## Detailed Description

This is the event class for wxRichTextCtrl notifications.

## Events using this class

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

void handlerFuncName(wxRichTextEvent& event)

Event macros:

- EVT_RICHTEXT_LEFT_CLICK(id, func):
  Process a `wxEVT_RICHTEXT_LEFT_CLICK` event, generated when the user releases the left mouse button over an object.
- EVT_RICHTEXT_RIGHT_CLICK(id, func):
  Process a `wxEVT_RICHTEXT_RIGHT_CLICK` event, generated when the user releases the right mouse button over an object.
- EVT_RICHTEXT_MIDDLE_CLICK(id, func):
  Process a `wxEVT_RICHTEXT_MIDDLE_CLICK` event, generated when the user releases the middle mouse button over an object.
- EVT_RICHTEXT_LEFT_DCLICK(id, func):
  Process a `wxEVT_RICHTEXT_LEFT_DCLICK` event, generated when the user double-clicks an object.
- EVT_RICHTEXT_RETURN(id, func):
  Process a `wxEVT_RICHTEXT_RETURN` event, generated when the user presses the return key. Valid event functions: GetFlags, GetPosition.
- EVT_RICHTEXT_CHARACTER(id, func):
  Process a `wxEVT_RICHTEXT_CHARACTER` event, generated when the user presses a character key. Valid event functions: GetFlags, GetPosition, GetCharacter.
- EVT_RICHTEXT_CONSUMING_CHARACTER(id, func):
  Process a `wxEVT_RICHTEXT_CONSUMING_CHARACTER` event, generated when the user presses a character key but before it is processed and inserted into the control. Call Veto to prevent normal processing. Valid event functions: GetFlags, GetPosition, GetCharacter, Veto.
- EVT_RICHTEXT_DELETE(id, func):
  Process a `wxEVT_RICHTEXT_DELETE` event, generated when the user presses the backspace or delete key. Valid event functions: GetFlags, GetPosition.
- EVT_RICHTEXT_RETURN(id, func):
  Process a `wxEVT_RICHTEXT_RETURN` event, generated when the user presses the return key. Valid event functions: GetFlags, GetPosition.
- EVT_RICHTEXT_STYLE_CHANGED(id, func):
  Process a `wxEVT_RICHTEXT_STYLE_CHANGED` event, generated when styling has been applied to the control. Valid event functions: GetPosition, GetRange.
- EVT_RICHTEXT_STYLESHEET_CHANGED(id, func):
  Process a `wxEVT_RICHTEXT_STYLESHEET_CHANGING` event, generated when the control's stylesheet has changed, for example the user added, edited or deleted a style. Valid event functions: GetRange, GetPosition.
- EVT_RICHTEXT_STYLESHEET_REPLACING(id, func):
  Process a `wxEVT_RICHTEXT_STYLESHEET_REPLACING` event, generated when the control's stylesheet is about to be replaced, for example when a file is loaded into the control. Valid event functions: Veto, GetOldStyleSheet, GetNewStyleSheet.
- EVT_RICHTEXT_STYLESHEET_REPLACED(id, func):
  Process a `wxEVT_RICHTEXT_STYLESHEET_REPLACED` event, generated when the control's stylesheet has been replaced, for example when a file is loaded into the control. Valid event functions: GetOldStyleSheet, GetNewStyleSheet.
- EVT_RICHTEXT_PROPERTIES_CHANGED(id, func):
  Process a `wxEVT_RICHTEXT_PROPERTIES_CHANGED` event, generated when properties have been applied to the control. Valid event functions: GetPosition, GetRange.
- EVT_RICHTEXT_CONTENT_INSERTED(id, func):
  Process a `wxEVT_RICHTEXT_CONTENT_INSERTED` event, generated when content has been inserted into the control. Valid event functions: GetPosition, GetRange.
- EVT_RICHTEXT_CONTENT_DELETED(id, func):
  Process a `wxEVT_RICHTEXT_CONTENT_DELETED` event, generated when content has been deleted from the control. Valid event functions: GetPosition, GetRange.
- EVT_RICHTEXT_BUFFER_RESET(id, func):
  Process a `wxEVT_RICHTEXT_BUFFER_RESET` event, generated when the buffer has been reset by deleting all content. You can use this to set a default style for the first new paragraph.
- EVT_RICHTEXT_SELECTION_CHANGED(id, func):
  Process a `wxEVT_RICHTEXT_SELECTION_CHANGED` event, generated when the selection range has changed.
- EVT_RICHTEXT_FOCUS_OBJECT_CHANGED(id, func):

## Constructor & Destructor Documentation

wxRichTextEvent::wxRichTextEvent | ( | wxEventType | commandType = `wxEVT_NULL`,
|  | int | winid = `0`
| ) |  |

Constructor.

Parameters

  commandType | The type of the event.
  winid | Window identifier. The value `wxID_ANY` indicates a default value.

wxRichTextEvent::wxRichTextEvent | ( | const wxRichTextEvent & | event | ) |

Copy constructor.

## Member Function Documentation

virtual wxEvent* wxRichTextEvent::Clone | ( |  | ) | const

virtual

Returns a copy of the event.

Any event that is posted to the wxWidgets event system for later action (via wxEvtHandler::AddPendingEvent, wxEvtHandler::QueueEvent or wxPostEvent()) must implement this method.

All wxWidgets events fully implement this method, but any derived events implemented by the user should also implement this method just in case they (or some event derived from them) are ever posted.

All wxWidgets events implement a copy constructor, so the easiest way of implementing the Clone function is to implement a copy constructor for a new event (call it MyEvent) and then define the Clone function like this:

wxEvent *Clone() const { return new MyEvent(*this); }

Implements wxEvent.

Returns the old container, for a focus change event.
