The CSkinnedContainer implementation illustrates how to draw skins in a CCoeControl derived container in the S60 platform.

The iBgContext is the CAknsBasicBackgroundControlContext which is used to draw the skin on the control's background. To draw on a different screen area you could change KAknsIIDQsnBgScreen identify to the background you would like to use with your container.

Note that for the skins to work properly you need to enable skins first. Usually this is done in Application user interface class' ConstructL() method by calling the ConstructL() method with CAknAppUi::EAknEnableSkin parameter.

SkinnedContainer.cpp

CSkinnedContainer::~CSkinnedContainer()
{
delete iBgContext;
iBgContext = NULL;
}
 
CSkinnedContainer* CSkinnedContainer::NewL(void)
{
CSkinnedContainer* self = new(ELeave)CSkinnedContainer();
CleanupStack::PushL(self);
self->ConstructL();
CleanupStack::Pop(self);
return self;
}
 
void CSkinnedContainer::ConstructL(void)
{
CreateWindowL();
 
// make first with no size at all
iBgContext = CAknsBasicBackgroundControlContext::NewL(
KAknsIIDQsnBgScreen,TRect(0,0,1,1), ETrue);
// Setting rect will cause SizeChanged to be called
// and iBgContext size & position is updated accordingly.
SetRect(CEikonEnv::Static()->EikAppUi()->ClientRect());
 
ActivateL();
DrawNow();
}
 
void CSkinnedContainer::SizeChanged()
{
if ( iBgContext )
{
iBgContext->SetRect(Rect());
 
if ( &Window() )
{
iBgContext->SetParentPos( PositionRelativeToScreen() );
}
}
}
 
 
void CSkinnedContainer::HandleResourceChange(TInt aType)
{
TRect rect;
 
if ( aType==KEikDynamicLayoutVariantSwitch )
{
AknLayoutUtils::LayoutMetricsRect(AknLayoutUtils::EMainPane, rect);
SetRect(rect);
}
 
CCoeControl::HandleResourceChange(aType);
}
 
 
TTypeUid::Ptr CSkinnedContainer::MopSupplyObject(TTypeUid aId)
{
if (iBgContext)
{
return MAknsControlContext::SupplyMopObject(aId, iBgContext );
}
 
return CCoeControl::MopSupplyObject(aId);
}
 
 
void CSkinnedContainer::Draw(const TRect& aRect) const
{
CWindowGc& gc = SystemGc();
 
// draw background skin first.
MAknsSkinInstance* skin = AknsUtils::SkinInstance();
AknsDrawUtils::Background( skin, iBgContext, this, gc, aRect );
}
