33 /** @class wxPropertyGridPage
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"
