wxPG_NULL_BITMAP macro is not useful because is used only once. In the rest of wxPG code wxNullBitmap is used explicitly many times so for the sake of consistency we can resign from using this macro.

/** @class wxPropertyGridPage
|
|
|
|
Holder of property grid page information. You can subclass this and
|
|
give instance in wxPropertyGridManager::AddPage. It inherits from
|
|
wxEvtHandler and can be used to process events specific to this
|
|
page (id of events will still be same as manager's). If you don't
|
|
want to use it to process all events of the page, you need to
|
|
return false in the derived wxPropertyGridPage::IsHandlingAllEvents.
|
|
|
|
Please note that wxPropertyGridPage lacks many non-const property
|
|
manipulation functions found in wxPropertyGridManager. Please use
|
|
parent manager (m_manager member variable) when needed.
|
|
|
|
Please note that most member functions are inherited and as such not
|
|
documented on this page. This means you will probably also want to read
|
|
wxPropertyGridInterface class reference.
|
|
|
|
@section propgridpage_event_handling Event Handling
|
|
|
|
wxPropertyGridPage receives events emitted by its wxPropertyGridManager, but
|
|
only those events that are specific to that page. If
|
|
wxPropertyGridPage::IsHandlingAllEvents returns false, then unhandled
|
|
events are sent to the manager's parent, as usual.
|
|
|
|
See @ref propgrid_event_handling "wxPropertyGrid Event Handling"
|
|
for more information.
