Atom Link

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.
