control panel are all implemented as bx_list_c, and look much like
they did before.
- removed many hardcoded UI functions from control.cc, since the
much more general "text_ask" methods have replaced them.
- add range checking on integer parameter values. This exposed several
cases where my initial value for an integer parameter was not in range.
- cleaned up behavior of get/set methods. The get/set methods allow the
handler to override the value that is returned/set, or perform side
effects.
- the title parameter of a bx_list_c now defaults to the name.
- now bx_param_c fields that used to be private are protected instead
- removed references to bx_any
- moved definition of set_handler from siminterface.h to siminterface.cc.
I was considering with doing a "set" of the old value when the
handler is first installed, but that remains commented out.
- BX_BOOT_DISKA and BX_BOOT_DISKC are now 0,1 so that they can correspond
with the values of a bx_param_enum_c. For a while they were 0x00 and 0x80
corresponding to the numbering convention of the bios, but it didn't
really matter.
been converted into parameters temporarily have the letter "O" appended
to their name. I don't want to keep it this way, but it has helped
in the conversion process because the compiler refuses to compile the
old uses of the name. Before I started using the "O" trick, there were
many bugs like this: if (bx_options.diskc.present) {...}
This was legal with the new parameters, but it was testing whether the
parameter structure had been created, instead of testing the value of
the present parameter. Renaming present to Opresent turns this into
a compile error, which points out the incorrect use of the param.
- the "--disable-control-panel" no longer works, I'm afraid. I can no
longer support this and continue progress.
crash in the mouse code. The particular problem was that init_done
was never initialized to zero, but it always turned out to be zero
on my system. This may explain why it worked for me but crashed
for him.
bochs debugger needed to be updated in the same way. Instead of
using "bx_options.rom.path" as a string, it's now
bx_options.rom.path->getptr () to get the value of the parameter.
data structures, see bx_init_options in main.cc. The implementation
of this menu and all its choices is 17 lines long, see do_mem_options_menu
in gui/control.cc.
now the whole "Bochs Memory Options" menu uses new style parameters.
The next step is to remove the hardcoded stuff that generates and runs
this menu, and replace it with general menu building code. All you should
need to create this menu is the string "Bochs Memory Options", and the
IDs of the bx_param_c options that should appear on the menu. The
bx_param_c structure for each parameter tell what type it is, how to
display it, constraints on the value, what to do when the parameter
changes.
declared as bx_param_c * types in the bx_options structure. They are
initialized in main.cc (bx_init_options) with default values.
Access to parameters of this type should always be like this:
bx_options.mouse_enabled->get ();
bx_options.mouse_enabled->set (newval);
Eventually I will be transferring all options to this format.
