This parameter is ignored. No animation can be played when the control is made invisible.

Duration of animation in hundredths of a second. This parameter can correspond to:

• an integer corresponding to the number of hundredths of a second,
• a Duration variable,
• the duration in a readable format (e.g., '1cs' or '10 ms').

We recommend that you use a short duration (up to 1 second).
The application is locked as long as the animation is not over. If the user clicks or preses a key, the animation is stopped and the controls are displayed in their final status.
