I am trying to put a margin attached to the textview in the Visual Studio Editor. I implemented a margin with the given interfaces. I need to put a icon in the margin correspond to each line. I thought I will use the Top property of the TextViewLine to find
the Top co ordinate of each line, But sometime the value return by the Top proper was not something I expect.
In MSDN the definition for Top property given as follows :
Gets the position of the top edge of this line in the text rendering coordinate system.
Some times the return values are -Ve .
How to Interpret the "Top" value? Is there is a reference point from where the "TOP" property value is calculated for each line ?
