Using Theme in an Application

Using Theme in an Application

This article can tell you how to write a enable skins application.

You can use theme in an Application after version in Series 60 Platform 2.0. the following content will tell you how to do these step by step.

Link against aknskins.lib and include files

Add the libray named aknskins.lib in SkinSample.mmp

Code:

LIBRARY aknskins.lib // link against aknskins.lib

Add two include files in SkinExampleContainer.h

Code:

#include <AknsDrawUtils.h>// add this inlcude file skin
#include <AknsBasicBackgroundControlContext.h> //add this inlcude file skin

Enabling skins in AppUi

Code:

/* In SkinExampleAppUi.cpp */

void CSkinExampleAppUi::ConstructL()
{
BaseConstructL( EAknEnableSkin );//Construct a enalbe skin

.....

}

new and delete a MAknsControlContext class in Container class

Add a MAknsControlContext class in container class

Code:

/* In skinExampleContainer.h */

class CSkinExampleContainer : public CCoeControl, MCoeControlObserver

{

....

private:

MAknsControlContext* iBackGround; // for skins support

}

/* In SkinExapleContainer.cpp */

void CSkinExampleContainer::ConstructL(const TRect& aRect)
{
CreateWindowL();

    iLabel = new (ELeave) CEikLabel;
    iLabel->SetContainerWindowL( *this );
    iLabel->SetTextL( _L("Skin Example") );

SetRect(aRect);
iBackGround = CAknsBasicBackgroundControlContext::NewL( KAknsIIDQsnBgAreaMain, Rect(), EFalse );// new a background

ActivateL();
}

Delete iBackGroud

Code:

// Destructor
CSkinExampleContainer::~CSkinExampleContainer()
{
.....

delete iBackGround;
}

Draw the background bitmap using Skin library

Code:

/* In SkinExapleContainer.cpp */

void CSkinExampleContainer::Draw(const TRect& aRect) const
    {
    CWindowGc& gc = SystemGc();
// draw background
MAknsSkinInstance* skin = AknsUtils::SkinInstance();//new
MAknsControlContext* cc = AknsDrawUtils::ControlContext( this );//new
    AknsDrawUtils::Background( skin, cc, this, gc, aRect );//new
    }

MObjectProvider Chains

MObjectProvider interface can be used to make object instances available to child controls.

MopSupplyObject returns a pointer based on the given UID.

Code:

/* In SkinExapleContainer.cpp */

TTypeUid::Ptr CSkinExampleContainer::MopSupplyObject(TTypeUid aId)
    {
    if(aId.iUid == MAknsControlContext::ETypeId && iBackGround)
        {
        return MAknsControlContext::SupplyMopObject( aId, iBackGround);
        }

return CCoeControl::MopSupplyObject( aId );
}
