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.
