Dark Theme

[koosha72]

Hey, I wondered if there is dark theme for this project. I checked the codeproject article and there wasn't any information about theming.

[npolyak]

Hey, so far there is none. I am working on it. Hopefully within 2 weeks - 1 month, I'll release it.

[koosha72]

Thanks. I've worked with your project and it's great. It doesn't seem to have any problems.

Just as I wanted to clone this git I noticed there seemed to be a problem with NP.NLogAdapter SubModule. The git cannot be cloned.

Thanks for your great work.

Hey Nick, ...didn't realize you are same Nick as from ITG!! ... worked with you for a bit on TBlack ... :)

Guess what ...Kostya (Konstantin Vints is also working with me ...) ... on a dark theme! .. we are able to style some stuff ... but other things are making us scratch our heads (we not only want to change skin brushes, but also padding, compass etc...)

here is my personal email - maybe (kostya you and me) and have a quick chat - and we can help you come up with different themes ...

Kerrigan - kerrigan_burgess@hotmail.com ... Kostya - kostya.vints@gmail.com

btw: koosha ... i had the same problem with the sub-modules - git clone (even when do git ...clone recursive ...was not working) ... tried using github downloader ...nothing worked... i actually did get it to work ...

but unfortunately had to go to each submodule directly ...and clone it like git clone https://github.com/npolyak/NP.Concepts.Behaviors.git ... do same for all other submodules

... another thing I noticed was ...when you build demos (like under submodules) ... it fails to reference the project... you just have to import the referenced project again ...and add as dependency in visual studio ...

cheers Kerrigan.

Hey Kerrigan, thanks. Nice to hear from you.

I've been very busy and did not have time to work on the theme and neither on fixing the NLogAdapter. It is coming though. Are you and Kostya still in ITG?

You should never use the demos from the sub-modules - you should load the repository containing them as a separate code tree. Then, hopefully they will work.

If you like my software, please, star the repository and vote for my articles on the codeproject.

Thanks

Nick (formerly from ITG) :)

[npolyak]

OK, I did some changes and it should build now - I fixed some old submodule references. the command git clone https://github.com/npolyak/NP.Avalonia.UniDock.git --recursive works perfectly fine for me. I remember people at ITG making fun of this statement "works perfectly fine on my machine", but really do not see any reason why it should not work for you.

[npolyak]

I'll try to add theming within a couple of weeks.

[npolyak]

And yes, send me the pictures of what you are trying to achieve, I'll try to add more degrees of freedom to my package in order to make it easy.

[TruDan]

Maybe it's better to just make use of the avalonia default theme resources instead of creating your own separate styles for light/dark themes? https://github.com/AvaloniaUI/Avalonia/tree/master/src/Avalonia.Themes.Default/Accents

This also makes it easier for projects using this library to customise the colors to fit their own theme too! :)

[npolyak]

Hey TruDan, I am yet to find a theming package that gives me off the shelf theming capabilities that I like. Unfortunately Avalonia is not an exception in that case :). I like almost everything there except for theming.

[TruDan]

That's fair, the main limitation i'm facing currently when trying to make my own Dark theme is places where a colour is set using LocalValue, meaning i can't override it from a style :( Maybe i'm missing something (quite new to avalonia, but i know WPF well)

like here: (custom window - header bar thing) i want to make it gray when its not active

[npolyak]

Sorry for the big delay. I'll try to work on the themes shortly.

[koosha72]

I looked into it and it doesn't seem to be that hard.

Those LocalValues are colors that are set to hard color code in the theme.

I changed the DockStyles.xaml a bit and it now uses the system color values of Avalonia. So if you set the FluentTheme to light it will be light and if you set it to dark it will be dark. I didn't know much of the system colors of Avalonia so it can get much better than what I did. And there are still some hard coded colors.

here is my DockStyles.xaml
