|
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.
|
|
|
|
@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 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.

possible moment.
