Windows 11 round corners and non native title bar?

[Cap10]

Is it possible to get the windows 11 round corners on a juce standalone application window and not use the native title bar?
setUsingNativeTitleBar(false);

Found the solution in this forum post:

Custom window border with no gaps?

I think the previous post from LightAndSoundLTD is correct; you’ll need to set the window attribute for the Desktop Window Manager. You don’t need to rewrite any part of JUCE, but you will need to add some Windows-specific code to your app to set the DWMWA_WINDOW_CORNER_PREFERENCE window attribute. Docs here: https://learn.microsoft.com/en-us/windows/win32/api/dwmapi/ne-dwmapi-dwm_window_corner_preference Setting that attribute gave me a window with rounded corners and a drop shadow. [image] …

Here is an up-to-date version of that solution:

In your mainWindow component, add this at the top:

#if JUCE_WINDOWS || JUCE_MAC
	extern void setRoundedCorners ( void*, bool );
#endif

And in your mainWindow component then add this:

#if JUCE_WINDOWS || JUCE_MAC
	void parentHierarchyChanged () override
	{
		juce::DocumentWindow::parentHierarchyChanged ();

		if ( auto peer = getPeer () )
			setRoundedCorners ( peer->getNativeHandle (), ! isUsingNativeTitleBar () );
	}
#endif
