#include <wx/dataview.h>
This is the event class for the wxDataViewCtrl notifications.
The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

wxDataViewEvent (wxEventType commandType=wxEVT_NULL, int winid=0) | |
Constructor. | |
int | GetColumn () const |
Returns the position of the column in the control or -1 if no column field was set by the event emitter. | |
wxDataViewColumn * | GetDataViewColumn () const |
Returns a pointer to the wxDataViewColumn from which the event was emitted or NULL. | |
wxDataViewModel * | GetModel () const |

Sets the value associated with this event. | |
void | SetDataObject (wxDataObject *obj) |
Set wxDataObject for data transfer within a drag operation. | |
wxDataObject * | GetDataObject () const |
Used internally. | |
void | SetDataFormat (const wxDataFormat &format) |
Used internally. | |
wxDataFormat | GetDataFormat () const |
Gets the wxDataFormat during a drop operation. | |

wxDataViewEvent::wxDataViewEvent | ( | wxEventType | commandType = wxEVT_NULL , |
int | winid = 0 |
||
) |
Constructor.
Typically used by wxWidgets internals only.
int wxDataViewEvent::GetCacheFrom | ( | ) | const |
Return the first row that will be displayed.
int wxDataViewEvent::GetCacheTo | ( | ) | const |
Return the last row that will be displayed.
int wxDataViewEvent::GetColumn | ( | ) | const |
Returns the position of the column in the control or -1 if no column field was set by the event emitter.
void* wxDataViewEvent::GetDataBuffer | ( | ) | const |
Gets the data buffer for a drop data transfer.
wxDataFormat wxDataViewEvent::GetDataFormat | ( | ) | const |
Gets the wxDataFormat during a drop operation.
wxDataObject* wxDataViewEvent::GetDataObject | ( | ) | const |
Used internally.
Gets associated wxDataObject for data transfer within a drag operation.
size_t wxDataViewEvent::GetDataSize | ( | ) | const |
Gets the data size for a drop data transfer.
wxDataViewColumn* wxDataViewEvent::GetDataViewColumn | ( | ) | const |
Returns a pointer to the wxDataViewColumn from which the event was emitted or NULL.
wxDataViewModel* wxDataViewEvent::GetModel | ( | ) | const |
Returns the wxDataViewModel associated with the event.
wxPoint wxDataViewEvent::GetPosition | ( | ) | const |
Returns the position of a context menu event in screen coordinates.
const wxVariant& wxDataViewEvent::GetValue | ( | ) | const |
Returns a reference to a value.
bool wxDataViewEvent::IsEditCancelled | ( | ) | const |
Can be used to determine whether the new value is going to be accepted in wxEVT_COMMAND_DATAVIEW_ITEM_EDITING_DONE handler.
Returns true if editing the item was cancelled or if the user tried to enter an invalid value (refused by wxDataViewRenderer::Validate()). If this method returns false, it means that the value in the model is about to be changed to the new one.
Notice that wxEVT_COMMAND_DATAVIEW_ITEM_EDITING_DONE event handler can call wxNotifyEvent::Veto() to prevent this from happening.
Currently support for setting this field and for vetoing the change is only available in the generic version of wxDataViewCtrl, i.e. under MSW but not GTK nor OS X.
