Overview
The TrackbarGetPageSize function returns the ‘page’ size for trackbar slider movement when the page up and page down keys are used for positioning.
Syntax/Parameters
Syntax
int = TrackbarGetPageSize ( int id );
Parameters
id
An int containing the control ID of a trackbar control.
Return Value
An int as the logical page step count or a formatted error code on failure. Common errors include: ERROR_RANGE if id is an invalid control ID for the open dialog or ERROR_INVALID_HANDLE if no dialog is open.
Remarks
This function retrieves the number of logical positions the trackbar's slider moves in response to keyboard input from the page keys. The logical positions are the integer increments in the trackbar's range of minimum to maximum slider positions.
If the page size is not set, the default page size is 1/5th of the range value.
