Theme Parts and States (Windows Embedded CE 6.0)

1/6/2010

Controls and windows that are drawn by Windows Embedded CE are divided into parent and child parts. Most parts have a state: for example, disabled, active, or selected. When you create a control, you decide which parts of the control to apply visual styles to. You divide the control into a main (parent) part and zero or more named child parts. Examples of parts are text areas, drawn shapes, images, and lines. For each part, you can define one or more background images in a single bitmap file. The different backgrounds are usually associated with different states of the control, but do not have to be. For example, if the control is disabled, a dimmed background might be used. At run time, the appropriate image can be selected by using an integer value that identifies the state of the part. This state identity value is defined as a 1-based index to the correct image.

The following tables show the controls that support visual styles in Windows Embedded CE, the control parts, and their associated state identification.
