Symbian 控件架构之对话框

核心提示：Code:control = EDWIN{flags = EEikEdwinNoHorizScrolling | EEikEdwinResizable;width = 11;lines = 1;maxlength = 11;avkon_flags = EAknEditorFlagFixedCase |EAknEdito

Code:

control = EDWIN

{

flags = EEikEdwinNoHorizScrolling | EEikEdwinResizable;

width = 11;

lines = 1;

maxlength = 11;

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;

};

以上写法表示默认输入法为数字，并且屏蔽了输入法切换键，即不能通过输入法切换键来切换输入法。

6、编辑框

编辑框使用的类：

CEikGlobalTextEditor

头文件：eikgted.h

使用方法：

Code:

CEikGlobalTextEditor* iGKeyEd;

TBuf<128> iKeyText;

TResourceReader reader;

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
