public:
. . .
static CExampleHelloControl* NewL(const CCoeControl& aContainer,
~CExampleHelloControl();
const TRect& aRect);
private:
void ConstructL(const CCoeControl& aContainer, const TRect&
aRect);
private: // From CCoeControl
void Draw(const TRect&) const;
private:
HBufC* iText;
. . .
};
The essential change here is that I have to pass a CCoeControl& parameter to the control
to tell it which CCoeControl to lodge in.
The construction changes from:
void CHelloGuiAppView::ConstructL(const TRect& aRect)
{
CreateWindowL();
SetRectL(aRect);
ActivateL();
iHelloWorld = iEikonEnv-
>AllocReadResourceL(R_HELLOGUI_TEXT_HELLO);
}
to:
void CExampleHelloControl::ConstructL(const CCoeControl& aContainer,
const TRect& aRect)
{
SetContainerWindowL(aContainer);
SetRect(aRect);
iView=CExampleHelloView::NewL();
iText=iEikonEnv-
>AllocReadResourceL(R_EXAMPLE_TEXT_HELLO_WORLD);
iView->SetTextL(*iText);
. . .
ActivateL();
}
