44 class InteractiveContext from AIS inherits TShared from MMgt
46 ---Purpose: The Interactive Context allows you to manage
47 -- graphic behavior and selection of Interactive Objects
48 -- in one or more viewers. Class methods make this
49 -- highly transparent.
50 -- It is essential to remember that an Interactive Object
51 -- which is already known by the Interactive Context
52 -- must be modified using Context methods. You can
53 -- only directly call the methods available for an
54 -- Interactive Object if it has not been loaded into an
55 -- Interactive Context.
56 -- You must distinguish two states in the Interactive Context:
57 -- - No Open Local Context, also known as the Neutral Point.
58 -- - One or several open local contexts, each
59 -- representing a temporary state of selection and presentation.
60 -- Some methods can only be used in open Local
61 -- Context; others in closed Local Context; others do
62 -- not have the same behavior in one state as in the other.
63 -- The possiblities of use for local contexts are
64 -- numerous depending on the type of operation that
65 -- you want to perform, for example:
66 -- - working on all visualized interactive objects,
67 -- - working on only a few objects,
68 -- - working on a single object.
69 -- 1. When you want ot work on one type of entity, you
70 -- should open a local context with the option
71 -- UseDisplayedObjects set to false. DisplayedObjects
72 -- allows you to recover the visualized Interactive
73 -- Objects which have a given Type and
74 -- Signature from Neutral Point.
75 -- 2. You must keep in mind the fact that when you open
76 -- a Local Context with default options:
77 -- - The Interactive Objects visualized at Neutral Point
78 -- are activated with their default selection mode. You
79 -- must deactivate those which you do not want ot use.
80 -- - The Shape type Interactive Objects are
81 -- automatically decomposed into sub-shapes when
82 -- standard activation modes are launched.
83 -- - The "temporary" Interactive Objects present in the
84 -- Local Contexts are not automatically taken into
85 -- account. You have to load them manually if you
87 -- - The stages could be the following:
88 -- - Open a Local Context with the right options;
89 -- - Load/Visualize the required complementary
90 -- objects with the desired activation modes.
91 -- - Activate Standard modes if necessary
92 -- - Create its filters and add them to the Local Context
93 -- - Detect/Select/recover the desired entities
94 -- - Close the Local Context with the adequate index.
95 -- - It is useful to create an interactive editor, to which
96 -- you pass the Interactive Context. This will take care
97 -- of setting up the different contexts of
98 -- selection/presentation according to the operation
99 -- which you want to perform.

162 Display(me : mutable;
163 anIobj : InteractiveObject from AIS;

165 ---Purpose: Controls the choice between the using the display
166 -- and selection modes of open local context which you
167 -- have defined and activating those available by default.
168 -- If a local context is open and if updateviewer equals
169 -- Standard_False, the Interactive Object anIobj is
170 -- displayed in the default active mode. This will be the
171 -- object's default display mode, if there is one.
172 -- Otherwise, it will be the context mode. The Interactive
173 -- Object's default selection mode is activated. In
174 -- general, this is 0.
175 -- This syntax has the same behavior as local context,
176 -- open or closed. If you want to view the object in open
177 -- local context without selection, use the syntax below,
178 -- setting aSelectionMode to -1.

186 ---Purpose: Controls the choice between the using the display
187 -- and selection modes of open local context which you
188 -- have defined and activating those available by default.
189 -- If no Local Context is opened. and the Interactive
190 -- Object aniobj has no display mode of its own, the
191 -- default display mode, 0, is used. Likewise, if aniobj
192 -- has no selection mode of its own, the default one, 0, is used.
193 -- If a local context is open and if updateviewer equals
194 -- Standard_False, the presentation of the Interactive
195 -- Object activates the selection mode; the object is
196 -- displayed but no viewer will be updated.
197 -- If aSelectionMode equals -1, anIobj will not be
198 -- activated: it will be displayed but will not be selectable.
199 -- Use this if you want to view the object in open local
200 -- context without selection. Note: This option is only
201 -- available in Local Context.
202 -- If allowDecomposition equals true, anIObj can have
203 -- subshapes detected by selection mechanisms. anIObj
204 -- must be able to give a shape selection modes which
205 -- fit the AIS_Shape selection modes:
211 aniobj : InteractiveObject from AIS;
212 SelectionMode : Integer from Standard = -1;
213 AllowDecomp : Boolean from Standard = Standard_False);
214 ---Purpose: Allows you to load the Interactive Object aniobj
215 -- with a given selection mode SelectionMode, and/or
216 -- with the desired decomposition option, whether the
217 -- object is visualized or not. If AllowDecomp =
218 -- Standard_True and, if the interactive object is of
219 -- the "Shape" type, these "standard" selection
220 -- modes will be automatically activated as a function
221 -- of the modes present in the Local Context.
222 -- The loaded objects will be selectable but
223 -- displayable in highlighting only when detected by the Selector.
224 -- This method is available only when Local Contexts are open.

253 -- Displays current objects if there is no active local context.
254 -- Objects selected when there is no open local context
255 -- are called current objects; those selected in open
256 -- local context, selected objects.

263 KeepTemporary(me : mutable;
264 anIObj : InteractiveObject from AIS;
265 InWhichLocal: Integer from Standard = -1)

267 ---Purpose: Changes the status of a temporary object. It will be
268 -- kept at the neutral point, i.e. put in the list of
269 -- displayed objects along withwith its temporary
270 -- attributes. These include display mode and
271 -- selection mode, for example.
272 -- Returns true if done.
273 -- inWhichLocal gives the local context in which anIObj

366 -- Note that Z layers differ from under-/overlayer in V3d_View:
