## Detailed Description

Event generated by wxTreeListCtrl.

Category: Controls, Events

Since
  2.9.3

## Public Member Functions
| wxTreeListEvent ()
wxTreeListItem | GetItem () const
| Return the item affected by the event.
wxCheckBoxState | GetOldCheckedState () const
| Return the previous state of the item checkbox.
unsigned | GetColumn () const
| Return the column affected by the event.
Public Member Functions inherited from wxNotifyEvent
| wxNotifyEvent (wxEventType eventType=wxEVT_NULL, int id=0)
| Constructor (used internally by wxWidgets only).
void | Allow ()
| This is the opposite of Veto(): it explicitly allows the event to be processed.
bool | IsAllowed () const
| Returns true if the change is allowed (Veto() hasn't been called) or false otherwise (if it was).
void | Veto ()
| Prevents the change announced by this event from happening.
Public Member Functions inherited from wxCommandEvent
| 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.

## Additional Inherited Members
Protected Member Functions inherited from wxObject
void | AllocExclusive ()
| Ensure that this object's data is not shared with any other object.

| Creates a new instance of the wxObjectRefData-derived class specific to this object and returns it.
virtual wxObjectRefData * | CloneRefData (const wxObjectRefData *data) const
| Creates a new instance of the wxObjectRefData-derived class specific to this object and initializes it copying data.
Protected Attributes inherited from wxEvent

| Indicates how many levels the event can propagate.
Protected Attributes inherited from wxObject
wxObjectRefData * | m_refData
| Pointer to an object which is the object's reference-counted data.

## Constructor & Destructor Documentation

## ◆ wxTreeListEvent()

wxTreeListEvent::wxTreeListEvent | ( |  | ) |

## Member Function Documentation

## ◆ GetColumn()

unsigned wxTreeListEvent::GetColumn | ( |  | ) | const

Return the column affected by the event.

This is currently only used with `wxEVT_TREELIST_COLUMN_SORTED` event.

## ◆ GetItem()

wxTreeListItem wxTreeListEvent::GetItem | ( |  | ) | const

Return the item affected by the event.

This is the item being selected, expanded, checked or activated (depending on the event type).

## ◆ GetOldCheckedState()

wxCheckBoxState wxTreeListEvent::GetOldCheckedState | ( |  | ) | const

Return the previous state of the item checkbox.

This method can be used with `wxEVT_TREELIST_ITEM_CHECKED` events only.

Notice that the new state of the item can be retrieved using wxTreeListCtrl::GetCheckedState().
