[Mathmagic-devlopment] First release of calculator.

[Brian W. <bh_...@ya...>]

Ok its only a console app at this time, but I figure
you guys could help me out and see how it works, and
how the code could be improved.  Also I have started a
new sourceforge project to house just this part of
math magic at http://sourceforge.net/projects/mmcalc
and you can download the latest stuff, and add bug
reports for it.  So please tell me what you think.

[NAYANI A. <nay...@ya...>]

Hi guys,

	we got to release our code of matrix modules atleast
by 25th. Filipe: as u are free, please remove the bugs
from my code. I am giving you this job as you have to
get familiar with gnome. The major bugs U got to
remove is disable back button in all pages, decrease
the size of the entry boxes, and on selecting finish
button in the last it should start the druid all over
again. Experiment with the code I gave u, I have added
some docs to the code and created html docs using
doxygen. I will give this code tomorrow.

B:
	The functions which I would like to see are:

	X to the pow Y,
	Variable Memory,
	thats all for now.

					Abhi.

Base conversion is good, I will do that at the end.

Yes for GPL, all you have to do is say its GPL in the header, and include
the actual GPL in the tarball.  There is no registration.

Hi,

A little suggestion, the conversion between decimal/octal/hex.
Say it it's easy than make it ;-)

Now, i must converted my fractal program using SVGALIB to GTK with
drawing areas.

A little question, just for my information, about GPL and our project.
Is that enough to write the text of GPL in ours programs (like Filipe's
code) or we must registered the project.

[Mathmagic-devlopment] Calculator functions.

[Brian W. <bh_...@ya...>]

Well I have gotten to point where I can easily add
functions.  Not sure yet about associativity though, I
will have to think about that.  I have included below
a listing of mathematical functions, please add any
you think would be cool.  If anyone wants to try it
out let me know and I will send the code out, and tell
me how it looks.
Brian

Functions:

ADD
subtract
Multiply
Divide
negate
cos/sin/tan
arc cos/sin/tan
hyperbolic cos/sin/tan
exp
absulute value
mod
ceiling
floor

power
x! <-- I forgot what is this called?
ln
log
sqrt
inverse

[Mathmagic-devlopment] Mainconsole

[Alain M. <ame...@ul...>]

Hi,

Here is my second version of the mainconsole which use toggles buttons.
Tell me what do you think about.

Re: [Mathmagic-devlopment] I'm unemployed

[Brian W. <bh_...@ya...>]

You could help me by writing a short bit of C code that tokenizes a string
such as "3.2+cos(24.52-sin(2.25))".  Just make it so it outputs it like
3.2
+
cos
(
24.52
-
sin
(
2.25
)
)
That would save me a bit of time.
Thanks.
Brian

I could probably use some help when I get to the part where I am adding
functions to the calc, but I am not there yet.

Hello!
If someone needs help i can help.
I finished the first version of the matrices funtions.
The interface is not very beautifull but it can be worked out.
The important thing is that IT WORKS.
I think i have a bug in my Multiply function, but i don't know how to multiply matrices do if someone could tell me if the program is outputing the right answers it would be a great help.
You don't need to find the bug. Just tell me if the results are right.Now i will try to learn gnome and help anyone who wnats my help.

[Mathmagic-devlopment] Status update.

[Brian W. <bh_...@ya...>]

Hello all,
Well I know you probably forgot that I was working with you on the math =
project.  Well it is taking a little longer that expected to make the =
calculater, and I am glad to report I was just able to add 2 numbers on =
the command line.  Ok so I have a long way to go, but the structure is =
now there.  How do I change my percentage done on the task list to 5%?  =
I figure I will get a full featured comand-line calculator that has lots =
of functions, and allows you to enter an entire expression at once, and =
then tie it into a Gtk+ frontend.  So I just wanted to check in with you =
all, and say hello.

[Mathmagic-devlopment] Druids and everything else.

