How to change the cursor to a watch in GTK for C?
c, gtk, mouse-cursor
Solution
Use `gdk_set_cursor()`
(https://developer.gnome.org/gdk3/stable/gdk3-Windows.html#gdk-window-set-cursor)
on a GdkCursor created by `gdk_cursor_new()`
(https://developer.gnome.org/gdk3/stable/gdk3-Cursors.html)
Problem
I'm using the C-style GTK functions in C++ and I can't figure out how to set the cursor for the main window.
