TikTok is designed to be a simple, no nonsense, timer utility for a Palm OS device. Using it is dead simple. Tick on a checkbox to start a timer, edit it's description to tell you what it is you are timing. Simple!

Special Notes

The application ID 'DAP2' is registered with Palm Computing. If you intend to make changes and release your own free version based on this code please make sure you change the application ID.

Please note that TikTok is free software, licensed under the GPL. Be sure to read the section on Copying for full details.

If you have any feedback or comments (or bugs) please feel free to mail them to TikTok@MikeMcCollister.com. Before you do mail me with any questions and/or bugs, please read the FAQ section first, your question may already have been answered.

The latest version of TikTok will always be available from MikeMcCollister.com/palm/.

If you are upgrading from an earlier version of TikTok you can find out what has changed by reading the Version History section.

I. Installation

Installation of TikTok is just like any other Palm program.

IMPORTANT: If upgrading from version 1.0x, 2.01 or 2.02 of TikTok, your preferences and current timers will be lost due to a new preferences format.

II. System Requirements

Requires Palm OS 2.0 or greater. 29 Kbytes of free memory on the Palm is required.

III. ZIP File Contents

TikTok.prc		The TikTok application that you install on your Palm OS device.
README.htm		This file
Note: If the files and directories below are not available, then download the source code at MikeMcCollister.com/palm/TikTokSource.zip.
Makefile		Makefile for building TikTok.
obj/		Obj directory where object files are stored during a make. See directory for contents.
src/		Source directory where source files are stored. See directory for contents.

IV. Usage

To start a timer check its start/stop checkbox. To stop a timer un-check its start/stop checkbox.

A timer can be made to be "persistent" by checking its "persistent" checkbox. In this case, "persistent" means that when you stop it, and then re-start it, instead of starting from 0.00:00:00 it will carry on counting in the place you left off.

You can edit the time field of a non-running timer and set the time value to anything you like. If you set the time to a negative value the time will count down to 0.00:00:00 and an alarm will sound when 0 is reached.

The TikTok timers will carry on working when other applications are running and when your Palm is turned off.

Be sure to check out the Options->Preferences menu item for configuration.

  - Use new types (i.e. UInt8 instead of Byte) when applicable.
  - New header file format.
  - The pragma pack(2) is no longer needed
  - Modified the Makefile so that it will work with PRC-Tools 2.0.

- Better aligned the preferences dialog.
- Added Graffiti Help menu item.
- Moved the graffiti indicator so that it looks OK on Palm OS 1.0.
- Changed the large icon to make it look a little better.
- Created a small icon.
- Display updates tweaked to make stuff appear faster.
- "Clear" menu renamed to "Tools".
- Zero all function no longer displays all zero and then clears the empty alarms.
- Compiled with PilRC 2.4 so that menu shortcuts are spaced properly.
- Cleaned up the Makefile
- Icon is now BMP format.
- Removed all warnings from source code.
- Removed the FrmInitForm line before FrmPopupForm so that it will not cause a memory leak on the emulator.
- There is now always an alarm with focus, even when the preferences have been cleared.
- Changed the timeout from 1 to 50 to reduce the power consumption.
- Added FldSetTextHandle to StuffTikTok to avoid warning/error on the Palm OS Debugger.
- Added MenuEraseStatus(MenuGetActiveMenu()) to the menu portion of the case statement so that menu shortcut messages at the bottom of the screen don't get clobbered.
- Time time is now displayed using WinDrawChars instead of using fields. This ensures that focus will always be placed on a valid field.
- Removed all references to TxtFieldHasFocus function because a text field will now always have focus.
- Source code now looks good in 80 columns.
- The main form now responds to frmCloseEvent to prevent any possible memory leaks that were showing up in the emulator.
- The alarm is now sounded when the sysAppLaunchCmdAlarmTriggered event is received. This allows for the alarm to beep when other alarm dialogs are currently up.
- Array sizes are now sized using defines.
- Added DEFAULTBUTTON to dialogs that have multiple buttons. This defines what button is "pressed" when the the program is exited when a dialog is up. The dialogs effected now default to a "no".
- Function prototypes now contain variable names.
1.07
- Fixed a bug in RaiseAlarm() that caused a FE if the timer that was kicking in had an empty description.
- You can now tell TikTok that you want timers to stop counting when they are acting as an alarm and they go off. See the options dialog for the setting (thanks to Kadar Tanuwidjaja <ktan8@dgs.monash.edu.au> for the patch that this change is based on).
- You can now tell TikTok to use a timers last starting time when you tick it on a second time. See the options dialog for the setting (thanks to Kadar Tanuwidjaja <ktan8@dgs.monash.edu.au> for the patch that this change is based on).
1.06
- Minor tweaks to the prefs structures to reduce the memory needed to hold the timer details.
- Improved the look of the interface (thanks to J. Y. Mantinband <yosh@mantinband.com> for the suggestions).
- Added "zero timer" options to the Clear menu.
- Added a "quick alarms" menu.
- Added an extra config option that lets you tell TikTok that you don't want to be asked silly questions when you say you want to clear/zero all timers.
- Added an optional clock display (thanks to Holger Klawitter <holger@math.uni-muenster.de> for the suggestion).
1.05
- PilotMain() now returns sysErrParamErr if the cmd is not known or used by TikTok (source: <syK3zYbo8GA.74@darrin2.massena.com> in pilot.programmer.gcc on news.massena.com).
- Many tweaks to the code to try and kill the menu-death-bug.
- Moved to GCC 0.5.0. It appears that 0.4.0 was the cause of the menu-death-bug.
1.04
- Removed the input filter on the time fields. Next time I'll think things thru a lot better before I add something like this. :-)
1.03
- Corrected a couple of minor bugs which shouldn't have been user visible but were bad coding.
- When writing in the "time" field, all characters that are not "0-9:." are ignored.
1.02
- Corrected a couple of spelling mistakes.
- All time fields are now editable.
- If a user enters a negative value in a time field it is considered to be a countdown timer and will trip an alarm when it hits 0.
- Added options form that allows you to specify if alarms should just be audible or visible as well.
- You can now use the Palm's up/down keys to start and stop a timer (both keys work the same, they toggle the currently focused timer).

