The coderealigns the controls that are beneath the tab control, which have the WS_VISIBLE style.The controls are repositioned from right to left, in reverse tab order, and beingseparated by a standard distance. This is handy for realigning the controls after you havechanged the visibile state of the buttons at the bottom of the property sheet. You canalso use this function during OnInitDialog(..) as the visible state of the controls isobtained by checking the window style of the child control, and not by usingIsWindowVisible(..).<font COLOR="#990000"><tt></p><pre>void CPropertySheetDerivedClass::AutoArrangeButtons() { CWnd* pWnd = GetDlgItem(ID_APPLY_NOW); if (pWnd && ::IsWindow(pWnd->m_hWnd)) { // Get the last control in the tab order - (tab order is the same as creation order) pWnd = pWnd->GetWindow(GW_HWNDLAST); // Get the tab control CTabCtrl* pTabCtrl = GetTabControl(); // Get the child identifier of the tab control int nTabControlID = ::GetWindowLong(pTabCtrl->m_hWnd, GWL_ID); // Child control identifier int nControlID = 0; // The window rect of the tab control.
