pyqt5 GUI中的窗口未打开

Question

我正在尝试使用Pyqt5创建一个GUI应用程序。我面临的问题是，代码运行良好，但记录窗户打不开。我附上了下面的整个代码和我所指的函数片段。我试着通读整个代码，但没有发现相同的任何缺陷。

import sys
from random import randint
from PyQt5.QtWidgets import QApplication, QLabel, QMainWindow, QPushButton, QVBoxLayout, QWidget
import time
#from libsonyapi.camera import Camera
#from libsonyapi.actions import Actions
#from pysony import SonyAPI, ControlPoint, common_header
#search = ControlPoint()
#cameras =  search.discover(1) 
#camera = SonyAPI(QX_ADDR=cameras[0])
# create camera instance
#camerass = Camera()

layout.addWidget(start_recording_button)
# THIS BUTTON IS USED TO STOP RECORDING #
stop_recording_button = QPushButton(" STOP RECORDING ")
stop_recording_button.clicked.connect(self.stop_recording)
layout.addWidget(stop_recording_button)

self.show()

def start_recording(self):
camerass.do(Actions.startMovieRec)

def stop_recording(self):
camerass.do(Actions.stopMovieRec)

# THIS BUTTON IS USED AS ZOOM IN #

函数是

class recording(QWidget):

def __init__(self):
super().__init__()
layout = QVBoxLayout(self)

# THIS BUTTON IS USED TO START RECORDING #
start_recording_button = QPushButton(" START RECORDING ")
start_recording_button.clicked.connect(self.start_recording)
layout.addWidget(start_recording_button)
# THIS BUTTON IS USED TO STOP RECORDING #
stop_recording_button = QPushButton(" STOP RECORDING ")
stop_recording_button.clicked.connect(self.stop_recording)
layout.addWidget(stop_recording_button)

self.show()

def start_recording(self):
camerass.do(Actions.startMovieRec)
time.sleep(2)
def stop_recording(self):
camerass.do(Actions.stopMovieRec)
time.sleep(2)

Answer 1

在您的代码中，您从未创建MainWindow3，其中记录类/窗口将在单击"RECORDING"后创建。按钮。

创建MainWindow3后，按下按钮后显示录制窗口。要测试这一点，只需替换

w = MainWindow()

w = MainWindow3()

在你的"main"(最后第三行)

Answer 2

我已经在我的系统中运行了它并做了一些更改。我正在粘贴下面的代码。
