property is set to false. So yes, you can skin that.

Regarding the sliding menu animation, I'm not totally sure if that would be easily possible as I believe that this is coded into the component itself and not part of the skin to decide. However even if that is the case, you could instead create your own component that basically features exactly the same functionality but has a changed animation there.

I'm not sure if the Spark skinning wouldn't be able to do this though, because what you definitely can do is creating transitions between states. So if the slide is made with different states, you'll probably be able to change the transition as well.
