恢复PyQt5的QWidgets所有子类自动显示功能
昨晚上，在eric6下面把一个正常的MainWindow的ui文件编译成.py文件。打开代码，在里面加了一句self.menubar.hide()，之后我其他所有的.py文件的按钮啊，QLabel啊所有的QWidgets子类全部不能显示，具体看下面的代码：
import sys
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
class window(QWidget):
def __init__(self,parent=None):
super(window,self).__init__(parent)
self.setWindowTitle("QMessage例子")
self.resize(300,200)
self.signal1 =pyqtSignal()
self.signal2 = pyqtSignal()
self.btn1=QPushButton("按钮1")
self.btn2=QPushButton("按钮2")
self.btn1.clicked.connect(self.messageMention1)
self.btn2.clicked.connect(self.messageMention2)
layout =QVBoxLayout()
layout.addWidget(self.btn1)
layout.addWidget(self.btn2)
self.setLayout= (layout)
def messageMention1(self):
reply=QMessageBox.information(self,"点击啦","按了第一个按钮，我收到了",QMessageBox.Yes|QMessageBox.No,QMessageBox.Yes)
print(reply)
def messageMention2(self):
QMessageBox.information(self,"点击啦 ","按下了第二个按钮 ，我收到了",QMessageBox.Yes|QMessageBox.No,QMessageBox.Yes)
if __name__=="__main__":
app = QApplication(sys.argv)
myshow=window()
myshow.show()
sys.exit(app.exec_())
