Question

我有一个带有菜单和mdiArea的QMainWindow。当我单击菜单项时，我需要显示一个qDialog，例如带有一个数据列表。

我想用数据列表作为自己的类来构建QDialog。但是，我不知道如何将其作为子窗口附加到mdiArea。能否举一个小例子说明如何做到这一点？

import sys
from PyQt5.QtCore import pyqtSlot
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.uic import loadUi

class CliDataBrowser(QDialog):
    def __init__(self,parent=None):
    super(CliDataBrowser,self).__init__(parent)
    loadUi("CliReportsUI/clidata_browser.ui",self)


class MainApplication(QMainWindow):
    def __init__(self,*args):
        super(MainApplication,self).__init__(*args)
        loadUi("CliReportsUI/clireportmain.ui",self)

    @pyqtSlot()
    def on_mnu_close_triggered(self):
        sys.exit();

    @pyqtSlot()
    def on_mnu_master_triggered(self):
        dataBrowser = CliDataBrowser(self) # <--- Need this to be a mdi subwindow
        dataBrowser.show()


app = QApplication(sys.argv)
mainWin = MainApplication()
mainWin.show()
sys.exit(app.exec_())

clireportmain.ui：
