Scrap that as it gives the webview content transparency as well. You'll need to subclass window and set it such that the background is not drawn. I.e.:

- (id)initWithContentRect:(NSRect)contentRect styleMask:(unsigned int)aStyle backing:(NSBackingStoreType)bufferingType defer:(BOOL)flag { #pragma unused(aStyle) if ( ( self = [super initWithContentRect:contentRect styleMask:NSBorderlessWindowMask backing:bufferingType defer:flag] ) ) { [self setBackgroundColor:[NSColor clearColor]]; [self setAlphaValue:0.0]; [self setOpaque:NO]; [self setHasShadow:NO]; return self; } return nil; }

Did you set the window's transparency using setAlphaValue? That should be all you need.

OK, so Safari in 10.3.9 allows a transparent window (see the Debug menu), which works nicely when you embed CSS formatting for background transparency in your HTML:
    <STYLE type=\"text/css\">
    BODY { background-color: transparent }
    </STYLE>
I have an app with a transparent window, but all WebViews have an opaque white background by default. Anyone know a way to force the WebViews to have a transparent background so that full transparency can be realized?? I assume that if Safari Can do it, any WebView should be able to support it as well.
Thanks,
Craig
