DragSurface
- class DragSurface(*args, **kwargs)
A GdkDragSurface
is an interface for surfaces used during DND.
Methods
Signals
- class DragSurface.signals
- compute_size(size: DragSurfaceSize) None
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
DragSurfaceSize
object that is passed to the signal handler, usingset_size
.Failing to set a size so will result in an arbitrary size being used as a result.
Added in version 4.12.
- Parameters:
size – the size of the drag surface
