添加控件的方法,该如何处理

添加控件的方法
请问各位高手，如何在CodeWarrier中添加控件？
有没有什么简单的方法？
不能像在VC下那样拖控件吗？
注：（最好能有源码，小弟刚学不久）

[解决办法]
class CxxxContainer : public CCoeControl
{
public: // Constructors and destructor
void ConstructL(const TRect& aRect);
~CxxxContainer();
private: // Functions from base classes
void SizeChanged();
TInt CountComponentControls() const;
CCoeControl* ComponentControl(TInt aIndex) const;
void Draw(const TRect& aRect) const;
TKeyResponse OfferKeyEventL( const TKeyEvent& aKeyEvent, TEventCode aType );
public:
CEikEdwin *iEditor;
};

void CxxxContainer::ConstructL(const TRect& aRect)
{
CreateWindowL();
iEditor = new (ELeave) CEikEdwin;//添加
iEditor-> ConstructL(...); //添加

ActivateL();
}

CxxxContainer::~CxxxContainer()
{
delete iEditor; //添加
}

void CxxxContainer::SizeChanged()
{
iEditor-> SetRect(Rect());//添加
}

TInt CxxxContainer::CountComponentControls() const
{
return 1; //添加
}

CCoeControl* CxxxContainer::ComponentControl(TInt aIndex) const
{
switch ( aIndex )
{
case 0:
return iEditor;//添加
default:
return NULL;
}
}


void CxxxContainer::Draw(const TRect& aRect) const
{
...
}

TKeyResponse CxxxContainer::OfferKeyEventL( const TKeyEvent& aKeyEvent, TEventCode aType ){
return iEditor-> OfferKeyEventL( aKeyEvent, aType );//添加

}
