A calculator plasma widget which uses the Qalculate! library to provide lots of features like unit calculation or currency conversion.
In order to install this widget the Qalculate! library is required. Get it at http://qalculate.github.io/.
can you put a link in the ui to get quickly acces to the GTK-UI. ?
e.g. clik on the picture logo will launch the app!
I'm not sure I fully understand your request. Do you want a button on your task bar which launches the app or do you want a button (or any other clickable object) inside the widget?
a button (or any other clickable object) inside the widget !
Can you check if this meets your requirements?
The plasmoid doesn't give me results, only "Error" as result. I don't have errors in the compilation and qalculate-gtk works fine. I search it, but I can't find anything. Could you give any tip?
It's difficult to guess what the problem might be. Are there any errors when installing the plugin?
Maybe you could open an issue on Github with some more details like which distribution, compiler and KDE version you are using.
Nevermind. My fault. Forgot to read the bit where you said that libqalculate 2.5 or higher is required. Thanks!!
That part about the requirement of libqalculate v2.5 only refers to the new feature of using the two's complement representation for negative numbers. Apart from that the latest version should hopefully work with all (recent) versions of libqalculate (including v2.2).
The error message you receive looks like an ABI incompatibility between libqalculate and the plugin.
If possible please open a bug report on the Github page, which is much better suited to discuss such issues.
Could you give any tip or so?
This looks like a version conflict. When you use libqalculate 2.0.0 it should not try to link stopPrintControl().
How did you install the libqalculate? Manually or with a package manager? What does the output of the cmake command say.
~/setups/pkg/qalculate-0.4.0/build$ su -c "make install"
There was no bugs in your code. I successfully could built qalculate after some cleaning in my own library instlltion. Thank you for you suport!
Usually whenever libqalculate was upgraded, all that I had to do is to recompile the plasmoid. However, after I upgraded libqalculate to 2.0 and recompiling the plasmoid, I was unable to start plasmashell; there was a "malloc(): memory corruption" message even. I was able to get plasmashell starting again after removing the plasmoid.
The moral of the story is, that plasmoid 0.3x and libqalculate 2.0 do not seem to like each other.
I uploaded a new experimental version to github which should support libqalculate v2.0.0 much better.
Thank you! I just used qalculate 0.4 and it works like a charm!
Are you sure this issue is related to the plasmoid? I have upgraded two different machines to libqalculate 2.0 and both are working fine.
You can use "plasmoidviewer --applet org.kde.plasma.qalculate" to run it separately from KDE and see some debug messages in the konsole.
+ as if there are not 6 gazillion caculators already. usability is not very high in this thing.
