| JGraphpadMarqueeHandler | | public class JGraphpadMarqueeHandler extends BasicMarqueeHandler (Code) | | Marquee handler that implements popup menus and folding (by icon). This
implements the event processing order for all graphs in the following way:
- If a folding icon is under the mouse pointer all processing is blocked
until the mouse is released. On release, the group's collapsed state is
toggled and the group is selected.
- If the right mouse button is used without holding down the shift key
then a popup menu is displayed. If there is a cell under the mouse pointer
which is not selected, then the cell is selected on mouse down. If the mouse
is right-clicked on the background then the selection is cleared before the
popup is displayed.
