To give the user of a computer system flexibility in generating displays of object trees, a user may initially select an object (see fig 5 not shown) appearing in a default tree display. A filter dialog box is summoned to allow the user to define custom object filters 98 or to select one of several predefined tree-level filters 96. The criteria associated with a selected filter are identified and retrieved and applied to all nodes (60a, 60b, 60c) on branches that are at levels subordinate to the level of the initially selected node (59). Once all of the relevant nodes (60a, 60b, 60c) are tested, a new tree display is generated which retains the tree structure but which shows only those nodes (64, 66, 68) which meet the selection criteria.
