One more thing
As a general rule you never modify a notifier from within one of its reactor functions.
That is why you store the _associatedId within the persistent reactor object.
Which means I need to move the association links from my custom objects to their appropriate prersistent reactor objects which in turn will be stored within the extension dictionary of my custom objects(the notifiers). That way I will be able to update their values (linked objects) form within the reactor modified function.
Is that correct?
Sorry for the delay. I was out-of-office for a few days.
Regarding your query related to spatial index :
I dont see the need to use spatial index with persistent reactors. A change in the object property will automatically ensure that the associated persistent reactors gets a call.
Regarding your other query on using a reactor function to modify a notifier :
You are right, in general reactor callbacks should not be used to modify the database entities, but I havent come across any issues while using persistent reactor callbacks. Please let me know if you have any specific issue while using it.
I wanted to use spatial index so that I will find quickly from the database the objects that are on the same point after a grip edit operation within the GripOpStatFunc when the GripStatus is kGripEnd and then I could update the links between the involved entities. However, I abandoned that approach and I try now again to use setInputPointFunc, but came across the same problem.
When I hover over other entities, pickedEntities parameter will indicate to me whether the type of entity that I am looking for is under the cursor. Then I want to display custom graphics next to the cursor (like Civil3d's Pipe Network, when you grip edit a pipe and you move it over another pipe or structure from the same network then a special glyph is drawn to indicate that the network connections will be updated. This is the process that I would like to mimic).
Now, the question is how do I draw the special graphics from within GripInputPointPtr function. When you use the equivalent AcEdInputPointMonitor::monitorInputPoin
viewContext const AcGiViewport& and viewportID const AcDbObjectId& parameters how these could be used to draw custom glyph graphics while I am dragging the grip?
Maybe, I am wrong with this approach and need to use something else as well.
As far as the GripInputPointPtr question is concerned in my previous post I think I got it I started using setDrawAtDragImageGripPoint to true and modified the worlddraw method for the grip. So I hope I will get the result that I am looking for.
Is there another approach.
What about my comments on spatial index and picked entities on my previous post.
One more thing is there a way to get the environment grip colors that are set at the AutoCAD options dialog from within a grip's worlddraw function.
More specifically if you do not use subEntityTraits().setColor then graphics are drawn with grip colors except GRIPCONTOUR so when you draw a filled square grip then the outline of the square is drawn in the default GRIPCOLOR not GRIPCONTOUR color as in standard AutoCAD grips.
I was busy with other activities.
