Release of Calculator Calcoo

[yokos]

[04/25/2008] v.0.2.1 is out. It's v0.2 + pixbuf-loaders installation, which solves the app loading problems as discussed below.

Calcoo is a RPN and algebraic scientific calculator.

Features are as listed on official Calcoo homepage:
# both RPN and algebraic modes
# bitmapped button labels and display glyths
# undo/redo
# copy/paste interaction with the X clipboard
# two memory registers with displays
# displays for Y, Z, and T registers

Calcoo opens as a window on iLiad's screen. So you can scribble in pdf & calculate at the same time. You can move Calcoo's window with stylus on screen.

I tweaked the files b_main.c, b_settings.c & b_info.c to get Calcoo in it's own window. This is discussed below. "Settings" (!) & "Info" (?) dialog open a 2nd window. Have a look at the screenshot.

You can find the src on my projects page.
official Calcoo homepage: with versions for Linux, Windows & Mac.

[2007/10/12]: There is a problem. Calcoo doesn't start anymore. I will work on it.
[2007/11/03]: Sorry for the delay. A new version calcoo.iLiad.0.2 is out. Now with an installer. I tested it on CF/main memory.

The only working ways to close the Calcoo application are:
# reset iLiad,
# connect iLiad via USB to PC, this kills Calcoo.
Heh, it's a beta. It's just a "Hello world of MR's developer community".

Well, all buttons of Calcoo are working. If this no-exit-button is solved, it' will be a tiny calculator for iLiad.

Why there is no normal exiting of program?
Because I'm a newbie to porting.
More in detail:
# Calcoo hasn't got a menu, where we could choose "close app" like in other programs.
# Calcoo starts without window, therefore we can't see x-button in top bar.

Solution of known crux:
# Create a "exit-button".
# Get Calcoo started as a window.

Cool.

It might solve your problem if you made the window manager think it was a dialog box instead of a regular application. That should give you a close button and clean up all that white space.

[Adam B.]

gtk_window_set_type_hint (body->main_window, GDK_WINDOW_TYPE_HINT_DIALOG);

Adding the above in line 51 or so of src/b_main.c should do the trick.

Oh, I was searching the GTK Reference Manual.
Cool, that's so easy. I will try it at home later. Working Day is over here in Germany.

That's where I found it myself.

Glad I could help. This porting stuff really isn't as hard as it looks...

Interesting that the old "main window as a dialog box" also works on Linux. It's a standard "trick" that we use in Windows programming, too, that gives you a lot of functionality "for free".

It's especially handy when our window manager (matchbox), removes window decorations in order to give it more of a "tablet" feel.

What do you gain by doing that in Windows?

[HarryT]

Two main things:

1. You can design your dialog box with the very nice "drag and drop" editors that development environments like Microsoft's Visual Studio provide. On a "main" window you have to position everything with code, which is a lot more work. (For the purists, that's not strictly true, but it'll do as a first approximation)

2. At runtime, you get "for free" a standard keyboard interface, with "Tab" moving you from control to control, and "hotkeys" to jump directly to specified controls. For non-dialog windows, you have to do all that yourself.

Those are the main benefits.

Ok, Calcoo is now working like it should do.
I have attached the new binary in post #1.

[yokos]

I'm sorry, I wanted to edit post #1 but got a reply.

Will this need to be installed on a card or can it be run directly from the Iliad?

Just extract the included directory "Calcoo" to a place [CF, iLiad's memory, etc] you want to use. You need ~12 MB of free space, more than 90% of that are needed for the libraries. Maybe I should learn this ipk-think [-> Adam B.'s installation method] to get rid of these duplicates of libraries for every appl.

Hmmm ... in that case, I can't get it to work. The Calcoo window pops up briefly, then disappears again. Gnuchess runs fine from the same directory on the Iliad. Dang it ....

Same here, i am not able to run it, it seems to pop up very fast, but then its gone.

I confirm this. My Calcoo doesn't seem to be compatible to 2.11 with submitted libraries.
I get a "GdkPixbuf-WARNING" & "segmentation fault". Odd. I will work on it.
