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_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.

    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):

Constructor & Destructor Documentation

◆ wxRichTextEvent() [1/2]

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

Constructor.

Parameters
commandTypeThe type of the event.
winidWindow identifier. The value wxID_ANY indicates a default value.

◆ wxRichTextEvent() [2/2]

wxRichTextEvent::wxRichTextEvent ( const wxRichTextEvent event)

Copy constructor.

Member Function Documentation

◆ Clone()

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); }
An event is a structure holding information about an event passed to a callback or member function.
Definition: event.h:93
virtual wxEvent * Clone() const
Returns a copy of the event.

◆ GetOldContainer()

wxRichTextParagraphLayoutBox* wxRichTextEvent::GetOldContainer ( ) const

Returns the old container, for a focus change event.
