Link molecules to other objects.
Hierarchy
Molecules can be linked to objects above or below, in the Gamgi
hierarchy. Pressing the button
Below (the default), the
Objects menu shows the classes of objects that can be owned
by molecules: Group, Plane, Direction, Atom (the default), Orbital
and Text. Pressing the button
Above, the same menu shows
the classes of objects that can own molecules: Layer (the default),
Assembly, Cell and Cluster.
Object
Gamgi expects users to identify first the molecule or list of molecules
and then the object to link. When the
Molecule entry is active
and empty, clicking the mouse over a molecule, on the current layer
(local selection), its identification is transported to the
Molecule
entry. Gamgi is now expecting users to click on a object of the
class currently selected in the
Object menu. This object
can be in a different layer or even in a different window (global
selection).
To select a visible object in a different layer, in the same window,
just press the mouse over the object, as if it was in the current
layer. To select objects without visual representation, 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. To select an object in a different window,
with the mouse, use exactly the same procedure, in that window.
Method
Gamgi suppports only one type of linking mode for Molecule:
Object.
The
Object method links a molecule to a single
Object.
When the
Hierarchy is
Above, the molecule is unlinked
from its current parent and linked to the object. When the molecule
is moved to a different layer, all its bonds to other objects are
automatically removed. When the
Hierarchy is
Below,
the object is unlinked from its current parent and linked to the
molecule. 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.
