python - 是否可以将 QTableWidget 水平添加到布局中？

Question

我编写了一段代码来与分数表并排打印问题。但是，当尝试使用 QHBoxLayout (如果运行)显示表格时，不会显示表格，但不会显示错误。另一方面，当使用 QVBoxLayout 时，它会在我运行代码时显示。我是否可以将表格与问题/答案框并排(水平)呈现？拆分器可以作为替代方案吗？如果可以，我如何在代码中实现它？

我的代码如下:

import sys, os, random
from PyQt4 import QtCore, QtGui
StudentNames = []
StudentScores = []

class StartTest(QtGui.QMainWindow):
    def __init__(self, questions, parent=None):
        global StudentNames
        global StudentScores
        super(StartTest, self).__init__(parent)
        self.stack = QtGui.QStackedWidget(self)
        self.setCentralWidget(self.stack)
        StudentNames.append('Hamzah Akhtar')
        StudentNames.append('Bob Marley')
        StudentNames.append('John Meadows')
        StudentScores.append(int(0))
        StudentScores.append(int(0))
        StudentScores.append(int(0))
        for index, question in enumerate(questions):
            page = Question(question, self)
            page.submit.clicked[()].connect(
                lambda index=index: self.handleSubmit(index))
            self.stack.addWidget(page)
        self.answers = []

    def handleSubmit(self, index):
        page = self.stack.widget(index)
        answer = page.answer.text()
        # validate submitted answer...
        self.answers.append(answer)
        if index < self.stack.count() - 1:
            self.stack.setCurrentIndex(index + 1)

class Question(QtGui.QWidget):
    def __init__(self, question, parent=None):
        global StudentNames
        global StudentScores
        super(Question, self).__init__(parent)
        self.Table = QtGui.QTableWidget()
        self.Table.setRowCount(3)
        self.Table.setColumnCount(1)
        self.Table.setVerticalHeaderLabels(StudentNames)
        self.Table.setHorizontalHeaderLabels(['Scores'])
        self.question = QtGui.QLabel(question, self)
        self.answer = QtGui.QLineEdit(self)
        self.submit = QtGui.QPushButton('Submit', self)
        form = QtGui.QFormLayout()
        form.addRow(self.question, self.answer)
        layout = QtGui.QVBoxLayout(self)
        layout.addLayout(form)
        layout.addWidget(self.submit)
        hlayout = QtGui.QHBoxLayout(self)
        hlayout.addLayout(layout)
        hlayout.addWidget(self.Table)
        self.setLayout(hlayout)

if __name__ == '__main__':
    User = ''
    app = QtGui.QApplication([])
    questions = [
        'What is 5+5?',
        'What is 45+10?',
        'What is 28+47?',
        'What is 22+13?',
        ]
    window = StartTest(questions)
    window.showFullScreen()
    app.exec_()

您可以将占位符小部件设置为中央小部件。然后添加水平布局并将小部件添加到该布局。

centralWidget = QtGui.QWidget(self)
self.setCentralWidget(centralWidget)
mainLayout = QtGui.QHBoxLayout(centralWidget)
self.scoreTable = QtGui.QTableWidget(self)
self.scoreTable.setRowCount(len(StudentNames))
self.scoreTable.setColumnCount(1)
self.scoreTable.setVerticalHeaderLabels(StudentNames)
self.scoreTable.setHorizontalHeaderLabels(['Scores'])
for i, score in enumerate(StudentScores):
    item = QtGui.QTableWidgetItem(str(score))
    self.scoreTable.setItem(i, 0, item)

mainLayout.addWidget(self.stack)
mainLayout.addWidget(self.scoreTable)

        StudentNames.append('Hamzah Akhtar')
        StudentNames.append('Bob Marley')
        StudentNames.append('John Meadows')
        StudentScores.append(int(0))
        StudentScores.append(int(0))
        StudentScores.append(int(0))
        for index, question in enumerate(questions):
            page = Question(question, self)
            page.submit.clicked[()].connect(
                lambda index=index: self.handleSubmit(index))
            self.stack.addWidget(page)

        answer = page.answer.text()
        # validate submitted answer...
        self.answers.append(answer)
        if index < self.stack.count() - 1:
            self.stack.setCurrentIndex(index + 1)
