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

Step 1: LabelTestAppView.h

• Open your LabelTestAppView.h file.
  
• Include entries for required header files.

#include <eiklabel.h>

• Add required functions which will be needed for control.

TInt CountComponentControls() const;
CCoeControl* ComponentControl(TInt aIndex) const;
void SetTextL(const TDesC& aText); // To change text(user-inputted)

• Declare object of Label:

private: // data
    // ..
        CEikLabel* iLabel;

Step 2: LabelTestAppView.cpp

• Open your "LabelTestAppView.cpp" file.

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

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), iLabel->MinimumSize());
}
 
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::SetTextL(const TDesC& aText)
{
   iLabel->SetTextL(aText);
}

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