35class InteractiveContext from AIS inherits TShared from MMgt
36
37 ---Purpose: The Interactive Context allows you to manage
38 -- graphic behavior and selection of Interactive Objects
39 -- in one or more viewers. Class methods make this
40 -- highly transparent.
41 -- It is essential to remember that an Interactive Object
42 -- which is already known by the Interactive Context
43 -- must be modified using Context methods. You can
44 -- only directly call the methods available for an
45 -- Interactive Object if it has not been loaded into an
46 -- Interactive Context.
47 -- You must distinguish two states in the Interactive Context:
48 -- - No Open Local Context, also known as the Neutral Point.
49 -- - One or several open local contexts, each
50 -- representing a temporary state of selection and presentation.
51 -- Some methods can only be used in open Local
52 -- Context; others in closed Local Context; others do
53 -- not have the same behavior in one state as in the other.
54 -- The possiblities of use for local contexts are
55 -- numerous depending on the type of operation that
56 -- you want to perform, for example:
57 -- - working on all visualized interactive objects,
58 -- - working on only a few objects,
59 -- - working on a single object.
60 -- 1. When you want ot work on one type of entity, you
61 -- should open a local context with the option
62 -- UseDisplayedObjects set to false. DisplayedObjects
63 -- allows you to recover the visualized Interactive
64 -- Objects which have a given Type and
65 -- Signature from Neutral Point.
66 -- 2. You must keep in mind the fact that when you open
67 -- a Local Context with default options:
68 -- - The Interactive Objects visualized at Neutral Point
69 -- are activated with their default selection mode. You
70 -- must deactivate those which you do not want ot use.
71 -- - The Shape type Interactive Objects are
72 -- automatically decomposed into sub-shapes when
73 -- standard activation modes are launched.
74 -- - The "temporary" Interactive Objects present in the
75 -- Local Contexts are not automatically taken into
76 -- account. You have to load them manually if you
77 -- want to use them.
78 -- - The stages could be the following:
79 -- - Open a Local Context with the right options;
80 -- - Load/Visualize the required complementary
81 -- objects with the desired activation modes.
82 -- - Activate Standard modes if necessary
83 -- - Create its filters and add them to the Local Context
84 -- - Detect/Select/recover the desired entities
85 -- - Close the Local Context with the adequate index.
86 -- - It is useful to create an interactive editor, to which
87 -- you pass the Interactive Context. This will take care
88 -- of setting up the different contexts of
89 -- selection/presentation according to the operation
90 -- which you want to perform.

140 Create(MainViewer:Viewer from V3d)
141 returns mutable InteractiveContext from AIS;
142 ---Purpose:
143 -- Constructs the interactive context object defined by
144 -- the principal viewer MainViewer.
145
146 Create(MainViewer,Collector: Viewer from V3d)
147 returns mutable InteractiveContext from AIS;
148 ---Purpose:
149 -- Constructs the interactive context object defined by
150 -- the principal viewer MainViewer and the collector
151 -- (or trash) viewer.
152
153
154 Delete(me) is redefined;

164 ---Category: General DISPLAY SERVICES
165 SetAutoActivateSelection( me: mutable; Auto : Boolean from Standard );
166 GetAutoActivateSelection( me ) returns Boolean from Standard;
167
168
169 Display(me : mutable;
170 anIobj : InteractiveObject from AIS;
171 updateviewer : Boolean from Standard = Standard_True);
172 ---Purpose: Controls the choice between the using the display
173 -- and selection modes of open local context which you
174 -- have defined and activating those available by default.
175 -- If a local context is open and if updateviewer equals
176 -- Standard_False, the Interactive Object anIobj is
177 -- displayed in the default active mode. This will be the
178 -- object's default display mode, if there is one.
179 -- Otherwise, it will be the context mode. The Interactive
180 -- Object's default selection mode is activated. In
181 -- general, this is 0.
