Gtk stopped working for me on MacOS sometime this semester (I am teaching a music signal processing course using Julia with >60 students). Here is a MWE of code that worked a month or so ago and now does not work on MacOS 13.6.6 or 14.4.1 (it is likely that I’ve done security updates for both versions during the term):
using Gtk
win = GtkWindow("My First Gtk.jl Program", 400, 200)
b = GtkButton("Click Me")
push!(win,b)
function on_button_clicked(w)
println("The button has been clicked")
end
signal_connect(on_button_clicked, b, "clicked")
signal_connect(win, "key-press-event") do widget, event
println("You pressed key ", event.keyval)
end
showall(win)
I am using Julia 1.10.2 and Gtk v1.3.0 in both cases.
The error message is: (<unknown>:18639): Gtk-WARNING **: 21:31:19.255: drawing failure for widget 'GtkButton': the surface type is not appropriate for the operation
I reported the issue Gtk not working on MacOS Sonoma 14.4 or 14.4.1 · Issue #698 · JuliaGraphics/Gtk.jl · GitHub but I wanted to see if anyone in the broader Julia community is able to get Gtk to work on any version of MacOS. This has been a big headache for my students (and me).
