Overview
This snippet demonstrates how to move the scrollbar thumb to a certain position. This is useful, for example, after an external scroll (such as a scroll caused by program code).
This snippet can be self-signed.
MMP file
The following libraries are required:
LIBRARY eikcoctl.lib
Header file
#include <eiksbfrm.h> // CEikScrollBarFrame
#include <eikscrlb.h> // TAknDoubleSpanScrollBarModel
CEikScrollBarFrame* iScrollBarFrame;
TAknDoubleSpanScrollBarModel iVModel;
Source file
The following code updates the scrollbar model and moves the vertical scrollbar thumb to a position specified by the model. The code could be written in CMyContainer::OfferKeyEventL(), for example.
// Update the model. Naturally, number 10 would be calculated, not specified
// as a magic number constant.
iVModel.SetFocusPosition(10);
// Move the scrollbar thumb to model position
iScrollBarFrame->SetVFocusPosToThumbPos(iVModel.FocusPosition());
Postconditions
The thumb of the vertical scrollbar moves to the position specified by the scrollbar model.
