CAD二次开发学习笔记五(在ObjectARX中使用MFC)
要实现的功能是：
执行ArxModal命令，弹出如图所示对话框
选择点，则得到点坐标，选择角度则得到角度值。
步骤一：新建基于MFC的ObjectArx项目，
参考：http://www.cnblogs.com/greatverve/archive/2010/05/31/ObjectARX-HelloWorld.html
打开资源视图添加一个对话框ID修改为IDD_ARX_MODAL
(右击资源视图中的对话框打开属性面板，可以修改ID)
设计如图界面，ID如下：
IDC_BUTTON_POINT
IDC_BUTTON_ANGLE
IDC_EDIT_XPT
IDC_EDIT_YPT
IDC_EDIT_ZPT
IDC_EDIT_ANGLE
选择两个Button把Owner Draw设置为True
完成界面。
步骤二：
打开类视图，右击项目->添加类(这里不是右击对话框添加类)
这张图有点小错误，这里Dialog ID:IDD_ARX_MODAL Class name:CArxDialog
在类视图中右击CArxDialog类添加变量
这样会在头文件中生成
源文件中生成
根据这个规律添加其他变量
大气象
private:
CAcUiPickButton m_btnAngle;
CAcUiPickButton m_btnPoint;
CAcUiNumericEdit m_editXpt;
CAcUiNumericEdit m_editYpt;
CAcUiNumericEdit m_editZpt;
CAcUiAngleEdit m_editAngle;
void CArxDialog::DoDataExchange (CDataExchange *pDX) {
CAcUiDialog::DoDataExchange (pDX) ;
DDX_Control(pDX, IDC_BUTTON_ANGLE, m_btnAngle);
DDX_Control(pDX, IDC_BUTTON_POINT, m_btnPoint);
DDX_Control(pDX, IDC_EDIT_XPT, m_editXpt);
DDX_Control(pDX, IDC_EDIT_YPT, m_editYpt);
DDX_Control(pDX, IDC_EDIT_ZPT, m_editZpt);
DDX_Control(pDX, IDC_EDIT_ANGLE, m_editAngle);
}
CAcUiPickButton m_btnAngle;
CAcUiPickButton m_btnPoint;
CAcUiNumericEdit m_editXpt;
CAcUiNumericEdit m_editYpt;
CAcUiNumericEdit m_editZpt;
CAcUiAngleEdit m_editAngle;
void CArxDialog::DoDataExchange (CDataExchange *pDX) {
CAcUiDialog::DoDataExchange (pDX) ;
DDX_Control(pDX, IDC_BUTTON_ANGLE, m_btnAngle);
DDX_Control(pDX, IDC_BUTTON_POINT, m_btnPoint);
DDX_Control(pDX, IDC_EDIT_XPT, m_editXpt);
DDX_Control(pDX, IDC_EDIT_YPT, m_editYpt);
DDX_Control(pDX, IDC_EDIT_ZPT, m_editZpt);
DDX_Control(pDX, IDC_EDIT_ANGLE, m_editAngle);
}
步骤三：
为CArxDialog添加InitDialog消息响应。
方法是打开类视图，右击->属性
再添加OnClose()响应函数
在头文件中添加几个变量
public:
CString m_strAngle;
CString m_strZPt;
CString m_strYPt;
CString m_strXPt;
在头文件中定义两函数
void DisplayPoint();
void DisplayAngle();
分别为两个按钮添加单击事件，为四个编辑框添加失去焦点事件。
步骤四：
打开acrxEntryPoint.cpp添加#include “ArxDialog.h”
运行结果如图
