wxClipboardTextEvent Class Reference
#include <wx/event.h>
Inheritance diagram for wxClipboardTextEvent:
Detailed Description
This class represents the events generated by a control (typically a wxTextCtrl but other windows can generate these events as well) when its content gets copied or cut to, or pasted from the clipboard.
There are three types of corresponding events wxEVT_TEXT_COPY, wxEVT_TEXT_CUT and wxEVT_TEXT_PASTE.
If any of these events is processed (without being skipped) by an event handler, the corresponding operation doesn't take place which allows to prevent the text from being copied from or pasted to a control. It is also possible to examine the clipboard contents in the PASTE event handler and transform it in some way before inserting in a control – for example, changing its case or removing invalid characters.
Finally notice that a CUT event is always preceded by the COPY event which makes it possible to only process the latter if it doesn't matter if the text was copied or cut.
- Note
- These events are currently only generated by wxTextCtrl in wxGTK and wxOSX but are also generated by wxComboBox without wxCB_READONLY style in wxMSW.
Events using this class
The following event handler macros redirect the events to member function handlers 'func' with prototypes like:
void handlerFuncName(wxClipboardTextEvent& event)
Event macros:
- EVT_TEXT_COPY(id, func):Some or all of the controls content was copied to the clipboard.
- EVT_TEXT_CUT(id, func):Some or all of the controls content was cut (i.e. copied and deleted).
- EVT_TEXT_PASTE(id, func):Clipboard content was pasted into the control.

| wxCommandEvent (wxEventType commandEventType=wxEVT_NULL, int id=0) | |
| Constructor. | |
| void * | GetClientData () const |
| Returns client data pointer for a listbox or choice selection event (not valid for a deselection). | |
| wxClientData * | GetClientObject () const |
| Returns client object pointer for a listbox or choice selection event (not valid for a deselection). | |
| long | GetExtraLong () const |
| Returns extra information dependent on the event objects type. | |
| int | GetInt () const |
| Returns the integer identifier corresponding to a listbox, choice or radiobox selection (only if the event was a selection, not a deselection), or a boolean value representing the value of a checkbox. | |
| int | GetSelection () const |
| Returns item index for a listbox or choice selection event (not valid for a deselection). | |
| wxString | GetString () const |
| Returns item string for a listbox or choice selection event. | |
| bool | IsChecked () const |
| This method can be used with checkbox and menu events: for the checkboxes, the method returns true for a selection event and false for a deselection one. | |
| bool | IsSelection () const |
| For a listbox or similar event, returns true if it is a selection, false if it is a deselection. | |
| void | SetClientData (void *clientData) |
| Sets the client data for this event. | |
| void | SetClientObject (wxClientData *clientObject) |
| Sets the client object for this event. | |
| void | SetExtraLong (long extraLong) |
| Sets the m_extraLong member. | |
| void | SetInt (int intCommand) |
| Sets the m_commandInt member. | |
| void | SetString (const wxString &string) |
| Sets the m_commandString member. | |
| 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. | |
| Public Member Functions inherited from wxObject | |
| 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). | |
| wxObjectRefData * | GetRefData () const |
| 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 |
| Returns true if this object has the same data pointer as obj. | |
| void | Ref (const wxObject &clone) |
| 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 () |
| This is the same of AllocExclusive() but this method is public. | |
| void | operator delete (void *buf) |
The delete operator is defined for debugging versions of the library only, when the identifier WXDEBUG is defined. | |
| void * | operator new (size_t size, const wxString &filename=NULL, int lineNum=0) |
The new operator is defined for debugging versions of the library only, when the identifier WXDEBUG is defined. | |
