macOS Dynamically Disable/Enable Zoom?

[Darkroom]

is it possible to disable and enable the zoom title bar button (and attached menu item) dynamically in an IBAction statement?

something like...

-(IBAction)showSheet:(id)sender
{
[NSApp beginSheet:sheet modalForWindow:window modalDelegate:nil didEndSelector:NULL contextInfo:NULL];
//and then disable zoom on "window"
}

guess not...

the reason i ask is because i think it's kinda dumb that when a sheet becomes visible, the toolbar and toobar button in the titlebar becomes disabled, but you can still miniaturize and zoom a window, which i think is both pointless and inconsistent...

also, not being able to quit an application when a sheet is present is kinda ghetto... or at least i can't seem to in my app and don't really know why... especially since i can still Hide, Hide Others and Show All

*sigh*... oh apple... you and your random HIG...
