Scroll bar problem Nokia 5800

[aamitgupta]

Hi All,

I create a GUI that have scroll bar in container, but the scroll bar is not scrolled or my text which i draw on screen display only 11 line text rest all text does not display, but in my next screen i draw a list here the scroll bar is working fine.

My code is following
in constructl function:

iDeviceMap = iCoeEnv->ScreenDevice();
	iNum=2;	// This Number handle scroll down and up counting
	iScrollBarFrame = new(ELeave) CEikScrollBarFrame(this, this,ETrue);
	iScrollBarFrame->SetScrollBarVisibilityL(CEikScrollBarFrame::EOff, CEikScrollBarFrame::EAuto);
	iScrollBarFrame->CreateDoubleSpanScrollBarsL(ETrue,EFalse);
	TRect rect = Rect();
	rect.iTl.iX=Rect().iBr.iX-iScrollBarFrame->VerticalScrollBar()->DefaultScrollBarBreadth();
	
	iDoubleSpanAttributes.iScrollSpan = iNum;
	iDoubleSpanAttributes.iThumbSpan = 1;
	iDoubleSpanAttributes.iThumbPosition = iCurrentScrollNum;
	
	iScrollBarFrame->Tile(&iDoubleSpanAttributes,rect);
	iScrollBarFrame->MoveVertThumbTo(iDoubleSpanAttributes.iThumbPosition);
	iScrollBarFrame->DrawScrollBarsNow();

TKeyResponse CMyViewContainer::OfferKeyEventL(const TKeyEvent& aKeyEvent,TEventCode aType)
{
	if (aType != EEventKey)
		{
		return EKeyWasNotConsumed;
		}

//	if ((aKeyEvent.iCode == EKeyDownArrow) || (aKeyEvent.iCode == EKeyUpArrow))
	if ((aKeyEvent.iCode == EStdKeyDownArrow) || (aKeyEvent.iCode == EStdKeyUpArrow))
		{
		//if (aKeyEvent.iCode == EEventKeyDown)
		if (aKeyEvent.iCode == EStdKeyDownArrow)
			{
			if (iCurrentScrollNum < iNum - 1)
				{
				iCurrentScrollNum++;
				}
			}
		//else if (aKeyEvent.iCode == EEventKeyUp)
		else if (aKeyEvent.iCode == EStdKeyUpArrow)
			{
			if (iCurrentScrollNum > 0)
				{
				iCurrentScrollNum--;
				}
			}

		iVertModel.iThumbPosition = iCurrentScrollNum;
		DrawNow();
		iScrollBarFrame->SetVFocusPosToThumbPos(iVertModel.iThumbPosition);	
		iScrollBarFrame->DrawScrollBarsNow();
		return EKeyWasConsumed;
		}			
		
	return EKeyWasNotConsumed;
	}

please any body help me, i m serching a scroll bar example in S60 5th edition.

In 5th edition you should be handling scroll events in HandlePointerEventL right? The code you have posted is for OfferKeyEventL. Just check if at all it is getting executed. If its N97 then it might be ok as keyboard is there.

The scroll bar is working now but the problem is i am drawing some texts in the container line by line like following.

these text writes in a the loop, in the container it draws only 11 lines, rest all lines does not visible.

    	
	// Clear the graphics context.
	CWindowGc& gc = SystemGc();
	//gc.Clear(); 
/* 	
    gc.SetPenStyle( CGraphicsContext::ENullPen );
    gc.SetBrushColor( KRgbWhite );
    gc.SetBrushStyle( CGraphicsContext::ESolidBrush );
    gc.DrawRect( aRect );

	//skin
	TRgb textColor; // text color when not highlighted
	MAknsSkinInstance* skin =AknsUtils::SkinInstance();
	AknsUtils::GetCachedColor( skin, textColor, KAknsIIDQsnTextColors, EAknsCIQsnTextColorsCG9 );

    TRealFormat y(6,2);
    y.iType=KRealFormatFixed;
	//gc.SetPenColor(KRgbWhite);
    gc.SetPenColor(textColor);
	TBuf<32> fontName=_L("LatinPlain12");
    CFont* fontToUse;	
	CGraphicsDevice* iDeviceMap = iCoeEnv->ScreenDevice();
    TInt iHeightTwips = 100;
    
    #ifdef __SERIES60_30__

		iHeightPixels=12;
		iHeightTwips = iDeviceMap->VerticalPixelsToTwips(iHeightPixels);

	#endif
		
		
	TPoint textPoint(10, 5);
	TInt l2 = 8; 
	TFontSpec fontSpec(fontName, iHeightTwips);
	iDeviceMap->GetNearestFontInTwips(fontToUse, fontSpec);
	gc.UseFont(fontToUse);
	
	
	for (TInt i = iCurrentScrollNum+1; i < iCurrentScrollNum+12; i++)
    { 
		if(i <= 14)
		{

			textPoint.iY += (fontToUse->HeightInPixels() + 5);
			gc.DiscardFont();
			iDeviceMap->ReleaseFont(fontToUse);	    
			#ifdef __SERIES60_30__
		     	fontName=_L("Latin");
		 		TFontSpec fontSpec1(fontName, iHeightTwips);
		 		fontSpec1.iFontStyle.SetStrokeWeight(EStrokeWeightBold);
		    #else
		    	fontName=_L("LatinBold12");
		 		TFontSpec fontSpec1(fontName, iHeightTwips);
		    #endif	
			iDeviceMap->GetNearestFontInTwips(fontToUse, fontSpec1);
			gc.UseFont(fontToUse);
		    TInt k=i;
			gc.DrawText(formattedLabel[k], textPoint);
		}  // end of if 
     	    
	 }//for loop closed
	gc.DiscardFont();
  	iDeviceMap->ReleaseFont(fontToUse);

In the formattedLabel[] array has the string value which draws.

so is it that you need to use scroll bar to loop thru next 11 set of lines.
