The dlineinfo method returns a list of five items. These items describe the area of the line that contains index:
X coordinate of the upper-left corner
Y coordinate of the upper-left corner
Width of the area
Height of the area
Baseline position of the line, measured from x
Here is an example call:
($x, $y, $w, $h, $base) = $text->lineinfo("index");
Unlike the bboxmethod, even areas not shown (due to nonwrapped characters) are used in the calculations as long as some of the line is showing. However, if the line is not visible at all on the screen, the list will be empty. If the line happens to wrap to multiple lines, the entire area is used.
