How much work should be done to port QTE to palm devices? Is there a lot of hardware-specific code? Palm handhels have 480x320 or 320x320 framebuffer, hardware buttons are passed as F9-F12 (or any other) keys, touchscreen works for X11.

I am not an expert on this, but I would imagine it would depend on the palm device. The new palms seem to use Intel XScale processors, so they would probably be pretty easy. The older ones use...eh....other processors lol. I would imagine that the lack of multitasking in the Palm OS is due to processor limitations on the earlier Palm devices. (not to mention severe memory limitations)

This may not be too far away anyway, since PalmOS is done with now; Palm is going to Linux.
http://www.palmsource.com/press/2004/120804_cms.html - You'll find in this article how Palm's system will be built on top of Linux.
There are also some projects like the Palm Linux Environment.

2katrina: I'm interested in Palm devices based on arm cpus (Intel PXA and TI OMAP, both ARMv5TE).
2CuCullin: I'm a developer of linux version for Palm Tungsten T3, also interested in QTE on LifeDrive, T|T5, T|X, Zire72
Well when a linux distribution ( kernel + basic apps ) will run on Palm devices,
I think compilling QTEmbedded will not be very difficult.
Usually, core libs like QTEmbedded use the kernel and other libs to comunicate with the hardware. This helps to make the software easy to compile for any platform/machines ( maybe we could also build it for toasters or microwaves if we manage to run aLinux kernel on these )
As for the screen difference between devices, QT/E use the kernel's framebuffer to draw on the screen. If the framebuffer driver is working, the hardware difference should not have any impacts on QT. Only the top layers of softwares ( like QTopia/Opie ) may have to be adjusted to the resolutions
Good luck in your project!
Oh, I thought something like that. Basic linux applications are running, so I just need to download all the QTE dependencies and try to compile itOriginally Posted by weirdfox
it would be nice if you give us some news now and then, when you achieve something interesting.
i'm also interested in running linux on handhelds
In fact I haven't tried running Qt apps on my handheld. It's not an easy task to collect all the QTE dependencies required to build it using a slo-o-o-w uplinkOriginally Posted by hansmbakker

that's a pity
what uplink is slow? your internet connection or the connection between your palm and your computer?
what has that to do with collecting the dependencies?
Internet connection. QTE requires qte , qt2 and qt3. Opie requires some more stuff like OpenEmbedded build system based on monotone and that stuff works awful on amd64Originally Posted by hansmbakker
Then I think we can't help you with that. Maybe you can open an internet site to collect money for a better connection like that british student did (pixels could be rented for ads)
Nah, I don't like the idea of selling pixels I'm fighting local admins to fix the routing so that old (and fast) uplinks become accessible againOriginally Posted by hansmbakker
and then you go qte programming again?
Sure, but I haven't started programming QTE yet. Just browsed some sources.Originally Posted by hansmbakker
How about the speed on these devices? I am very interesting. I had build qte/qtopia on some arm boards.Originally Posted by Farcaller
T|T3 (PXA261 at 400MHz) runs GTK+ applications very fastOriginally Posted by cavendish
Do you mean a Palm? Can a Palm run GTK+?
Yep, Palm Tungsten T3. Check http://hackndev.comOriginally Posted by hansmbakker

I visited the handhelds.org site earlier, but the familiar distro seemed to not be able to run well on Palms. Thank you for the link
