关于控件Controls随Dialog改变大小 && CDialogResize的总结

一、问题描述

对话框所有控件Controls可随对话框Dialog大小比例的变化而变化位置和大小。

二、解决方法

1 声明一对double值存储原始对话框大小m_OriginX & m_OriginY

2 声明一个CRect的向量 m_RectVector存储每个控件Control的Rect大小

3 对话框初始化时，初始化CRect 向量

4 对话框响应OnSize时，处理控件变化。先获取当前对话框大小cx & cy，分别求X轴、Y轴的大小变化比例ratio[2]，

自m_RectVector中获取每个控件的左上角、右下角的点，两点的x、y值分别乘以ratio[0]、ratio[1]，再MoveWindow

到新的位置。

5 比较好的一次性处理所有控件的方法：Windows的API函数 GetWindow()

6 为了Resize不出问题，最好通过OnGetMinMaxInfo消息设置对话框的最小尺寸

三、源代码

// .h文件 double m_nOriginX;double m_nOriginY;std::vector<CRect> m_RectVector;void InitRectVector();void ReSize();

// .cpp文件// OnInitDialog()初始化中添加如下代码CRect rect;      GetClientRect(&rect);     //取客户区大小    m_nOriginX = double(rect.right - rect.left);  m_nOriginY = double(rect.bottom - rect.top);

// .cpp文件void CTempChamberDlg::InitPtVector(){    int id;    CRect rt;    HWND  hChild = ::GetWindow(m_hWnd, GW_CHILD);      while(hChild)          {              id = ::GetDlgCtrlID(hChild);         GetDlgItem(id)->GetWindowRect(rt);            ScreenToClient(rt);            m_PtVector.push_back(rt);        hChild = ::GetWindow(hChild, GW_HWNDNEXT);          } }void CTempChamberDlg::ReSize()  {      double ratio[2];        CRect rt;          GetClientRect(&rt);     //取客户区大小        double cx = rt.right - rt.left;      double cy = rt.bottom - rt.top;      ratio[0] = (double)cx / m_nOriginX;      ratio[1] = (double)cy / m_nOriginY;      int id;    CRect Rect;      CPoint OldTLPoint, TLPoint; //左上角      CPoint OldBRPoint, BRPoint; //右下角     std::vector<CRect>::iterator iter = m_PtVector.begin();    HWND  hChild = ::GetWindow(m_hWnd, GW_CHILD);  //列出所有控件        while(hChild)          {              id = ::GetDlgCtrlID(hChild);//取得ID                    OldTLPoint = (*iter).TopLeft();            TLPoint.x = long(OldTLPoint.x * ratio[0]);            TLPoint.y = long(OldTLPoint.y * ratio[1]);        OldBRPoint = (*iter).BottomRight();            BRPoint.x = long(OldBRPoint.x * ratio[0]);            BRPoint.y = long(OldBRPoint.y * ratio[1]);         Rect.SetRect(TLPoint,BRPoint);            GetDlgItem(id)->MoveWindow(Rect,TRUE);  ++iter;        hChild = ::GetWindow(hChild, GW_HWNDNEXT);          }}

// .cpp文件// OnSize消息 & OnGetMinMaxInfo消息BEGIN_MESSAGE_MAP(CTempChamberDlg, CDialog)    //}}AFX_MSG_MAP    ON_WM_SIZE()    ON_WM_GETMINMAXINFO()END_MESSAGE_MAP()void CTempChamberDlg::OnSize(UINT nType, int cx, int cy){    CDialog::OnSize(nType, cx, cy);    if (nType==SIZE_RESTORED||nType==SIZE_MAXIMIZED)      {          ReSize();      }}void CTempChamberDlg::OnGetMinMaxInfo(MINMAXINFO* lpMMI){    lpMMI->ptMinTrackSize = m_ptMinTrackSize;    CDialog::OnGetMinMaxInfo(lpMMI);}
