Here is some code for realigning the controls present on a property sheet. The code
realigns 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 being
separated by a standard distance. This is handy for realigning the controls after you have
changed the visibile state of the buttons at the bottom of the property sheet. You can
also use this function during OnInitDialog(..) as the visible state of the controls is
obtained by checking the window style of the child control, and not by using
IsWindowVisible(..).
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. CRect rcTAB(0, 0, 0, 0); pTabCtrl->GetWindowRect(rcTAB); ScreenToClient(rcTAB); CRect rcTemp(0, 0, 0, 0); GetClientRect(rcTemp); int nLeft = rcTemp.right; int nSpacing = rcTemp.right - rcTAB.right; // do this bit while we have a control to do something with while(pWnd) { // Get the ID of the current child control nControlID = ::GetWindowLong(pWnd->m_hWnd, GWL_ID); // Do not make changes to the tab control!! if (nControlID != nTabControlID) { // do some stuff pWnd->GetWindowRect(rcTemp); ScreenToClient(rcTemp); // Is the child control visible? - Don't use IsWindowVisible as the parent // also has to be visible for that to return TRUE; BOOL bChildIsVisible = ((pWnd->GetStyle() & WS_VISIBLE) == WS_VISIBLE); // Make sure we are below the TAB control if ((rcTemp.top > rcTAB.bottom) && bChildIsVisible) { // Move each control nLeft -= nSpacing + rcTemp.Width(); pWnd->MoveWindow(nLeft, rcTemp.top, rcTemp.Width(), rcTemp.Height()); } } // Go back in the TAB order again pWnd = pWnd->GetWindow(GW_HWNDPREV); } } }
