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

145 Create(MainViewer:Viewer from V3d)
146 returns mutable InteractiveContext from AIS;
147 ---Purpose:
148 -- Constructs the interactive context object defined by
149 -- the principal viewer MainViewer.
150
151 Delete(me) is redefined;
152
153 ---Category: General DISPLAY SERVICES
154 SetAutoActivateSelection( me: mutable; Auto : Boolean from Standard );
155 GetAutoActivateSelection( me ) returns Boolean from Standard;
156
157
158 Display(me : mutable;
159 anIobj : InteractiveObject from AIS;
160 updateviewer : Boolean from Standard = Standard_True);
161 ---Purpose: Controls the choice between the using the display
162 -- and selection modes of open local context which you
163 -- have defined and activating those available by default.
164 -- If a local context is open and if updateviewer equals
165 -- Standard_False, the Interactive Object anIobj is
166 -- displayed in the default active mode. This will be the
167 -- object's default display mode, if there is one.
168 -- Otherwise, it will be the context mode. The Interactive
169 -- Object's default selection mode is activated. In
170 -- general, this is 0.
171 -- This syntax has the same behavior as local context,
172 -- open or closed. If you want to view the object in open
173 -- local context without selection, use the syntax below,
174 -- setting aSelectionMode to -1.
175
176 Display(me : mutable;
177 anIobj : InteractiveObject from AIS;
178 amode : Integer from Standard ;
179 aSelectionMode : Integer from Standard ;
180 updateviewer : Boolean from Standard = Standard_True;
181 allowdecomposition : Boolean from Standard = Standard_True);
182 ---Purpose: Controls the choice between the using the display
183 -- and selection modes of open local context which you
184 -- have defined and activating those available by default.
185 -- If no Local Context is opened. and the Interactive
186 -- Object aniobj has no display mode of its own, the
187 -- default display mode, 0, is used. Likewise, if aniobj
188 -- has no selection mode of its own, the default one, 0, is used.
189 -- If a local context is open and if updateviewer equals
190 -- Standard_False, the presentation of the Interactive
191 -- Object activates the selection mode; the object is
192 -- displayed but no viewer will be updated.
193 -- If aSelectionMode equals -1, anIobj will not be
194 -- activated: it will be displayed but will not be selectable.
195 -- Use this if you want to view the object in open local
196 -- context without selection. Note: This option is only
197 -- available in Local Context.
198 -- If allowDecomposition equals true, anIObj can have
199 -- subshapes detected by selection mechanisms. anIObj
200 -- must be able to give a shape selection modes which
201 -- fit the AIS_Shape selection modes:
202 -- - vertices: 1
203 -- - edges: 2
204 -- - wires: 3.
205
206 Load(me:mutable;
207 aniobj : InteractiveObject from AIS;
208 SelectionMode : Integer from Standard = -1;
209 AllowDecomp : Boolean from Standard = Standard_False);
210 ---Purpose: Allows you to load the Interactive Object aniobj
211 -- with a given selection mode SelectionMode, and/or
212-- with the desired decomposition option, whether the
213-- object is visualized or not. If AllowDecomp =
214-- Standard_True and, if the interactive object is of
215-- the "Shape" type, these "standard" selection
216-- modes will be automatically activated as a function
217-- of the modes present in the Local Context.
218-- The loaded objects will be selectable but
219-- displayable in highlighting only when detected by the Selector.
220-- This method is available only when Local Contexts are open.
221
222
223 Erase(me : mutable;
224 aniobj : InteractiveObject from AIS;
225 updateviewer : Boolean from Standard = Standard_True);
226---Purpose: Hides the object. The object's presentations are simply
227-- flagged as invisible and therefore excluded from redrawing.
228-- To show hidden objects, use Display().
229
230 EraseAll (me : mutable;
231 updateviewer: Boolean from Standard = Standard_True);
232 ---Purpose: Hides all objects. The object's presentations are simply
233-- flagged as invisible and therefore excluded from redrawing.
234-- To show all hidden objects, use DisplayAll().
235
236 DisplayAll(me : mutable;
237 updateviewer: Boolean from Standard = Standard_True);
238 ---Purpose: Displays all hidden objects.
239
240 EraseSelected(me: mutable;
241 updateviewer: Boolean from Standard = Standard_True);
242 ---Purpose:
243-- Hides selected objects. The object's presentations are simply
244-- flagged as invisible and therefore excluded from redrawing.
245-- To show hidden objects, use Display().
246
247 DisplaySelected(me:mutable;updateviewer:Boolean from Standard = Standard_True);
248 ---Purpose: Displays selected objects if a local context is open.
249-- Displays current objects if there is no active local context.
250-- Objects selected when there is no open local context
251-- are called current objects; those selected in open
252-- local context, selected objects.
253-- If a local context is open and if updateviewer equals
254-- Standard_False, the presentation of the Interactive
255-- Object activates the selection mode; the object is
256-- displayed but no viewer will be updated.
257
258
259 KeepTemporary(me : mutable;
260 anIObj : InteractiveObject from AIS;
261 InWhichLocal: Integer from Standard = -1)
262 returns Boolean from Standard;
263---Purpose: Changes the status of a temporary object. It will be
264-- kept at the neutral point, i.e. put in the list of
265-- displayed objects along withwith its temporary
266-- attributes. These include display mode and
