The
AG_SocketNew() function allocates, initializes, and attaches a new
AG_Socket widget.
The
AG_SocketFromSurface() and
AG_SocketFromBMP() variants also set a background image for the socket, typically used to show
the type of icons that can be drag-and-dropped onto the socket.
Acceptable
flags include:
| AG_SOCKET_STICKY_STATE | Mouse click should toggle the boolean state.
| | AG_SOCKET_HFILL | Expand horizontally in parent container.
| | AG_SOCKET_VFILL | Expand vertically in parent container.
| | AG_SOCKET_EXPAND | Shorthand for
AG_SOCKET_HFILL AG_SOCKET_VFILL|. |
The
AG_SocketInsertFn() function configures a callback routine
fn() that will be invoked whenever the user tries to drop an icon onto the
socket.
A pointer to the socket and the icon being dropped will be passed to that
function.
Typically, this routine will use
AG_SocketInsertIcon() to assign the icon to the socket.
If
fn() returns 1, the drag-and-drop item will be destroyed.
The
AG_SocketRemoveFn() function registers a callback routine that will be invoked before an icon
is removed from a socket.
The
AG_SocketOverlayFn() registers a routine that will be invoked in rendering context to draw items
on top of the socket (and any contained icons).
The
AG_SocketSetPadding() function sets the padding around the socket's icon area in pixels.
AG_SocketBgRect() configures the socket to use a rectangular shape of the given
dimensions in pixels.
AG_SocketBgCircle() arranges for the socket to use a circular shape of the given radius in pixels.
AG_SocketBgPixmap() uses the given surface as background image.
The
AG_SocketBgPixmapNODUP() variant prevents the surface from being copied.
