Release Candidates :: DSL v4.0rc5

Quote

I haven't looked at your (robert's) code yet, but I plan to make a slight modification to exit.lua. Its current behavior, if you uncheck "backup" and then select "reboot" (or "shutdown" if reboot is already selected), is to automatically re-check "backup". This doesn't seem like a logical behavior, and I assume it will be a minor thing to change.

I did that by design. Intended to be pesky. Don't want no oops; lost data as no backup.

I see.

Well, anyway, I messed with it=o)

Regardless of whether or not you want to encourage the backup, there were two things about the script that I didn't think are necessary. The first (w:callback) I'm not sure about, but the second (backupBtn:callback) I'm pretty sure is a kluge for a bug created by the use of backupBtn:type(). "type" when applied to buttons implies button type, but the type you supplied was a box type. I can't see why this would cause the check button to consistently be "on", but removing the type line stopped it.

Code Sample

[code]w = fltk:Fl_Double_Window(205, 175, "DSL Exit Options")
--[[
-- I don't think this is needed?
w:callback(
function(w)
os.exit(0)
end)
]]

shutdownGroup = fltk:Fl_Group(40, 15, 135, 75)

shutdownBtn = fltk:Fl_Round_Button(55, 15, 95, 25, "Shutdown")
shutdownBtn:type(fltk.FL_RADIO_BUTTON)
shutdownBtn:value(1)
shutdownBtn:callback(
function(shutdownBtn)
-- backupBtn:value(1)
backupBtn:show()
end)

rebootBtn = fltk:Fl_Round_Button(55, 35, 100, 25, "Reboot")
rebootBtn:type(fltk.FL_RADIO_BUTTON)
rebootBtn:value(0)
rebootBtn:callback(
function(rebootBtn)
-- backupBtn:value(1)
backupBtn:show()
end)

promptBtn = fltk:Fl_Round_Button(55, 55, 115, 25, "Exit to Prompt");
promptBtn:type(fltk.FL_RADIO_BUTTON)
promptBtn:value(0)
promptBtn:callback(
function(promptBtn)
-- backupBtn:value(0)
backupBtn:hide()
end)

fltk:Fl_End() -- End of shutdown group

backupBtn = fltk:Fl_Check_Button(70, 85, 80, 30, "Backup")
backupBtn:tooltip("Uncheck to skip backup")
backupBtn:value(1)
--[[
-- I know this isn't needed. The value of backupBtn will normally
-- change itself automatically. Setting the button type to a
-- boxtype causes the problem that this callback fixes.
backupBtn:type(fltk.FL_DOWN_BOX)
backupBtn:callback(
function(backupBtn)
if backupBtn:value() == 0 then
backupBtn:value(1)
else
backupBtn:value(0)
end
end)
]]

--[[ the backup and reboot checks are now nested
inside the prompt check. If the prompt is
true, the others are not checked, and there
is no need to check backup
]]
okBtn = fltk:Fl_Return_Button(25, 130, 60, 25, "OK")
okBtn:callback(
function(okBtn)
if promptBtn:value() == 1 then
os.execute("pidof jwm >/dev/null && pkill jwm")
os.execute("pidof fluxbox && pkill fluxbox")
os.execute("pidof swm && pkill swm")
os.exit(0)
else
if backupBtn:value() == 0 then
os.execute("> /opt/.backup_device")
backupReq = ""
else
backupReq = "yes"
end
if rebootBtn:value() == 1 then
os.execute("/usr/local/bin/exitcheck.sh reboot " .. backupReq)
else
os.execute("/usr/local/bin/exitcheck.sh shutdown " .. backupReq)
end
end
os.exit(0)
end)

cancelBtn = fltk:Fl_Button(115, 130, 60, 25, "Cancel")
cancelBtn:callback(
function(cancelBtn)
os.exit(1)
end)

w:show()
Fl:run()

I agree about the NAG screen to backup, I knew there was a three-finger salute or two to cure that. But I prefer how Puppy gives you three choices instead.

I came across some old laptops so I'm trying DSL 4.5 on them. Tonight it was the WinBook XL2 with a P2 in it and about 200 MB of RAM. It had no problems so far and I first tried my Dlink NIC PC Card, then I tried the Belkin USB to NIC in the 2-port USB PC Card as I'm typing on it.

DSL saw the sound card, but I didn't hear anything. I'm just happy the old ATI video onboard is supported and that it didn't stall out on the PC Card testing.

If I buy one of your fine books will I be entitled to the corrected info for the newer version 4 or 5 of DSL?

Thanks for DSL,
ChiJoan

My ancient Toshiba Tecra is now on-line with DSL 4.0-rc5 but without any sound. It worked in M$ win98...

BIOS settings say 'Soundblaster', 0x220, IRQ5, DMA1 so I tried

Code Sample

modprobe sb io=0x220 irq=5 dma=1

. This looks OK and the mixer starts but as soon as I 'play' anything it locks up!

Is there a lua gui for configuring sound? I can't find anything.

Cheers

Neverless, I have script updated many extensions to add a resized 32x32 .xpm icon. The original 48x48 icon in .xtdesktop remains for continued compatibiliy with DSL 3.x and prior versions.

Now when 4.0 is loading an extension, either at boot up or dynamically a check is made to see if an xpm icon is in /tmp/mydsl.icons and if so the application specific one is used otherwise the fallback generic "open box" icon will be used.

So let me get this straight, future extension makers catering for
both 4.x and pre-4.x will put a 48x48 icon in .xtdesktop as usual, and add a 32x32 icon in /tmp/mydsl.icons/ ?
