I have the Qalculate plasmoid in my panel to have it easily accessible and have assigned a shortcut to quickly open it. When triggering the plasmoid by shortcut, however, the input field is not automatically focussed requiring the mouse to click it…

How I can decrease height of plasmoid?
It eats much of space in vertical-aligned panel! See the screenshot: http://wstaw.org/m/2011/03/17/qalculate_plasmoid.png

It uses only one line for display result and one line for input, how I can remove wasted space from it?

The latest qalculate on Debian Sid (unstable) breaks the applet. The applet apparently tests for its presence on startup and the new version is "not found."

Quick fix? New version?

BTW: The runner version still works OK.

maybe you can try to rebuild it against the new lib?

Download link is now fixed. Sorry for the late answer.

BTW, the applet is now included in KDE SC 4.4 (in kdeplasma-addons).

Another feature request:
It would be nice if there was an option to automatically clear the input line of previous inputs.

2 ideas:
- When setting focus to the input-field after activating via keyboard-shortcut or click an the widget area, you could select all the input. This way by typing a new formula, the old text will automatically be overwritten

- If used in a panel, you could add an option "erase input line, when widged closed/hidden"

I'm using widget version 0.7.2 with KDE 4.3.1.

Nice idea! I'll implement this when I have time.

I love the feature of sci-calculators/qalculate-kde, printing how Qalculate is interpreting my input.
Example:
I enter "5 + 3 * 16 ^ 2 + 7 / 9"
And Qalculate prints "5 + (3 * (16 ^ 2)) + (7 /9)" beneath

I would imagine that there is somewhere a function in sci-libs/libqalculate around returning this string. So implementing should not be a big problem.
Maybe an extra option in settings dialog "[ ] show interpreted input".

BTW: The package names are from gentoo portage.

I'll have a look at the API and see if this can be easily implemented. Thanks for the suggestion.

Hi,

I cannot execute the above term as I cannot type ^.
I tried it with a fresh user using DE Layout. ^ is working in konsole and any other KDE programs.

I switched to US Layout and it works.

Thanks!

I cannot reproduce this. I tried also with a German keyboard and it works fine here.

What happens if you press the '^' key twice? Will the '^' sign appear? If that's the case, you might have to change some locale-related settings.

Hmm.
On KDE 4.3.73 it does not work.
On KDE 4.3.2 it works.

So, I guess it is ok, if it just works on stable branch...

Thank you

First of all, great plasmoid. Very useful.

It would be nice if the textbox got focus if you click anywhere on the widget. I implemented this for myself (for fun) a while ago, but I'm sure it's no problem for you to do it.

(1. I'm not sure I did it the right way. 2. I don't have access to that machine at the moment. Sorry about that, would be fun to send a patch otherwise. :P).

I second the request. Also when opened via keyboard shortcut the input line should get focus, right now you need to click on it after it's opened

Feature added in v0.7.1. It can be disabled in the plasmoid settings, if wanted.

Works in "normal life", thx!

But the focus is not set to the input field (after activating via shortcut), if you used the plasmoid "show the desktop" to minimize all application windows. No idea, why!

Yes, I am aware of this but unfortunately I don't know how to solve it.

I agree with you that this would be a nice feature. At the moment I am quite busy, but I will implement it as soon as I get the chance. Thanks for the feedback!

It looks like you are missing some development packages. Try installing kdelibs5-dev with: sudo apt-get install kdelibs5-dev. Then run cmake again.

Thanks! I added the library, and the applet compiled like a charm. :-)

Now if I can only figure out how RPN works on Qalculate. :-|

RPN is not exactly intuitive at the moment. To use it, you have to enter an expression like this: "123 98 +" ant then press ENTER.

If you have some ideas how to improve it, let me know :)
