[SOLVED] How to uninstall QT 5 Assistant, QT 5 Designer, QT 5 Linguist?

How to uninstall QT 5 Assistant, QT 5 Designer, QT 5 Linguist in the category Development as I don't need them?
For example, the desktop files says > Exec=/usr/bin/qtchooser -run-tool=designer -qt=qt5
Do I uninstall qtchooser? Would it trouble other apps?

Try

apt-get purge -s qtchooser

in your terminal. This simulation, which doesn't need sudo, will show you what else will potentially be removed. After trying the code on my system, I certainly wouldn't uninstall qtchooser.

Thanks!
Is it enough to delete the relevant desktop files in /usr/share/applications to get rid of the Development category in the menu?
EDIT: I did just that and that category is gone.

What version of Kubuntu are you on?

Never mind, these are present in 18.04 but not in 16.04.

By the way, the next time the applications update, the .desktop files will be back AFAICT!

I have 18.04 dev.
I'd like to find a way to get rid of all these unwanted (for me) apps. I don't want Kmail (don't use this kind of mail for decades) and any related apps. Uninstalled Kmail, but not the others yet. I was with Kubuntu on and off, so never learned how to use KDE well. Would be asking (silly) questions.

You can remove menu entries with no consequence. Removing some applications that may be fundamental to operating the distro are not good.

A clean install of Kubuntu, while good, means uninstalling or deactivating certain high level applications such as Kmail, Akonadi, indexing and other bad news. What remains is clean and fast!

1) I haven't used an installed email client app for ages. I use web email.
2) While, some apps come in the meta package as included in the DE, some of them such as Kmail should be allowed to be uninstalled by user. Kmail, for example, is doesn't have anything to do with KDE working correctly.

... Kmail, for example, is doesn't have anything to do with KDE working correctly.

At least on 16.04,

$ apt purge -s kmail
NOTE: This is only a simulation!
     apt-get needs root privileges for real execution.
     Keep also in mind that locking is deactivated,
     so don't depend on the relevance to the real current situation!

Purg kmail [4:16.04.3-0ubuntu2~ubuntu16.04~ppa63]

So getting rid of kmail seems quite possible and doesn't appear to bring down the house. I'm going to leave it there even though I don't use it.
