  34
  35     Holder of property grid page information. You can subclass this and
  36     give instance in wxPropertyGridManager::AddPage. It inherits from
  37     wxEvtHandler and can be used to process events specific to this
  38     page (id of events will still be same as manager's). If you don't
  39     want to use it to process all events of the page, you need to
  40     return false in the derived wxPropertyGridPage::IsHandlingAllEvents.
  41
  42     Please note that wxPropertyGridPage lacks many non-const property
  43     manipulation functions found in wxPropertyGridManager. Please use
  44     parent manager (m_manager member variable) when needed.
  45
  46     Please note that most member functions are inherited and as such not
  47     documented on this page. This means you will probably also want to read
  48     wxPropertyGridInterface class reference.
  49
  50     @section propgridpage_event_handling Event Handling
  51
  52     wxPropertyGridPage receives events emitted by its wxPropertyGridManager, but
  53     only those events that are specific to that page. If
  54     wxPropertyGridPage::IsHandlingAllEvents returns false, then unhandled
  55     events are sent to the manager's parent, as usual.
  56
  57     See @ref propgrid_event_handling "wxPropertyGrid Event Handling"
  58     for more information.
