如何在 pyqt 中向 Qtablewidget 添加布局? [英] How do I add a layout to a Qtablewidget in pyqt?

问题描述

我的 qtablewidget 定义如下:

I have my qtablewidget defined like this:

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像我希望的那样安静地工作.我是pyqt的初学者.我之前在 qlistview 上尝试过这种布局，效果很好.

I would like my end result to look something similar to the pic below but right now, the layout that I'm trying to add doesn't quiet work the way I'd like it to. I'm a beginner at pyqt. I've tried this layout before on a qlistview and it worked well.

推荐答案

add {your table}.table.horizo​​ntalHeader().setStretchLastSection(True) 和/或 {your table}.verticalHeader().setStretchLastSection(True)

import sys

from PyQt4 import QtGui
from PyQt4 import QtCore


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_())
