Hi Phil,
<< nit pick : you spelled luminance wrong here : <<int actualLuminaceDifference Corrected << Some of the variable naming is confusing me. << So until I get clarity on the intent here I can't verify the correctness of the logic that follows although I understand your intent as being to make the highlight lighter so long as it is already lighter than the background and you don't have to exceed max luminance to do it, and if that won't work make the highlight darker instead. And so forth for the other cases. Yes, this is exactly what I am doing. I understand your point about naming. Once I have defined what is highlight and what is background, I should just use these for naming instead of menubar and menuitem. I have corrected the naming of variables used. webrev: http://cr.openjdk.java.net/~pbansal/8226964/webrev01/ Regards, Pankaj From: Philip Race Sent: Thursday, August 1, 2019 6:16 AM To: Pankaj Bansal Cc: swing-dev@openjdk.java.net Subject: Re: <Swing Dev> [13] RFR JDK-8226964 [Yaru] - GTK L&F: There is no difference between menu selected and de-selected nit pick : you spelled luminance wrong here : int actualLuminaceDifference Some of the variable naming is confusing me. Color highlightColor = style.getGTKColor( + GTKEngine.WidgetType.MENU_ITEM.ordinal(), ok so Highlight comes from MENU_ITEM and background comes from MENU_BAR : + Color backgroundColor = style.getGTKColor( + GTKEngine.WidgetType.MENU_BAR.ordinal(), but then we assign menubar luminance from highlight which was got from menu item and menu item luminance from background which was got from menu bar double menubarLuminance = getY(highlightColor.getRed(), + highlightColor.getGreen(), highlightColor.getBlue()); + double menuitemLuminance = getY(backgroundColor.getRed(), + backgroundColor.getGreen(), backgroundColor.getBlue()); Can you explain this ? Or is it wrong ? I get further confused when I read .. + // when the highlight has more luminance and it's luminance + // can be increased further by minLuminanceDifference + if ((menubarLuminance < menuitemLuminance) && .. so menuItemLuminance is greater implying it is the highlight but we derived it from the background.

Bug: https://bugs.openjdk.java.net/browse/JDK-8226964 webrev HYPERLINK "http://cr.openjdk.java.net/%7Epbansal/8226964/webrev00/"http://cr.openjdk.java.net/~pbansal/8226964/webrev00/ Issue: The menu is not getting highlighted on being selected. The issue is only reproducible on Yaru theme as the menu highlight color used by java is very similar to the background color of menubar. So the highlight is not properly visible due to poor contrast. Fix: The fix checks that if the background menubar color and highlight color are very close, make the highlight more darker or lighter, so that it is clearly visible. Testing: The fix can be verified by running SwingSet2. I have verified this on Ubuntu 16.04, 18.04, 19.04 and OEL 7.5. Regards, Pankaj Bansal
