Inheritance diagram for wxQueryLayoutInfoEvent:
[legend]

## Detailed Description

This event is sent when wxLayoutAlgorithm wishes to get the size, orientation and alignment of a window.

More precisely, the event is sent by the OnCalculateLayout handler which is itself invoked by wxLayoutAlgorithm.

## Events using this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxQueryLayoutInfoEvent& event)

Event macros:

- EVT_QUERY_LAYOUT_INFO(func):
  Process a `wxEVT_QUERY_LAYOUT_INFO` event, to get size, orientation and alignment from a window.

Public Member Functions inherited from wxEvent
| wxEvent (int id=0, wxEventType eventType=wxEVT_NULL)
| Constructor.
virtual wxEvent * | Clone () const =0
| Returns a copy of the event.
wxObject * | GetEventObject () const
| Returns the object (usually a window) associated with the event, if any.
wxEventType | GetEventType () const
| Returns the identifier of the given event type, such as `wxEVT_BUTTON`.
virtual wxEventCategory | GetEventCategory () const
| Returns a generic category for this event.
int | GetId () const
| Returns the identifier associated with this event, such as a button command id.
wxObject * | GetEventUserData () const
| Return the user data associated with a dynamically connected event handler.
bool | GetSkipped () const
| Returns true if the event handler should be skipped, false otherwise.
long | GetTimestamp () const
| Gets the timestamp for the event.
bool | IsCommandEvent () const
| Returns true if the event is or is derived from wxCommandEvent else it returns false.
void | ResumePropagation (int propagationLevel)
| Sets the propagation level to the given value (for example returned from an earlier call to wxEvent::StopPropagation).
void | SetEventObject (wxObject *object)
| Sets the originating object.
void | SetEventType (wxEventType type)
| Sets the event type.
void | SetId (int id)
| Sets the identifier associated with this event, such as a button command id.
void | SetTimestamp (long timeStamp=0)
| Sets the timestamp for the event.
bool | ShouldPropagate () const
| Test if this event should be propagated or not, i.e. if the propagation level is currently greater than 0.
void | Skip (bool skip=true)
| This method can be used inside an event handler to control whether further event handlers bound to this event will be called after the current one returns.
int | StopPropagation ()
| Stop the event from propagating to its parent window.

| wxObject ()
| Default ctor; initializes to NULL the internal reference data.
| wxObject (const wxObject &other)
| Copy ctor.
virtual | ~wxObject ()
| Destructor.
virtual wxClassInfo * | GetClassInfo () const
| This virtual function is redefined for every class that requires run-time type information, when using the wxDECLARE_CLASS macro (or similar).

| Returns the wxObject::m_refData pointer, i.e. the data referenced by this object.
bool | IsKindOf (const wxClassInfo *info) const
| Determines whether this class is a subclass of (or the same class as) the given class.
bool | IsSameAs (const wxObject &obj) const

| Makes this object refer to the data in clone.
void | SetRefData (wxObjectRefData *data)
| Sets the wxObject::m_refData pointer.
void | UnRef ()
| Decrements the reference count in the associated data, and if it is zero, deletes the data.
void | UnShare ()
