XmTextScroll scrolls text by a given number of lines in a Text widget. The sign of the
number is interpreted according to the value of the XmNlayoutDirection resource.
widget Specifies the Text widget ID
lines Specifies the number of lines of text to scroll. A positive value causes text to
scroll upward; a negative value causes text to scroll downward. Note that the
text will scroll only as long as one line of text remains visible in the window.
If a navigator exists, this function uses the XmQTnavigator trait to update the
vertical navigator's value.
In the case of vertical writing, a positive value causes the text to scroll for-
ward; a negative value causes the lines to scroll backward.
