步骤：

1.创建对话框框架

2.实现对话框中按钮的功能

1． 对话框框架搭建

框架搭建与第一节框架搭建一样，再次不再累述。针对对话框框架的搭建，在LocalInterfaces中，有CAADialogApplicationDlg.CATDlg文件。点击此文件会弹出工具条，用此工具条对对话框进行布局。效果图如下：

CAA二次开发-创建对话框

2.实现按钮功能

2.1Combo（年龄一栏）的初始化

在void CAADialogApplicationDlg::Build(){}中，添加如下代码

///对Combo进行初始化

CATUnicodeString ComboNum[30];//声明CATUnicodeString类型的数组（Combo容量）

for (int i = 0;i<30;i++)

{

//将int类型的数转换为CATUcicodeString类型

ComboNum[i].BuildFromNum(i+20,"%d");

//对Combo中的行设置数值

_ShowAge ->SetLine(ComboNum[i],i);

}

//设置默认行

_ShowAge->SetSelect(0);

2.2获取姓名功能实现

将鼠标放到获取姓名按钮，右键选择callback wizard…，弹出对话框，选择Button activation选项，点击Add callback…按钮，在CAADialogApplicationDlg.cpp文件中会自动添加void CAADialogApplicationDlg::OnGetNameButtonPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)

{

}方法，在此方法中添加如下代码：

void CAADialogApplicationDlg::OnGetNameButtonPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)

{

//定义一的字符串

CATUnicodeString NameText;

//获取StudentName中的字符串

NameText = _StudentNameEditor->GetText();

//判断editor是否为空，如果为空，弹出“请输入姓名：”的对话框

//如果不为空，弹出"你输入的姓名是：+姓名"的对话框

if(2==NameText.Compare(""))

{

_OpenNotify = new CATDlgNotify(this," ",CATDlgNfyWarning);

_OpenNotify -> SetText("请输入姓名：");

_OpenNotify ->SetVisibility(CATDlgShow);

}

else

{

_OpenNotify = new CATDlgNotify(this," ",CATDlgNfyInformation);

_OpenNotify -> SetText("你输入的姓名是：n"+NameText);

_OpenNotify ->SetVisibility(CATDlgShow);

}

}

2.3获取性别功能实现

将鼠标放到获取性别按钮，右键选择callback wizard…，弹出对话框，选择Button activation选项，点击Add callback…按钮，在CAADialogApplicationDlg.cpp文件中会自动添加void CAADialogApplicationDlg::OnGetGenderPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)

{ }在其中添加代码如下：

void CAADialogApplicationDlg::OnGetGenderPushBActivateNotification(CATCommand* cmd, CATNotification* evt, CATCommandClientData data)

{

//判断是否选中状态，如果都没被选中，弹出”请选择性别对话框“

if (_ManRadioButton->GetState()!=CATDlgCheck && _WomanRadioButton->GetState()!=CATDlgCheck)

{

_OpenNotify = new CATDlgNotify(this," ",CATDlgNfyWarning);

_OpenNotify -> SetText("请选择性别");

_OpenNotify ->SetVisibility(CATDlgShow);

}

运行结果：

//如果”男“被选中弹出”你选择的性别是：男“

else if(_ManRadioButton->GetState()==CATDlgCheck)

{

_OpenNotify = new CATDlgNotify(this," ",CATDlgNfyOK);

_OpenNotify -> SetText("你选择的性别是：男");

_OpenNotify ->SetVisibility(CATDlgShow);

}

运行结果：

//如果“女”被选中，弹出你选择的性别是：女

else

{

_OpenNotify = new CATDlgNotify(this," ",CATDlgNfyOK);

_OpenNotify -> SetText("你选择的性别是：女");

_OpenNotify ->SetVisibility(CATDlgShow);

}

}

运行结果：

{

//声明一个CATUnicodeStrng类型的数组

CATUnicodeString iText[3];

//判断多选按钮是否都没选中，如果是弹出“请选择学科”的对话框，否则就显示“你选择的科目是：+所选学科”

if (_YUWEN->GetState()!=CATDlgCheck && _English->GetState()!=CATDlgCheck && _Math->GetState()!=CATDlgCheck)

{

_OpenNotify = new CATDlgNotify(this," ",CATDlgNfyError);

_OpenNotify ->SetText("请选择学科");

_OpenNotify ->SetVisibility(CATDlgShow);

}

运行结果：

else

{

int i = 0;

if (_YUWEN->GetState()==CATDlgCheck)

{

iText[i++] = _Label059->GetTitle();

}

if (_English->GetState()==CATDlgCheck)

{

iText[i++] = _Label060->GetTitle();

}

if (_Math->GetState()==CATDlgCheck)

{

iText[i++] = _Label061->GetTitle();

}

_OpenNotify = new CATDlgNotify(this," ",CATDlgNfyWarning);

_OpenNotify ->SetText("你选择的科目是：n"+ iText[0]+"，"+ iText[1]+"，"+ iText[2]);

_OpenNotify->SetVisibility(CATDlgShow);

}

}

{

CATUnicodeString iText;//声明所选择Combo行的内容；

int LineNumber=_ShowAge->GetSelect();//获取所选行的行号

_ShowAge ->GetLine(iText,LineNumber);//获取所选行的内容

_OpenNotify = new CATDlgNotify(this," ",CATDlgNfyOK);//弹出信息对话框

_OpenNotify->SetText("年龄为："+iText);//对话框显示的内容

_OpenNotify ->SetVisibility(CATDlgShow);//显示对话框

}

//如果值大于.弹出“不幸福”对话框

//否则弹出“一般幸福”对话框

int i = _ShowStudyAge->GetCurrentValue();
