问题描述
我有一个 pyqt4 程序,想实现多语言支持.我有所有的 .qm 文件,但不知道如何使用它们.
I have a pyqt4 program and would like to implement multilingual support. I have all the .qm files, but can't figure out how to use them.
我真的找不到太多关于这方面的文档,而且我尝试的任何东西似乎都不起作用.
I can't really find much documentation on this, and nothing I try seems to work right.
推荐答案
有大量关于这个主题的文档,可以在明显的地方找到:
There's tons of documentation on this subject, which can be found in the obvious places:
下面是一个简单的演示脚本(使用-h
运行):
Below is a simple demo script (run with -h
for usage):
from PyQt4 import QtCore, QtGui
class Window(QtGui.QWidget):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
message = self.tr('Hello World')
label = QtGui.QLabel('<center><b>%s</b><center>' % message, self)
buttonbox = QtGui.QDialogButtonBox(self)
buttonbox.addButton(QtGui.QDialogButtonBox.Yes)
buttonbox.addButton(QtGui.QDialogButtonBox.No)
buttonbox.addButton(QtGui.QDialogButtonBox.Cancel)
layout = QtGui.QVBoxLayout(self)
layout.addWidget(label)
layout.addWidget(buttonbox)
if __name__ == '__main__':
import sys, os, getopt
options, args = getopt.getopt(sys.argv[1:], 'hl:')
options = dict(options)
if '-h' in options:
print("""
Usage: %s [opts] [path/to/other.qm]
Options:
-h display this help and exit
-l [LOC] specify locale (e.g. fr, de, es, etc)
""" % os.path.basename(__file__))
sys.exit(2)
app = QtGui.QApplication(sys.argv)
translator = QtCore.QTranslator(app)
if '-l' in options:
locale = options['-l']
else:
locale = QtCore.QLocale.system().name()
# translator for built-in qt strings
translator.load('qt_%s' % locale,
QtCore.QLibraryInfo.location(
QtCore.QLibraryInfo.TranslationsPath))
app.installTranslator(translator)
if args:
# translator for app-specific strings
translator = QtCore.QTranslator(app)
translator.load(args[0])
app.installTranslator(translator)
window = Window()
window.setGeometry(500, 300, 200, 60)
window.show()
sys.exit(app.exec_())
