Question

我想将文件中的用户列表插入tablewidget或tableview的第一行。我目前正在尝试使用tablewidget。到目前为止，下面的代码是我在看到this帖子的答案后想出来的。基本上，如果你看一下图片，我会尝试做到这一点，然后我会添加一个确定按钮来执行操作。

from PyQt4 import QtGui, QtCore

class Window(QtGui.QWidget):
    def __init__(self, rows, columns):
        QtGui.QWidget.__init__(self)
        self.table = QtGui.QTableWidget(rows, columns, self)
        self.table.setHorizontalHeaderItem(0, QtGui.QTableWidgetItem("Users"))
        self.table.setHorizontalHeaderItem(1, QtGui.QTableWidgetItem("Delete User"))
        self.table.setHorizontalHeaderItem(2, QtGui.QTableWidgetItem("Delete User and Home"))
        self.table.verticalHeader().hide()
        header = self.table.horizontalHeader()
        header.setStretchLastSection(True)
        for column in range(columns):
            if column == 0:
                with open("users") as input:
                    if input is not None:
                        users = input.readlines()
                    for line in users:
                        users = QtGui.QTableWidgetItem(line)
                        print line
                    input.close()
            for row in range(rows):
                if column % 3:
                    item = QtGui.QTableWidgetItem('%d' % column)
                    item.setFlags(QtCore.Qt.ItemIsUserCheckable |
                                  QtCore.Qt.ItemIsEnabled)
                    item.setCheckState(QtCore.Qt.Unchecked)
                    self.table.setItem(row, column, item)
        self.table.itemClicked.connect(self.handleItemClicked)
        layout = QtGui.QVBoxLayout(self)
        layout.addWidget(self.table)
        self._list = []

    def handleItemClicked(self, item):
        if item.checkState() == QtCore.Qt.Checked:
            print('"%s" Checked' % item.text())
            self._list.append(item.row())
            print(self._list)
        else:
            print('"%s" Clicked' % item.text())

if __name__ == '__main__':

    import sys
    app = QtGui.QApplication(sys.argv)
    window = Window(6, 3)
    window.resize(400, 400)
    window.show()
    sys.exit(app.exec_())

以下代码可能会满足您的需求。它假定您有一个文件users.txt，每行包含一个名称，如

Harry
Sally
Wang
Jon
Leona

然后您需要读取该文件并删除换行符。

from PyQt4 import QtGui, QtCore

class Window(QtGui.QWidget):
    def __init__(self):
        QtGui.QWidget.__init__(self)
        with open("users.txt") as f:
            users = f.readlines()
            users = [user.split("\n")[0] for user in users]

        self.table = QtGui.QTableWidget(len(users), 2, self)
        self.table.setHorizontalHeaderLabels(["Delete User", "Delete Home"])
        self.table.setVerticalHeaderLabels(users)
        for column in range(2):
            for row in range(len(users)):
                item = QtGui.QTableWidgetItem("")
                item.setFlags(QtCore.Qt.ItemIsUserCheckable |
                                  QtCore.Qt.ItemIsEnabled)
                item.setCheckState(QtCore.Qt.Unchecked)
                self.table.setItem(row, column, item)
        self.table.itemClicked.connect(self.handleItemClicked)
        layout = QtGui.QVBoxLayout(self)
        layout.addWidget(self.table)
        self._list = []

    def handleItemClicked(self, item):
        if item.checkState() == QtCore.Qt.Checked:
            print('"%s" Checked' % item.text())
            self._list.append(item.row())
            print(self._list)
        else:
            print('"%s" Clicked' % item.text())

if __name__ == '__main__':

    import sys
    app = QtGui.QApplication(sys.argv)
    window = Window()
    window.resize(350, 300)
    window.show()
    sys.exit(app.exec_())

#How do I insert data from file in the first column of a qtablewidget or qtableview?

#This is the example code for insert data to Qtablewidget
#Please not the print result. I hope you can understand how to use columns and row values.
#I used the input data from "dictionary variable - self.input". You can replace this input variable to your input data.
#if any doubts regarding this below code, please let me know.
#If your are not expecting this answer, sorry.
#Thanks, Subin

如何在qtablewidget或qtableview的第一列中插入文件中的数据？
