Calculator, Opera application V1.0 Aug 14, 2006 5:40:58 PM

A scientific calculator with changable settings.


Latest Changes:
- Fixed the Teal skin, it looks now better
- Font changing now affects the buttons as well!
- Everything evaluated is now sent to another text field. This field can't be modified. To get evaluated code, select it with the mouse, and click on the right mouse button and select "Copy"
- Added the Fuchsia skin
- Set the Calculator title and the toolbar buttons to the top and rewrote it. This means the button positions do not shake anymore while changing views :wink:
- The button graphics are redrewn! They are now similar to each other as well.
- The colors change into yellow when hovering buttons
- Button texts are now in bold

See the Calculator itself to see the full Changelog.

"malformed" in opera 10 beta 2 USB build 1642, the entire row of the "C" key (clear) is cut off, and when you hit clear, it "disfigures" the widget again cutting off the other side

Why is it opague? Makes it very hard to read unless it's against a solid, dark background. Also, far right column of buttons are cut off. Some minor tweaks, and this will be a nice calculator.

Wow!
I love it! Thank you soooooooo much!

But, the full width doesn't show up. I can't see the buttons in the right (5th) column, where the Red one is.
I was thinking: hmmm....where's the arrows to make the sides wider so all the buttons can be seen? :frown:

Oh well..............
Thanks again.

How about a 10-key function calculator with an on-screen tape??

I'm gonna make big updates into this when I've got time :smile:

Here are some:
- Linux support (no transparency at start)
- move all apparence related config into one tab and have space for real config
- have configs saved

Plus I'm also planning a whole new UI... :wink:

Nice stuff aleksanteri. Very simple easy to use and config.

Ok I fixed that PI*PI bug but the E error seems to be very hard... perhaps I should use str.replace with str.search.

By aleksanteri , # Oct 12, 2006 9:16:27 PM

I know... that's a bug that has been bugging me. I don't know what's the matter with that. Also the widget seems to replace only one occurrence of a constant.

if I type
PI*PI
it ends up in a JS error. looks like this seems to be related to str.match();

I'll try to figure these out.

By aleksanteri , # Sep 30, 2006 7:45:02 AM

well if I type

3e-5 / 10

to the entry field and hit enter, it writes

3e-5 / 10E

and the out put is

2.9206095999639496e-8

I *think* that's not how it should work.

EDIT: even if it thinks that E is the Euler number (2.71828183) the output doesn't seem to have anything to do with reality?

By WildEnte , # Sep 29, 2006 10:40:24 PM

OK version 1,5 is released (a while ago), comment me what you think!

By aleksanteri , # Sep 16, 2006 8:03:42 PM

: Click on the input/output screen with your mouse and the keyboard should work. It's a normal textfield that is just styled.

Hmmmmmm, I've been adding more features to this so I might release another update.

By aleksanteri , # Sep 8, 2006 12:58:59 PM

great !
but unfortunatelly hard (impossible ?) to use with keyboard...

By Fredb , # Sep 7, 2006 10:01:06 PM

This might be hard to believe but the calculator was originally like this

By the way, it never worked p:

By aleksanteri , # Aug 30, 2006 9:48:25 PM

Very nice one, I will get that one to the next release

Edit: Input type="range" ??? I didn't know there was that kind of thing

By aleksanteri , # Aug 21, 2006 1:42:19 PM

You could make the opacity setting as a slider, like this testcase.
