How can I set the icon in the TitleBar on GTK/Skia on Windows?

[HakanL]

I'm running my Uno 5 application on Windows, using Skia/GTK. How can I change the default icon of the application? I'm not sure if it's Windows-specific as I'm running full-screen on Linux so it's not an issue there. This is the icon I'd like to change:

I tried to set ExtendViewIntoTitleBar, but it didn't seem to make a difference, or I'm not sure how to use it or what to expect.

This icon is coming from the imported Package.appxmanifest file from the Windows file. It's set through:

uno/src/Uno.UI.Runtime.Skia.Gtk/UI/Controls/UnoGtkWindow.cs

Line 98 in 6041207

internal void UpdateWindowPropertiesFromPackage()

When this line is set in the template.

Hmm, that makes sense, but I have those set, however it's set like this in my GTK head:

<ItemGroup Condition="exists('..\DMXCore100.Windows')">
   <EmbeddedResource Include="..\DMXCore100.Windows\Package.appxmanifest" LogicalName="Package.appxmanifest" />
</ItemGroup>

and then in the linked appxmanifest I have this:

  <Properties>
	<DisplayName>DMX Core 100</DisplayName>
	<PublisherDisplayName>DMX Core</PublisherDisplayName>
	<Logo>Images\StoreLogo.png</Logo>
  </Properties>

And that image exists (under the Windows head project), but it's not the one that is displayed (screenshot above). I tried to also create an Images/StoreLogo.png file under the GTK head, still didn't work. What am I missing?

Take a look at the logs for the app, it may indicate what's happening. Otherwise, something else may not be working and we'll need to open an issue with a repro.

Yup: Unable to find icon file [C:\Projects\DMXCore\100\Software\DMXCore100.Skia.Gtk\bin\Debug\net8.0\Images\StoreLogo.png] specified in the Package.appxmanifest file.. So I added the logo to the GTK head, but I forgot to set the build action to Content. After that it worked, thanks for pointing me in the right direction!
