Re: [maemo-developers] Best IDE for maemo development?
Hi there, that's an interesting question :-) I prefer to use vim and devhelp. I tried using Anjuta but it's too... basic :-) and Eclipse isn't very good for C development (I use it on a daily basis for Java development and currently I have to admit that Eclipse is getting really bad for Java as well). autotools, vim and devhelp proved to be the fastest way to learn the GTK API's and to actually do stuff without having a million other "features" getting in the way. -Original Message- From: Eloi Crespillo Itchart <[EMAIL PROTECTED]> To: maemo-developers@maemo.org Date: Tue, 21 Feb 2006 13:29:27 +0100 Subject: [maemo-developers] Best IDE for maemo development? Hi, A little survey about your development preferences: For the people that develops often on maemo, what IDE/set of tools have you found to be essential to this task? Anjuta? Emacs? Kdevelop? Eclipse? devhelp? ... It could be interesting to know which tools have you found to be more suitable for this task. It could also be interesting to know if you use them to develop maemo itself or userspace apps. And please, keep the flame wars low ^_^.

Re: [maemo-developers] Sketch like pointer movement detection
Hello, thanks for your helpful pointers but I have one doubt: if I invoke gdk_event_get() in my motion event callback, is it positive that all next events are going to be motion events? If those events aren't motion events, I'd be able to skip them but wouldn't I lose the skipped events? Furthermore, if I ask for the next event by calling gdk_event_get(), will my pointer motion callback be invoked later for the returned event? Thanks once again.

[maemo-developers] Sketch like pointer movement detection
Hi everyone, I'm developing a small app just for kicks and I want to have a drawing area similar to Sketch. I've followed the GTK tutorial, the Scribble example part, on how to detect mouse movement and translate that to a drawing. The thing is that compared to Scribble, Sketch is really slick because Scribble fails a lot of movements,probably because drawing to the screen is expensive, because the pixels only get drawn on screen with big intervals. I was just wondering if it is possible to improve pointer motion by having some other masks besides GDK_POINTER_MOTION_MASK? I've removed the GDK_POINTER_MOTION_MASK_HINT but it hasn't improved the drawing. I want to improve on Scribble, so I'm already thinking about alternatives like queuing all motion events and have a separate thread doing the drawing bits if that is the only way to have slick motion detection. Any insight is really appreciated. Cheers, Celso ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
Re: [maemo-developers] Application receives SIGKILL if executed through the menu
Hi Kalle, thanks for your insight. One more question though, in the service file, the service name should then be com.nokia., right? In related news, how can I suggest changes to the "new application howto" as to include this precious information?

[maemo-developers] Application receives SIGKILL if executed through the menu
Hi everyone,
I installed a small application I'm developing on the 770 and noticed
that it crashed a lot so the next thing I did was to install it as well
in the (x86) SDK and run it there. I noticed that the application also
crashed but only when I run it by using the menu entry.
If I run the application from the command line using run-standalone.sh
it doesn't crash. So I installed xterm in the 770 and also ran the
application from the command line and the results are the same: the
application doesn't crash if started on the command line.
Debugging the application in the SDK, the gdb results are:
Program terminated with signal SIGKILL, Killed.
The program no longer exists.
Any ideas about why does this happen?
I think that this may be related to OSSO initialization, so here's how I
initialize the application:
int
main(int argc, char **argv)
{
AppData appData;
gtk_init(&argc,&argv);
#ifdef MAEMO
ossoCtx = osso_initialize(PACKAGE,
PACKAGE_VERSION,
FALSE,
NULL);
if (ossoCtx == NULL)
return OSSO_ERROR;
#endif
load_resources();
create_gui(&appData);
gtk_main();
return 0;
}
Any comments are welcome.
Cheers,
Celso

[maemo-developers] fakeroot hangs
Hi everyone, I'm following the Maemo tutorial and I'm trying to build a package but fakeroot hangs indefinately. I'm running SDK 1.1rc5 and I was wondering if anyone ran into this problem as well and if so, how did you get around it.
