Overview
This code snippet demonstrates how to add scrollbars to a rich text editor.
This snippet can be self-signed.
Header file
CEikRichTextEditor* iEditor;
CEikScrollBarFrame* iScrollBarFrame;
Source file
// Second phase construction.
void CClientAppView::ConstructL(const TRect& aRect)
{
// Create the rich text editor (iEditor)
// (left out for brevity)
// Create the scrollbar for the editor
iScrollBarFrame = iEditor->CreateScrollBarFrameL();
// Set horizontal scrollbar invisible (EOff) and vertical scrollbar
// visible (EOn)
iScrollBarFrame->SetScrollBarVisibilityL(CEikScrollBarFrame::EOff,
CEikScrollBarFrame::EOn);
}
Note: Scrollbars are not included in the inner region of the editor. This must be taken into account when drawing the editor on the screen:
// Called whenever SetExtent(), SetSize(), SetRect(),
// SetCornerAndSize(), or SetExtentToWholeScreen() is
// called on the control.
void CAppView::SizeChanged()
{
TRect r = Rect();
TInt scrollbarWidth = iEditor->ScrollBarFrame()->
ScrollBarBreadth(CEikScrollBar::EVertical);
TInt editorWidth = r.Width() - scrollbarWidth;
TPoint upperLeftCorner = TPoint(0, 0);
iEditor->SetExtent(upperLeftCorner, TSize(editorWidth, r.Height()));
}
