Animation Control (MSAA UI Element Reference)
Animation controls silently display an audio video interleaved (AVI) clip. Animation controls are usually displayed when files are being copied or when some other time-consuming task is being performed.
The window class name for an animation control is ANIMATE_CLASS, which is defined as "SysAnimate32" in Commctrl.h.
IAccessible Methods
Animation controls support the following IAccessible methods:
IAccessible Properties
Animation controls support the following IAccessible properties:
| Property | Comments |
|---|---|
| get_accChildCount | The ChildCount property is zero. |
| get_accKeyboardShortcut | Animation controls do not have keyboard shortcuts. However, if the label for the control contains an access key (an underlined character in the text of the control's label), get_accKeyboardShortcut returns a non-NULL string. This string contains the access key character appended to the string "Alt+". For example, if the label is "Downloading Files", KeyboardShortcut is "Alt+d". |
| get_accName | The Name property is obtained from the static text control that labels the animation control. When creating controls, server developers must ensure that a static text control immediately precedes the control that it labels within the tab order. |
| get_accParent | The Parent property is a window ( ROLE_SYSTEM_WINDOW ) that surrounds the control and has the same Name property and window class name as the control. |
| get_accRole | The Role property is ROLE_SYSTEM_ANIMATION. |
| get_accState | The State property is a combination of one or more of the following object state constants: STATE_SYSTEM_INVISIBLE | STATE_SYSTEM_UNAVAILABLE | STATE_SYSTEM_FOCUSED | STATE_SYSTEM_ANIMATED For more information, see Object State Constants. |
