RE: Checkboxes won't uncheck
From: Grosch, Scott [mailto:[EMAIL PROTECTED]] That's somewhat confusing that they should all be 0. Group zero is a special value meaning no group and is used for all standalone check boxes. Any nonzero group number turns checkboxes into (functionally) radio buttons, as you have seen. The OS won't complain if such a group happens to contain only one button, as your example did. -slj- -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
Re: faster drawing in 4bit mode?
Le dimanche, 29 sep 2002, à 06:37 Europe/Paris, Palm Guy a écrit : Hi All I have a Palm m125 and an m130. I have written a game that runs in both color (8 bit mode) and gray (4 bit mode). I am using WinDrawBitmap to draw bitmaps onto the screen at 10 frames/sec. What surprises me is that the graphics/drawing run very fast on the m130 in color mode but much more slowly on the m125 in 4 bit grayscale mode. This surprises me because the m125 and the m130 have the same processor speed. Is there any reason why the graphics should be so much slower in 4 bit mode than in 8 bit mode? The m130 use a graphics accelerator, from MediaQ. -- Daniel Morais http://www.kickoo.com -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Hi! Is there any way to draw faster in 4 bit mode? Anyone out there have any super fast low level drawing methods that I can use to augment or replace WinDrawBitmap?

MediaQ (was: faster drawing in 4bit mode?)
Hi! The m130 use a graphics accelerator, from MediaQ. Is there some way to detect the presence of such an accelerator? How does its speed compare to handcrafted assembly routines? In my game framework I have some very fast assembly routines, but can alternatively use a pure version that only uses officially sanctioned PalmOS calls. So my question is: Does it make sense to recognize the presence of an accelerator and then switch to using Palm OS, because it will be faster than the handcrafted assembly routines?

Re: creating unique ID with FldNewField etc.
Let's say your the last UID of a control in your form is (unlikely). Even now you could use UIDs up to 32768 (or something like that). For each new dynamicaly created control increase the number, e.g.: first control: 1 second control: 10001 third control: 10002 AFAIK you can have the same ID in two (or more) different forms, but not in the same. Hans-Christoph Wirth [EMAIL PROTECTED] schrieb im Newsbeitrag news:93696@palm-dev-forum... I am using PalmOS 3.5. There's a bunch of routines to create UI objects at runtime, e.g. FldNewField() and CtlNewControl(). All routines require to specify the ID of the new object. As I understand, this ID should be unique throughout the application (at least throughout the current form). How do I create an ID which is unique? Of course I can use #define and manually select IDs. I would consider this as hardcoded as it might interfere with any automatic creation of IDs, e.g. when using PilRC to create static UI objects. Is there a safer way? hcw -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Re: Procedure Alarms
The SDK 5.0 Ref manual says about procedure alarms: Procedure alarms also differ from regular system alarms in that if they trigger when the device is in sleep mode, the LCD does not light up. Thus, you can use procedure alarms to perform a scheduled task in a manner that is entirely hidden from the user. I've got a simple procedure alarm that sets a feature and calls AlmSetProcAlarm. Whenever it's called, the LCD on all the devices I've tested it on comes on, even if they're asleep. Anyone have any experience with this? Are the docs wrong or am I missing the secret incantation?

CategoryInitilaize() - Item 0
I've been trying to initialize the Categories for my application using CategoryInitialize() and an AppInfoString.

A Palm OS system shared library is a chunk of code that can be used by multiple applications on the device. It exports functions through a dispatch table, and has a single global pointer allocated to it by the system that it can use to store data between calls. For starters, I'd look at the SampleLib project that's part of the Palm OS SDK examples. It has a lot of comments. If you're using CodeWarrior for Palm OS V8, we have a wizard to help you create a new shared library. This project only support C source files -- you can use C++, but you won't be able to expose class methods as library functions, and you won't be able to use virtual functions or exceptions, because shared libraries don't have their own global variables. A shared library can have its own resources, but it will need to explicitly open its program database using DmOpenDatabase to have access to them, or DmGetResource will fail, or worse, find another resource with the same ID. -- Ben Combee [EMAIL PROTECTED] CodeWarrior for Palm OS technical lead Palm OS programming help @ www.palmoswerks.com -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
Re: faster drawing in 4bit mode?
Thanks for the tip. I looked at the source code and it looks like you are using C functions for particular situations such as X coordinate a multiple of 2, etc. But for the arbitrary case where these specific conditions are not satisfied, you resort to using the PalmOS functions. Is this the case or am I missing something? Is it true that in the arbitrary case (no special conditions satisfied by the sprite bitmaps) there is no faster way to draw than the PalmOS methods? Another approach might be for me to only redraw a portion of the screen. Suppose I have an image in my offscreen drawing window, where this image is just a frame of may game that I want to blast to the screen say 10 times a second. Suppose that I can identify say 6 non-overlapping rectangles within that image that need to be redrawn. The sprite and background bitmaps needed to redraw the screen are available in global memory (or in my class members, whatever). My question is: if I were to just set 6 clipping rectangles within the my image and rebuild the portions of the image within those 6 clipping rectangles, would that be faster than redrawing? I know that in J2ME, the drawing is not faster because the entire image is still handled even though it is actually drawn only inside the clipping rectangle. But, on PalmOS if it is possible to set a clipping region and rebuild the image within the clipping regiond and do this much faster than redrawing the entire image, then that is an approach I would like to use.

The current state of Razor is only an intermediate step towards the final goal, with 4bpp being slightly behind 8bpp. Right now I am using an optimized copying loop for the ideal case, in which entire bytes can be copied, and let the OS handle the arbitrary case. I am absolutely convinced that it won't be hard to be a lot faster than the OS for the arbitrary case. I just haven't gotten around to doing this yet.

My question is: if I were to just set 6 clipping rectangles within the my image and rebuild the portions of the image within those 6 clipping rectangles, would that be faster than redrawing? I know that in I know of a game named Rogue Bomber at SourceForge. They switched from such a dirty rectangle list to a version that redraws larger regions than are neccessary, and copies the entire doublebuffer. They report a big increase in speed. The setup and execution costs for clipped copying and clipped drawing are rather high. See their discussion article at http://sourceforge.net/forum/forum.php?thread_id=687137forum_id=61067 In Razor! I also do not determine the dirty rectangles precisely. I only do vertical calculations and always affect the entire width of the screen. I also merge all dirty rectangles into a single one, which is then processed. The only case where this is noticeable less efficient than a less crude method is when you have few sprites, some at the very top of the screen, some at the very bottom. This is merged into one dirty rectangle that covers the entire screen, instead of two small ones.
