第一步、在對話框類中(.h檔案)定義如下變量和函數
[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 計算出原始對話框的大小
[cpp] view plain copy
- CRect rect;
- GetClientRect(&rect); //取客戶區大小
- 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、重新整理控件函數
[cpp] view plain copy
- void CStuDemoDlg::ReSize()
- {
- float fsp[2];
- POINT Newp; //擷取現在對話框的大小
- CRect recta;
- GetClientRect(&recta); //取客戶區大小
- 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;
- }
