Vadim Zeitlin ce00f59b5b No changes whatsoever, just remove trailing whitespace. 
There are no real changes in this commit but it removes all trailing white
space from our source files. This avoids problems when applying patches and
making diffs and it would be nice to prevent it from reappearing.

/** @class wxPropertyGrid
wxPropertyGrid is a specialized grid for editing properties
such as strings, numbers, flagsets, fonts, and colours. wxPropertySheet
used to do the very same thing, but it hasn't been updated for a while
and it is currently deprecated.
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 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_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..
@event{EVT_PG_LABEL_EDIT_BEGIN(id, func)}
Respond to wxEVT_PG_LABEL_EDIT_BEGIN event, generated when 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 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.
