For the tiling to work correctly, the children of an +Fl_Tile must cover the entire area of the widget, but not +overlap. This means that all children must touch each +other at their edges, and no gaps can't be left inside the +Fl_Tile. + +
Fl_Tile does not normailly draw any graphics of its own. +The "borders" which can be seen in the snapshot above +are actually part of the children. Their boxtypes have been set +to FL_DOWN_BOX creating the impression of +"ridges" where the boxes touch. What you see are +actually two adjacent FL_DOWN_BOX's drawn next to each +other. All neighboring widgets share the same edge - the widget's +thick borders make it appear as though the widgets aren't actually +touching, but they are. If the edges of adjacent widgets do not +touch, then it will be impossible to drag the corresponding +edges.
+Fl_Tile allows objects to be resized to zero dimensions. To prevent this you can use the resizable() to limit where corners can be dragged to.
