是否可以在布局中水平添加QTableWidget

Question

我写了一段代码，将问题与分数表并排打印。但是，当尝试使用QHBoxLayout(如果运行(显示表时，不会显示该表，但不会显示任何错误。另一方面，当使用QVBoxLayout时，它会在我运行代码时显示出来。我可以把问题/答案框并排(水平(放在桌子上吗？拆分器是否可以作为一种替代方案，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心小部件。然后添加一个水平布局，并将小部件添加到该布局中。

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)

完整的示例：(使用PySide进行了测试，但在pyqt中应该相同(

        super(StartTest, self).__init__(parent)
        self.stack = QtGui.QStackedWidget(self)
        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)
