function help_spacing(self) % Small buttons called "spacers" along the edge of the SeaGrid % boundary allow the grid-lines to be rearranged smoothly. To see % the spacers, use the "View/Spacers" menu item. By dragging the % spacers closer together, using mouse Button #1, the intervening % grid lines themselves can be brought closer together. To drag % a spacer without forcing a full update of the window, use Button % #2. (Note: when lines are very closely spaced, they may disappear % from the drawing, because of the "xor" drawing mode. They do not, % however, disappear from the computed grid.) % The number of spacers is controlled by the "View/Spacer Count" % dialog. Initially, there are five spacers along the two principal % edges of the grid. % To restore the default spacing, use the "View/Default Spacing..." % menu item to display the corresponding dialog. The spacings % along the two principal edges are entered as functions of "s", % which uniformly spans the range of [0:1]. The dialog also permits % the spacers to be moved to the opposite side of the grid. % Copyright (C) 1999 Dr. Charles R.
