| 03:43.28 | gkwhc | Hi, Im very interested in writing code on embedded linux for a touchscreen to recognize gestures such as a flick, to quick scroll through a page. Where should i look to get started? |
| 03:55.30 | MonMotha | gkwhc: most of this code has probably been written for you in various libraries. Which ones you'll need will depend on your application and what frameworks it uses. |
| 03:58.04 | gkwhc | MonMotha: oh. my application is fairly simple - its for the openmoko phone. i'd like for it to recognize gesture like a circle, and it would lock the screen by executing slock or a similar program |
| 03:58.37 | MonMotha | gkwhc: I don't know much about the frameworks used on openmoko, but my understanding is that they're fairly complete. |
| 03:58.59 | MonMotha | you should probably attempt to work within that framework |
| 03:59.17 | gkwhc | like xorg's tslib? |
| 03:59.24 | MonMotha | does it use that? |
| 03:59.29 | MonMotha | (it would make sense) |
| 03:59.42 | gkwhc | i think so |
| 04:00.10 | MonMotha | I wouldn't be surprised if there's a "gesture" library on top of that already. You'll also need to handle however they handle daemon type things. Given the nature of the system, there's probably something special. |
| 04:00.30 | gkwhc | hopefully i can find some documentation on it |
| 04:00.41 | MonMotha | I'm sure there's an openmoko developers website |
| 04:00.49 | MonMotha | probably with copious amounts of documentation |
| 04:01.56 | gkwhc | yeah |
| 04:02.10 | gkwhc | ill look into that. thanks MonMotha |
| 04:02.24 | MonMotha | I could tell you how to do this on a "bare" xorg system, but it's probably darned near irrelevant on openmoko |
| 04:03.16 | gkwhc | MonMotha: would you mind giving me a general idea of it? |
| 04:04.07 | MonMotha | it's a program that gathers touchscreen input via tslib, recognizes the gesture of your choice, when it sees it locks the screen by method of your choice (which could be as simple as exec'ing xlock or similar) |
| 04:04.13 | MonMotha | and optionally daemonizes itself |
| 04:04.47 | gkwhc | mhm |
| 04:04.50 | MonMotha | of course, that totally ignores just about every service on a modern linux system, desktop or "highly featured" embedded like a phone would typically be |
| 04:05.11 | MonMotha | I'm sure that "properly" locking a GNOME session involves dbus, for example :) |
| 04:05.31 | MonMotha | (mostly because EVERYTHING on GNOME seems to involve dbus...) |
| 04:05.41 | gkwhc | then it gets complicated quite quickly |
| 04:06.03 | MonMotha | dbus is ugly |
| 04:06.38 | gkwhc | i have no experience with it |
| 04:11.12 | MonMotha | For your sanity, I hope things stay that way :) |
| 04:18.52 | gkwhc | haha thanks |