182 -- This syntax has the same behavior as local context,
183 -- open or closed. If you want to view the object in open
184 -- local context without selection, use the syntax below,
185 -- setting aSelectionMode to -1.
186
187 Display(me : mutable;
188 anIobj : InteractiveObject from AIS;
189 amode : Integer from Standard ;
190 aSelectionMode : Integer from Standard ;
191 updateviewer : Boolean from Standard = Standard_True;
192 allowdecomposition : Boolean from Standard = Standard_True);
193 ---Purpose: Controls the choice between the using the display
194 -- and selection modes of open local context which you
195 -- have defined and activating those available by default.
196 -- If no Local Context is opened. and the Interactive
197 -- Object aniobj has no display mode of its own, the
198 -- default display mode, 0, is used. Likewise, if aniobj
199 -- has no selection mode of its own, the default one, 0, is used.
200 -- If a local context is open and if updateviewer equals
201 -- Standard_False, the presentation of the Interactive
202 -- Object activates the selection mode; the object is
203 -- displayed but no viewer will be updated.
204 -- If aSelectionMode equals -1, anIobj will not be
205 -- activated: it will be displayed but will not be selectable.
206 -- Use this if you want to view the object in open local
207 -- context without selection. Note: This option is only
208 -- available in Local Context.
209 -- If allowDecomposition equals true, anIObj can have
210 -- subshapes detected by selection mechanisms. anIObj
211 -- must be able to give a shape selection modes which
212 -- fit the AIS_Shape selection modes:
213 -- - vertices: 1
214 -- - edges: 2
215 -- - wires: 3.
216
217 Load(me:mutable;
218 aniobj : InteractiveObject from AIS;
219 SelectionMode : Integer from Standard = -1;
220 AllowDecomp : Boolean from Standard = Standard_False);
221 ---Purpose: Allows you to load the Interactive Object aniobj
222 -- with a given selection mode SelectionMode, and/or
223-- with the desired decomposition option, whether the
224-- object is visualized or not. If AllowDecomp =
225-- Standard_True and, if the interactive object is of
226-- the "Shape" type, these "standard" selection
227-- modes will be automatically activated as a function
228-- of the modes present in the Local Context.
229-- The loaded objects will be selectable but
230-- displayable in highlighting only when detected by the Selector.
231-- This method is available only when Local Contexts are open.
232
233
234 Erase(me : mutable;
235 aniobj : InteractiveObject from AIS;
236 updateviewer : Boolean from Standard = Standard_True;
237 PutInCollector : Boolean from Standard = Standard_False);
238---Purpose: To erase presentations in current local context, or
239-- failing that, in other local contexts which allow erasing.
240--
241-- If putinCollector is True, the object is erased with graphical status Erased,
242-- and put into the Collector. These objects can be retrieved
243-- from Interactive Context by ObjectsInCollector method.
244-- If putinCollector is False, the objects erased with graphical status FullErased,
245-- and not put into the Collector. These objects can be retrieved
246-- from Interactive Context by ErasedObjects method.
247--
248-- Note: objects that are put into the Collector recomute their presentation
249-- for Collector Presentation Manager.
250--
251-- If a local context is open and if updateviewer is
252-- False, the presentation of the Interactive
253-- Object activates the selection mode; the object is
254-- displayed but no viewer will be updated.
255
256 EraseMode(me : mutable;
257 aniobj : InteractiveObject from AIS;
258 aMode : Integer from Standard;
259 updateviewer : Boolean from Standard = Standard_True);
260 ---Purpose: Updates viewer contents and returns the display
261-- mode of each aniobj object. Use only if more than
262-- one display mode is active in the main viewer.
263-- This method works only on presentation modes other
264-- than the default mode. Nothing is done if aMode is
265-- the default presentation mode.
266-- If a local context is open and if updateviewer equals
267-- Standard_False, the presentation of the Interactive
268-- Object activates the selection mode; the object is
269-- displayed but no viewer will be updated.
