Symbian 对话框用法

核心提示：buttons = R_AVKON_SOFTKEYS_OK_CANCEL;items ={DLG_LINE{type = EAknCtQuery;id = EGeneralQuery;control= AVKON_DATA_QUERY{layout = ENumberLayout;label = qtn_aknexqu

buttons = R_AVKON_SOFTKEYS_OK_CANCEL;

items =

{

DLG_LINE

{

type = EAknCtQuery;

id = EGeneralQuery;

control= AVKON_DATA_QUERY

{

layout = ENumberLayout;

label = qtn_aknexquery_num_label_text;

control = AVKON_INTEGER_EDWIN

// 这个AKNEXQUERY_NUMBER_EDITOR_MIN在帮助中没有找到 设置上下限 这个在UI设计中可以再属性列表下找到

{

min = AKNEXQUERY_NUMBER_EDITOR_MIN;

max = AKNEXQUERY_NUMBER_EDITOR_MAX;

};

};

}

};

}

数字请求对话框对应的类是：CAknNumberQueryDialog。下面代码示例之：

#include // all the query dialog listed here

TInt number(123456);

// create dialog instance; number is the descriptor that is used for // the editor

CAknNumberQueryDialog* dlg = new (ELeave) CAknNumberQueryDialog (number);

// Prepares the dialog, constructing it from the specified resource

dlg->PrepareLC(R_AKNEXQUERY_NUMBER_LAYOUT);

// Set maximum and minimum to editor. This overrides values given in // resource. - optional

dlg->SetMinimumAndMaximum( 0, 1000000 );

//这里又设置下 有点不懂 查帮助 Set minimum and maximum number to editor. 上面是定义资源 这里才是实现

// Launch the dialog

if (dlg->RunLD())

{

// ok pressed, number is the entered number in the editor.

}

以下这些都来自网络 本人没有仔细分析 请楼下的大牛帮助本人 谢谢

时间/日期请求对话框

RESOURCE DIALOG r_aknexquery_time_query

{

flags = EGeneralQueryFlags;

buttons = R_AVKON_SOFTKEYS_OK_CANCEL;

items =

{

DLG_LINE

{

type = EAknCtQuery;

id = EGeneralQuery;
