Dear Support,

I have a CScrollView derived class, and it appears with the XP native scroll-bars.
How can I make the scroll bars be Prof-UIS themed?

Thanks,
Ron.

You can learn more about themed scrollbars if you look at this sample.

Dear Suhai & Support,

I used your project to skin my scroll-view scroll bars, thanks.
However, there is one problem - the square at the right-bottom side of the view, is not being drawn correctly - it is left with some garbage.
You can see it also in the sample application you referred me to.

How can this be fixed?

Thanks,
Ron.

Dear Suhai & Support,

I think the scroll-bar theme should be an integral part of Prof-UIS.
Some kind of templating that adds the scroll-bar themes should be provided.

Regards,
Ron.

We answered a similar question in this forum thread. You can also see an example of themed scroll bars in the DrawCli sample (the CDrawView class).

Dear Support,

I tried to do exactly what is done in the suggested thread, and no scroll-bars appear.
I tried what Suhai suggested, and it worked - All I did is add this line:

SkinWndScroll(this);

My only problem is the right-bottom square that is not redrawn correctly.

How can this be fixed?

Thanks,
Ron.

This area should be painted manually by your scroll view window. This problem is solved in our CExtScrollWnd class (see the OnSwPaintAreaBetweenScrollBarWindows() method).

Dear Support,

I am using CSkinScrollWnd, so I updated the empty OnPaint with this code:

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

	if (m_sbHorz.IsWindowVisible() && m_sbVert.IsWindowVisible())
	{
		CRect rcH, rcV;
		m_sbHorz.GetWindowRect(rcH);
		m_sbVert.GetWindowRect(rcV);
		ScreenToClient( &rcH );
		ScreenToClient( &rcV );
		CRect rcAreaBetweenScrollBarWindows;
		rcAreaBetweenScrollBarWindows.SetRect( rcV.left, rcH.top, rcV.right, rcH.bottom );

		dc.FillSolidRect(
			&rcAreaBetweenScrollBarWindows,
			g_PaintManager->GetColor( COLOR_3DFACE )
			);
	}
}

And it works.

Regards,
Ron.

The ::IsWindowVisible( hWnd ) code returns TRUE if the hWnd window has the WS_VISIBLE style and if it is not covered completely by any other window, i.e. if it is really visible on the screen. This API is not applicable in the code snippet listed in your message. You should simply check for the presence of the WS_VISIBLE style instead. So you should replace

      if( m_sbHorz.IsWindowVisible() && m_sbVert.IsWindowVisible() )

with

      if( (m_sbHorz.GetStyle()&WS_VISIBLE) != 0 && (m_sbVert.GetStyle()&WS_VISIBLE) != 0 )