270
271
272
273 EraseAll(me:mutable;
274 PutInCollector : Boolean from Standard = Standard_False;
275 updateviewer : Boolean from Standard = Standard_True);
276 ---Purpose: Every erased object goes into the Collector viewer,
277 -- depending on PutInCollector value.
278
279 DisplayAll(me : mutable;
280 OnlyFromCollector : Boolean from Standard = Standard_False;
281 updateviewer : Boolean from Standard = Standard_True);
282 ---Purpose: Displays all erased objects or display all objects from collector
283
284 DisplayFromCollector(me : mutable;
285 anIObj : InteractiveObject from AIS;
286 updateviewer : Boolean from Standard = Standard_True);
287 ---Purpose: display anIObj from the collector.
288
289 EraseSelected(me:mutable;
290 PutInCollector:Boolean from Standard=Standard_False;
291 updateviewer:Boolean from Standard = Standard_True);
292 ---Purpose:
293-- Erases selected objects if there is no open active local context.
294-- If there is no local context activated and if
295-- updateviewer equals Standard_False, the
296-- presentation of the Interactive Object activates the
297-- selection mode; the object is displayed but no viewer
298-- will be updated.
299-- If a local context is open, this method is neutral.
300
301 DisplaySelected(me:mutable;updateviewer:Boolean from Standard = Standard_True);
302 ---Purpose: Displays selected objects if a local context is open.
303-- Displays current objects if there is no active local context.
304-- Objects selected when there is no open local context
305-- are called current objects; those selected in open
306-- local context, selected objects.
307-- If a local context is open and if updateviewer equals
308-- Standard_False, the presentation of the Interactive
309-- Object activates the selection mode; the object is
310-- displayed but no viewer will be updated.
311
312
313 KeepTemporary(me : mutable;
314 anIObj : InteractiveObject from AIS;
315 InWhichLocal: Integer from Standard = -1)
316 returns Boolean from Standard;
317---Purpose: Changes the status of a temporary object. It will be
318-- kept at the neutral point, i.e. put in the list of
319-- displayed objects along withwith its temporary
320-- attributes. These include display mode and
321-- selection mode, for example.
322-- Returns true if done.
323-- inWhichLocal gives the local context in which anIObj
324-- is displayed. By default, the index -1 refers to the last
325-- Local Context opened.
326
327 Clear(me : mutable;
328 aniobj : InteractiveObject from AIS;
329 updateviewer : Boolean from Standard = Standard_True);
330---Purpose: Removes the interactive object aniobj from all viewers.
331-- If a local context is open and if updateviewer equals
332-- Standard_False, the presentation of the Interactive
333-- Object activates the selection mode; the object is
334-- displayed but no viewer will be updated.
335
336 ClearPrs( me :mutable;
337 aniobj : InteractiveObject from AIS;
338 aMode : Integer from Standard = 0;
339 updateviewer : Boolean from Standard = Standard_True);
340 ---Purpose: Empties the graphic presentation of the mode
341-- indexed by aMode.
342-- If a local context is open and if updateviewer equals
343-- Standard_False, the presentation of the Interactive
344-- Object activates the selection mode; the object is
345-- displayed but no viewer will be updated.
346-- Warning
347-- Removes anIobj. anIobj is still active if it was
348-- previously activated.
349
350 Remove(me:mutable;
351 aniobj : InteractiveObject from AIS;
352 updateviewer : Boolean from Standard = Standard_True);
353 ---Purpose: Removes aniobj from every viewer. aniobj is no
354-- longer referenced in the Context.
355-- If a local context is open and if updateviewer equals
356-- Standard_False, the presentation of the Interactive
357-- Object activates the selection mode; the object is
358-- displayed but no viewer will be updated.
