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.
- Specifies the Text widget ID
- 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 forward; a negative value causes the lines to scroll backward.
