+For wxGTK using GTK+ 1.2.x and earlier, the number of lines in a multi-line
+text control is calculated by actually counting newline characters in the
+buffer, i.e. this function returns the number of logical lines and doesn't
+depend on whether any of them are wrapped. For all the other platforms, the
+number of physical lines in the control is returned.
+
+Also note that you may wish to avoid using functions that work with line
+numbers if you are working with controls that contain large amounts of text as
+this function has $O(N)$ complexity for $N$ being the number of lines.
