XmWidgetGetBaselines returns an array that contains one or more baseline values associated with the specified widget. The baseline of any given line of text is a vertical offset in pixels from the origin of the widget's bounding box to the given baseline. This routine allocates memory for the returned data. The application must free this memory using XtFree.

| line_count | Returns the number of lines in the widget |
