[sldev] LLViewerObject and hover text

[Kent Quirk (Q Linden)]

Well, I haven't worked with this area specifically, but from a quick  
look through the code, I think what you want is an instance of the  
LLHudText class (which is the type of the mText object).

In llviewerobject.cpp, there's this code:

					// Setup object text
					if (!mText)
					{
						mText = (LLHUDText  
*)LLHUDObject::addHUDObject(LLHUDObject::LL_HUD_TEXT);
						mText->setFont(LLFontGL::sSansSerif);
						mText->setVertAlignment(LLHUDText::ALIGN_VERT_TOP);
						mText->setMaxLines(-1);
						mText->setSourceObject(this);
						mText->setOnHUDAttachment(isHUDAttachment());
					}

and then:
					mText->setColor(LLColor4(coloru));
					mText->setStringUTF8(temp_string);

Is that the hint you're looking for? See llhudtext.h/cpp for more.
