Flex mobile as cross platform mobile development tool.

Meanwhile I don't understand how to place evenly controls and occupate all available space. I see at emulator controls don't occupy available space.

Trying to port some WPF XAML. To make possible to write at *.mxml files some kind of XAML markup.
1. In order to see your object in mxml markup its class should extend Object.
2. Why Intellij Idea doesn't have context help by Flex objects?
3. Flex Reflection
4. Flex mxml app architecture
