This method is not named getInputMap() because there is
a package-private method in BasicTextAreaUI with that name.
Thus, creating a new method with that name causes certain compilers to
issue warnings that you are not actually overriding the original method
(since it is package-private).

RSyntaxTextArea changes its syntax editing style.public int yForLine(int line)
throws javax.swing.text.BadLocationException
This method is quicker than using traditional
modelToView(int) calls, as the entire bounding box isn't
computed.
yForLine in class RTextAreaUIline - The line number.-1 if
this text area doesn't yet have a positive size or the line is
hidden (i.e. from folding).javax.swing.text.BadLocationException - If line isn't a valid line
number for this document.public int yForLineContaining(int offs)
throws javax.swing.text.BadLocationException
This is faster than calling modelToView(offs).y, so it is
preferred if you do not need the actual bounding box.
yForLineContaining in class RTextAreaUIoffs - The offset info the document.-1 if
this text area doesn't yet have a positive size or the line is
hidden (i.e. from folding).javax.swing.text.BadLocationException - If offs isn't a valid offset
into the document.
