Detailed Description

Generated during Drag-and-Drop (DND) operations.

get_event_type() will return one of Gdk::Event::Type::DRAG_ENTER, Gdk::Event::Type::DRAG_LEAVE, Gdk::Event::Type::DRAG_MOTION, Gdk::Event::Type::DRAG_STATUS, Gdk::Event::Type::DROP_START or Gdk::Event::Type::DROP_FINISHED.

Since gtkmm 3.90:

Constructor & Destructor Documentation

Gdk::EventDND::EventDND ( )

Creates an invalid event object.

Calling any member functions is undefined behavior.

Gdk::EventDND::EventDND ( GdkEventDND *  gobject,
bool  make_a_copy = false 
)
explicit

Wraps a C event instance.

This constructor either acquires ownership of gobject, or copies it.

Parameters
gobjectEvent to wrap.
make_a_copyIf false, the ownership of gobject is acquired, otherwise, a copy is made.

Member Function Documentation

Glib::RefPtr<Gdk::DragContext> Gdk::EventDND::get_context ( )

Returns the drag context.

Glib::RefPtr<const Gdk::DragContext> Gdk::EventDND::get_context ( ) const
double Gdk::EventDND::get_root_x ( ) const

Returns the X coordinate of the pointer relative to the root screen.

Only meaningful if get_event_type() returns Gdk::Event::Type::DRAG_MOTION or Gdk::Event::Type::DROP_START.

double Gdk::EventDND::get_root_y ( ) const

Returns the Y coordinate of the pointer relative to the root screen.

guint32 Gdk::EventDND::get_time ( ) const

Returns the timestamp of the event in milliseconds.

GdkEventDND* Gdk::EventDND::gobj ( )
inline

Provides access to the underlying C instance.

const GdkEventDND* Gdk::EventDND::gobj ( ) const
inline

Provides access to the underlying C instance.

GdkEventDND* Gdk::EventDND::gobj_copy ( ) const

Provides access to the underlying C instance.

The caller is responsible for freeing it with gdk_event_free(). Use when directly setting fields in structs.

void Gdk::EventDND::swap ( EventDND other)
noexcept

Friends And Related Function Documentation

void swap ( EventDND lhs,
EventDND rhs 
)
related
Parameters
lhsThe left-hand side
rhsThe right-hand side
Gdk::EventDND wrap ( GdkEventDND *  object,
bool  take_copy = false 
)
related

A Glib::wrap() method for this object.

Parameters
objectThe C instance.
take_copyFalse if the result should take ownership of the C instance. True if it should take a new copy.
Returns
A C++ instance that wraps this C instance.
const EventDND& wrap_event ( const GdkEventDND *&  event)
related

Wraps a C event instance without making unnecessary copy when the ownership can not be acquired.

The event pointer must not be deleted until last usage of the returned instance. Note, that this requirement applies to the pointer itself, in addition to the object it is pointing to.
