When you copy and paste or drag and drop a global object onto a standard graphic display, the resulting reference object has several new properties called Link properties.
The Link properties are given default values when the reference object is created. You can change the default values that are assigned to a new reference object by setting the global object defaults.
The new default values will be applied to all new reference objects, as they are created. The values of the properties can be changed at the reference object if required.
The LinkAnimation property determines whether or not the animation assigned to a base object will be used by the reference object, and if the animation is used, whether or not the expressions assigned to the base object are used. The initial default value of this property is Link without expressions.
The number of tags used by the reference object's expressions will count toward the 1000 tag limit for the display that the reference object is on.
When the default value is Do not link, all animation settings for the reference object can be edited. Changes to the base object's animation will not be reflected in the reference object.
When the default value is Link with expressions, the animation for the reference object cannot be edited and the items on the Animation menu will be unavailable. Changes to the base object's animation will be reflected in the reference object.
When the default value is Link without expressions, the expressions and the expression range settings used by animation for the reference object can be edited. Changes to the reference object's expressions will not be reflected in the base object.
All other settings for animation of the reference object (for example, color settings in color animation) will not be editable, and any changes to these settings in the base object will be reflected in the reference object.
The LinkConnections property determines whether the connections assigned to the base object will be used by the reference object. The initial default value of this property is False.
The number of tags used by the reference object's expressions will count toward the 1000 tag limit for the display that the reference object is on.
When the default value is set to True, the reference object's connections cannot be edited, and the reference object will use the base object's connection assignments.
When the default value is set to False, the reference object's connections will be read/write and can be edited. Changes to the connections on the reference object will not be reflected in the base object, and changes made to the connections on the base objects will not be reflected on the reference object.
The LinkSize property determines whether the values assigned to the Height and Width properties of base objects will be used by the reference object. The initial default value of this property is True.
When the default value is set to True, the reference object's Height and Width properties will be read-only, and the base object's values for these properties will be used. If you resize the object using its handles, it will snap back to its original size.
When the default value is set to False, the reference objects Height and Width properties can be edited. Changes made to these properties on the base object will not be reflected on the reference object.
