Which window-toolkit to use for embedded linux?

Question

Hi Friends,

I am using embedded-linux for device which has Arch ARMv5 Speed 266MHZ, vfpu and 32bit bus, 32MB 133 Mhz DDR Ram. can you tell me which windowing system should I use,

1).QT for embedded linux 2). Android. 3). Other!!

Well, I am using microwindows for last one year and not satisfied with it as it does not have BSP (Binary Space Partitionin) in its windowing system , No shared memory support for bitmaps. I think Microwindows is just optimized for memory-size not for speed.

So,Can you please tell me what is better choice for windowing system?

Thanks, Sunny.

Answer 1

Android is a Linux-based operating system, not a windowing system.

Answer 2

I don't have any idea what modern OS/Windowing system you could use on a machine with those specs. What are you using it for? From the Android direction I can tell you it'll probably be underpowered for your purposes. The G1 has 6x the ram and 2x the processor and it still isn't exactly snappy. I couldn't find any specs for QTEmbedded.

Answer 3

IIRC Qt should work well with these specs. It has a configuration cabapility where you define out parts of the framework you might not want (e.g. copy/paste), and should fit in just under 3Mb on an uncompressed filesystem with the most basic of feature set. It's canvas API has a BSP index traversal algorithm, but the latest approach (recursive) is much faster. With 32Mb RAM you might find it a bit limiting but again this depends on what you are intending to do. Qt has it's own windowing system that alleviates the need to run an operating system + windowing system; QWS. For more info, check out

Answer 4

Take a look at xynth. It's very portable.