VI. FAQ

Is there any chance of adding feature X?
Possibly. Mail me with your suggestion and I'll consider it. I can't guarantee that I'll add it, but, if I like it, if it can be done and if I can do it and it makes sense for TikTok I'll probably add it. Failing that, you have the source code.... :-)
Can I register TikTok?
No, TikTok is free software, read the Copying section for full details. However, if you do feel the need to send someone some money why not consider making a donation to the Free Software Foundation? Pop over to www.fsf.org to find out about them.
Can I modify and distribute my own version of TikTok?
Read the Copying section for a full answer to this question.
Alarms appear to kick in up to 60 seconds late!
This is a known "problem" with the Palm. If your Palm is turned on an alarm should fire right on time. However, if your Palm is turned off an alarm can kick in up to 60 seconds late. From what I've seen most software that uses alarms suffers from this. I'm afraid there is nothing I can do about this, it appears to be the way the Palm works.
Why can't I time things down to 100th of a second?
Because TikTok is not designed to do that. It's designed to be a simple, pretty accurate, stopwatch utility. I'd not advise that you time any critical event. I wrote TikTok to time things where a couple of seconds here and there don't matter (that's not to say that TikTok is that sloppy).

If you want a stopwatch that can go down to 100th of a second I'd suggest you take a look at Chronos (check your local Palm software library for full details).

VII. Bugs

No bugs known at this time.

VIII. To Do

Here are some of the things, in no special order, that I intend to get round to doing at some time in the near future.

Flexible configuration per timer.
Make the quick alarms menu configurable.

IX. Credits

Thanks go to the following people who have mailed bug reports and suggestions or have submitted code during the development of TikTok:

Robert Noe
Found the bug in that if there were two (or more) count down timers that the alarm display would come up for both (all) of them at the same time.
Douglas Turner <dturner@mercuryadvisors.com>
Suggestion for the ability to start/stop all (or selected) timers simultaneously with a single stroke or key press.
Andrew Robertson <Andrew_Robertson@compuserve.com>
Alerted me to my terrible abuse of my native language in the tips screen.
Jim Aspnes <aspnes@cs.yale.edu>
Submitted a patch to allow countdown timers with alarms. This patch formed the basis of the countdown ability of v1.02. Also gave lots of support and ideas when I was getting stuck with bits and bobs.
Iain Barclay <isb@pobox.com>
Help and ideas and was good enough to read and reply to my mail while I was attempting to get my head around various bits of Palm coding. He also runs the excellent RoadCoders web site (check it out at www.roadcoders.com) and is the author of the (IMHO) #1 timer application, BugMe!
J. Y. Mantinband <yosh@mantinband.com>
Thanks for sticking with 1.05 and testing each release above and beyond the call of duty.
Andrew Ball <aball@icis.on.ca>
For helping me work out if the menu-death-bug was a problem with the compiler and for patching TikTok to work with 0.5.0. Andy is also the author of the excellent Chronos, if you want a serious stopwatch, clock and countdown timer you should check out Chronos.
Holger Klawitter <holger@math.uni-muenster.de>
For the clock display suggestion.
Kadar Tanuwidjaja <ktan8@dgs.monash.edu.au>
For a patch that added the "timer memory" and "halting alarms" features.

GNU GENERAL PUBLIC LICENSE <www.gnu.org/copyleft/gpl.html>

Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place - Suite 330, Boston, MA 02111-1307, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too.

When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.

Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and modification follow.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:

a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.

In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.

If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.

4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.

6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.

7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.

9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.

10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.
