Objective-C, NSPopMenuButton & NSMenu Color

Question

I have an NSPopMenuButton which is connected to an NSMenu in the standard way. I tried sub-classing both in an attempt to change the background color of the menu itself. I'm clearly not doing something correctly, so any advice would be helpful.

Tried (NSPopUpButton) customPopUpButton.m:

- (void)drawRect:(NSRect)dirtyRect {
    [super drawRect:dirtyRect];

    // Drawing code here.
    [[NSColor grayColor] set];
    NSRectFill(dirtyRect);

}

Which gave me: I'd actually rather it be like:

I tried creating another class to override NSPopUpButtonCell as suggested by another answer, but I must not know how to implement it correctly as it seems to have no effect other than what the code above does.

- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView {

    [[NSColor grayColor] set];
    NSRectFill(cellFrame);

    [super drawInteriorWithFrame:cellFrame inView:controlView];

}

Something to note is that my deployment target is macOS 10.11 if that makes any difference.

@Willeke, I tried that actually but I don't know how to properly implement the suggestion in the answer. I added a new sub-class to `NSPopUpButtonCell` and put the method in, but it seems to do nothing that the original code I posted does. — Joe Habadas, Mar 29 '20 at 16:28

Your customized NSPopUpButton drawing is filling the entire drawing area with color. Default title drawing is missing (under the filled color).

Try customizing NSPopUpButtonCell drawInteriorWithFrame:(NSRect)cellFrame inView:(NSView *)controlView.

Can you please show an example of how to implement this? I tried and nothing happens other than what already is taking place. – Joe Habadas Mar 29 '20 at 16:29

@Joe Habadas,When you used customized nspopupbuttoncell,did you remove customization done for nspopupbutton? – anonymous Mar 30 '20 at 08:11
I finally got the NSPopUpButtonCell to show the color correctly with the text after removing the customization in NSPopUpButton, but the NSPopUpButtonCell did not colorize the NSMenu items, so I guess that is something else I need to subclass? In the meantime I selected "Dark Aqua" for the View's Appearance, which worked. I would like to do that programmatically though if possible. – Joe Habadas Apr 03 '20 at 05:29
@JoeHabadas, You can set the appearance programmatically; [someView setAppearance:[NSAppearance appearanceNamed:NSAppearanceNameDarkAqua]]; – anonymous Apr 03 '20 at 12:29
