Determines whether a tabbed dialog can be closed.
virtual BOOL CSftTabsDialog::ClosePossible();
The return value is TRUE if the dialog can be closed, otherwise FALSE is returned.
The ClosePossible function determines whether a tabbed dialog can be closed.
This function calls the CSftTabsPage::AllowSwitch member function of the currently active tab page. If the currently active page can be closed, the entire tabbed dialog can also be closed. An application can override this function to perform additional tests such as input validation, to determine if the dialog can be closed.
