PySide2 QFileDialog失败

Question

为什么这样做：

# user select report style file
options = QFileDialog.Options()
parent = None
filters = "All Files (*);;Report Style Config (*style*.ps1)"
title = "Style Config Save File"
open_at = getcwd()
self.styleConfigFile, _ = \
    QFileDialog.getOpenFileName(parent, QObject.tr(title),
                                QObject.tr(open_at),
                                QObject.tr(filters),
                                options = options)

失败...

我已经按照在线指南重新编写了此代码3次，每次都会遇到相同的失败。我在做什么错？

Answer 1

答案很简单，我需要从中更改代码：

self.styleConfigFile, _ = \
    QFileDialog.getOpenFileName(parent, QObject.tr(title),
                                QObject.tr(open_at),
                                QObject.tr(filters),
                                options = options)

至此：

self.styleConfigFile = \
    QFileDialog.getOpenFileName(parent, title,
                                open_at,
                                filters,
                                options = options)[0]
