AcEdInputPointMonitor::monitorInputPoint final

[Anonymous]

Hi, 

I draw additional info on my custom object when the user selects the object, such as the object's local user axis system as well as its origin point. Previously I did this by over-riding AcEdInputPointMonitor::monitorInputPoint in a special class in the "UI" part of my code (arx part) where I could get a grip on the AcGiViewportDraw* drawContext and so add geometry, such as lines and a circle, to the viewport.

In "acedinpt.h" comments in the new SDK, it notes that this function now is final and states that it will be removed in a future releases. 

Can you please let me know what the new/alternative method would be to accomplish this functionality.

Regards,

JP

You have to use other overloaded method:

virtual Acad::ErrorStatus monitorInputPoint(const AcEdInputPoint& /*input*/,
AcEdInputPointMonitorResult& /*output*/);

Hi Alexander,

Thanks for the reply. I saw this function and tried to implement it. However, I cannot seem to access AcGiViewportDraw* drawContext (which i need to draw in the model space around my custom object). I have seen in the header file that *AcEdInputPointMonitorResult do implement a friend class "friend class AcEdImpInputPointManager" and this pointer do contain "ACAD_PORT AcGiViewportDraw* drawContext() const;". 

Can you please assist in how to return "AcEdInputPointMonitorResult& /*output*/" whilst utilising the drawContext in AcEdImpInputPointManager;

Regards,

JP

Simple sample drawing circle around current point:

//-----------------------------------------------------------------------------
Acad::ErrorStatus PointMonitor::monitorInputPoint(const AcEdInputPoint& inpt /*input*/,
  AcEdInputPointMonitorResult& outpt /*output*/)
{
  if (inpt.pointComputed()) {
     AcGePoint3d pCenter = inpt.computedPoint();
     inpt.drawContext()->geometry().circle(pCenter, 10.0, inpt.drawContext()->viewport().viewDir());
  }

  return Acad::eOk;
}

In the old monitorinputpoint function(before AC2021) the apertureEntities argument exists. But the new function it does not exists in AcEdInputPoint. How to get apertureEntities in monitorinputpoint function.

Try to check pickedEntities() method of AcEdInputPoint class.
