Draws the children of a pinboard-layout, by default.
Positive real numbers.
The generic function
pinboard-layout-display is the default
of pinboard-layout (see output-pane for documentation of
). It is responsible for the drawing of all the children of the pinboard layout.
If you want to have drawing on a pinboard-layout which is not done via the children, you can either supply your own
to do the other drawing and call
pinboard-layout-display (or draw-pinboard-layout-objects) to draw the children, or subclass pinboard-layout and add methods to
pinboard-layout-display specialized on your class.
In either case, if any of your drawing is "behind" the children, that is children may overlap it and need to obscure it, you need to do your drawing first and then tell the pane about it by calling redraw-pinboard-layout with the region that was redrawn and the optional argument
In LispWorks 6.1 and earlier versions the default
pinboard-pane-display and was not exported, but apparently some programmers defined methods on it anyway. If you did this, you must change your method to
pinboard-layout-display for LispWorks 7.0 and later versions.
