Hints can take arguments in a number of formats, which are described in full in the LispWorks CAPI Reference Manual . When given a number, the layout is constrained to that number of pixels. A number of characters can also be specified, as shown in the next example.
In the last section, you created a window with five panes, by combining row and column layouts. Now consider changing the definition of the editor pane so that it required to have a minimum size. This would be a sensible change to make, because editor panes need to be large enough to work with comfortably.
(setq editor2 (make-instance 'editor-pane
:visible-min-width '(:character 30)
:visible-min-height '(:character 10)))
You will now have to place this new editor into the layouts that contained the old one. Only one layout is affected: the overall column layout which brings all the panes together.
Before typing the following into the listener, you should close down all the windows created in this chapter in order to free up the instances of button1 , button2 and so forth.
(contain (make-instance 'column-layout
:description
(list row1 row2 editor2)))
