如何获取 QlistWidget 中存在的文件路径

Question

我有一个代码在 QlistWidget 中显示项目（文件），用户点击项目，系统会显示其内容。

示例：

• C:\Users\test\Desktop\New Microsoft Word Document.docx ==> 第 0 行
• C:\Users\test\Desktop\test_arabic.docx ==> 第 1 行

当尝试打印结果时，系统显示正确的行号但路径错误，无论您接下来选择什么，它都会显示第一个选择的文件路径

代码：

  def FileListSelected(self):             # Function to select the desired file from the list in the left pane
        ListIterator=range(self.listWidgetPDFlist.count() -1)

        for index in ListIterator:
            p = pathlib.Path(self.fullPath)
            print(" FILE SELECTED this is P==>{}".format(p))
            oneDir = os.path.join(*p.parts[:-2])
            print("FILE SELECTED this is oneDir==>{}".format(oneDir))            
            Item= oneDir + "\\" + self.listWidgetPDFlist.selectedItems()[index].text()
            print("FILE SELECTED this is the cuurent Item =={}".format(Item))            

            print("current row = {}".format(self.listWidgetPDFlist.currentRow()))
            self.mouseHover()
            return Item

Answer 1

由于您没有提交完整的代码，我将您的fileListSelected(self) 方法插入到我的示例中。

不知道self.fullPath是什么，所以我将当前目录的路径设置为os.getcwd()。

1. 执行add items
2. Show selected file

试试看：

        self.textEditTotalPDFnumber.setReadOnly(True)

        self.listWidgetPDFlist = QtWidgets.QListWidget()

        self.vlayout = QtWidgets.QVBoxLayout()
        self.vlayout.addWidget(self.listWidgetPDFlist)
