MacOS Theme [Work in Progress]

(Inspired by @MikeCodesDotNET's earlier draft)

image

This theme is currently based on Avalonia.Themes.Fluent, both as a fallback for any controls not covered yet and as starting point for our (somewhat simplified) style definitions targeting AppKit macOS look.

While we are prioritizing controls for Devolutions Remote Desktop Manager initially, the goal is to create a theme that helps all of the Avalonia community to bring a native look to their macOS apps.

Installation

Install the Devolutions.AvaloniaTheme.MacOS package via NuGet:

Install-Package Devolutions.AvaloniaTheme.MacOS

or .NET

dotnet add package Devolutions.AvaloniaTheme.MacOS

In your App.axaml, replace the existing theme (e.g. <FluentTheme /> or <SimpleTheme />) with the macOS theme:

<Application ...>
  <Application.Styles>
     <DevolutionsMacOsTheme />
  </Application.Styles>
</Application>

Note: Some global Styles will also be loaded by default, you can opt out by setting GlobalStyles to false (<DevolutionsMacOsTheme GlobalStyles="False" />). GlobalStyles are also available as a separate tag <DevolutionsMacOsThemeGlobalStyles /> to cover scenarios where consumers would like to scope them to some control instead of including them globally. This is may be necessary to prevent styles from "bleeding out" in cases where that might be undesirable.

Styled Controls

Most of the images below are screenshots from the SampleApp test and demo pages - feel free to check out the code there for more detailed usage examples.
<h3>AdornerLayer</h3>
✅ <h3>AutoCompleteBox</h3>
<img src="https://github.com/user-attachments/assets/a4e939c0-6516-499f-b3e7-8c68e8be2770" alt="AutoCompleteBox demo" style="width: 460px; max-width: 100%;"> <br /><br /> ➡️ See also EditableComboBox in our custom controls
✅ <h3>Button</h3>
<img src="https://github.com/user-attachments/assets/49093553-a8b6-4cbe-b7a5-7c8f6a8ead3b" alt="Buttons demo" style="width: 300px; max-width: 100%;" />
✅ <h3>CalendarDatePicker</h3> <h4>Calendar</h4> <h4>CalendarItem</h4> <h4>CalendarButton</h4> <h4>CalendarDayButton</h4>
<img alt="CalendarDatePicker" src="https://github.com/user-attachments/assets/27ab5934-2b67-439e-b651-ee96aa173a3e" style="width: 488px; max-width: 100%;" /> <br /> <img alt="CalendarDatePicker" src="https://github.com/user-attachments/assets/86284afe-c84d-4761-9a40-a72146b56db5" style="width: 543px; max-width: 100%;" /> <br /> <img alt="CalendarDatePicker" src="https://github.com/user-attachments/assets/7d65388f-3b8f-4055-ae35-dd71f9047b1d" style="width: 488px; max-width: 100%;" /> <br /> <img alt="CalendarDatePicker" src="https://github.com/user-attachments/assets/07410b9f-79df-43ac-bba5-502216f33f29" style="width: 543px; max-width: 100%;" /> <br /> Note: MinWidth is set to comfortably accommodate short date formats & the corresponding default watermark when HorizontalAlignment is set to anything other than the default (Stretch).<br /><br />If you set SelectedDateFormat="Long" you will have to override MinWidth to the longest expected string length, depending on supported languages. Otherwise the control's width will jump when the date is changed.

This is intentional, since scrolling events will not trigger a 'show' (only moving the pointer directly over the track area will) - so completely hiding would be confusing. <br /><br />Mousing over one of the track areas will make the thumb bar grow wider and darker and the track appears. To suppress this behaviour (e.g. on images) use Classes="MacOS_TransparentTrack"
