[05:46:50] <sirajperson> them**
[05:47:41] <sirajperson> I would like to be able to create my one TreeItem class that extends the TreeItem.
[05:53:24] <nitind> I take it you saw the part of the documentation that says you're not supposed to do that?

[10:03:08] <milestone> and i go wtf?
[10:07:36] *** skotisis has joined #eclipse
[10:08:56] <nitind> I believe it won't work with Galileo.  Helios or Indigo only.

[11:13:51] <QbY> Please forgive the newbie question.  How do I enable hints/code completion (where it provides me a list of valid commands as i type)?
[11:15:29] <ron> how to enable it or how to trigger it?
[11:15:35] <QbY> trigger i guess
[11:15:45] <QbY> i never see it, and i kind of need it
[11:16:09] <ron> ctrl+space
[11:16:39] <QbY> hrmm..  didn't bring up nothing..
[11:17:03] <ron> which editor?
[11:17:34] <QbY> Eclipse Java EE Indigo - Android SDK
[11:18:16] <ron> and you're editing a java file?
[11:18:34] <QbY> yes
[11:19:07] <ron> can you take a screenshot of eclipse and paste it? ~images
[11:19:15] <ron> ~image
[11:19:15] <Arbalest> Please upload your screenshots online and then paste the link back to the channel - http://imagebin.org/index.php?page=add - http://www.freeimagehosting.net/ - http://imagebin.ca/upload.php - http://imageshack.us/
[11:19:17] <ron> bah.
[11:21:33] <QbY> ron. http://imgur.com/QTu8i

[11:23:00] <platero> Hello
[11:23:09] <platero> how is everybody?
[11:23:15] <ron> super
[11:23:28] <platero> could anyone help me to understand how to refresh the contect of a treeview?
[11:23:41] <platero> i am reading some pages but i dont understand it properly
[11:23:46] <ron> swt/plugin development?
[11:24:05] <platero> i dont know how i can make my model system notify my treeview that it must be updated
[11:24:08] <ron> or rather rcp/plugin development?
[11:24:21] <platero> rcp/pluging development
[11:24:25] <platero> :)
[11:24:29] <ron> yeah, can't help with that, sorry.
[11:24:39] <platero> hehehee, thanks anyway
[11:25:02] <ron> QbY?
[11:26:06] <QbY> i just removed it
[11:26:55] <ron> okay
[11:27:22] <ron> now, add a new line in the onCreate method
[11:27:30] <QbY> k.
[11:27:47] <ron> type Str and then ctrl+space
[11:27:52] <ron> do you get anything?
[11:28:01] <QbY> yes
[11:28:17] <QbY> I will always have to do Ctrl+Spaace?
[11:28:24] <QbY> I can't have it always popping up stuff
[11:29:00] <ron> it'll popup automatically when you type . -> like myClass.
[11:29:07] <QbY> k.
[11:29:15] <ron> it doesn't make sense to popup as you type along
[11:30:02] <QbY> true, i don't mind it though
[11:32:43] *** busfahrer has joined #eclipse
[11:33:27] <busfahrer> Excuse me, in Subclipse, is there any way to change the URL that is considered the "root" of the repository? It currently regards a directory higher up as its root which I don't have access to, and that makes branching impossible, as it seems.
[11:34:42] <ron> did you look at the properties of the repository in the svn perspective?

[12:26:03] <platero> rcjsuen, could u point me to a good manual/tutorial/article to understand how to make my treeviewer update when some of my object is modified
[12:26:16] <platero> I dont know understand very well
[12:26:22] <rcjsuen> and don't PM ppl next time
[12:26:30] <platero> ok
[12:26:33] <platero> i am sorry
[12:27:37] <rcjsuen> tree viewer has update/refresh methods, call them when you object is modified
[12:29:23] <platero> So i have to call directly the treeviewer, there is not an system in eclipse rcp to notify that my object has been modified, right?
[12:29:42] <platero> I have to do it manually then
[12:31:04] <rcjsuen> use databinding if you want
[12:31:38] <platero> umm....
[12:31:45] <platero> ok, i am going to look for that then
[12:31:49] <platero> thank you

