Link an atom or a list of atoms to other objects.
Hierarchy
Atoms can be linked to objects above or below, in the Gamgi hierarchy.
Pressing the button
Below (the default), the class menu
shows the classes of objects that can be owned by atoms. Pressing the
button
Above, the same menu shows the classes of objects that
can own atoms.
Gamgi expects users to identify first the atom or list of atoms
and then the object to link. When the
Atom entry is active
and empty, clicking the mouse over an atom, on the current layer
(local selection), its identification is transported to the
Atom
entry. Pressing the
List button, the current list of atoms
is selected instead.
Gamgi is now expecting users to click on a object of the class
currently selected in the class menu. This object can be in
a different layer or window (global selection).
To select a visible object, just press the mouse over the object,
in its window. To select objects without visual representation, such
as layers and lights, press the mouse over the graphic area in the window,
to create a menu with all the objects of that class in the window,
which can then be selected.
Method
Gamgi suppports only one method to link atoms:
Object.
The
Object method links an atom or a list of atoms to a single
object,
Above or
Below.
When linking an atom and the
Hierarchy is
Above, the atom
is unlinked from its current parent and linked to the new object. When
the atom is moved to a different layer, its bonds are automatically removed.
When the
Hierarchy is
Below, the child object is
unlinked from its current parent and linked to the atom. An error
is issued when the parent already owned the child object.
After the linking operation, Gamgi always puts on top
the window and layer containing the linked objects.
When linking a list of atoms
Above, all atoms in the list
are unlinked and linked to the parent object. When linking a list
of atoms
Below, the child object is replicated as many times
as necessary to link each atom in the list to a different replica.
