virtual const char * GetText(
unsigned startIndex
) const =0
Gets the text in an input field.

unsigned startIndex,
unsigned endIndex,
unsigned & lineCount
) =0
Gets the coordinates of the text in the input field.
Parameters:
- startIndex the starting text index
- endIndex the last text position
- lineCount number of text lines in the input field between startIndex and endIndex
Return: a pointer to an array of rectangles, each representing the area covered by text in the corresponding text line
Note: the pointer will be valid until the next call of GetTextPositions
function SetText
