第一步、在对话框类中（.h文件）定义如下变量和函数
定义如下几个变量：
[cpp] view plain copy void ReSize(int nID); BOOL change_flag; float m_Multiple_height; float m_Multiple_width; [cpp] view plain copy afx_msg void OnSize(UINT nType, int cx, int cy);
第二步、在OnInitDialog()中 计算出当前对话框的大小与最大化后大小
[cpp] view plain copy CRect rect; ::GetWindowRect(m_hWnd,rect);//这里m_hWnd为窗口句柄，如果不存在此变量则在该行代码前加一句：HWND h_Wnd=GetSafeHwnd( ); ScreenToClient(rect); LONG m_nDlgWidth = rect.right - rect.left; LONG m_nDlgHeight = rect.bottom - rect.top; //Calc 分辨率 LONG m_nWidth = GetSystemMetrics(SM_CXSCREEN); LONG m_nHeight = GetSystemMetrics(SM_CYSCREEN); //计算放大倍数(要用float值，否则误差很大) m_Multiple_width = float(m_nWidth)/float(m_nDlgWidth); m_Multiple_height = float(m_nHeight)/float(m_nDlgHeight); change_flag = TRUE;//用来判断OnSize执行时，OninitDialg是否已经执行了
第三步、给对话框添加 WM_SIZE消息
[cpp] view plain copy //给对话框添加 VM_SIZE消息 void CStuDemoDlg::OnSize(UINT nType, int cx, int cy) { CDialog::OnSize(nType, cx, cy); // TODO: Add your message handler code here if (change_flag)//如果OninitDlg已经调用完毕 { ReSize(IDC_STATIC_1); ReSize(IDC_STATIC_2); ReSize(IDC_EDIT11);// ReSize(IDC_EDIT12);// ReSize(IDC_LIST_SHOW);//LIST ReSize(IDC_BUTTON_ADD); ReSize(IDC_BUTTON_DEL); ReSize(IDOK); ReSize(IDCANCEL); //恢复放大倍数，并保存 (确保还原时候能够还原到原来的大小) m_Multiple_width = float(1)/m_Multiple_width; m_Multiple_height = float(1)/m_Multiple_height; } }
第四步、刷新控件：根据比例计算控件缩放的大小，然后movewindow 到新矩形上
[cpp] view plain copy void CStuDemoDlg::ReSize(int nID) { CRect Rect; GetDlgItem(nID)->GetWindowRect(Rect); ScreenToClient(Rect); //计算控件左上角点 CPoint OldTLPoint,TLPoint; OldTLPoint = Rect.TopLeft(); TLPoint.x = long(OldTLPoint.x *m_Multiple_width); TLPoint.y = long(OldTLPoint.y * m_Multiple_height ); //计算控件右下角点 CPoint OldBRPoint,BRPoint; OldBRPoint = Rect.BottomRight(); BRPoint.x = long(OldBRPoint.x *m_Multiple_width); BRPoint.y = long(OldBRPoint.y * m_Multiple_height ); //移动控件到新矩形 Rect.SetRect(TLPoint,BRPoint); GetDlgItem(nID)->MoveWindow(Rect,TRUE); }
第一步、在对话框类中（.h文件）定义如下变量和函数
[cpp] view plain copy void ReSize(); POINT old; [cpp] view plain copy afx_msg void OnSize(UINT nType, int cx, int cy);
第二步、在OnInitDialog()中 计算出原始对话框的大小
[cpp] view plain copy CRect rect; GetClientRect(&rect); //取客户区大小 old.x=rect.right-rect.left; old.y=rect.bottom-rect.top;
第三步、添加 WM_SIZE消息
[cpp] view plain copy void CStuDemoDlg::OnSize(UINT nType, int cx, int cy) { CDialog::OnSize(nType, cx, cy); // TODO: Add your message handler code here if (nType==SIZE_RESTORED||nType==SIZE_MAXIMIZED) { ReSize(); } }
第四步、刷新控件函数
[cpp] view plain copy void CStuDemoDlg::ReSize() { float fsp[2]; POINT Newp; //获取现在对话框的大小 CRect recta; GetClientRect(&recta); //取客户区大小 Newp.x=recta.right-recta.left; Newp.y=recta.bottom-recta.top; fsp[0]=(float)Newp.x/old.x; fsp[1]=(float)Newp.y/old.y; CRect Rect; int woc; CPoint OldTLPoint,TLPoint; //左上角 CPoint OldBRPoint,BRPoint; //右下角 HWND hwndChild=::GetWindow(m_hWnd,GW_CHILD); //列出所有控件 while(hwndChild) { woc=::GetDlgCtrlID(hwndChild);//取得ID GetDlgItem(woc)->GetWindowRect(Rect); ScreenToClient(Rect); OldTLPoint = Rect.TopLeft(); TLPoint.x = long(OldTLPoint.x*fsp[0]); TLPoint.y = long(OldTLPoint.y*fsp[1]); OldBRPoint = Rect.BottomRight(); BRPoint.x = long(OldBRPoint.x *fsp[0]); BRPoint.y = long(OldBRPoint.y *fsp[1]); Rect.SetRect(TLPoint,BRPoint); GetDlgItem(woc)->MoveWindow(Rect,TRUE); hwndChild=::GetWindow(hwndChild, GW_HWNDNEXT); } old=Newp;
就个人而言，本人还是比较倾向第二种方法，毕竟可以少操作控件ID，否则少了一个布局都会发生变化。
