many thanks duncan,  :-) , sorry, but I intend KDE application as one
of the three branch in whitch kde splitted itself as KDE-framework and
plasma.
so with kf5-config --version I get version of kde-framework and with
plasmashell --version I get the version of plasma which is the command
to get the version of KDE-applications???
By querying --version of an application, e.g.
kate --version dolphin --version ark --version

hi kevin, it doesn't work ... :-)  :-)  :-)

googling
in august 2015 kde applications was:
KDE Ships KDE Applications 15.08.0
and I cannot see any bigger or similar to this

pla@suseST-pla:~> kate --version
Qt: 4.8.6
KDE Development Platform: 4.14.17
Kate: 3.14.17
pla@suseST-pla:~> dolphin --version
dolphin 15.12.2
pla@suseST-pla:~> ark --version
Qt: 4.8.6
KDE Development Platform: 4.14.17
Ark: 2.19
pla@suseST-pla:~> konsole --version
Qt: 4.8.6
KDE Development Platform: 4.14.17
Konsole: 2.14.2
pla@suseST-pla:~> systemsettings5 --version
systemsettings 5.5.4
pla@suseST-pla:~>
Those Qt 4.x, kde 4.14.x, versions, are still the kde4 (4.14.17, here
based on qt 4.8.6) versions.

It is worth noting, however, that with kde/frameworks5 and kde apps 15.x,
applications are switching from the older qt/kde4 versions to the new qt/
kde5 versions individually, one at a time as their maintainers consider
them ready.  This is quite unlike the kde3 -> kde4 switch, as kde4 wasn't
as modularized as kde/frameworks5 is, and everything that at the time
shipped with kde core had to sync on the same kde core version, so the
choice was either use all the new versions even when some aren't ready,
or use all the old versions even tho upstream isn't updating most of them
any further and they're effectively unsupported.

So kde apps 15.08 still shipped with a lot of kde4-based apps, and even
kde apps 15.12 ships with a significant number, tho a few more apps have
switched to their frameworks5 versions in 15.12, compared to 15.8.

FWIW, I'm running kde apps 15.12.1 here, tho I only have select apps
installed and kate isn't one of them, tho kwrite is.

$ kwrite --version
kwrite 15.12.1

$ dolphin --version
dolphin 15.12.1

$ ark --version
ark 15.12.1

$ konsole --version (as posted earlier)
Qt: 5.5.1
KDE Frameworks: 5.19.0
Konsole: 15.12.1

$ systemsettings5 --version
5.5.4


All of those but systemsettings5 are part of kde apps, with
systemsettings5 being part of plasma, thus the differing version there.
And all reported --version outputs correspond to the package versions I
have installed, here on gentoo:

kde-apps/kwrite-15.12.1
kde-apps/dolphin-15.12.1
kde-apps/ark-15.12.1
kde-apps/konsole-15.12.1

kde-plasma/systemsettings-5.5.4

And at least in kde apps 15.12.1, all of those are qt/kde/frameworks5
based.

Here's a few examples of 15.12.1 packages still based on qt/kde4, however
(with the list of deps on kdelibs package-manager queried first, since
all kde4 apps dep on it, while kde5 doesn't have a kdelibs package, it's
broken into various individual frameworks packages, then a few of them
picked as examples to post here):

$ okular --version
Qt: 4.8.7
KDE Development Platform: 4.14.17
Okular: 0.24.0

But that's from the kde-apps/okular-15.12.1 package.

Similarly, a lot of the old kde-games packages are still kde4 based:

$ palapeli --version
Qt: 4.8.7
KDE Development Platform: 4.14.17
Palapeli: 2.0

But its package is kde-apps/palapeli-15.12.1

And:

$ kreversi --version
Qt: 4.8.7
KDE Development Platform: 4.14.17
KReversi: 2.0

But its package is kde-apps/kreversi-15.12.1


So as you see, apps that have been kde/frameworks5 ported show the
15.12.1 version that corresponds to the kde apps package they come from,
while apps that are still kde4 based still report kde 4.14.17 (the kdelibs
version) and whatever package-specific (or perhaps kdegames module
specific) version number, whether that's the 0.24.0 of okular, or the 2.0
of palapeli and kreversi.

If your distro is still running kde apps 15.08, quite a few more of those
apps will be kde4 based, and while I don't know for sure if the specific
ones you listed are, there's a pretty good chance that in 15.08 they are,
tho by 15.12, as I demonstrated, many of them are kde/frameworks5 based,
tho there's still quite a few kde4 based apps left to port, and some may
never get ported.

(One of the still kde4-based apps I continue to use that I know is in the
"won't be ported" category is superkaramba.  While it was part of the
15.08 releases, it was still kde4 based there, and it's not part of the
15.12 releases.  Fortunately, the old kde4-based kde-apps/
superkaramba-15.08.3 still works for now, but eventually, I'll either
have to rewrite my superkaramba theme to qtquick, thereby porting it to
plasma5 directly, or switch to gkrellm or konqy and rewrite to their
widget types, since superkaramba is now officially a dead end, and it's
only a matter of time now until superkaramba either breaks, or most of
the rest of my kdelibs4 based apps have been frameworks5 ported, and the
rest abandoned and left for dead, and either kdelibs4 itself is abandoned
and breaks, or I've so little stuff left using it that I want it off the
system so I don't have to worry about it as a dep any longer.)

The situation becomes even more confusing with the current 5.20.0 release and the 15.12.3 applications. Some of these will still build for only Qt-4 while others will build for either Qt-4 or Qt-5 (with KF5) some depending on whether Qt-4 or Qt-5 is available and a very few having to be told to use KF5 even if they can't find Qt-4 because I removed it from the PATH as per BLFS instructions.

So, I wouldn't really say that the version of the application is the important thing to know. What is important to know is whether you are using a KDE-4 or KF5 application -- presuming that unless something went wrong that you should be using the latest installed application for the respective KDE-4 or KF5 systems.

This does leave a user with a problem. If you have both KDE-4 and KF5 versions of an application installed, there is no way to tell them apart. The desktop files do not have different names for the applications (e.g. Konquror-4 & Konqueror-KF5) and the desktop files do not have paths in the "Exec" statement so you always get the same One dependent on the PATH.

So, I think that I will have to install the KDE-4 versions of the missing KF5 applications in the KF5 directory and remove the KDE-4 directory from the path. Special cases will have to be made for Kalarm which has a TimeZone problem with KF5 and Konqueror which I what to have both versions of available.
