HELP: gadget
{ $class-description "An object which displays itself on the screen and acts on user input gestures. Gadgets have the following slots:"
{ $list
{ { $link "pref-dim" } " - a cached value for " { $link pref-dim } "; do not read or write this slot directly." }
{ { $link "parent" } " - the gadget containing this one, or " { $link f } " if this gadget is not part of the visible gadget hierarchy." }
{ { $link "children" } " - a vector of child gadgets. Do not modify this vector directly, instead use " { $link add-gadget } ", " { $link add-gadgets } ", " { $link unparent } " or " { $link clear-gadget } "." }
{ { $link "orientation" } " - an orientation specifier. This slot is used by layout gadgets." }
{ { $link "layout-state" } " - stores the layout state of the gadget. Do not read or write this slot directly, instead call " { $link relayout } " and " { $link relayout-1 } " if the gadget needs to be re-laid out." }
{ { $link "visible?" } " - a boolean indicating if the gadget should display and receive user input." }
{ { $link "root?" } " - if set to " { $link t } ", layout changes in this gadget will not propagate to the gadget's parent." }
{ { $link "clipped?" } " - a boolean indicating if clipping will be enabled when drawing this gadget's children." }
{ { $link "interior" } " - an object whose class implements the " { $link draw-interior } " generic word." }
{ { $link "boundary" } " - an object whose class implements the " { $link draw-boundary } " generic word." }
{ { $link "model" } " - a " { $link model } " or " { $link f } "; see " { $link "ui-control-impl" } }
{ { $snippet "pref-dim" } " - a cached value for " { $link pref-dim } "; do not read or write this slot directly." }
