07:05.46 jasvir hi starseeker. I have some query about qged. From gui, I can see that qged can read objects but unable to draw. I have read code but not that deeply. Can you please tell me that what type of work is already been completed to start drawing. Like if I create an OpenGL widget in qt, what type of work will we have to do next?

15:00.52 starseeker jasvir_: no work has been started on drawing
15:01.26 starseeker you'll have to provide the opengl context to libdm, and study MGED's mouse bindings and figure out how to re-create them in a Qt widget
15:02.44 starseeker you'll need to read the code quite deeply (qged, mged and libdm) to understand how all the pieces will need to fit together, as well as doing some new design work on a Qt widget

18:38.28 starseeker jasvir: I'm not sure what that code specifically is for - the idea of the Qt libdm layer originally was to use Qt itself (the Qt canvas) rather than OpenGL as a drawing layer - in essence a portable version of our X24 libdm backend
18:39.32 *** join/#brlcad Ak7 (Akshay@59.177.229.3)
18:39.40 starseeker jasvir: that's a bit orthogonal to the qged effort. I expect the dm-osgl backend is probably going to be best suited for Qt integration at the moment, since it is intended to be cross platform
18:48.22 jasvir starseeker: Oh! That's why I was confused about from where I should continue. I thought I am supposed to use dm-qt but it was using tk somehow and it made some spaghetti images about code in my mind.
18:49.03 jasvir I have already gone through dm-ogl

20:07.25 brlcad jasvir: that's fishing, please don't fish :)
20:09.48 brlcad what I mean by that is you're asking someone else to do work that you are perfectly capable of doing yourself (at least as far as you have expressed in terms of technical content)
20:10.00 brlcad if you have a specific technical question about mged or libged, you should ask that
20:10.11 *** join/#brlcad pujani (~pujani@101.60.178.118)
20:11.17 brlcad asking to be briefed or guided is not productive for starseeker or anyone else except yourself, and any response may not even help you with what you really need to know
20:11.49 brlcad that's why you should ask questions, and ask smart questions, not ones that are trivially found by searching the code or (worse) a quick google search
20:12.36 brlcad make sense?
20:13.37 Ch3ck hi brlcad
20:15.10 brlcad hi Ch3ck
20:15.42 brlcad starseeker: seeing approximate ~13% build time reduction on linux with the doc changes
20:16.18 brlcad across a cycle of cmake+make+make+make clean
20:16.58 Ch3ck brlcad: I try running mged from my Fedora distro and I get only the text editor, no GUI
20:17.07 Ch3ck I don't know if it's something I did wrong
20:48.30 jasvir brlcad: I am not asking to explain the code but I assumed that src/mged is all that is related to MGED and I was reading the code but I suddenly realize that there is libged and I got a bit confused. I wanted to know about it. Both are having functionalities that are related to drawing but all I get that src/mged is related to user interactions. I think I have used wrong words. Thanks for pointing it out.

20:56.12 ``Erik jasvir: it used to be all mged, but we've tried to split the 'controller' type stuff to libged/ and have mged/ be 'view' type stuff. The End. :)
20:57.17 jasvir ``Erik: Thanks erik :)
21:02.25 brlcad Ch3ck: cmake almost certainly failed to detect X11 developer libs
21:03.24 brlcad jasvir: wanting to know about it is asking to explain... :)
21:03.40 brlcad providing context like you just did is much better and not as open-ended
21:04.21 jasvir brlcad: Yes I got. I used wrong words. Thanks
21:04.38 brlcad I strongly encourage you to do a search on "smart questions" and read the paper by ESR (in full) .. it's very insightful on how to ask questions that don't leech off others
21:05.19 brlcad jasvir: I'm not sure you're getting the point -- what were the right words?
21:05.54 brlcad even with your detailed explanation, that's better but you still didn't ask a question
21:06.11 ``Erik !notify ask
21:06.12 Notify Questions in the channel should be specific, informative, complete, concise, and on-topic. Don't ask if you can ask a question first. Don't ask if a person is there; just ask what you intended to ask them. Better questions more frequently yield better answers. We are all here voluntarily or against our will.

21:08.08 jasvir brlcad: my rephrased question was not good enough to convey my thoughts?
21:08.35 jasvir brlcad: I understand what you are trying to say.
21:08.48 brlcad e.g., instead of "brief me" or "I want to know about XXX", you could have asked something like "I see mged and libged have related functionality, but how do they interact?"
21:09.41 brlcad no, your rephrased question was not good enough .. because you didn't actually ask a question :)
21:13.49 jasvir brlcad:
21:13.57 jasvir I got it
21:14.11 jasvir will take care of it in future.
21:14.18 brlcad no worries
