如何在QLabels中显示国际脚本?

问题描述

我想在QLabel中显示印度语，阿拉伯语和希伯来语脚本，并指定字体类型.当我尝试将UTF-8编码的字符串传递到QLabel时，脚本无法正确呈现.

I would like to display Indic, Arabic and Hebrew scripts in a QLabel, specifying the font type. When I try to pass a UTF-8 encoded string into a QLabel, the script is not rendered properly.

在QLabel中显示国际(非字母)脚本的正确方法是什么?

What is the correct way to display international (non-alphabetic) scripts in a QLabel?

推荐答案

将QLabel的文本设置为unicode字符串(python2中为unicode，python3中为str)应该可以正常工作.

Setting the text of a QLabel to a unicode string (unicode in python2, str in python3) should work fine.

在python2中，您可以使用QString.fromUtf8将utf8编码的str转换为unicode QString，或将.decode('utf-8')转换为python unicode.

In python2 you can use QString.fromUtf8 to convert a utf8-encoded str to an unicode QString, or .decode('utf-8') to a python unicode.

在python3上的PyQt4中，QString消失了，因为现在str已经是unicode了，所以只需使用它即可.

In PyQt4 on python3 QString is gone as now str is already unicode, so just use that.

例如:

    s = "اردو"
    d = s.decode('utf-8')
    label = QtGui.QLabel(d)
    font = QtGui.QFont("Sheherazade", 40)
    label.setFont(font)
