python - 如何在 pyqt 中向 Qtablewidget 添加布局？

Question

我的 qtablewidget 定义如下:

def __init__(self, parent = None):
        super(Window, self).__init__(parent)
        QtGui.QWidget.__init__(self)
        QtGui.QTableWidget.setMinimumSize(self, 500, 500)
        QtGui.QTableWidget.setWindowTitle(self, "Custom table widget")
        self.table = QtGui.QTableWidget()
        rowf = 3
        self.table.setColumnCount(3)
        self.table.setRowCount(rowf)
        self.table.setHorizontalHeaderItem(0, QtGui.QTableWidgetItem("col1"))
        self.table.setHorizontalHeaderItem(1, QtGui.QTableWidgetItem("col2"))
        self.table.setHorizontalHeaderItem(2, QtGui.QTableWidgetItem("col3"))
        self.table.verticalHeader().hide()

        header = self.table.horizontalHeader()
        header.setResizeMode(0, QtGui.QHeaderView.ResizeToContents)
        header.setResizeMode(1, QtGui.QHeaderView.ResizeToContents)
        header.setResizeMode(2, QtGui.QHeaderView.ResizeToContents)

        self.buttonBox = QtGui.QDialogButtonBox(self)
        self.buttonBox.setOrientation(QtCore.Qt.Horizontal)
        self.buttonBox.setStandardButtons(QtGui.QDialogButtonBox.Cancel | QtGui.QDialogButtonBox.Ok)

        self.verticalLayout = QtGui.QVBoxLayout(self)
        self.verticalLayout.addWidget(self.table)
        self.verticalLayout.addWidget(self.buttonBox)

        self.buttonBox.accepted.connect(self.close)
        self.buttonBox.rejected.connect(self.close)

我希望我的最终结果看起来类似于下图，但现在，我尝试添加的布局并没有按照我希望的方式安静地工作。我是 pyqt 的初学者。我之前在 qlistview 上尝试过这种布局，效果很好。

添加{您的表格}.table.horizo​​ntalHeader().setStretchLastSection(True)和/或{您的表格}.verticalHeader().setStretchLastSection(True)

import sys

from PyQt4 import QtGui

class Window(QtGui.QWidget):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent=parent)
        QtGui.QTableWidget.setMinimumSize(self, 500, 500)
        QtGui.QTableWidget.setWindowTitle(self, "Custom table widget")
        self.table = QtGui.QTableWidget()
        rowf = 3
        self.table.setColumnCount(3)
        self.table.setRowCount(rowf)
        self.table.setHorizontalHeaderItem(0, QtGui.QTableWidgetItem("col1"))
        self.table.setHorizontalHeaderItem(1, QtGui.QTableWidgetItem("col2"))
        self.table.setHorizontalHeaderItem(2, QtGui.QTableWidgetItem("col3"))
        self.table.horizontalHeader().setStretchLastSection(True)
        # self.table.verticalHeader().setStretchLastSection(True)

        self.buttonBox = QtGui.QDialogButtonBox(self)
        self.buttonBox.setOrientation(QtCore.Qt.Horizontal)
        self.buttonBox.setStandardButtons(QtGui.QDialogButtonBox.Cancel | QtGui.QDialogButtonBox.Ok)

        self.verticalLayout = QtGui.QVBoxLayout(self)
        self.verticalLayout.addWidget(self.table)
        self.verticalLayout.addWidget(self.buttonBox)

        self.buttonBox.accepted.connect(self.close)
        self.buttonBox.rejected.connect(self.close)

if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    w = Window()
    w.show()
    sys.exit(app.exec_())
