Question

我有一个简单的pyqt UI，其中有一个表格小部件。我希望在调整主窗口大小时调整窗口小部件的大小。 stackOverflow（Resizing table columns when window is maximized）上发布了类似的问题，但给出的答案并没有解决我的目的。特别是我尝试使用@import '~@angular/material/theming'; $custom-light-blue: ( 50: #e1f5fe, 100: #b3e5fc, 200: #81d4fa, 300: #4fc3f7, 400: #29b6f6, 500: #3c3fcb, 600: #039be5, 700: #0288d1, 800: #0277bd, 900: #01579b, A100: #80d8ff, A200: #40c4ff, A400: #00b0ff, A700: #0091ea, contrast: ( 50: $black-87-opacity, 100: $black-87-opacity, 200: $black-87-opacity, 300: $black-87-opacity, 400: $black-87-opacity, 500: white, 600: white, 700: white, 800: white, 900: $white-87-opacity, A100: $black-87-opacity, A200: $black-87-opacity, A400: $black-87-opacity, A700: white, ) ); @include mat-core(); $candy-app-primary: mat-palette($custom-light-blue); $candy-app-accent: mat-palette($custom-light-blue, A200, A100, A400); $candy-app-warn: mat-palette($custom-light-blue); $candy-app-theme: mat-light-theme($candy-app-primary, $candy-app-accent, $candy-app-warn); @include angular-material-theme($candy-app-theme); 。它根据表窗口小部件几何图形调整表格的列宽，但在调整主窗口大小时不会调整窗口小部件的大小。我正在使用pyqt5和spyder IDE。

这是一个例子

self.tableWidget.horizontalHeader().setSectionResizeMode(QtWidgets.QHeaderView.Stretch)

试一试：

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(566, 475)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")

        self.horizontalLayout_2 = QtWidgets.QHBoxLayout(self.centralwidget)
        self.horizontalLayout_2.setObjectName("horizontalLayout_2")
        self.verticalLayout_2 = QtWidgets.QVBoxLayout()
        self.verticalLayout_2.setObjectName("verticalLayout_2")
        self.horizontalLayout_2.addLayout(self.verticalLayout_2)

        self.tableWidget = QtWidgets.QTableWidget(self.centralwidget)
        self.tableWidget.setObjectName("tableWidget")
        self.verticalLayout_2.addWidget(self.tableWidget)
        self.tableWidget.setWindowTitle("Transactional Data")
        self.tableWidget.setColumnCount(7)
        self.tableWidget.setRowCount(5)
        self.tableWidget.setAlternatingRowColors(True)
        self.tableWidget.setHorizontalHeaderLabels(['A','B','C','D','E','F','G']) 
        self.tableWidget.horizontalHeader().setSectionResizeMode(QtWidgets.QHeaderView.Stretch)

        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 24))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())