[15:00:44] <wfq> hi guys
[15:01:16] <wfq> in the past I had to use netbeans because I couldn't find a very good java pluging for using swing
[15:01:41] <wfq> is that solve now or it has always been solved and I am a bloody useless :)
[15:02:02] <ron> you're bloody useless.
[15:02:03] <ron> ;)
[15:02:07] <wfq> hahahah
[15:02:15] <ron> try the WindowBuilder Pro plugin for eclipse.
[15:02:50] <wfq> ron, thanks a lot
[15:04:12] <wfq> ron, can I use it for java applets as well?
[15:04:29] <ron> you shouldn't do java applets.
[15:04:52] <wfq> sorry, don't get it
[15:05:08] <ron> applets are the source of all evil and should be avoided.
[15:05:29] <wfq> :) well that is another issue but can I do it through that plugin
[15:05:40] <wfq> I'd hate have to switch to netbeans
[15:05:50] <wfq> *to have...
[15:06:00] <ron> I have no idea.
[15:06:21] <ron> basically, though, applets are just gui apps wrapped in an Applet class.
[15:06:28] <ron> so I don't see why there should be a difference.
[15:07:20] <wfq> well, I am not a javas expert but there is some. I just do not wish to have to convert my gui java application to applets. I'd prefer to have anything done directly
[15:07:42] <wfq> like setLayout (BorderLayout) to FlowLayout , etc...
[15:07:46] <ron> again, if you plan it wisely, there shouldn't be much of a difference.
[15:08:15] <ron> and if you avoid applets and use java web start, I think there's pretty much no difference at all.
[15:10:52] <ivarref> Hi all. is it possible to debug or get some information about what you see? e.g. there is a popmenu objectcontribution extension point, but is there a more general extension point for everything that is clickable?
[15:11:25] <ron> okay, what?
[15:12:21] <baedert> In my plugin, I'd like to have some custom/internal preferences. Where am I supposed to save a xml/txt/whatever file where I want to store those preferences?
[15:12:51] <nitind> baedert: http://www.eclipse.org/eclipse/platform-core/documents/user_settings/faq.html
[15:12:54] <ivarref> ron: for example for a given view.. how to get information about that particular view? to see where the code is actually running. I know it's not the best question. I'm just thinking about a very general introspection method
[15:13:21] *** mikewintermute has joined #eclipse
[15:13:26] <ron> ivarref: context, man. context.
[15:13:26] <nitind> ivarref: No.  You can use Plug-In Spy (Alt+Shift+F1) to get a better idea of what's in front of you, and pause the main thread to see what the UI is doing.
[15:13:33] <wfq> ron we'd need something in the browser
[15:13:53] <ron> wfq: do you, really?\
[15:14:12] <wfq> yeah, it is the first requirement
[15:14:29] <ron> wait, is it homework?
[15:14:35] <wfq> otherwiser I wouldn't even use java as I am not a java developer, but python or even c++
[15:14:40] <ivarref> nitind: thanks.. that's quite helpfull :)
[15:14:41] <wfq> no homework at all
[15:14:56] <wfq> this is a very real coputer vision and machine learning application
[15:14:58] <ron> is the requirement that it runs from the web or is it that it runs inside a browser?
[15:15:58] <wfq> the browser should be the launcher
[15:16:07] <ron> hence, java web start.
[15:16:28] <wfq> and it's a client-server application
[15:16:32] <ron> so?
[15:17:00] <wfq> don't know. what are the disadvantages of using java web start
[15:17:02] <nitind> wfq: If you don't want to write in it Java, why are you trying to write it in Java?
[15:17:03] <wfq> and why not applets
[15:17:20] <wfq> nitind, because our client is very complex
[15:17:26] <wfq> we need to analyse live streaming video
[15:17:36] <ron> wfq: because applets have quirks that are related to the browsers. java web start is just a java application has has got nothing to do with the browser.
[15:17:37] <wfq> and flash video player are not accurate enough
[15:17:47] <ron> the only thing you use the browser for is.... to start the application.
[15:18:12] <ron> it's just a way to inject your application to the user without the user having to install anything directly.
[15:18:15] <wfq> yeah but you will have to download application locally, don't you?
[15:18:38] <ron> it'll be download locally just as applets are downloaded locally.
[15:18:47] <wfq> well I was waiting for that answer
[15:18:58] <wfq> but we need to make sure the guy only uses web browsers
[15:19:12] <ron> but even with applets you can't do that.
[15:19:15] <wfq> no application dowloaded to the desktop and then run out of it
[15:19:24] <wfq> yes but the applet runs within the browser
[15:19:28] <wfq> it is simple
[15:19:44] <ron> okay, what are you trying to avoid?
[15:19:44] <nitind> And can only talk to the server it came from, iirc.
[15:19:48] <wfq> I can guess the java web start is something that uses the web just to download the app
[15:20:03] <ron> nitind: my apologies for keeping it off topic.
[15:20:11] <wfq> nitind, that is a good observation
[15:20:24] <wfq> and agree with it
[15:20:45] <wfq> so what does the guy connect for second time to our system must do after connecting the first time
[15:20:55] <wfq> open the browser and download the apps again?
[15:21:01] <wfq> *app

[15:44:50] <wfq> again :)
[15:46:10] <wfq> well, I tried some demos and I was asked for java web estart 1.2.2. I can guess that happened to me because I had JRE already but I imagine that for "virgin" matchines we can make it so that the client download JRE+Java web start at the same time, can't we?
[15:46:51] <ron> I'm fairly certain the JRE contains the JWS in it.
[15:46:57] <wfq> well, have to close this again as the chat client is java based and need to get closed to install java web start

