Example #1

File: 3DList.cpp Project: sanyaade-webdev/wpub

void C3DList::OnLButtonDown(UINT nFlags, CPoint point) 
{
	SetCapture();

	RECT rect, hs, vs;
	GetClientRect( &rect );

	m_scrollbar.GetClientRect( &vs );
	rect.right -= RW( vs );

	// If horizontal scroll bar
	if ( !GetListCtrl().GetHeader().IsAutosizing() )
	{
		m_hscroll.GetClientRect( &hs );
		rect.bottom -= RH( hs );

		rect.bottom -= GetSystemMetrics( SM_CYHSCROLL );
		RedrawWindow( &rect );
		UpdateVScrollBar();
	} // end if
	
	CStatic::OnLButtonDown(nFlags, point);
}

Example #2

File: 3DList.cpp Project: sanyaade-webdev/wpub

void C3DList::OnPaint() 
{
	CPaintDC dc(this); // device context for painting

	UpdateVScrollBar();
	UpdateHScrollBar();

			m_hscroll.ShowWindow( SW_SHOWNORMAL );

			// Validate hscroll
			ValidateRect( &rect );

		} // end if
		else m_hscroll.ShowWindow( SW_HIDE );

		
	} // end if

	RedrawWindow();
}
