Description

MarqueeSpeed is a Cardinal property which sets the update interval for the progress bar. It specifies, in milliseconds, often a progress bar using the marquee display style is updated. The default value for the property is 0.

Changing the value for the property causes a TDM_SET_PROGRESS_BAR_RANGE message to be sent using the Handle for the task dialog. It allows the widgetset class to be notified when the marquee progress bar style is enabled, or when its update interval has been changed. The update is sent when tfShowMarqueeProgressBar has been included in the Flags for the task dialog and its Handle has been assigned.

Version info

Added in LCL version 4.0.
