Symbian 中各种提示、输入对话框的使用

核心提示：iCoeEnv->CreateResourceReaderLC( reader, R_RESOURCE_EDITOR ); //从资源文件构造编辑框，资源见下面的定义iGKeyEd = new ( ELeave ) CEikGlobalTextEditor;iGKeyEd->SetContainerWind

iCoeEnv->CreateResourceReaderLC( reader, R_RESOURCE_EDITOR ); //从资源文件构造编辑框，资源见下面的定义

iGKeyEd = new ( ELeave ) CEikGlobalTextEditor;

iGKeyEd->SetContainerWindowL( *this );

iGKeyEd->ConstructFromResourceL( reader );

CleanupStack::PopAndDestroy(); // Resource reader

//设置编辑框的初始文本和位置，编辑框大小在资源中定义

TBuf<32> buf;

buf.Copy(_L("demo"));

iGKeyEd->SetTextL(&buf);

iGKeyEd->SetExtent( TPoint(5,2), iGKeyEd->MinimumSize() );

iGKeyEd->SetFocus(ETrue);

// iGKeyEd->SetReadOnly(ETrue); //设置编辑框为只读

//使文字居中

CParaFormat paraFormat;

TParaFormatMask paraFormatMask;

paraFormatMask.SetAttrib( EAttAlignment ); // set mask

paraFormat.iHorizontalAlignment = CParaFormat::ECenterAlign;

iGKeyEd->ApplyParaFormatL( ¶Format, paraFormatMask );

iGKeyEd->GetText(iKeyText); //获取编辑框中的内容，保存到iKeyText中

RESOURCE GTXTED R_RESOURCE_EDITOR //编辑框资源

{

flags = EAknEditorFlagDefault;

width = 53;

height = 16;

numlines = 1;

textlimit= 1;

fontcontrolflags = EGulFontControlAll;

fontnameflags = EGulNoSymbolFonts;

//这里也可设置输入法

// avkon_flags = EAknEditorFlagFixedCase |

EAknEditorFlagNoT9 | EAknEditorFlagSupressShiftMenu; //EAknEditorFlagSupressShiftMenu屏蔽切换输入法键

// allowed_input_modes = EAknEditorNumericInputMode;

// default_input_mode = EAknEditorNumericInputMode;

// numeric_keymap = EAknEditorPlainNumberModeKeymap;

}

注意，要使编辑框正常显示，记得更改container的CountComponentControls和ComponentControl函数，正确处理控件数目和编辑框指针。另外，要使编辑框能正常接收按键事件，要显示调用编辑框的OfferKeyEventL函数，如下：

Code:

TKeyResponse CMobileGuardSetKeyContainer::OfferKeyEventL( const TKeyEvent& aKeyEvent, TEventCode aType )

{

return iGKeyEd->OfferKeyEventL( aKeyEvent, aType );

}
