Field descriptions

viewsize

A signed 32-bit integer, specifying the size of the content being displayed. This value should be expressed in terms of the same units of measurement as are used for the minimum, maximum, and current settings of the scroll bar.

pressState

A value of type ThemeTrackPressState, specifying what in the scroll bar is currently pressed. See “Theme Track Press State Constants” for descriptions of possible values. Pass 0 if nothing is currently pressed.

Your application uses the ScrollBarTrackInfo structure in the ThemeTrackDrawInfo structure to describe the scroll bar–specific features of a given track control.

VERSION NOTES

The ScrollBarTrackInfo structure is available with Appearance Manager 1.1 and later.