[NAYANI A. <nay...@ya...>]

Hi,

	The best resources you can have when programming with
GTK+ & GNOME toolkits are the reference guides. You
can download them from developer.gnome.org/docs/api.
You should get all the docs there (
gtk,glib,gdk,libgnome etc.) and there are excellent
tutorials in the doc directory itself (like GGAD etc.)
If it is not possible to download all these stuff you
can find similar docs in /usr/doc/gnome-libs-devel/.
The thing you need to know about a druid is it is
mostly automated. It needs to be put in a toplevel
window of its own.There are three types of pages it
can hold, druidpagestandard - this has an empty vbox
in which we can keep any of our widgets,
druidpagestart(or first :)) - this page has a disabled
back button and we can display any text in the center.
druidpagefinish - similar to first, but it has got a
finish button instead of next. The druid automaticaly
handles the next and other buttons if we don't handle
the signals. There are four signals we can handle
"next","cancel","back","finish". you can connect a
callback to it ,do your function calls and then
display the next page using the func
gnome_druid_page_set(). For more info see the docs
--its easy. I used glade to do the following - create
the toplevel window, set the title, create druid with
4 pages. set each pages heading,logo. set the first
pages intro, create an hbox for the second page and
embed a label and entry widget. that's all! save,
build and delete the .glade file. The changes i did to
the main interface file are at the bottom separated by
****.
This style is really good and I would like it if you
can get used to it as well :).

				Abhi.

PS: I actually downloaded the whole
developer.gnome.org :). (wget -cr --tries=0 -nc
http://developer.gnome.org)
It comes to arround just 25Mb of high quality data.

Me too, what's this druid story, a Glade like ?

I think that's a good way.....with Glade we have 10.000 generated files
for a simple windows... not very cleany.

> i will continue to design in pure gtk :).

Filipe:
good work, i try to call them from the mainconsole.

Abhi:
I've problems to compile youy code, it's because some Gnome packages are
not present on my system..... i think.
New mainconsole version for monday with toggle buttons.

Re:[Mathmagic-devlopment] Forgot to send the code!!

[Filipe M. <fil...@po...>]

Hello Abhi!!
I'm very sorry for my mistake,it will not happen again.

I think that druid is less flexible, but i agree with the problem of being sinked in windows. But i never done anything with druid. Were can I find a tutorial about druid.
I already looked at your code but dind't understood it.
I can try to make the gtk funtions for the other funtions but i can't produce the interface because i don't know how to work with a druid.
The problem with druid is that i can't have many functions opened at the same.
If you could solve that problem and write an interface that is as flexible it would be great.
I will try to do the new functions with gtk, then learn druid, and then, maybe, write the code with druid.
I will send the new code whithin the next days.
During this days you may try to convert me to the druid interface or i will continue to design in pure gtk :).
I will also try to fix your problem.

Bye!!

[Mathmagic-devlopment] New code that includes inverse of Matrix

[Filipe M. <fil...@po...>]

Hello!
I've done this code in the last few days.
It can do 3 of the 4 functions.
It's not a very pretty code but it's not that difficult to undestand.
I used the almost unchanged Abey's functions for the math work and the cb_input functions.
Tell what you think of the code and what you want me to do.
To compile read the header of the *.c file and follow the instrictions ( i'm still not very confortable with glade). 
Bye!

[Mathmagic-devlopment] Check it out !

[NAYANI A. <nay...@ya...>]

Hi Guys,

	I didn't get any reviews of my code so I concluded
that you didn't like it. So, I am sending you guys
another sample which is more complete and quite good.
There are only a couple of bugs which have to be
ironed out. I need to know what you think of it fast
!!

Alain:

	The console you designed produced modal dialogs. Due
to which the user cannot open more than one function
at a time. Can you change your code to just include
menu on the menubar & use toggle buttons for
functions. The idea is to give the user the
flexibility to hide or show the buttons representing
functions . As long as the button is toggled , the
function is shown otherwise it is hidden.If my view is
still not clear, ask doubts, in the meantime review my
code.

			Abhi.
