A DlgResizeHelper object helps you with layouting a dialog or - more generally - a window with child windows. In contrast to other solutions DlgResizeHelper is not derived from CDialog so it can be used with every window. On initialization a DlgResizeHelper stores handles to all child windows of a parent window. On resize it resizes the child windows according to the size changes of the parent. By default a child is resized proportional to the parent size but you can optionally fix the horizontal and/or vertical dimension/position of a sub window. E.g. it's reasonable to fix the height of single line edit controls. Usage (here e.g. with a dialog class): 1. Make your dialog resizable (give it a resizable border) 2. Add a DlgResizeHelper member to your dialog class: #include "DlgResizeHelper.h" class CMyDialog : public CDialog { //... DlgResizeHelper m_resizeHelper; CPoint m_origSize; // this is an optional member which holds the original size for OnGetMinMaxInfo() //... }; 3. Initialize the resize helper in OnInitDialog(): BOOL CMyDialog::OnInitDialog() { //... m_resizeHelper.Init(m_hWnd); // default behaviour is to resize sub windows proportional to the resize of the parent // you can fix horizontal and/or vertical dimensions for some sub windows by either specifying the sub window by // * its hwnd: m_resizeHelper.Fix(m_buttonCtrl, DlgResizeHelper::kLeft, DlgResizeHelper::kNoVFix); // * its item id: m_resizeHelper.Fix(IDC_PRESS_ME, DlgResizeHelper::kWidth, DlgResizeHelper::kNoVFix); // * or all sub windows with a common class name (especially useful for single line edit controls) m_resizeHelper.Fix("Edit", DlgResizeHelper::kNoHFix, DlgResizeHelper::kHeight); // initialize the optional origSize member CRect rect; GetWindowRect(rect); m_origSize = CPoint(rect.Width(), rect.Height()); //... } 4. Tell the resize helper when the size has changed: void CMyDialog::OnSize(UINT nType, int cx, int cy) { CDialog::OnSize(nType, cx, cy); m_resizeHelper.OnSize(); } (5. optionally: enforce minimal dialog size) void CDlg_resizerDlg::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI ) { lpMMI->ptMinTrackSize = m_origSize; } The sample application is a dialog with a bunch of buttons. The name of the buttons reveals their fixed dimensions.
