wxEvtHandler

Implements methods from the following classes

• wxObject

Methods

• wxEvtHandler
  Constructor.
• AddPendingEvent
  Post an event to be processed later.
• Connect
  Connects the given function dynamically with the event handler, id and event type.
• DeletePendingEvents
  Deletes all events queued on this event handler using QueueEvent() or AddPendingEvent().
• GetEvtHandlerEnabled
  Returns true if the event handler is enabled, false otherwise.
• GetNextHandler
  Returns the pointer to the next handler in the chain.
• GetPreviousHandler
  Returns the pointer to the previous handler in the chain.
• IsUnlinked
  Returns true if the next and the previous handler pointers of this event handler instance are NULL.
• ProcessEvent
  Processes an event, searching event tables and calling zero or more suitable event handler function(s).
• ProcessEventLocally
  Try to process the event in this handler and all those chained to it.
• ProcessPendingEvents
  Processes the pending events previously queued using QueueEvent() or AddPendingEvent(); you must call this function only if you are sure there are pending events for this handler, otherwise a wxCHECK will fail.
• QueueEvent
  Queue event for a later processing.
• SafelyProcessEvent
  Processes an event by calling ProcessEvent() and handles any exceptions that occur in the process.
• SetEvtHandlerEnabled
  Enables or disables the event handler.
• SetNextHandler
  Sets the pointer to the next handler.
• SetPreviousHandler
  Sets the pointer to the previous handler.
• TryAfter
  Method called by ProcessEvent() as last resort.
• TryBefore
  Method called by ProcessEvent() before examining this object event tables.
• Unlink
  Unlinks this event handler from the chain it's part of (if any); then links the "previous" event handler to the "next" one (so that the chain won't be interrupted).

Static Methods

• AddFilter
  Add an event filter whose FilterEvent() method will be called for each and every event processed by wxWidgets.
• RemoveFilter
  Remove a filter previously installed with AddFilter().

wxEvtHandler

wxEvtHandler ( )

Constructor.

AddFilter

static AddFilter ( wxEventFilter &$filter )

Add an event filter whose FilterEvent() method will be called for each and every event processed by wxWidgets.

AddPendingEvent

AddPendingEvent ( wxEvent $event )

Post an event to be processed later.

Connect

Connect ( integer $id, integer $lastId, integer $eventType, , wxObject &$userData=NULL, wxEvtHandler &$eventSink=NULL )

Connects the given function dynamically with the event handler, id and event type.

DeletePendingEvents

DeletePendingEvents ( )

Deletes all events queued on this event handler using QueueEvent() or AddPendingEvent().

GetEvtHandlerEnabled

bool GetEvtHandlerEnabled ( )

Returns true if the event handler is enabled, false otherwise.

GetNextHandler

wxEvtHandler& GetNextHandler ( )

Returns the pointer to the next handler in the chain.

GetPreviousHandler

wxEvtHandler& GetPreviousHandler ( )

Returns the pointer to the previous handler in the chain.

IsUnlinked

bool IsUnlinked ( )

Returns true if the next and the previous handler pointers of this event handler instance are NULL.

ProcessEvent

bool ProcessEvent ( wxEvent &$event )

Processes an event, searching event tables and calling zero or more suitable event handler function(s).

ProcessEventLocally

bool ProcessEventLocally ( wxEvent &$event )

Try to process the event in this handler and all those chained to it.

ProcessPendingEvents

ProcessPendingEvents ( )

Processes the pending events previously queued using QueueEvent() or AddPendingEvent(); you must call this function only if you are sure there are pending events for this handler, otherwise a wxCHECK will fail.

QueueEvent

QueueEvent ( wxEvent &$event )

Queue event for a later processing.

RemoveFilter

static RemoveFilter ( wxEventFilter &$filter )

Remove a filter previously installed with AddFilter().

SafelyProcessEvent

bool SafelyProcessEvent ( wxEvent &$event )

SetEvtHandlerEnabled

SetEvtHandlerEnabled ( bool $enabled )

Enables or disables the event handler.

SetNextHandler

SetNextHandler ( wxEvtHandler &$handler )

Sets the pointer to the next handler.

SetPreviousHandler

SetPreviousHandler ( wxEvtHandler &$handler )

TryAfter

bool TryAfter ( wxEvent &$event )

Method called by ProcessEvent() as last resort.

TryBefore

bool TryBefore ( wxEvent &$event )

Method called by ProcessEvent() before examining this object event tables.

Unlink

Unlink ( )

Unlinks this event handler from the chain it's part of (if any); then links the "previous" event handler to the "next" one (so that the chain won't be interrupted).