267-- selection mode, for example.
268-- Returns true if done.
269-- inWhichLocal gives the local context in which anIObj
270-- is displayed. By default, the index -1 refers to the last
271-- Local Context opened.
272
273 Clear(me : mutable;
274 aniobj : InteractiveObject from AIS;
275 updateviewer : Boolean from Standard = Standard_True);
276---Purpose: Removes the interactive object aniobj from all viewers.
277-- If a local context is open and if updateviewer equals
278-- Standard_False, the presentation of the Interactive
279-- Object activates the selection mode; the object is
280-- displayed but no viewer will be updated.
281
282 ClearPrs( me :mutable;
283 aniobj : InteractiveObject from AIS;
284 aMode : Integer from Standard = 0;
285 updateviewer : Boolean from Standard = Standard_True);
286 ---Purpose: Empties the graphic presentation of the mode
287-- indexed by aMode.
288-- If a local context is open and if updateviewer equals
289-- Standard_False, the presentation of the Interactive
290-- Object activates the selection mode; the object is
291-- displayed but no viewer will be updated.
292-- Warning
293-- Removes anIobj. anIobj is still active if it was
294-- previously activated.
295
296 Remove(me:mutable;
297 aniobj : InteractiveObject from AIS;
298 updateviewer : Boolean from Standard = Standard_True);
299 ---Purpose: Removes aniobj from every viewer. aniobj is no
300-- longer referenced in the Context.
301-- If a local context is open and if updateviewer equals
302-- Standard_False, the presentation of the Interactive
303-- Object activates the selection mode; the object is
304-- displayed but no viewer will be updated.
305
306 RemoveAll(me:mutable;
307 updateviewer : Boolean from Standard = Standard_True);
308 ---Purpose: Removes all the objects from all opened Local Contexts
309 -- and from the Neutral Point
310
311
312 Hilight(me:mutable;
313 aniobj : InteractiveObject from AIS;
314 updateviewer: Boolean from Standard = Standard_True);
315 ---Purpose:
316-- Updates the display in the viewer to take dynamic
317-- detection into account. On dynamic detection by the
318-- mouse cursor, sensitive primitives are highlighted.
319-- The highlight color of entities detected by mouse
320-- movement is white by default.
321-- If a local context is open and if updateviewer equals
322-- Standard_False, the presentation of the Interactive
323-- Object activates the selection mode; the object is
324-- displayed but no viewer will be updated.
325
326 HilightWithColor(me:mutable;
327 aniobj :InteractiveObject from AIS;
328 aCol : NameOfColor from Quantity;
329 updateviewer: Boolean from Standard = Standard_True);
330---Purpose:
331-- Changes the color of all the lines of the object in view,
332-- aniobj. It paints these lines the color passed as the
333-- argument, aCol.
334-- If a local context is open and if updateviewer equals
335-- Standard_False, the presentation of the Interactive
336-- Object activates the selection mode; the object is
337-- displayed but no viewer will be updated.
338
339 Unhilight(me:mutable;
340 aniobj : InteractiveObject from AIS;
341 updateviewer: Boolean from Standard = Standard_True);
342---Purpose:
343-- Removes hilighting from the entity aniobj. Updates the viewer.
344-- If a local context is open and if updateviewer equals
345-- Standard_False, the presentation of the Interactive
346-- Object activates the selection mode; the object is
347-- displayed but no viewer will be updated.
348
349 SetDisplayPriority(me:mutable;
350 anIobj: InteractiveObject from AIS;
351 aPriority : Integer from Standard);
352 ---Purpose: Sets the display priority aPriority of the seen parts
353-- presentation of the entity anIobj.
354
355 SetZLayer( me : mutable;
356 theIObj : InteractiveObject from AIS;
357 theLayerId : Integer from Standard );
358 ---Purpose: Set Z layer id for interactive object. The layer can be
359 -- specified for displayed object only. The Z layers can be used to display
360 -- temporarily presentations of some object in front of the other objects
361 -- in the scene. The ids for Z layers are generated by V3d_Viewer.
362 -- Note that Z layers differ from under-/overlayer in V3d_View:
363 -- under-/overlayer are intended for specific 2D drawings that appear
364 -- behind/in front of all 3D presentations, while SetZLayer() method
365 -- applies to regular 3D presentations and does not imply any specific
366 -- drawing methods.
367
368 GetZLayer( me;
369 theIObj : InteractiveObject from AIS )
370 returns Integer from Standard;
371 ---Purpose: Get Z layer id set for displayed interactive object.
372 -- If the object doesn't exists in context or has no computed presentations,
373 -- the method returns -1.
374
375 Redisplay(me : mutable;
376 aniobj : InteractiveObject from AIS;
377 updateviewer : Boolean from Standard = Standard_True;
378 allmodes : Boolean from Standard = Standard_False);
379 ---Purpose: Recomputes the seen parts presentation of the entity
380-- aniobj. If allmodes equals true, all presentations are
381-- present in the object even if unseen.
382-- If a local context is open and if updateviewer equals
383-- Standard_False, the presentation of the Interactive
384-- Object activates the selection mode; the object is
385-- displayed but no viewer will be updated.
386
387 Redisplay(me : mutable;
388 aTypeOfObject: KindOfInteractive from AIS;
389 Signature : Integer from Standard =-1;
390 updateviewer : Boolean from Standard = Standard_True);
391 ---Purpose: Recomputes the Prs/Selection of displayed objects of
392 -- a given type and a given signature.
393 -- if signature = -1 doesnt take signature criterion.
394
395
396 RecomputePrsOnly(me:mutable;

