You need to have the commandKeyMask bit set in the 3rd parameter to
EvtEnqueuKey, I believe.
To be sure how the keyDownEvent looks like for the VoiceRec button set a
breakpoint in your event loop, press the button and look at the event.

sudden draw window changes - help is needed

[Paul Nevai]

I have a form popping up as an "OS Extension" [OS5 type hack] which is
narrower than the entire screen [I know this is not approved but many other
apps do it too].

Occasionally, on my Tungsten C, the draw window suddenly changes from the form
to the display window.

This happens only on the Tungsten C. My stuff works on all OSs from 3.5 but
the problem appears only on the TC.

Alas, I can't reproduce it, and it happens very rarely. None of my users have
seen it and it takes me some "lucky" taps on the screen to cause the draw
window change.

BTW, I am talking about pToolSet.

Any ideas? Could this be an OS bug? /PaulN

P.S. BTW, pToolSet had some instant reboots on the Tungsten T which I
couldn't trace it either and they have disappeared in the TC so that it was
clearly an OS problem.

There was a bug in one of the dll's. It referenced a file which exists on my
system but doesn't on yours; when the dll tried to open it, it crashed. This
has now been corrected.

I have no idea why it doesn't work on the TT.

there is no native mp3 support - write your own mp3 streaming

to do :), mp3 players do exist on the Tunsten/Zire71 units.

Well, that gets me into the application, but how do I start recording?
Maybe there is a cmd parameter that I can send with the SysAppLaunch that
will cause the recording to begin, but if there is, Sony isn't documenting
that either.

I find the lack of support for 3rd party developers by Sony to be a complete
mystery.  How they think this is smart business, I'll never know.

Yeah, I tried it both ways, but no joy. You're right, I'd normally think it
needs to be set.

Well, once I find a serial cable that will work with the TG50 maybe I'll be
able to actually use a debugger with it.  For now I seem to be stuck with
writing code in the event loop that will draw stuff to the screen.  Unless
someone has a better idea.

If someone knows what the fatal error message means exactly, that might give
me a clue about how to proceed.  Does it mean that PACE won't *let* me queue
an event with eType 0x2F under any circumstance, or that it's not processing
the event because I need to set values for other parameters in the event, or
maybe I'm just making a stupid mistake that I'm not seeing?

Here's how I call EvtAddUniqueEventToQueue:

MemSet(&recEvent, sizeof(EventType), 0);
recEvent.eType = 0x2F;
EvtAddUniqueEventToQueue(&recEvent, 0, true);

I've also tried setting the third parameter to false (just casting about for
other things to try).  The obvious issue is that an event is usually more
than an eType and that's all I'm setting.  I'm willing to try poking around
in the dark for a while, but I thought someone might have a comment about my
general approach--or maybe has actually found a serial cable for debugging a
TG50.  The cables I've seen advertised leave out the TG50 as supported
devices, but I may try one anyway.  If someone has a cable that works (a)
please let me know where they got it, and (b) take a few moments to do as
Jonathan suggested with a breakpoint in the event loop of an app and let me
know what the details are about the event that the Rec button fires.

TIA,
David

Starting up, sorta

[Paul Johnson]

Hi Guys.

I've been asked to do ports of several games and other multimedia apps from
that other PDA to OS5, and have a few basic questions. I'll look into the
how-to's later, but I would appreciate a general feel answer to those below
so I can figure out what's in front of me please.

I dabbled a bit around the time of OS3 so am not a newb, just extremely
rusty and behind the times.

1)Is there still no filing system ?  Is it feasible to simulate a filing
system by using some sort of binary chunk database and a bit of hacking ?
Some of the apps I'm looking at have to generate and receive files (via
hotsync) that will then be sent over the net to a server thats expecting
custom binary files and xml.

2)Are we still doing paletised graphics even on OS5 high-res ?  If so,
can I set all the palette colours to match my app (that won't use the OS
GUI) or are some reserved ?

3)Is there an easy way to load up all my sprites and pictures at run
time rather than spending years putting it all into the resource editor ? If
the format is easy enough, I'm not against compiling my own resource files
from custom data via a homegrown widget program of some sort. Anyone done
this ?

4)I will be using my own blitting routines, so is it safe to assume (or
at least test the validity of) poking an offscreen rectangle with my palette
indexes isn't going to break ?  WinCopyRectangle or whatever it was called
isn't gonna cut it when I need to do alpha-blending effects etc...

5)Is there a better place to ask about games programming than on here ?
Where would that be ?

I know this information is probably all available in the various areas, but
I'm suffering from some serious information overload at the moment and can't
see the wood for the trees. Any help/pointers on the above would be
*extremely* well appreciated.

