14 \anchor dependency_tree_general_description_anchor <h2>General description</h2>
16 You can display the ascendants and descendants of object(s) in a tree structure to better understand the relations between the %GEOM
19 To build the dependency tree, select the necessary object or objects (multiple
20 selection is supported) in the Object Browser or OCC Viewer and call "Show dependency tree" context menu item.
22 \image html tree_example.png
25 "Dependency Tree" view window will display the dependency tree for the selected object.
26 It is also possible to select an object(s) directly in the "Dependency Tree" view and to rebuild the tree by selecting
27 "Rebuild the tree" context menu item.
29 All necessary parameters of Dependency Tree Viewer can be edited in the \ref pref_dependency_tree "Preferences".
32 \anchor dependency_tree_nodes_anchor <h2>Nodes</h2>
34 Tree nodes in the Dependency Viewer are named according to the study
35 names of the corresponding objects.
37 All nodes have fixed size, so long names are cut; the full object name can be seen in the tooltip
38 when the cursor is hovered over the node.
40 "Dependency Tree" view supports the following states of nodes:
42 <ul><li><b>Main node</b> - corresponds to the main object(s) selected in Object
43 Browser, OCC Viewer or Dependency Tree Viewer;</li></ul>
44 \image html tree_main_node.png
46 <ul><li><b>Default node</b> - ascendant or descendant node of the dependency tree corresponding to an object published in the study;</li></ul>
47 \image html tree_default_node.png
49 <ul><li><b>Unpublished node</b> - corresponds to an object that was not published in the study;</li></ul>
50 \image html tree_unpublished_node.png
52 <ul><li><b>Highlighted node</b> - the state of a node when the mouse cursor is hovered over it;</li></ul>
53 \image html tree_highlighted_node.png
55 <ul><li><b>Selected node</b> - the state of node when the user clicks the left mouse button it.</li></ul>
56 \image html tree_selected_node.png
59 \anchor dependency_tree_links_anchor <h2>Links</h2>
61 Dependency Tree Viewer shows oriented links between nodes to
62 represent the dependency direction. The viewer supports the following states of links:
64 <ul><li><b>Unidirectional link</b> - shows that object B depends on object A;</li></ul>
65 \image html tree_unidir_link.png
67 <ul><li><b>Bidirectional link</b> - shows that object B depends on
68 object A and, at the same time, object A depends on object B;</li></ul>
69 \image html tree_bidir_link.png
71 <ul><li><b>Self-dependency link</b> - shows that an object depends on itself;</li></ul>
72 \image html tree_selfdep_link.png
74 <ul><li><b>Cyclic dependency links</b> - shows cyclic dependency of some nodes.</li></ul>
75 \image html tree_cycldep_link.png
78 \anchor dependency_tree_operations_anchor <h2>Viewer Operations</h2>
80 The dependency tree of a chosen %GEOM object is displayed in
81 the dedicated 2D view window.
82 \n The functionalities of 2D viewer are available via its Viewer
85 Buttons marked with small downward triangles have extended
86 functionality which can be accessed by locking on them with left
91 <b>Dump View</b> - exports the current scene in bmp, png or jpeg image format.
92 \image html tree_view_dump.png
94 <b>Fit all</b> - scales the presentation so that it could fit within
95 the Viewer boundaries.
96 \image html tree_view_fitall.png
98 <b>Fit area</b> - resizes the view to place in the visible area only
99 the contents of a frame drawn with pressed left mouse button.
100 \image html tree_view_fitarea.png
102 <b>Fit selection</b> - resizes the view to fit in the visible area
103 only currently selected objects.
104 \image html tree_view_fitselect.png
106 <b>Zoom</b> - allows to zoom in and out.
107 \image html tree_view_zoom.png
109 <b>Panning</b> - if the represented objects are greater that the
110 visible area and you don't wish to use <b>Fit all</b> functionality,
111 click on this button and you'll be able to drag the scene to see its
113 \image html tree_view_pan.png
115 <b>Global panning</b> - allows to select a point to be the center of
116 the presentation showing all displayed objects in the visible ares.
117 \image html tree_view_glpan.png
119 <b>Hierarchy depth</b> - allows to change the number of hierarchy
120 levels to be shown in the dependency tree.
121 \image html tree_hierarchy_type.png
123 <li>Level 1 corresponds to the parents and children of the selected
125 <li>Level 2 adds the grand-parents and grand-children
126 of the selected object(s);</li>
130 <b>Display ascendants</b> - allows showing/hiding the ascendants.
131 \image html tree_disp_ascendants.png
133 <b>Display descendants</b> - allows showing/hiding the descendants.

136 <b>Move nodes</b> -if checked, it is possible to move nodes in the viewer.
137 \image html tree_move_nodes.png
139 <b>Update</b> - updates the dependency tree view, reflecting changes introduced in the hierarchy.
