Tool viewer


Update the list of global images and arrays kept by the Viewer tool


Synopsis
updatedatasets()


Returns
none


Description

This function is quite specific in its use. Its purpose is to search for global Glish symbols which are either Glish arrays or Image tools, and to store them in an internal list. This list is used by other Viewer tool functions. After creating the updated list, it emits an event called 'datasets_updated' so that any interested parties are informed that new data might be available for their own lists. For example, the Viewerdatamanager tool listens for this event so that its list of data remains current. This function might also be used by a programmer after a global Image tool is explicitly constructed in their code.