359
360 RemoveAll(me:mutable;
361 updateviewer : Boolean from Standard = Standard_True);
362 ---Purpose: Removes all the objects from all opened Local Contexts
363 -- and from the Neutral Point
364
365
366 Hilight(me:mutable;
367 aniobj : InteractiveObject from AIS;
368 updateviewer: Boolean from Standard = Standard_True);
369 ---Purpose:
370-- Updates the display in the viewer to take dynamic
371-- detection into account. On dynamic detection by the
372-- mouse cursor, sensitive primitives are highlighted.
373-- The highlight color of entities detected by mouse
374-- movement is white by default.
375-- If a local context is open and if updateviewer equals
376-- Standard_False, the presentation of the Interactive
377-- Object activates the selection mode; the object is
378-- displayed but no viewer will be updated.
379
380 HilightWithColor(me:mutable;
381 aniobj :InteractiveObject from AIS;
382 aCol : NameOfColor from Quantity;
383 updateviewer: Boolean from Standard = Standard_True);
384---Purpose:
385-- Changes the color of all the lines of the object in view,
386-- aniobj. It paints these lines the color passed as the
387-- argument, aCol.
388-- If a local context is open and if updateviewer equals
389-- Standard_False, the presentation of the Interactive
390-- Object activates the selection mode; the object is
391-- displayed but no viewer will be updated.
392
393 Unhilight(me:mutable;
394 aniobj : InteractiveObject from AIS;
395 updateviewer: Boolean from Standard = Standard_True);
396---Purpose:
397-- Removes hilighting from the entity aniobj. Updates the viewer.
398-- If a local context is open and if updateviewer equals
399-- Standard_False, the presentation of the Interactive
400-- Object activates the selection mode; the object is
401-- displayed but no viewer will be updated.
402
403 SetDisplayPriority(me:mutable;
404 anIobj: InteractiveObject from AIS;
405 aPriority : Integer from Standard);
406 ---Purpose: Sets the display priority aPriority of the seen parts
407-- presentation of the entity anIobj.
408
409 SetZLayer( me : mutable;
410 theIObj : InteractiveObject from AIS;
411 theLayerId : Integer from Standard );
412 ---Purpose: Set Z layer id for interactive object. The layer can be
413 -- specified for displayed object only. The Z layers can be used to display
414 -- temporarily presentations of some object in front of the other objects
415 -- in the scene. The ids for Z layers are generated by V3d_Viewer.
416 -- Note that Z layers differ from under-/overlayer in V3d_View:
417 -- under-/overlayer are intended for specific 2D drawings that appear
418 -- behind/in front of all 3D presentations, while SetZLayer() method
419 -- applies to regular 3D presentations and does not imply any specific
420 -- drawing methods.
421
422 GetZLayer( me;
423 theIObj : InteractiveObject from AIS )
424 returns Integer from Standard;
425 ---Purpose: Get Z layer id set for displayed interactive object.
426 -- If the object doesn't exists in context or has no computed presentations,
427 -- the method returns -1.
428
429 Redisplay(me : mutable;
430 aniobj : InteractiveObject from AIS;
431 updateviewer : Boolean from Standard = Standard_True;
432 allmodes : Boolean from Standard = Standard_False);
433 ---Purpose: Recomputes the seen parts presentation of the entity
434-- aniobj. If allmodes equals true, all presentations are
435-- present in the object even if unseen.
436-- If a local context is open and if updateviewer equals
437-- Standard_False, the presentation of the Interactive
438-- Object activates the selection mode; the object is
439-- displayed but no viewer will be updated.
440
441 Redisplay(me : mutable;
442 aTypeOfObject: KindOfInteractive from AIS;
443 Signature : Integer from Standard =-1;
444 updateviewer : Boolean from Standard = Standard_True);
445 ---Purpose: Recomputes the Prs/Selection of displayed objects of
446 -- a given type and a given signature.
447 -- if signature = -1 doesnt take signature criterion.
