Since every computer that I run a GUI has Linux, I find myself using the default Calculator when figuring sales tax, or any other time I need a quit calculation. The problem is, the default calculator that comes with Xorg looks like it came right out of the early 80's. With that in mind, the aim of this project is to make a much more graphically pleasing calculator as an alternative for the Linux environment.

Omni Linux

Currently on the source forge page, there is at least one open position, & there will be more as the project matures.

Thank you for your interest.

Do you have any screen shots? I don't have Linux, so I can't test it~ I'd love to see it though

[no2pencil]

No screen shots yet. I'm still working on the engine. I've got the four main math functions down, add, subtract, multiply, & divide. Now I need to get decimals working. Once it's usable, then I'll work on the GUI.

While it isn't set in stone as the graphical library, I have started working with OpenGL, & have released a graphical version (with a lone screenshot). While the functionality is there, I have no image of a calculator, so you'll have to pretend for now (lame I know!)

You can use F3 for addition, F4 for subtraction, F5 for multiplication, & F6 for Division. Again, once there is an image, this will all be easier. Lastly, you use enter to get the result.

If anyone thinks they can offer some graphics, please do so. I would like to eventually make this project skinable, so it'll be community friendly as well as customizable.

I think this project would be fun and would like to help, although my opengl experience is nonexistent. I am also curious as to why you are using ints instead of doubles or using asm for the calculations instead of simple c operators.

No specific reason, just to get started.

I like passing between assembler & C, but nothing is set in stone.

Would you be interested in an equation parser? And if so, is C++ ok?

No2 - What are your feelings on GTK

[no2pencil]

I never really cared much for projects made with GTK. Since I don't run Gnome I'm always on the wild goose chase for the latest GTK libraries & toolkit which almost always requires older dependencies or for some other reason won't run on my system. I spend hours downloading & installing packages which I either end up removing or they don't boot well with my existing libraries.

[GWatt]

I'm pretty sure the answer is no, but is the omnicalc really supposed to look like this?

[no2pencil]

...that's as far as I've gotten with it.

I don't do graphics & by don't I mean can't!

So I have the graphical mapping done (so the program is functional), & it can be altered to.. well I guess any image that someone would like to present, & then I can load.

[GWatt]

You wouldn't happen to like QT any better than GTK, would you? and my offer for a parser still stands. It's mostly complete, too. Just some parenthesis stuff to work out.

P.S.
The reason I'm offering a parser is that it's much easier to see what's going on if you have a multi-step equation. You can also get rid of the mess of buttons that many software calculators have.

I would be extremely interested in any contributions that you decide to make!

I apologize for not seeing it before, in your previous post.

While I've never heard of QT, I am open to any graphical means of this project. It is my preference not to make it in GTK, since I don't use Gnome, however if it must be done that way, eh, fine.

[Nykc]

NO it don't need GTK I was just looking for some graphical libraries. QT would probably be the better choice anyways.

OpenGL isn't really the right library for what you're trying to do. There is a C++ library called GLUI that has some of the UI components you would end up recreating in OpenGL. I've never used it though, and for something like a calculator I'm not sure I would want to.

GTK, Qt, or FLTK are probably your best choices. As long as you stay away from Gnome/KDE features, GTK/Qt should be pretty lightweight. I've never used FLTK, but I've read a little about it and it sounded nice.

The reason that xcalc looks "old" is because it is old, and because it uses whatever toolkit that Xorg comes with so it really doesn't have many dependencies.

--------------------------------------

My input: Make it easy to enter equations in with the keyboard. I hate applications like the Gnome calculator that try to make you learn shortcut keys for different functions. I would like to be able to type something like sqrt(100)+log(100) and get an answer.

You might want to consider writing a graphical frontend to GNU Octave (which is what I currently use as a calculator). It's essentially a OSS Matlab clone [not that I have ever used Matlab ].
