’CExtTabPageContainerOneNoteWnd’ has a strong background color which is behind the tabs. This color mostly does not fit in the layout of the application. How can I change/disable this background? I have allready my own class derived from ’CExtTabPageContainerOneNoteWnd’. If you wish I send you pictures of relating sector. Thanks!

Yes, some screenshots would be greatly appreciated. We assume you want to replace a vertical gradient background with a horizontal one. In this case, just use a CExtTabPageContainerOneNoteWnd derived class like as follows:class CMyTabPageContainerOneNoteWnd : public CExtTabPageContainerOneNoteWnd
{
class CMyTabOneNoteWnd : public CExtTabOneNoteWnd
{
public:
void OnTabWndEraseClientArea(
CDC & dc,
CRect & rcClient,
CRect & rcTabItemsArea,
CRect & rcTabNearBorderArea,
DWORD dwOrientation,
bool bGroupedMode
)
{
ASSERT_VALID( this );
ASSERT( dc.GetSafeHdc() != NULL );
rcTabItemsArea;
bGroupedMode;
g_PaintManager->PaintTabClientArea(
dc,
rcClient,
rcTabItemsArea,
rcTabNearBorderArea,
dwOrientation,
bGroupedMode,
this
);
if( ! rcTabNearBorderArea.IsRectEmpty() )
{
// prepare tab border margin rect
CRect rcTabNearMargin( rcTabNearBorderArea );
CRect rcColorLine( rcClient );
switch( dwOrientation )
{
case __ETWS_ORIENT_TOP:
rcTabNearMargin.bottom = rcTabNearMargin.top + 1;
rcTabNearMargin.OffsetRect(0,-1);
rcColorLine.top = rcTabNearMargin.bottom;
break;
case __ETWS_ORIENT_BOTTOM:
rcTabNearMargin.top = rcTabNearMargin.bottom - 1;
rcTabNearMargin.OffsetRect(0,1);
rcColorLine.bottom = rcTabNearMargin.top;
break;
case __ETWS_ORIENT_LEFT:
rcTabNearMargin.right = rcTabNearMargin.left + 1;
rcTabNearMargin.OffsetRect(-1,0);
rcColorLine.left = rcTabNearMargin.right;
break;
case __ETWS_ORIENT_RIGHT:
rcTabNearMargin.left = rcTabNearMargin.right - 1;
rcTabNearMargin.OffsetRect(1,0);
rcColorLine.right = rcTabNearMargin.left;
break;
default:
ASSERT( FALSE );
break;
} // switch( dwOrientation )
// paint tab border margin
dc.FillSolidRect(
&rcTabNearMargin,
g_PaintManager->GetColor( COLOR_3DSHADOW, this )
);
if( dc.GetDeviceCaps( BITSPIXEL ) > 8 )
{
COLORREF clrBkDark;
OnTabWndQueryItemColors(
SelectionGet(),
false,
false,
NULL,
NULL,
NULL,
&clrBkDark,
NULL
);
dc.FillSolidRect(
&rcColorLine,
clrBkDark
);
}
else
{
dc.FillSolidRect(
&rcColorLine,
g_PaintManager->GetColor(
SelectionGet() >= 0
? COLOR_WINDOW
: COLOR_3DFACE
,
this
)
);
}
} // if( ! rcTabNearBorderArea.IsRectEmpty() )
}
};
public:
virtual CExtTabWnd * OnTabWndGetTabImpl()
{
return new CExtTWPC < CMyTabOneNoteWnd >;
}
};CExtTabPageContainerOneNoteWnd::PageInsert() method, find the following lines:CExtTabOneNoteWnd * pWndTab =
dynamic_cast < CExtTabOneNoteWnd * > ( m_pWndTab );CExtTabOneNoteWnd * pWndTab =
DYNAMIC_DOWNCAST( CExtTabOneNoteWnd, m_pWndTab );
