tmplDragSurfaceT()

A gdk.drag_surface.DragSurface is an interface for surfaces used during DND.

Functions

bool present(int width, int height)

Present drag_surface.

`width`	the unconstrained drag_surface width to layout
`height`	the unconstrained drag_surface height to layout

false if it failed to be presented, otherwise true.

gulong connectComputeSize(T)(T callback, Flag!"After" after = No.After) if (isCallable!T && is(ReturnType!T == void) && (Parameters!T.length < 1 || (ParameterStorageClassTuple!T[0] == ParameterStorageClass.none && is(Parameters!T[0] == gdk.drag_surface_size.DragSurfaceSize))) && (Parameters!T.length < 2 || (ParameterStorageClassTuple!T[1] == ParameterStorageClass.none && is(Parameters!T[1] : gdk.drag_surface.DragSurface))) && Parameters!T.length < 3)

Connect to ComputeSize signal.

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 gdk.drag_surface_size.DragSurfaceSize object that is passed to the signal handler, using gdk.drag_surface_size.DragSurfaceSize.setSize.

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

`callback`	signal callback delegate or function to connect `void callback(gdk.drag_surface_size.DragSurfaceSize size, gdk.drag_surface.DragSurface dragSurface)` `size` the size of the drag surface (optional) `dragSurface` the instance the signal is connected to (optional)
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)
