/** @class wxPropertyGrid
wxPropertyGrid is a specialized grid for editing properties - in other
words name = value pairs. List of ready-to-use property classes include
strings, numbers, flagsets, fonts, colours and many others. It is possible,
for example, to categorize properties, set up a complete tree-hierarchy,
add more than two columns, and set arbitrary per-property attributes.
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.
See also @ref overview_propgrid.
@section propgrid_window_styles_ Window Styles
See @ref propgrid_window_styles.
@section propgrid_event_handling Event Handling
To process input from a propertygrid control, use these event handler macros to
direct input to member functions that take a wxPropertyGridEvent argument.
@beginEventTable{wxPropertyGridEvent}
@event{EVT_PG_SELECTED (id, func)}
Respond to wxEVT_PG_SELECTED event, generated when property value
has been changed by user.
@event{EVT_PG_CHANGING(id, func)}
Respond to wxEVT_PG_CHANGING event, generated when property value
is about to be changed by user. Use wxPropertyGridEvent::GetValue()
to take a peek at the pending value, and wxPropertyGridEvent::Veto()
to prevent change from taking place, if necessary.
@event{EVT_PG_HIGHLIGHTED(id, func)}
Respond to wxEVT_PG_HIGHLIGHTED event, which occurs when mouse
moves over a property. Event's property is NULL if hovered area does
not belong to any property.
@event{EVT_PG_RIGHT_CLICK(id, func)}
Respond to wxEVT_PG_RIGHT_CLICK event, which occurs when property is
clicked on with right mouse button.
@event{EVT_PG_DOUBLE_CLICK(id, func)}
Respond to wxEVT_PG_DOUBLE_CLICK event, which occurs when property is
double-clicked onwith left mouse button.
@event{EVT_PG_ITEM_COLLAPSED(id, func)}
Respond to wxEVT_PG_ITEM_COLLAPSED event, generated when user collapses
a property or category..
@event{EVT_PG_ITEM_EXPANDED(id, func)}
Respond to wxEVT_PG_ITEM_EXPANDED event, generated when user expands
a property or category..
@endEventTable
@remarks
- Use Freeze() and Thaw() respectively to disable and enable drawing. This
will also delay sorting etc. miscellaneous calculations to the last possible
moment.