401 -- Doesn't update presentations
402
403
404
405 RecomputeSelectionOnly(me:mutable;
406 anIObj : InteractiveObject from AIS);
407 ---Purpose: Recomputes the active selections, flags the others
408 -- Doesn't update presentations
409
410 Update (me : mutable;
411 theIObj : InteractiveObject from AIS;
412 theUpdateViewer : Boolean from Standard = Standard_True);
413 ---Purpose: Updates displayed interactive object by checking and
414 -- recomputing its flagged as "to be recomputed" presentation
415 -- and selection structures. This method does not force any
416 -- recomputation on its own. The method recomputes selections
417 -- even if they are loaded without activation in particular selector.
418
419 SetDisplayMode(me : mutable;
420 aniobj : InteractiveObject from AIS;
421 aMode : Integer from Standard;
422 updateviewer: Boolean from Standard = Standard_True);
423
424---Purpose:
425-- Sets the display mode of seen Interactive Objects.
426-- aMode provides the display mode index of the entity aniobj.
427-- If updateviewer equals Standard_True, the
428-- predominant mode aMode will overule the context mode.
429-- If a local context is open and if updateviewer equals
430-- Standard_False, the presentation of the Interactive
431-- Object returns to the default selection mode; the
432-- object is displayed but no viewer will be updated.
433-- Note that display mode 3 is only used if you have an
434-- AIS_Textured Shape.
435

438 aniobj : InteractiveObject from AIS;
439 updateviewer: Boolean from Standard = Standard_True);
440---Purpose:
441-- Unsets the display mode of seen Interactive Objects.
442-- aMode provides the display mode index of the entity aniobj.
443-- If updateviewer equals Standard_True, the
444-- predominant mode aMode will overule the context mode.
445-- If a local context is open and if updateviewer equals
446-- Standard_False, the presentation of the Interactive
447-- Object returns to the default selection mode; the
448-- object is displayed but no viewer will be updated.
449 SetSelectionMode(me:mutable;
450 aniobj:InteractiveObject from AIS;
451 aMode :Integer from Standard);
452---Purpose:
453-- Sets the selection mode of Interactive Objects.
454-- aMode provides the selection mode index of the entity aniobj.

459-- aMode provides the selection mode index of the entity aniobj.
460
461 SetSensitivityMode(me : mutable;
462 aMode : SensitivityMode from StdSelect) is static;
463 ---Level: Public
464 ---Purpose: Sets the selection sensitivity mode. SM_WINDOW mode
465 -- uses the specified pixel tolerance to compute the sensitivity
466 -- value, SM_VIEW mode allows to define the sensitivity manually.
467
468 SensitivityMode(me) returns SensitivityMode from StdSelect;
469 ---Level: Public
470 ---Purpose: Returns the selection sensitivity mode.

476-- according to the view size for the current context or local
477-- context if any is activated.
478-- Sets the sensitivity aPrecision in pixels for the current context
479-- or local context if any is activated. By default, this
480-- sensitivity is equal to 4 pixels.
481-- When a local context is open, the defined sensitivity applies to
482-- this local context instead of the main context.
483
484 Sensitivity (me) returns Real from Standard;
485 ---Level: Public
486 ---Purpose: Returns the selection sensitivity value.

1544-- - UseDisplayedObjects -allows you to load or not
1545-- load the interactive objects visualized at Neutral
1546-- Point in the local context which you open. If false,
1547-- the local context is empty after being opened. If
1548-- true, the objects at Neutral Point are loaded by their

1552-- mode of objects at Neutral Point which are
1553-- type-"privileged". This Flag is only taken into
1554-- account when UseDisplayedObjects is true.
