The class of the trackbar control. This is a linear gauge displaying a pointer that indicates some value within a specified range, and allowing users to drag the pointer to other values within the range and thereby effect some arbitrary behavior.
An example use of a trackbar would be the volume slider on a stereo.
Tick marks are displayed at some specified frequency along the trackbar. The trackbar value may also be adjusted using the arrow keys and/or the PAGE UP/PAGE DOWN keys when the trackbar has the keyboard focus, and the amount by which these keys adjust the value can be set.
See About how to get sample code for creating controls in cgide.htm, which explains how to use the IDE to create such code.
