TrackbarSetPageSize Function

Overview

The TrackbarSetPageSize function sets the number of logical positions the trackbar's slider moves in response to keyboard page up and page down input.

Syntax/Parameters

Syntax

int = TrackbarSetPageSize ( int id, int size );

Parameters

id

An int containing the control ID of the scrollbar control.

size

An int specifying the page step size in logical units.

Return Value

An int as ERROR_NONE 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

The logical positions are the integer increments in the trackbar's range of minimum to maximum slider positions. The size specifies the larger increment value as the slider is moved with the keyboard.

If the page size is never set, the default value is 1/5th the range.

The trackbar control also sends a scroll notifications with the TRBN_LINEUP and TRBN_LINEDOWN notification codes to its parent window when the user presses the page keys.
