Is there a recommended strategy to deal with Qt5 software in TDE?
This is somewhat like dealing with GTK software.
On my systems, Qt5 programs look awful in TDE, mostly really tiny fonts and ignoring themes. Qt5 tools look normal when I use KDE.
I am aware of qt5ct. That tool provides some sanity with Qt5 tools in TDE, but usage needs to be limited to TDE. Otherwise qt5ct introduces its own frustrations in KDE.
Thanks.
I found a port of the Plastik style to Qt5 and Qt6 a while back. Seems like as good a time as any to share the love.

My same reply as previous -- Qt5 apps are not necessarily KDE. Two such tools I use are Goldendict and QuiteRss. They are not KDE tools and have no KDE library dependencies.

Somewhere ... somewhere ... there are at least 3 or 4 separate threads that discuss this issue, or what I believe to be the issue that you're discussing.
A few of us have, in the past, recommended adding the gist of this information to our help pages, as it begins to seem like there is an echo in here.
The rest of this post is copied from earlier posts, and consolidated here.

P.S. how to
For these instructions, I will assume that you are running Debian or Devuan or a similar OS. If it is not a deb system, then, you will need to adjust accordingly. But from what I have heard from others, these steps ought to work. It may be that some things have changed or been upgraded, but aptitude, for instance, will tell you that.
#1, using apt-get, aptitude, synaptic, or however you install packages, you want to get these:
qt5ct qt5-assistant qca-qt5-2-utils qdbus-qt5 qdoc-qt5 qps qt5-default* qt5-flatpak-platformtheme qt5-gtk-platformtheme qt5-image-formats-plugins qt5-qmake qt5-qmake-bin qt5-qmltooling-plugins qt5-style-plugins
You may want to check out these threads: "how to force TDE colors in non-TDE apps?" and especially the sequel: "how to force TDE colors in non-TDE apps? SOLVED" 2021-01-18 or thereabouts (an exchange mostly between E.Liddell and myself).
But here is the gist of it: https://askubuntu.com/questions/706528/qt-apps-stopped-inheriting-gtk-themes... https://web.archive.org/web/20201111174652/https://askubuntu.com/questions/7... wherein are unlocked the mysteries of qt5ct in a single line.
*NOTE that other pages gave information which was either contradictory or at least unclear, leaving me frustrated and unable to figure out where in /home/<USER>/.profile to insert the line for qt. So for other Trinity users out there who may want to use the look of their TDE and color outside the lines when using non-TDE apps, this is what actually worked for me.*
After installing qt5ct and whatever other packages (more for developers), run this command: sudo sh -c "echo 'export QT_QPA_PLATFORMTHEME=gtk2' >> /etc/environment"
Open qt5ct and choose according to personal preferences, then reboot. The user will now have TDE colors and themes in non-TDE applications. It will also run gtk2 and gtk3, and lots of other good stuff. It seems like it will work for other desktops, as well, as others say.
For most users, this will probably take care of their needs.
It sounds like this is what you're looking for. E.Liddell pointed me in this direction, and the rest I nicked from the webpage mentioned above.
I hope this helps!

Thank you Bill.
Looks like I was already on the correct path with qt5ct.
With respect to exporting QT_QPA_PLATFORMTHEME, I placed my script in $TDEHOME/env. Early in my tinkering with qt5ct I discovered a global approach (system-wide or user bash startup files) causes weeping and gnashing of teeth when I used Qt5 apps in KDE.
These theme conflicts always have been an issue with GTK/Qt and in later years Qt4/Qt5. And at least for me, the TDE gtk theme engines are broken.

I forgot to say, there is also a package, lxappearance, which obviously is tailored more to the lxde desktop, but it can be use to make some changes in themes and appearance.

I may be misunderstanding your question or merely stating the obvious, but when installing the great wad of stuff necessary to run KDE-5 apps, you may have installed or easily can install the KDE-5 configuration application. Here, I configure the KDE-5 applications with that and the TDE applications using the TDE configurator.

Perhaps I should have written standalone Qt5 tools -- which are not KDE. For example, two such tools I use are Goldendict and QuiteRss. They are not KDE tools and have no KDE library dependencies.
