    Question Help me to draw line and rectangle

    Hi,

    I want to draw line and rectangle in my application. I am getting error undefined identifier 'gc'. I know undefined identifier means it is not defined.but it is defined in view class.
    My code is here for drawing line and rectangle..

    case EGUICmdLine:
    { // to draw Line
    TPoint startPoint(50,50);
    TPoint endPoint(590,190);
    gc.DrawLine(startPoint,endPoint);
    break;
    }

    case EGUICmdRect:
    {

    // To draw rectangle
    gc.SetBrushColor( TRgb(255,0,0));
    gc.SetBrushStyle( CGraphicsContext::ESolidBrush );
    TRect drawRect(15,15,50,50);
    gc.DrawRect(drawRect);
    }
    In my view class I have this line. CWindowGc& gc = SystemGc();

    Please tell me which mistake I am doing. I need help so please any one answer me or correct my code so I can use.
    I am waiting for valuable response.

    CWindowGc& gc = SystemGc();
    I think you have spezified this in your draw() Funktion??

    Is your drawing code in the same Funktion?

    Hi,
    Thanks for qucik reply,

    It is specified in Draw() function of view class. My drawing code is in AppUI class. Please if you give little bit more details then I can solve my problem.

    Re: Help me to draw line and rectangle

    Just make your drawings in the view. Thats what the draw() funktion is made for.

    If you initialize your CWindowGc& lokaly in your Draw() Funktion of the view, the AppUi is not able to know this!
