如何获取QlistWidget中已存在的文件路径
如何获取QlistWidget中已存在的文件路径
提问于 2018-06-18 18:25:22
我有一个在QlistWidget中显示项目(文件)的代码，用户单击项目，系统就会显示其内容。
示例：
- C:\Users\test\Desktop\New Microsoft Word Document.docx ==> row 0
- C:\Users\test\Desktop\test_arabic.docx ==> row 1
当尝试打印结果时，系统会显示正确的行号，但显示错误的路径，其中无论您选择next，它都会显示第一个选定的文件路径
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回答 1

因为您没有提交完整的代码，所以我将您的fileListSelected(self)方法插入到我的示例中。
我不知道self.fullPath是什么，所以我将当前目录的路径设置为os.getcwd()。
执行add items
Show selected file
的
试试看：
import os
import pathlib
import sys

class Window(QtWidgets.QWidget):
def __init__(self, parent=None):
super(Window, self).__init__(parent)
self.textEditTotalPDFnumber = QtWidgets.QTextEdit('QTextEdit')
self.textEditTotalPDFnumber.setReadOnly(True)
self.listWidgetPDFlist = QtWidgets.QListWidget()
self.vlayout = QtWidgets.QVBoxLayout()
self.vlayout.addWidget(self.listWidgetPDFlist)
self.vlayout.addWidget(self.textEditTotalPDFnumber)
self.btnAddItems = QtWidgets.QPushButton()
self.btnAddItems.setText('add items')
self.vlayout.addWidget(self.btnAddItems)
self.btnAddItems.clicked.connect(self.addItems)
self.btnPrintItems = QtWidgets.QPushButton()
self.btnPrintItems.setText('print the total number of checked items')
self.vlayout.addWidget(self.btnPrintItems)
self.btnPrintItems.clicked.connect(self.printItems)
