I've made an attempt to draw custom NSButtons, but it seems I'm reinventing the wheel here. Is there a way to just replace the default images used for the close, minimize and zoom buttons?
Several apps already do it:
- OSX 10.8's Reminders app (they appear dark grey when the window is not key, vs most appear light grey)
- Tweetbot (All buttons look totally custom)
I can generate the system defaults as such
standardWindowButton:NSWindowCloseButton. But from there the
setImage setter doesn't change the appearance of the buttons.
