problems in displaying "text" on the screen after application has started

[Pranoy]

We are developing a calculator on S60 and we having problems in displaying "text" on the screen after application has started. How to do it?
I have pasted my Appview.cpp file below

File: myCalculatorAppView.cpp
#include <barsread.h>  // for resource reader
#include <eiklabel.h>  // for label controls
#include <eikedwin.h>  // for CEikEdwin
#include <coemain.h>
#include <myCalculator.rsg>
#include <gulcolor.h>
#include "myCalculatorAppView.h"

_LIT(KLabelTextA,"hello, this is it.");

// Standard construction sequence
CmyCalculatorAppView* CmyCalculatorAppView::NewL(const TRect& aRect)
    {
    CmyCalculatorAppView* self = CmyCalculatorAppView::NewLC(aRect);
    CleanupStack::Pop(self);
    return self;
    }

CmyCalculatorAppView* CmyCalculatorAppView::NewLC(const TRect& aRect)
    {
    CmyCalculatorAppView* self = new (ELeave) CmyCalculatorAppView;
    CleanupStack::PushL(self);
    self->ConstructL(aRect);
    return self;
    }

CmyCalculatorAppView::CmyCalculatorAppView()
					:iLabelAA(NULL)
    {
	// no implementation required
    }

CmyCalculatorAppView::~CmyCalculatorAppView()
    {
        delete iLabelAA;
    }

void CmyCalculatorAppView::ConstructL(const TRect& aRect)
    {
    // Create a window for this application view
    CreateWindowL();
    CEikLabel* iLabelAA;
    iLabelAA = new (ELeave) CEikLabel;
    iLabelAA->SetContainerWindowL(*this);
    iLabelAA->SetTextL(KLabelTextA);
    iLabelAA->OverrideColorL( EColorLabelTextEmphasis, KRgbRed );
iLabelAA->SetEmphasis( CEikLabel::EPartialEmphasis );  
    iLabelAA->SetExtent( TPoint(10,10), iLabelAA->MinimumSize() );
    // Set the windows size
    SetRect(aRect);

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

// Draw this application's view to the screen
void CmyCalculatorAppView::Draw(const TRect& aRect) const
    {
    // Get the standard graphics context 
    CWindowGc& gc = SystemGc();
    
    // Gets the control's extent
    TRect rect = Rect();
    
    // Clears the screen
    gc.Clear(rect);
    gc.DrawRect(aRect);
    }

you should also implement CountComponentControls() & ComponentControl() functions so the system would know to draw your label.

Thanks.

Is there somthing like a tutorial that we may follow. just like this problem, sometimes we just don't know which things should be defined in order to make the whole application work, as for our beginners.

You could maybe check the helloworld example fshipped with the SDK, If I remember right it is using Labels in container, thus would show all required stuff in it.
