In Fl_Tree, why do space and left click behave differently? Looking in the source, I just noticed, for instance, how in the FL_TREE_SELECT_SINGLE case, ctrl-space deselects all, but left click always does select_only for an item. I see that clicking _not_ on an item deselects all, but I have tree->showroot(0); tree->connectorstyle(FL_TREE_CONNECTOR_NONE); tree->marginleft(-14); because I don't want that showing on the widget for a select element.
