花了两三天没有搞出来想要的效果。求求大家帮帮小白
花了两三天时间在学习这个效果，一直搞不出来，求大神们帮帮小白。1.我的想法；第一步：点击打开按钮，就可以导入文件夹的文件到listView中显示，同时文件夹的路径显示在line text里。
第二步：选中listView的项目，点击删除按钮，将其删除。
2.碰到的难点：1.在第一步从文件夹中导入，不会设置过滤只导入文件进来；
2.第二步，我想的是选中后才可以删除，
现在做出来的效果，选中后单击可以删除，不选中，单击删除也可以删除。

self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
_translate = QtCore.QCoreApplication.translate
Form.setWindowTitle(_translate("Form", "Form"))
self.pushButton.setText(_translate("Form", "打开"))
self.pushButton_2.setText(_translate("Form", "删除"))
逻辑代码：
# -*- encoding:utf-8 -*-
import os,sys
from Pratics.UiView.MainView1 import Ui_Form
from PyQt5.QtWidgets import QWidget,QFileDialog,QMainWindow,QApplication
from PyQt5.QtCore import QStringListModel
class Function(QWidget,Ui_Form):
def __init__(self):
super(Function, self).__init__()
self.setupUi(self)
self.pushButton.clicked.connect(self.openfiles)
self.listView.clicked.connect(self.currentIndex)
self.pushButton_2.clicked.connect(self.deleteItem)
def openfiles(self):
dir_path=QFileDialog.getExistingDirectory(None,"选择文件",os.getcwd())
self.lineEdit.setText(dir_path) #路径写入到文本框内
self.list =os.listdir(dir_path) #获取路径下面文件列表
self.listmodel =QStringListModel()
self.listmodel.setStringList(self.list)
self.listView.setModel(self.listmodel)
def currentIndex(self):
self.a=self.listView.currentIndex().row()#获取当前项目行号
print("bbb")
def deleteItem(self):
self.listmodel.removeRow(self.a)
if __name__=="__main__":
app =QApplication(sys.argv)
win =Function()
win.show()
sys.exit(app.exec_())
请大家给我指导一下如何实现我的两个想法。。。
