Class Details¶

class Gdk.DragSurface¶

Bases:: GObject.GInterface
Structure:: Gdk.DragSurfaceInterface

A GdkDragSurface is an interface for surfaces used during DND.

present(width, height)[source]¶

Parameters:

width (int) – the unconstrained drag_surface width to layout
height (int) – the unconstrained drag_surface height to layout

Returns:

False if it failed to be presented, otherwise True.

Return type:

bool

Present self.

Signal Details¶

Gdk.DragSurface.signals.compute_size(drag_surface, size)¶

Signal Name:

compute-size

Flags:

RUN_LAST

Parameters:

drag_surface (Gdk.DragSurface) – The object which received the signal
size (Gdk.DragSurfaceSize) – the size of the drag surface

Emitted when the size for the surface needs to be computed, when it is present.

This signal will normally be emitted during the native surface layout cycle when the surface size needs to be recomputed.

It is the responsibility of the drag surface user to handle this signal and compute the desired size of the surface, storing the computed size in the [struct`Gdk`.DragSurfaceSize] object that is passed to the signal handler, using [method`Gdk`.DragSurfaceSize.set_size].

Failing to set a size so will result in an arbitrary size being used as a result.
