How to bind a text domain to a local folder for gettext under GTK3

阅读更多关于 How to bind a text domain to a local folder for gettext under GTK3

With gettext you can either use the default system-wide locale directory, or specify one yourself using bindtextdomain . This is useful when running a program directly from source when the compiled .mo translation files are not available in the system's default location. In Python you would do this: import gettext from gettext import gettext as _ gettext.bindtextdomain('nautilus-image-manipulator', '/path/to/mo/folder') gettext.textdomain('nautilus-image-manipulator') where /path/to/mo/folder contains the familiar fr/LC_MESSAGES/nautilus-image-manipulator.mo structure. Calls like this: print _

It says Unresolved refrence: 'Gtk' when I hover over Gtk in my import statement, and of course none of the auto-completion works. This is my code: #!/usr/bin/env python3 from gi.repository import Gtk win = Gtk
