Molecule Link

Link a molecule or a list of 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 class menu shows the classes of objects that can be owned by molecules. Pressing the button Above, the same menu shows the classes of objects that can own molecules.

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. Pressing the List button, the current list of molecules 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 molecules: Object.

The Object method links a molecule or a list of molecules to a single object, Above or Below.

When the Hierarchy is Above, the molecule is unlinked from its current parent and linked to the new object. When the molecule 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 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.

When linking a list of molecules Above, all molecules in the list are unlinked and linked to the parent object. When linking a list of molecules Below, the child object is replicated as many times as necessary to link each molecule in the list to a different replica.
