Here are some quick sketches of what different parts of the interface
could look like.  None of these is implemented yet, and everything is
open for debate.  Whoever writes the wxwidgets code for any of these
screens gets several thousand votes!



Idea for large configuration dialog, based on Netscape's Edit:Preferences
dialog box.  Here's a sketch of a dialog with all the components that can be
configured in a list on the left, and the details of the selected component
on the right.  This is a pretty familiar structure that's used in a lot of
applications these days.  In the first sketch, "IDE Interface" is selected on
the left, and the details of the IDE devices are shown on the right.

The CD-ROM media can still be configured during the simulation.  In this
context we can just show the Media section.  The same code can be written to
serve both purposes.  This is the dialog that would appear when you click the
CD-ROM button on the toolbar at runtime.

The idea is that you could choose from a set of configurations 
(individual bochsrc files, basically).  When you first install
Bochs, it would just have DLX Linux Demo, and Create New.
As you create new configurations and save them, the list
could grow.

more ambitious: create a button for each key on a standard keyboard, so that
you can view/edit/load/save key mappings, produce any combination of keys 
(esp. ones that your OS or window manager won't allow)

////////////////////////////////////////////////////////////////////////////
// ConfigTimeDialog
////////////////////////////////////////////////////////////////////////////

choose IPS
select starting time for CMOS clock
turn on real time PIT or not (?)
VGA update interval

This dialog can easily allow people to tune the IPS setting, or
various other speed-related values, at runtime.  If you're running
some time-sensitive program you could adjust IPS until it's the right
speed, or if Bochs is wasting all of your CPU's cycles you could turn
a dial to some periodic delays to allow other processes a chance to
complete.

everything in the bochsrc that doesn't fit into some other category,
or that is used so rarely (e.g. floppy command delay) that it's not worth
laying out manually in a dialog box.  This will probably be done in
sort of a grid with parameter name, and value(editable) in different columns

////////////////////////////////////////////////////////////////////////////

lets you choose which events you want to write to the log, which you
want to ignore, etc.  You can do this at a high level, like

This sets up the default actions for all devices.  The advanced
dialog lets you set different actions per device.  I have two
attempts at the advanced dialog.  The first creates a large
grid of wxChoice controls which choose between
ignore/report/ask/die.  There will be enough rows in this
table that a scrolling subwindow will be needed to fit
all the devices.

Try #2 for the advanced event configuration dialog.
It shows the selection of the default actions again
at the top, with some explanation.  Then at bottom, you 
can select a device in the list box and edit the settings 
for that device individually.  It would be possible to 
allow selection of multiple devices and then edit several
devices at once.

| Then, if you want you can edit the actions for          |