[17:35:38] <Leonel> Hello there, I've been watching videos of GWT UI Designer and WindowBuilder, do you know if there is any tool like that for Python? I would love to make some fast little apps that way
[17:37:08] <ron> better ask on #python :-/
[17:39:41] <Leonel> ron: they anwered me about QTDesigner but I think they don't like "lazy people" much, this tool create an UI and then is tranlated to Python, not really bi-directinal.. so I'm trying my look somewhere else :P
[17:40:15] <ron> well, QT is not really python per-se afaik.
[17:40:28] <Leonel> I mean they didn't know what I was talking about when said GWT UI Designer, and they didn't seem want to talk about Visual Studio things
[17:41:18] <ron> well, I'm not sure.. never done python really.
[17:42:05] *** thecarlhall has joined #eclipse
[17:42:25] <ron> http://wiki.python.org/moin/GuiProgramming <-- have you looked under gui design tools and ides?
[17:43:39] <Leonel> ron: yes, they're all "make an UI and translate to code" things, I've installed like 20 different things yesterday, but nothing really "double click a button and code its click event"
[17:44:20] <Leonel> once you have your code, if you want to modify the UI you have to edit all your events again
[17:44:27] <ron> I see.
[17:44:38] <ron> well, time to dump python ;)
[17:44:58] <Leonel> yes, I think its time to learn Java.. :(
[17:45:40] *** aminpy has quit IRC
[17:48:34] <Leonel> its a pitty because it was such a nice language to learn programming, and I don't really have a lot of time to learn a new one
[17:48:51] <ron> what do you need to develop?
[17:50:04] <Leonel> I've been playing with web sites, and I wanted to try some small windows tools.. but it takes too much work to create widgets with just code
[17:51:10] <ron> there are many web frameworks for python.
[17:54:23] *** ddk_ has quit IRC
[17:54:56] *** ddk_ has joined #eclipse
[17:55:14] <Leonel> anyway GWT looks amazing so I'll try Java, I was just delaying it because it seems to take twice the code to do the same thing =P

[20:28:37] <sirajperson> hello all. I was wondering if anyone could help me with an swt problem. I would like to exted the TreeItem class to create my own treeItem. I pasted my src and the error messages that I am getting at http://mysticpaste.com/view/9464
[20:29:07] <sirajperson> extend***
[20:34:46] <rcjsuen> it means what it says
[20:34:51] <rcjsuen> the class is not intended to be subclassed
[20:42:21] *** ddk_ has quit IRC
[20:42:26] *** aminpy has joined #eclipse
[20:43:25] <nitind> sirajperson: For what is your subclass intended?
[20:43:37] *** _nor has quit IRC
[20:45:08] <sirajperson> I would like the treeitems to have special values to distinguish them from other treeitems. In particular I would like to be able to use the tree items as a graphical way of creating tags in an xml file
[20:46:06] <sirajperson> so if I have a tree item "TreeItmBtn" I would like it to contain a class variable "id"
[20:46:59] <sirajperson> But I don't seem to be able to extend the TreeItem class to be able to give it class variables upon instantiation.
[20:47:30] <nitind> sirajperson: That's what Widget#setData(Object) and Widget#getData() are for.
[20:47:32] <sirajperson> maybe there is a better way then trying to extend the TreeItem class?
[20:47:58] <sirajperson> hmmmm
[20:48:08] <sirajperson> sorry for being such a n00b
[20:48:10] <sirajperson> LoL
[20:48:50] <sirajperson> I will look up setData
[20:48:59] <sirajperson> thanks for giving me that hint.
[20:50:41] <sirajperson> can i use setdata to create more then one type of instance variable once i have instantiated a TreeItem?
[20:52:42] *** helindbe has joined #eclipse
[20:52:43] <nitind> There's another variation of those methods for that.  Check the doc on Widget.
[20:56:03] <sirajperson> thank you

[21:02:11] <sirajperson> thank you, thank you, thank you for telling me about getData and setData! nitind
[21:02:26] <sirajperson> that is exacty what I deeded. I can set more then one at a time.
[21:03:48] *** waza-ari has joined #eclipse
[21:06:00] <waza-ari> Hey all - i'm using eclipse pdt helios. Im using the smarty tpl-engine stored in a subfolder. In the "Problems" view eclipse announces some Warnings in the smarty folder. Can i somehow make eclipse ignoring them, thus not showing them at all? i already added that folder as "exclude" to the php build path in project properties. Any idea? thanks in advance
[21:06:58] <waza-ari> The reason is, i just want to see the warnings of _my_ code, not of some external code
[21:09:20] <nitind> Unless you mention what those warnings are, there's not much to be done.
[21:12:53] *** RenatoSilva has left #eclipse
[21:13:13] <waza-ari> nitind: these are some warnings in the php code which eclipse announces. since this is not my code, i dont care about the like "invalid text string at file..." in this particular subfolder
