@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, flag sets, 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.

@section propgrid_event_handling Event Handling
To process input from a property grid control, use these event handler macros
to direct input to member functions that take a wxPropertyGridEvent argument.
@beginEventEmissionTable{wxPropertyGridEvent}
@event{EVT_PG_SELECTED (id, func)}
Respond to wxEVT_PG_SELECTED event, generated when a property selection
has been changed, either by user action or by indirect program
function. For instance, collapsing a parent property programmatically
causes any selected child property to become unselected, and may
therefore cause this event to be generated.
@event{EVT_PG_CHANGED(id, func)}
Respond to wxEVT_PG_CHANGED event, generated when property value
has been changed by the 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 on with 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.
@event{EVT_PG_LABEL_EDIT_BEGIN(id, func)}
Respond to wxEVT_PG_LABEL_EDIT_BEGIN event, generated when user is
about to begin editing a property label. You can veto this event to
prevent the action.
@event{EVT_PG_LABEL_EDIT_ENDING(id, func)}
Respond to wxEVT_PG_LABEL_EDIT_ENDING event, generated when user is
about to end editing of a property label. You can veto this event to
prevent the action.
@event{EVT_PG_COL_BEGIN_DRAG(id, func)}
Respond to wxEVT_PG_COL_BEGIN_DRAG event, generated when user
starts resizing a column - can be vetoed.
@event{EVT_PG_COL_DRAGGING,(id, func)}
Respond to wxEVT_PG_COL_DRAGGING, event, generated when a
column resize by user is in progress. This event is also generated
when user double-clicks the splitter in order to recenter
it.
@event{EVT_PG_COL_END_DRAG(id, func)}
Respond to wxEVT_PG_COL_END_DRAG event, generated after column
resize by user has finished.
@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.
