Description: Add a Dark Theme

Hello, I was looking for a Duplicate finder on Windows 10 64-bit and I stumbled upon dupeGuru and Czkawka. I chose Czkawka because it is dark by default and I prefer programs with Dark themes.

Are the developers considering a Dark theme for dupeGuru? Personally I would find this feature very relevant. I use a lot of FLOSS software on GNU/Linux, Windows & Android and most developers have released their app with a choice of Light or Dark themes.

Note: I am not talking about design

I think that Czkawka has a more refined user interface: custom fonts, rounded buttons, window actions imitating MacOS' design, ...

But this is not related to my request. I can totally use a program that may not have a "modern look", the same dupeGuru but dark would be very fine.

+++ Thank you to the developers 😉🧡

Thanks for making the efforts to develop a program for the Internet, and especially in GPLv3 🧡

DupeGuru uses the Qt framework. You can use dark themes all you want. I'd recommend checking out Kvantum for example, otherwise you can use qt5ct.

Here is how it look in Arch Linux with Kvantum's "KvMojave" theme for example:

Thanks for the advice @glubsy 🙂

But I am using Windows 10, not GNU/Linux. Also, it looks complicated, I was thinking more of a checkbox (like in Handbrake or another setting a non-knowledgeable user could toggle easily.

My request is to ask whether the developers have thought of a simple setting to toggle Light/Dark themes. If not and/or if you think that my request is irrelevant there is no problem 🙂

I would love that too honestly. It'd be great!

Played around with some things on this, I found a way to add in a darker style to the UI that is not 100% perfect but was fairly fast, I will add it in for the next release, it probably will need some additional work, so I would consider it beta quality or such.

Added dark style for windows in f6a0c0c, closing.

@arsenetar got an error when trying to open the Options dialog:

@glubsy Yup, I see what happened there, I missed a few platform guards since the option is only there in windows, should be fixed now.

@arsenetar Works fine now!
