Re: Runtime package
by Peter William Lount 07 May '99

07 May '99

Hi, The problem with the approach described below is that it's just for the Mac. A more general solution would be in keeping with Squeaks cross platform portability. I wonder if it's possible for a general solution or if each platform needs it's own specific solution (much like the FileDirectory class hierarchy) wrapped in an abstract class. The other issue is creating a "script" that removes all unwanted components (like the development environment) from Squeak and then setting up your "application object" to launch once Squeak has loaded.

Re: [fix] Lost of menubar in 'full screen on' mode
by Javier Diaz 06 May '99

06 May '99

This fix is for Mac Squeak source 'sqMacWindow.c', when in 'full screen on' mode if you switch to other application with Command-Tab you lost the menubar, this is because the VM is not processing the suspend/resume event. Add this lines in function HandleEvents(void): case osEvt: /* this restore menubar in suspendMessage. JDR. */ switch ((theEvent.message >> 24) & 0x0FF) { /* high byte of message */ Boolean gInBackground; case suspendResumeMessage: /* suspend/resume is also an activate/deactivate */ gInBackground = (theEvent.message & resumeFlag) == 0; if (fullScreenFlag) { if (gInBackground) { MenuBarRestore(); } else { MenuBarHide(); } } break; } break; Also the function MenuBarRestore is incomplete, needs to be: void MenuBarRestore(void) { /* Restore the menu bar from its saved state. Do nothing if it isn''t hidden. */ /* Many thanks to John McIntosh for this code!! */ WindowPtr win; if (menuBarRegion == nil) return; /* no saved state, so menu bar is not hidden */ DiffRgn(LMGetGrayRgn(), menuBarRegion, LMGetGrayRgn()); LMSetMBarHeight(menuBarHeight); win = FrontWindow(); /* to restore menubar in suspendMessage. JDR. */ if (win) { CalcVis(win); CalcVisBehind(win, menuBarRegion); } HiliteMenu(0); DisposeRgn(menuBarRegion); menuBarRegion = nil; DrawMenuBar(); } Finally the SIZE flag 'acceptSuspendResumeEvents' needs to be activated in the CW proyect.

Thanks Mark and Bruce. When I meant the runtime package, I wanted only the application window to show up. In the development environment, applications show up in the Squeak window. Thanks Shiro Ogawa

The Unix VMs ioSeconds() primitive is not correct. I once tried to find a solution - but I did not succeed. I'll attach the mail I sent to Ian one month ago. Maybe you guys have more patience than me getting this right ... ------------------------------------------- Hi Ian, my Squeak still doesn't do "Time now" right. It's off by one hour. I haven't really tracked it down, but I guess it has to do with daylight saving. I wrote a little C program: #include <stdio.h> #include <sys/time.h> #include <unistd.h> int main() { struct timeval tv; gettimeofday(&tv, 0); printf("timezone: %i\n", timezone); printf("daylight: %i\n", daylight); printf("localtime(): %s", asctime(localtime(&tv.tv_sec))); printf("gmtime(): %s", asctime(gmtime(&tv.tv_sec))); printf("timezone: %i\n", timezone); printf("daylight: %i\n", daylight); } This produces timezone: 0 daylight: 0 localtime(): Wed Apr 7 15:17:57 1999 gmtime(): Wed Apr 7 13:17:57 1999 timezone: -3600 daylight: 1 but Time now gives 2:18:19 pm ... First observation: timezone is not set before localtime() is called. Second: It does not reflect daylight saving. Any idea? ------------------------------------------- /bert -- Bert Freudenberg Department of Simulation and mailto:bert@isg.cs.uni-magdeburg.de Computer Graphics http://isgwww.cs.uni-magdeburg.de/isg/bert.html Univ. of Magdeburg

Error using #bitEdit [BUG]

Something simple like (Form extent: 10@10 depth: 8) bitEdit now fails with 'Message not understood: asParagraph' in PluggableButtonView>>label:. This works in 2.4 beta at change set 787 (old style) and fails in 2.4b at change set 1192 (new style). Cheers, Bob

RE: Squeak 2.4b keeps Crashing
by Raab, Andreas 06 May '99

06 May '99

Folks, I want to ask a favor of those of you guys who had the crashes when running Squeak on Windows Laptops - could you please download an updated VM version from http://isgwww.cs.uni-magdeburg.de/~raab/squeak/bin/Squeak24bEXP.exe This VM has a couple of extra checks in the virtual memory support code (which seems to be the problem on those laptops) and should be capable of reporting what the actual problem with those machines is. If you're getting any message boxes talking about virtual memory problems, please write down the messages exactly (including any hex numbers!) and send me a message so that I know what to fix. Thanks a lot, Andreas PS. If the VM crashes and you get none of the error messages let me know this, too. It means that my guess about the source of the problem is wrong. -- +===== Andreas Raab ========= (andreasr(a)wdi.disney.com) ==+ | Walt Disney Imagineering Phone: +1 818 544 5016 I I Glendale, CA Fax: +1 818 544 4544 I +======< http://isgwww.cs.uni-magdeburg.de/~raab >========+

The following line is commented out because otherwise it simply overwrites what was in cmdMap (e.g. home, end ). " cmdMap at: ((cmds at: i) asciiValue - 96 + 1) put: (cmds at: i + 1). " "ctrl keys" Reinier.

[BUG/FIX] Socket class new
by mdr＠scn.org 05 May '99

05 May '99

"Socket new" used to automatically send the message "initialize" to the newly created socket. With recent socket updates that stopped happening and so old-style clients (e.g. Celeste) fail to initialize the socket. Attached is the changed method. It just adds initialize after the newTCP. Mike mdr(a)scn.org /////// (Socket class) new "Return a new, unconnected Socket. Note that since socket creation may fail, it is safer to use the method createIfFail: to handle such failures gracefully; this method is primarily for backward compatibility and may be disallowed in a future release." "Note: The default creates a TCP socket - this is also backward compatibility." ^self newTCP initialize

time one hour early?

I notice my squeak time is an hour early. (Intel x86). Any suggestions? Just for grins, I tried recompiling with "undef HAS_TIMEZONE", which did not change the results. linux: Wed May 5 20:20:42 UTC 1999 linux: Wed May 5 15:20:42 CDT 1999 squeak: Time now (printIt) 2:20:42 pm -- Stan
