[sugar] Needs for Browse
I was working w/ Trinarayan today on running flash activities on the XO and we came upon a lot of features we need in Browse. For the moment we are using firefox 3 but would like to use Browse instead. 1. Display flash by default. A lot of existing educational resource use flash. Some people don't like turning on flash because it slows down a lot of pages. We want it turned on because most of the sites of educational value either use flash heavily or not at all. We don't care if www.tv.com is slow or Myspace takes a long time to load. 2. Tabs -- we need them It takes too long to alt+tab between multiple instance of Browse. I don't think kids will be confused by multiple tabs but we can test this out soon. 3. Browse doesn't find Flash's settings.sol file. Flash needs permission to open html files on the local machine. We intend these files to be in the flash activity bundle and this permission has to be set in settings.sol While we are developing some of our activities in flash, because we can do it faster than in EToys. We are still doing activity development with EToys, just not all of it in EToys. It is impossible to hire someone w/ Squeak experience in Nepal and very time-consuming for them to get up-to-speed. Thought for the day: Flash is important! The folks more likely to develop learning activities will come from a webdev/graphic design background and less likely kernel hackers. The former type are quite familiar w/ Flash, html, and photoshop. As much as we would like them to use Squeak or Python to develop activities, it's gonna take a while. Let's not shut them out by not supporting flash well. Also, countries that have invested heavily in IT already have typically also invested heavily in flash. ___ Sugar mailing list Sugar@lists.laptop.org http://lists.laptop.org/listinfo/sugar

I'm curious if anyone knows of ways in which similar functionality has been implemented elsewhere. In general I'd like some advice about the best place to implement this feature. Just put a passive grab on the keys to receive the key press event and then, depending on what you mean by scrolling: - mouse wheel emulation put a (sync) grab on the mouse and use XTestFakeButtonEvent on buttons 4/5/6/7 for to scroll. you'll need to mess around a bit with XAllowEvents, but it should work. - viewport scrolling XWarpPointer seems the only way, I don't see any other callers for xf86SetViewport that could be used directly.

I read through the license a couple months ago and if I can recall correctly, an organization can distribute copies of flash within its LAN. Technically I am the sysadmin for the schools and they are w/in my LAN. I don't ship flash or post an XO build that includes flash on a publicly accessible web server.

I also won't argue tabs or no-tabs at present (though the initial designs did have tabs, there were some concerns about them as well). I'd second Tomeu's comment; the new Frame design as well as the new alt-tab behavior are *much* better than before. Also, in addition to the standard alt-tab, I want to add alt-backtick as well to cycle only through all instances of the current activity. (ticket #7335) This is specifically to facilitate this use case, would make switching much more direct. - Eben ___ Sugar mailing list Sugar@lists.laptop.org http://lists.laptop.org/listinfo/sugar
Re: [sugar] flash (was Browse Needs)
Well, adobe is moving more and more towards open source, hence their stance on AIR and Flex, which are both completely open source as far I as understand... I know from the ubuntu devs that they even asked whether they can help with the creation of a totally open source flash implementation... (flash not gnash) How does Flex differ from Flash? would it not be possible to do Flex instead?

If you can help, feel free to make a start looking at packaging GG in an RPM for the XO. This needs to happen, and that in itself doesn't need many decisions or waiting for anyone.

