Here are some CLIM2.0 questions:
1. In CLIM1.1 the generic function window-set-viewport-position*
was called each time when clicking on the scrollbars.
In CLIM2.0 the generic function window-set-viewport-position (without asterix)
is not called when clicking on the scrollbars as described in the manual on page 304.
Is this a bug or am I doing something wrong?
WINDOW-SET-VIEWPORT-POSITION* was at the wrong level of modularity for
this in CLIM 2.0. The generic function you need to specialize to
observe when a window is scrolled is NOTE-VIEWPORT-POSITION-CHANGED. It
gets called on the frame, the pane, and (soon) the new X and Y
positions. The default method for this does nothing.
2. How can we change the text-style, size and color of the standard command menu?
Under Allegro, I don't know how to do this.
3. Why does the :command option also display a menu when clicking on it, and
is there a way to avoid that?
(clim::define-application-frame proroad ()
delete edit move depict toggle
load save infrastructure
:menu (("Exit" :command (com-quit-proroad))
("Refresh Map" :command (com-refresh-map))
("Refresh Mapper" :command (com-refresh-mapper))
("Traffic Generation" :command (com-start-traffic))
("Infrastructure >" :menu infrastructure)
("Simulation Commands >" :menu simulation)
In Genera CLIM, this does not display a menu. There may be a UI
consistency issue that CER decided to address for Allegro CLIM.
