How to add tooltip for selected point / entity for AcEdInputPointMonitor

[majklha]

I use my own class AcEdInputPointMonitor for selecting point from preslect group of points.

I am not able to add tooltips during slection. 

class CMajPointMonitor : public AcEdInputPointMonitor
{
protected:
	const vector<AcGePoint2d>* m_pVecOfBody;
....
}
Acad::ErrorStatus CMajPointMonitor::monitorInputPoint(const AcEdInputPoint &input /*input*/,
													  AcEdInputPointMonitorResult &output /*output*/)
{
	if (input.pointComputed())
	{

		AcGePoint2d ptCurr = asPnt2d(input.computedPoint());
		AcGePoint2d ptNear = getNearestPoint(asPnt2d(input.computedPoint()));

		AcCmEntityColor cm(255, 255, 0);
		input.drawContext()->subEntityTraits().setTrueColor(cm);
		input.drawContext()->geometry().circle(asPnt3d(ptNear), MajDraw::GetRozmerZnacky() / 2, input.drawContext()->viewport().viewDir());
		if (m_pptStartBod) 
		{
			AcGePoint3d pnts[2] = { asPnt3d(ptNear), asPnt3d(*m_pptStartBod) };
			input.drawContext()->geometry().worldLine(pnts);
			output.setAdditionalTooltipString(L"Tool");
			output.appendToTooltipStr();
		}
	}
	return Acad::eOk;
}
