Flex application design interface layout is how to achieve, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Focus on how to design the interface layout for Flex applications. Many container components allow you to create layouts in absolute coordinates. You can place components and constrain them according to the relative position of their parent containers, so that they still maintain their positions with each other when the interface of Flex applications is zoomed in or out.

Design the interface layout for Flex applications

Let's take a closer look at the previous simple example of "SayHellotoFlex". You can control the interface layout of the Flex application by setting the property values of the component, as shown below:

Many container components allow layouts to be created in absolute coordinates, which means that you can use precise x and y coordinates to place components. You can also place components and constrain them relative to their parent containers so that they remain in place with each other as the interface of the Flex application zooms in or out.

In this example, the layout property of the panel / Panel component is set to absolute value, while all containers are set to 80% of the size of the application. Two components (TextArea and Button) are placed in specific pixels away from the boundary of the panel container.

Use style and theme to enhance visual design

If the attribute values of the style / style are not specified, they will be controlled by the theme / theme running throughout the program. By default, Flex applications use Halo themes (as in the example above). Of course, you can change the default theme or simply create one yourself. You can also simply specify a new style definition to change the default theme style, like this:

TextArea {font-size:36px; font-weight:bold;}

By explicitly defining a style for the TextArea component, the application now looks like this:

In this example, a new style is defined in the tag in the MXML file. As we mentioned earlier, you can also set new styles by modifying the theme or applying a new theme, using an external CSS file, or setting separate style properties.

To import a style sheet into the MXML file, you need to add the following code:
