电子元器件系统

电子元器件系统代码分析 一、 类的定义与实现 1、 器件类  器件类定义 class CComponent : public CObject { public: static COLORREF m_fillColor;//由类的所有对象共享 BOOL IsNum(CString str); BOOL IsInList(int i,CObList *pNumList); DECLARE_SERIAL(CComponent)

void Serialize(CArchive& ar); void SetName(const CString &Name); CString GetName(); virtual void Draw(CDC *pDC); virtual CString CalculateName(CObList *pList); float GetRotateAngle(); void SetRotateAngle(float angle); BOOL GetIsSelected(); void SetIsSelected(BOOL IsSel); int GetLineWidth(); void SetLineWidth(int LWidth); void SetColor(COLORREF color); COLORREF GetColor(); CComponent(); virtual ~CComponent();

private: float m_RotateAngle; BOOL m_IsSelected; int m_iLineWidth; COLORREF m_Color; CString m_strName; };  器件类实现 COLORREF CComponent::m_fillColor = RGB(176,176,176); //在文件范围内初始化 CComponent::CComponent() { m_RotateAngle = 0; m_IsSelected = FALSE; //m_iLineWidth = 4; m_iLineWidth = 40; m_Color = RGB(0,0,255); }

CComponent::~CComponent() {

} COLORREF CComponent::GetColor() { return m_Color; }

void CComponent::SetColor(COLORREF color) { m_Color = color; }

void CComponent::SetLineWidth(int LWidth) { m_iLineWidth = LWidth; }

int CComponent::GetLineWidth() { return m_iLineWidth; }

void CComponent::SetIsSelected(BOOL IsSel) { m_IsSelected = IsSel; }

BOOL CComponent::GetIsSelected() { return m_IsSelected; }

void CComponent::SetRotateAngle(float angle) { m_RotateAngle = angle; }

float CComponent::GetRotateAngle() { return m_RotateAngle; } CString CComponent::CalculateName(CObList *pObList) { return "器件"; }

void CComponent::Draw(CDC *pDC) {

} CString CComponent::GetName() { return m_strName; }

void CComponent::SetName(const CString &Name) { m_strName = Name; }

void CComponent::Serialize(CArchive &ar) { if (ar.IsStoring()) { ar<} else { ar>>m_Color>>m_iLineWidth>>m_strName>>m_RotateAngle; } }

BOOL CComponent::IsInList(int i, CObList *pNumList) //判断数字i是否在链表pNumList中 { POSITION pos = pNumList->GetHeadPosition(); CObject *pObject; int *p; while(pos != NULL) { pObject = pNumList->GetAt(pos); p = (int *)pObject; if (i == (*p)) { return TRUE; } pNumList->GetNext(pos); } return FALSE; } BOOL CComponent::IsNum(CString str) //判断一个字符串是否是数字,在各个派生类的CalculateName函数中 //使用,系统提供的函数atoi()将类似于"12ert"之类的串转换为12, //这显然是不正确的,因此自己开发了这个小函数 { int len = str.GetLength(); char ch; for (int i = 1; i<= len; i++) { ch = str.GetAt(i-1); if (!(ch<='9' && ch>='0')) { return FALSE; } } return TRUE; } 2、 电阻类的定义与实现  电阻类的定义 #include "Component.h"//包含基类的头文件 typedef struct struc_Resistor { char m_strClassType[20]; //COLORREF m_color; //int m_iLineWidth; BOOL m_IsSelected; //float m_RotateAngle; char m_strName[100]; //char m_ReType[100];//电阻的类型 //char m_ReValue[100];//电阻的阻值 }RESISTOR;

class CResistor : public CComponent { public: void CopyReToStruRe(RESISTOR &Resistor); //将电阻对象拷贝到电阻结构中 CResistor(RESISTOR Resistor); void GetNumInNameSer(CObList *pObList,CObList *pNumSer,int *pMax); //取得已绘制的电阻名称中的数字序列 CResistor(CPoint *pt); DECLARE_SERIAL(CResistor) void Serialize(CArchive& ar); void PrepareDrawChipDC(CDC *pDC); void Draw(CDC *pDC); CString CalculateName(CObList *pObList); void SetReValue(CString &ReValue); void SetReType(CString &ReType); CString GetReValue(); CString GetReType(); CRect m_Rect; CRect m_RectLP; CRectTracker m_RectTracker; CResistor(); virtual ~CResistor();

private: CString m_ReType; CString m_ReValue; };  电阻类的实现 CResistor::CResistor() { //m_Rect = CRect(0,0,100,60); m_Rect = CRect(0,0,2000,-1000); m_RectLP = m_Rect; m_RectTracker.m_rect = m_Rect; m_RectTracker.m_nStyle = CRectTracker::resizeOutside; SetName("R"); }

CResistor::~CResistor() {

} CString CResistor::GetReType() { return m_ReType; }

CString CResistor::GetReValue() { return m_ReValue; }
