//////////////////////////////////////////////////////////////////////// // ResizingDialog.cpp : implementation file // // The base class for the dialog box you want to allow resizing // Use SetConrolInfo() to determine how each control behaves when // the user resize the dialog box. // (The "Windows default" is ANCHORE_TOP | ANCHORE_LEFT) // // e.g. For a right aligned OK button you'll probably call: // SetControlInfo(IDOK, ANCHORE_RIGHT) // For a text control that needs to resize with the dialog you may do: // SetControlInfo(IDD_MYEDITOR, RESIZE_BOTH) // // Note: The dialog box "remebers" its size on destroy and the next time // you launch it, it'll set the dialog size back to the previous size. // If you don't like this behavior, call SetRememberSize(FALSE) // // LIMITATIONS: // 1) This class does not handle overlapping controls, // e.g., you cannot place two controls one (RESIZE_VER) and the other // with (RESIZE_VER | ANCHORE_BOTTOM) one below the other, they may ovelapp. // // 2) This class does not remember the mode of the dialog (Maximized/Minimized) // it would be easy to add this feature, though. #include "stdafx.h" #include "ResizingDialog.h" #ifdef _DEBUG #undef THIS_FILE static char BASED_CODE THIS_FILE[] = __FILE__; #endif ///////////////////////////////////////////////////////////////////////////// // CResizingDialog dialog CResizingDialog::CResizingDialog(UINT nIDTemplate, CWnd* pParentWnd) : CDialog(nIDTemplate,pParentWnd) { m_minWidth = m_minHeight = 0; // flag that GetMinMax wasn't called yet m_old_cx = m_old_cy = 0; m_bSizeChanged = FALSE; m_nIDTemplate = nIDTemplate; m_bRememberSize = TRUE; } void CResizingDialog::SetControlInfo(WORD CtrlId,WORD Anchore) { if(Anchore == ANCHORE_LEFT) return; // Do nothing // Add resizing behaviour for the control DWORD c_info = CtrlId | (Anchore << 16); m_control_info.Add(c_info); } BEGIN_MESSAGE_MAP(CResizingDialog, CDialog) //{{AFX_MSG_MAP(CResizingDialog) ON_WM_SIZE() ON_WM_GETMINMAXINFO() ON_WM_DESTROY() ON_WM_CREATE() //}}AFX_MSG_MAP END_MESSAGE_MAP() ////////////////////////////////////////////////////////////////////////// // CResizingDialog message handlers ////////////////////////////////////////////////////////////////////////// // OnInitDialog() // BOOL CResizingDialog::OnInitDialog() { CDialog::OnInitDialog(); if(m_bRememberSize) { // Load the previous size of the dialog box from the INI/Registry char dialog_name[7]; itoa(m_nIDTemplate, dialog_name, 16); int cx = AfxGetApp()->GetProfileInt(dialog_name,"CX",0); int cy = AfxGetApp()->GetProfileInt(dialog_name,"CY",0); if(cx && cy) { SetWindowPos( NULL, 0, 0, cx, cy, SWP_NOMOVE ); } } return FALSE; // return TRUE unless you set the focus to a control } void CResizingDialog::OnSize(UINT nType, int cx, int cy) { CDialog::OnSize(nType, cx, cy); int dx = cx - m_old_cx; int dy = cy - m_old_cy; if(m_old_cx) { // Move and Size the controls using the information // we got in SetControlInfo() // m_bSizeChanged = TRUE; CRect WndRect; CWnd *pWnd; DWORD c_info; short Anchore; for(int i = 0; i < m_control_info.GetSize(); i++) { c_info = m_control_info[i]; pWnd = GetDlgItem(LOWORD(c_info)); if(!pWnd) { TRACE("Control ID - %d NOT FOUND!!\n",LOWORD(c_info)); continue; } if(!HIWORD(c_info)) continue; // do nothing if anchored to top and or left Anchore = HIWORD(c_info); pWnd->GetWindowRect(&WndRect); ScreenToClient(&WndRect); if(Anchore & RESIZE_HOR) WndRect.right += dx; else if(Anchore & ANCHORE_RIGHT) WndRect.OffsetRect(dx,0); if(Anchore & RESIZE_VER) WndRect.bottom += dy; else if(Anchore & ANCHORE_BOTTOM) WndRect.OffsetRect(0,dy); pWnd->MoveWindow(&WndRect); } } m_old_cx = cx; m_old_cy = cy; } void CResizingDialog::OnGetMinMaxInfo(MINMAXINFO* lpMMI) { if (!m_minWidth) // first time { CDialog::OnGetMinMaxInfo(lpMMI); return; } lpMMI->ptMinTrackSize.x = m_minWidth; lpMMI->ptMinTrackSize.y = m_minHeight; } void CResizingDialog::OnDestroy() { // Save the size of the dialog box, so next time // we'll start with this size if(m_bRememberSize && m_bSizeChanged && m_old_cx && m_old_cy) { CRect rc; GetWindowRect(&rc); char dialog_name[7]; itoa(m_nIDTemplate, dialog_name, 16); AfxGetApp()->WriteProfileInt(dialog_name,"CX",rc.Width()); AfxGetApp()->WriteProfileInt(dialog_name,"CY",rc.Height()); } m_minWidth = m_minHeight = m_old_cx = m_old_cy = 0; m_bSizeChanged = FALSE; CDialog::OnDestroy(); } int CResizingDialog::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (CDialog::OnCreate(lpCreateStruct) == -1) return -1; // Remember the original size so later we can calculate // how to place the controls on dialog Resize m_minWidth = lpCreateStruct->cx; m_minHeight = lpCreateStruct->cy; return 0; }
