 x^5=100: ^ does not work

 by Finswimmer on: Oct 29 2009

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.

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.

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

 input interpretation

 by px79 on: Nov 8 2009
Score 50%

I love the feature of sci-calculators/qalculate-kde, printing how Qalculate is interpreting my input.
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.

 clear input line

 by px79 on: Nov 8 2009
Score 50%

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.

 Latest Qalculate Breaks Applet

 by dovidhalevi on: Feb 7 2010
Score 50%

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.

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

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

 Decrease height of plasmoid

 by Murz on: Mar 17 2011
Score 50%

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?

 Auto focus input field when triggering by shortcut

 by KjaB on: Dec 8 2011
Score 50%

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 do you like Plasma 5?
 The best KDE Desktop ever.
 Definitely a nice improvement.
 Not decided yet. Haven't tried it yet.
 I do not like some of the changes.
 KDE is taking the wrong way.
 I am still sticking with KDE 3.5.
 I have no opinion, but wanted to vote anyway.
