Detailed Description

Interface for drag surface surfaces.

A Gdk::DragSurface is a surface that is used during a DnD operation.

Since gtkmm 3.98:

Member Function Documentation

static void Gdk::DragSurface::add_interface ( GType  gtype_implementer)
static
static GType Gdk::DragSurface::get_type ( )
static

Get the GType for this class, for use with the underlying GObject type system.

GdkDragSurface* Gdk::DragSurface::gobj ( )
inline

Provides access to the underlying C GObject.

const GdkDragSurface* Gdk::DragSurface::gobj ( ) const
inline

Provides access to the underlying C GObject.

DragSurface& Gdk::DragSurface::operator= ( DragSurface&&  src)
noexcept
bool Gdk::DragSurface::present ( int  width,
int  height 
)

Present drag_surface.

Parameters
widthThe unconstrained drag_surface width to layout.
heightThe unconstrained drag_surface height to layout.
Returns
false if it failed to be presented, otherwise true.

Glib::RefPtr< Gdk::DragSurface > wrap ( GdkDragSurface *  object,
bool  take_copy = false 
)

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 or ref.
Returns
A C++ instance that wraps this C instance.
