Symbian 控件架构之对话框

核心提示：RESOURCE GTXTED R_RESOURCE_EDITOR //编辑框资源{flags = EAknEditorFlagDefault;width = 53;height = 16;numlines = 1;textlimit= 1;fontcontrolflags = EGulFontControlAll;f

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 );

}

标准对话框

Symbian OS中的对话框都从CAknDialog中继承，大多数对话框是一个容器，可以容纳其他控件。下面示例如何在资源文件中定义一个带有编辑框的对话框：

RESOURCE DIALOG r_dialog_edit_dialog

{

flags = EEikDialogFlagNoDrag | EEikDialogFlagCbaButtons | EEikDialogFlagWait;

buttons = R_AVKON_SOFTKEYS_OK_CANCEL;

items = {

DLG_LINE

{

id = EConfirmationNoteDlgCIdFileName;

type = EEikCtLabel;

control = LABEL { };

},

DLG_LINE

{

id = EConfirmationNoteDlgCIdEditor;

type = EEikCtEdwin;

control = EDWIN { maxlength = 20; };

}

};

}

DIALOG有以下几个属性需要设置：