[sugar] Question about internationalization on sugar-jhbuild
Hello All, I'm trying to set up some simple internationalization on a sugar activity but am running in to problems. I am specifically using sugar-jhbuild and launching it with 'LANG=es ./sugar-jhbuild run' command when I want to test my internationalization out. Here are the steps I have followed (I used http://wiki.laptop.org/go/Python_i18n and http://wiki.laptop.org/go/Localization/Testing to guide me): 1. First, I created a directory within my activity (a simple shell fo an activity which I have called Annotate.activity) called 'po' and I went in to that directory. 2. In Annotate.activity/po, I created a POTFILES.in file and put the following text: encoding: UTF-8 annotateactivity.py 3. I launched sugar-jhbuild and went in to the terminal, where I ran 'python setup.py genpot' from the Annotate.activity directory. This generated an 'Annotate.pot' file. I went in to Annotate.pot and added some translations for strings that I knew would need translating in my program (one specific one was a from a print statement where the string is wrapped in _()). 4. Still in sugar-jhbuild's terminal, I ran 'msginit -l es' which generated a file called 'es.po'. 5. finally, I did 'msgfmt -o ../locale/es/LC_MESSAGES/ org.laptop.AnnotateActivity.mo es.po' to generate the mo file and place it within the right directory for spanish (the directory path is similar to the one I found for Web.activity, whose translations are working fine). After doing all this, I restarted sugar-jhbuild by using 'LANG=es ./sugar-jhbuild run' . I can see other activities have text translated, but my activity is not translating the text that I wrapped in _() and was printing out. I checked the source file and I am using gettext (importing it as _ and then using the wrapper in the print statement I want translated). Someone suggested trying to do an strace to see what was happening. I did this and found the following in the portion of the log where it has any reference to the string I want translated: 1. stat(/home/fanwar/sugar-jhbuild/sugar-jhbuild/install/share/sugar/activities/Annotate.activity/locale/en_US.UTF8/LC_MESSAGES/ org.laptop.AnnotateActivity.mo, 0x7fffa41f75d0) = -1 ENOENT (No such file or directory) 2. stat(/home/fanwar/sugar-jhbuild/sugar-jhbuild/install/share/sugar/activities/Annotate.activity/locale/en_US/LC_MESSAGES/ org.laptop.AnnotateActivity.mo, 0x7fffa41f75d0) = -1 ENOENT (No such file or directory) 3. stat(/home/fanwar/sugar-jhbuild/sugar-jhbuild/install/share/sugar/activities/Annotate.activity/locale/en.UTF8/LC_MESSAGES/ org.laptop.AnnotateActivity.mo, 0x7fffa41f75d0) = -1 ENOENT (No such file or directory) 4. stat(/home/fanwar/sugar-jhbuild/sugar-jhbuild/install/share/sugar/activities/Annotate.activity/locale/en/LC_MESSAGES/ org.laptop.AnnotateActivity.mo, 0x7fffa41f75d0) = -1 ENOENT (No such file or directory) 5. write(1, hello world should be translated..., 33hello world should be translated 6. ) = 33 1 stat(/home/fanwar/sugar-jhbuild/sugar-jhbuild/install/share/sugar/activities/Annotate.activity/locale/en_US.UTF8/LC_MESSAGES/ org.laptop.AnnotateActivity.mo, 0x7fffa41f75d0) = -1 ENOENT (No such file or directory) 2 stat(/home/fanwar/sugar-jhbuild/sugar-jhbuild/install/share/sugar/activities/Annotate.activity/locale/en_US/LC_MESSAGES/ org.laptop.AnnotateActivity.mo, 0x7fffa41f75d0) = -1 ENOENT (No such file or directory) 3 stat(/home/fanwar/sugar-jhbuild/sugar-jhbuild/install/share/sugar/activities/Annotate.activity/locale/en.UTF8/LC_MESSAGES/ org.laptop.AnnotateActivity.mo, 0x7fffa41f75d0) = -1 ENOENT (No such file or directory) 4 stat(/home/fanwar/sugar-jhbuild/sugar-jhbuild/install/share/sugar/activities/Annotate.activity/locale/en/LC_MESSAGES/ org.laptop.AnnotateActivity.mo, 0x7fffa41f75d0) = -1 ENOENT (No such file or directory) 5 write(1, hello world should be translated..., 33hello world should be translated 6 ) = 33 1 2 3 4 5 6 stat(/home/fanwar/sugar-jhbuild/sugar-jhbuild/install/share/sugar/activities/Annotate.activity/locale/en_US.UTF8/LC_MESSAGES/ org.laptop.AnnotateActivity.mo, 0x7fffa41f75d0) = -1 ENOENT (No such file or directory) stat(/home/fanwar/sugar-jhbuild/sugar-jhbuild/install/share/sugar/activities/Annotate.activity/locale/en_US/LC_MESSAGES/ org.laptop.AnnotateActivity.mo, 0x7fffa41f75d0) = -1 ENOENT (No such file or directory) stat(/home/fanwar/sugar-jhbuild/sugar-jhbuild/install/share/sugar/activities/Annotate.activity/locale/en.UTF8/LC_MESSAGES/ org.laptop.AnnotateActivity.mo, 0x7fffa41f75d0) = -1 ENOENT (No such file or directory) stat(/home/fanwar/sugar-jhbuild/sugar-jhbuild/install/share/sugar/activities/Annotate.activity/locale/en/LC_MESSAGES/ org.laptop.AnnotateActivity.mo, 0x7fffa41f75d0) = -1 ENOENT (No such file or directory) write(1, hello world should be translated..., 33hello world should be translated ) = 33 1.
