Following code snippet shows how to create Label control in Symbian C++.

== Step 1: LabelTestAppView.h ==

* Open your '''LabelTestAppView.h''' file.<br>
* Inlcude entries for required header files.

<code cpp>
#include <eiklabel.h>
</code>

* Add required functions which will be needed for control.

<code cpp>
TInt CountComponentControls() const;
CCoeControl* ComponentControl(TInt aIndex) const;
void SetText(const TDesC& aText); // To change text(user-inputted)
</code>

* Declare object of Label:

<code cpp>
private: // data
// ..
CEikLabel* iLabel;
</code>

== Step 2: LabelTestAppView.cpp ==

* Open your "LabelTestAppView.cpp" file.

* Now in the '''ContructL()''' function of your '''LabelTestAppView.cpp''' file:

<code cpp>
void CLabelTestAppView::ConstructL( const TRect& aRect )
{
// Create a window for this application view
CreateWindowL();

_LIT(KTextHelloWorld, "hello world");
iLabel = new (ELeave) CEikLabel;
iLabel->SetContainerWindowL( *this );
iLabel->SetTextL(KTextHelloWorld);

// Set the windows size
SetRect( aRect );

// Activate the window, which makes it ready to be drawn
ActivateL();
}

CLabelTestAppView::~CLabelTestAppView()
{
delete iLabel;
}

void CLabelTestAppView::SizeChanged()
{
iLabel->SetExtent( TPoint(0,0), TSize(Rect().Width()/2, Rect().Height()/2));
}

TInt CLabelTestAppView::CountComponentControls() const
{
return 1;
}

CCoeControl* CLabelTestAppView::ComponentControl(TInt aIndex) const
{
switch ( aIndex )
{
case 0:
return iLabel;
default:
return NULL;
}
}

//Call this function to change value of Label
void CLabelTestAppView::SetText(const TDesC& aText)
{
iLabel->SetTextL(aText);
}
</code>

'''Note:''' Do not forget to add an entry for '''eikcoctl.lib''' in your '''.mmp''' file.