Many thanks in advance.

Paul Johnson

Multibyte/Unicode Programming

[Victor .]

I know that the current Palm OS doesn't support
Unicode. However, I was wondering if programming using
multibytes is do-able to support application that
display non-roman characters. What i mean is I want my
application to be able to display every single
character in Unicode tables, not only Japanese or
Chinese. Currently, i am trying to start programming
for non-profit inter-cultural language
development/survey to save minor languages which
almost extinct. Another question is whether there are
fonts out there that can print Unicode characters in
Palm OS environment without having to create them one
by one (Unicode has hundreds of thousands of
characters, super tedious to create one by one). I
really appreciate your help. Let's save the world's
languages.

Victor

How do one locate the cause for this Bus error?

[Werner Terreblanche]

My app has suddently started giving "bus error" messages in Pose when I'm
killing a CodeWarrior debug session.   When I run the app (without using the
debug option) then it runs fine and does not give an error.  But as soon as
I try to debug I get this error only at the point where I kill the debug
session.  I can trace the source code right up to the point where the last
instruction in my AppStop() routine have been executed.  So it really looks
like the error occurs when the debugger is busy terminating.

How do one find such an error?  I have spent my entire Sunday afternoon and
can still not figure out what to do.   I do not even know what normally
cause a bus error and why does it only happen at the end of a debug a
session?  Any tips of what to look out for would be greatly appreciated.

Here is an example what the last few lines that I see the log file of POSE:

20.718: --- System Call 0xA39E: |-|-|-|-|-WinRGBToIndex.
20.718: --- System Call 0xA3E0: |-|-|-|-|-|BmpGetColortable.

not in RAM or ROM, nor corresponds to a memory-mapped hardware register.

How to know if the alarm caused power on?

[RaNo]

Hello!

I set alarms for my app with AlmSetAlarm (...), and receive both:
sysAppLaunchCmdAlarmTriggered and sysAppLaunchCmdDisplayAlarm.
None of them, however, can tell me if the alarm caused power on to the
handheld or not. How to distinguish?

(my goal is to sound the alarm and, if handheld was off, turn it off again)

Re: Discovering and using undocumented events on the Clie

Great, that works for the TG50, too!  Thanks, Jonatan (and sorry I spelled
your name wrong earlier)!

It looks like the code I was using to extract the chr code was only giving
me the first byte of the WChar for some reason, which is why I was getting
47 instead of 5901.

Thanks for the tip on Brando.

Re: PenMove in OS5

[Tom Frauenhofer]

I had the same problem on my Tungsten C.  My fix was to write a "tighter" 
event loop on the penDownEvent to go until the penUpEvent was received 
(which you should do for good drawing routines to improve the drawing 
quality).  (Only thing I can think of is that the pen queue is somehow 
getting overrun with penMoveEvents courtesy a faster processor, I'm sure 
there's a better explanation lurking out there...)

Here's an (incomplete) event handler for a form which includes some code 
that should do what you need:

Boolean SomeFormEventHandler(EventType* eventP)
{
EventType evt;
Boolean done = false;
...

case penDownEvent:
// Initialize the drawing using data from the penDown event
while(!done) {
EvtGetEvent(&evt, 1);
switch(evt.eType)
{
case penMoveEvent:
// do some drawing work
break;
case penUpEvent:
done = true;
break;
default:
// Handle other events?
break;
}
}
handled = true;
break;
...

return handled;
}
Remember that you might get other events (such as nilEvents) during the 
processing of this loop, so you have to handle them accordingly.

As far as generating resource files goes, I've successfully used scripts
to create .rcp files that the CodeWarrior pilrc plug-in compiles.  These
worked both from a database and as a script that iterated over a folder
full of Windows bitmaps.  Significantly simplified our resource management.

This gives you standard PalmOS resource files.  I'm not sure if there's
an advantage to getting lower-level than that, except that images packed
together might speed up syncing of the app, but I think that the slow
syncing
of dbs with lot's of small records is much less significant than it used to
be.

on some devices, since os3.5 - you have been capable of doing 16bit 
graphics. nearly all OS5 device are capable of 16bit, but, in worst
case, 8bpp (indexed) maybe required. you can check a feature for the
depth of the display.

yes - done this.

you can use simple .bmp to import as a Tbmp, or, have your own
data format, with your own data-reader to create the sprites you
need. you will just have to keep in mind that 64k is the max size.

you can poke however you want to your offscreen windows. as long
as they are generated with 'genericFormat'. you may not however
poke direct to the screen on OS5 - endian issues etc etc will 
haunt you here (unless you want to support every device seperately).
using the WinCopyRectangle() routine a total of once should be ok.
(ie: copy offscreen -> display)