448
449
450 RecomputePrsOnly(me:mutable;
451 anIobj : InteractiveObject from AIS;
452 updateviewer : Boolean from Standard = Standard_True;
453 allmodes : Boolean from Standard = Standard_False);
454 ---Purpose: Recomputes the displayed presentations, flags the others
455 -- Doesn't update presentations
456
457
458
459 RecomputeSelectionOnly(me:mutable;
460 anIObj : InteractiveObject from AIS);
461 ---Purpose: Recomputes the active selections, flags the others
462 -- Doesn't update presentations
463
464 Update(me : mutable;
465 anIobj : InteractiveObject from AIS;
466 updateviewer : Boolean from Standard = Standard_True);
467 ---Purpose: Checks which presentations are flagged "to be recomputed"
468 -- and recomputes them if they are displayed.
469 -- This method doesn't force any Computation.
470 -- Recomputes Flagged selections if they are activated.
471

474
475 SetDisplayMode(me : mutable;
476 aniobj : InteractiveObject from AIS;
477 aMode : Integer from Standard;
478 updateviewer: Boolean from Standard = Standard_True);
479
480---Purpose:
481-- Sets the display mode of seen Interactive Objects.
482-- aMode provides the display mode index of the entity aniobj.
483-- If updateviewer equals Standard_True, the
484-- predominant mode aMode will overule the context mode.
485-- If a local context is open and if updateviewer equals
486-- Standard_False, the presentation of the Interactive
487-- Object returns to the default selection mode; the
488-- object is displayed but no viewer will be updated.
489-- Note that display mode 3 is only used if you have an
490-- AIS_Textured Shape.
491
492
493 UnsetDisplayMode(me : mutable;
494 aniobj : InteractiveObject from AIS;
495 updateviewer: Boolean from Standard = Standard_True);
496---Purpose:
497-- Unsets the display mode of seen Interactive Objects.
498-- aMode provides the display mode index of the entity aniobj.
499-- If updateviewer equals Standard_True, the
500-- predominant mode aMode will overule the context mode.
501-- If a local context is open and if updateviewer equals
502-- Standard_False, the presentation of the Interactive
503-- Object returns to the default selection mode; the
504-- object is displayed but no viewer will be updated.
505 SetSelectionMode(me:mutable;
506 aniobj:InteractiveObject from AIS;
507 aMode :Integer from Standard);
508---Purpose:
509-- Sets the selection mode of Interactive Objects.
510-- aMode provides the selection mode index of the entity aniobj.
511 UnsetSelectionMode(me : mutable;
512 aniobj : InteractiveObject from AIS);
513---Purpose:
514-- Removes selection mode from Interactive Objects.
515-- aMode provides the selection mode index of the entity aniobj.
516
517 SetSensitivity(me:mutable;
518 aPrecision: Real from Standard);
519 ---Level: Public
520 ---Purpose: Sets the sensitivity aPrecision
521-- according to the view size for the current context or local
522-- context if any is activated.
523-- Sets the sensitivity aPrecision in pixels for the current context
524-- or local context if any is activated. By default, this
525-- sensitivity is equal to 4 pixels.
526-- When a local context is open, the defined sensitivity applies to
527-- this local context instead of the main context.
528
529 SetSensitivity(me:mutable;
530 aPrecision: Integer from Standard = 4);
531 ---Level: Public
532 ---Purpose: Define the current selection pixel sensitivity
533 -- for this context or local context if any one is activated.
534 -- Warning: When a local context is open the sensitivity is apply on it
535 -- instead on the main context.

541 aniobj : InteractiveObject from AIS;
542 aLocation : Location from TopLoc);
543---Purpose: Puts the location aLocation on the initial graphic
544-- representation and the selection for the entity aniobj.
545-- In other words, aniobj is visible and selectable at a
546-- position other than initial position.
547-- Graphic and selection primitives are not recomputed.
548-- To clean the view correctly, you must reset the previous location.
549
550 ResetLocation(me : mutable;
551 aniobj : InteractiveObject from AIS);
552 ---Purpose: Puts the entity aniobj back into its initial position.
553
