I'd add that for completeness, hiding the close button and the window icon (on the left at least in Windows) would be interesting. I don't know though if the last one makes sense for Linux and MacOS

Hiding the window icon is related to #4474.

Since there is Window.ShowDialog, this can be used as MessageBoxes in some cases, and the option for removing all 3 buttons or disabling them would be a nice.

Any news?

Any update on this one?

I also am interested in this for a tool window.

+1, disabling individual window title bar buttons (separately from tool window styling) would be wonderful.

This is easy to implement in Windows with just a couple of P/Invoke calls, but on Mac you have to write and compile new Objective-C++ code. No idea about X11.

Code for Windows: already exists in Avalonia, but in a private method.

Code for OSX: this is how Qt handles the job in Objective-C++

Bump. It's been almost a year since the enhancement tag has been applied.

I feel like this feature should get prioritized, considering it's one of the most basic features any UI framework should have.
You can't even disable the maximize button without preventing users from resizing the window.

Hi @slxdy

If you need priority on any issue please reach out to the team in case you have a support agreement. Otherwise you can request paid support, file a PR or wait until it's done.

Because Avalonia is still OSS, it means things are done when they are done.

Thanks for your understanding 🤗
