标签: python pyqt5

我对 PyQt5 完全陌生,我正在尝试开发具有主菜单和子菜单的应用程序,但我不知道该如何开始。我发现的所有示例都使用该弹出窗口作为子菜单。

这是我要做什么的一个例子。请问如何在PyQt5中启动以及使用什么建议?

主菜单在右侧,子菜单在左侧

要创建主菜单,您可以在图标模式下使用QListWidget,并且可以使用QStackedLayout来交换页面:

import sys
from PyQt5 import QtCore, QtGui, QtWidgets

class Page(QtWidgets.QWidget):
    clicked = QtCore.pyqtSignal()

    def __init__(self, content, parent=None):
        super(Page, self).__init__(parent)
        lay = QtWidgets.QVBoxLayout(self)
        button = QtWidgets.QPushButton("Back")
        button.clicked.connect(self.clicked)
        lay.addWidget(button)
        lay.addWidget(content)


class Widget(QtWidgets.QWidget):
    def __init__(self, parent=None):
        super(Widget, self).__init__(parent)

        lay = QtWidgets.QVBoxLayout(self)
        self.stacked = QtWidgets.QStackedWidget()
        lay.addWidget(self.stacked)

        self.listWidget = QtWidgets.QListWidget()

        self.listWidget.setViewMode(QtWidgets.QListView.IconMode)
        self.listWidget.setIconSize(QtCore.QSize(128, 128))
        self.listWidget.itemClicked.connect(self.onItemClicked)
        self.stacked.addWidget(self.listWidget)

        for icon, content in [("alarms.png", QtWidgets.QTextEdit() ),
                              ("fitness.png", QtWidgets.QMdiArea() ),
                              ("navigation.png", QtWidgets.QTableWidget(4, 4) ),
                              ("notifications.png", QtWidgets.QListWidget() )]:

            p = Page(content)
            p.clicked.connect(lambda: self.stacked.setCurrentIndex(0))
            self.addPage(QtGui.QIcon(icon), p)

    def addPage(self, icon, widget):
        it = QtWidgets.QListWidgetItem()
        it.setIcon(icon)
        self.listWidget.addItem(it)
        self.stacked.addWidget(widget)
        it.setData(QtCore.Qt.UserRole, self.listWidget.count())

    def onItemClicked(self, it):
        ix = it.data(QtCore.Qt.UserRole)
        self.stacked.setCurrentIndex(ix)


if __name__ == '__main__':

    app = QtWidgets.QApplication(sys.argv)
    w = Widget()
    w.resize(640, 480)
    w.show()
    sys.exit(app.exec_())
