Symbian学习笔记14 之 在UI中显示CEikLabel和颜色设置

 这个跟我们在新建HELLOWORLD的UI程序不一样，我们需要在Container中声明个CEikLabel *iLabel成员变量，并把它显示在UI中 。

CEikLabel没有SetColor来设置颜色，它是通过void OverrideColorL(TInt aLogicalColor,TRgb aColor);来设置颜色see:


OverrideColorL()

void OverrideColorL(TInt aLogicalColor,TRgb aColor);

Description

Overrides the control's colour setting, as specified in the application's colour scheme.

This function does not change the application's colour scheme — it changes the colour mapping used in this control only.

Parameters

TInt aLogicalColor	The logical colour. Indicates which part of a control the physical colour maps to. The set of logical colours for a standard application are defined in TLogicalColor.
TRgb aColor	The new physical colour to which the logical colour should be mapped.

void CFirstFuckContainer::ConstructL( const TRect &aRect )
    {
    CreateWindowL();
    InitComponentArrayL();
    iLabel = new (ELeave) CEikLabel;
    iLabel->SetContainerWindowL(*this);
    iLabel->SetRect( aRect );           //一定要加这句,这个用来指定控件所占的区域
    iLabel->OverrideColorL( EColorLabelText, KRgbRed );//设置CEikLabel颜色
    iLabel->SetEmphasis( CEikLabel::ENoEmphasis )
    //iLabel->SetPosition(AKNEXQUERY_LABEL2_POSITION);
    iLabel->SetAlignment( EHCenterVTop );
    iLabel->SetTextL( _L("Billpig"));
    //iLabel->DrawNow();
    
    //Components().AppendLC( iLabel );
    //CleanupStack::Pop( iLabel );
    SetRect( aRect );
    //SetBlank();
    ActivateL();
    }
