用qt做python界面设计_python QT5 子界面的设计
主界面为Main Window；子界面为Dialog。不同出现同级的两个
画界面简单，麻烦的是调取子界面。学习了几天，收获了两种方法，共享一下。不喜勿喷。
第一种：(主要看运行部分的调用，使用的是按钮来触发子界面)
from PyQt5.QtCore import QTimer,Qt,pyqtSignal, QObject
from PyQt5.QtGui import QImage, QPixmap,QMovie
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QFileDialog,QTabWidget, QMessageBox,QDesktopWidget, QLabel, QGridLayout
from jiemian_zhu import Ui_MainWindow
from jiemian_fu import Ui_Dialog
import time
import sys
import numpy as np
import cv2
class mywindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self):
super(mywindow, self).__init__()
# self.setupUi(self)
# QMainWindow.__init__(self)
self.main_ui = Ui_MainWindow()
self.main_ui.setupUi(self)
class childwindow(QtWidgets.QDialog, Ui_Dialog):
def __init__(self):
super(childwindow, self).__init__()
self.child = Ui_Dialog()
self.child.setupUi(self)
if __name__ == "__main__":
app=QtWidgets.QApplication(sys.argv)
ui = mywindow()
ui.setWindowTitle(Simple)
#开子界面，点击弹出子界面
child =childwindow()
push=ui.main_ui.pushButton
push.clicked.connect(child.show)
ui.show()
sys.exit(app.exec_())
第二种：在Main Window中的(如上myWindow中调用)
class childWindow(QtWidgets.QDialog,Ui_Dialog):
def __init__(self):
super(childWindow, self).__init__()
self.setupUi(self)
class mywindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self):
super(mywindow, self).__init__()
self.setupUi(self)
self.second_window = childWindow() # 实例化子界面
self.actionjigou.triggered.connect(self.xianshiqwe) # 槽函数连接
def xianshiqwe(self):
self.second_window.show()
主要差别就是在一个在类中调用。我是做的时候发现出了点问题，记录下来，共享。大佬勿喷
