Additional arguments

 

gdl_dock_object_bind ()

void
gdl_dock_object_bind (GdlDockObject *object,
                      GObject *master);

Add a link between a GdlDockObject and a master. It is normally not used directly because it is automatically called when a new object is docked.

Parameters

object

A GdlDockObject

 

master

A GdlDockMaster

 

gdl_dock_object_child_placement ()

gboolean
gdl_dock_object_child_placement (GdlDockObject *object,

                                 GdlDockPlacement *placement);

This function returns information about placement of a child dock object inside another dock object. The function returns TRUE if child is effectively a child of object . placement should normally be initially setup to GDL_DOCK_NONE. If it's set to some other value, this function will not touch the stored value if the specified placement is "compatible" with the actual placement of the child.

placement can be NULL, in which case the function simply tells if child is attached to object .

Parameters

object

the dock object we are asking for child placement

 

child

the child of the object we want the placement for

 

placement

where to return the placement information.

[allow-none]

Returns

TRUE if child is a child of object .
