pyqt5的窗口设计
在这里我是先使用qt设计师设计出主界面（main）基本的样子，再使用css对界面进行美化，代码如下
'''
` MainWindow.setObjectName("MainWindow")
MainWindow.resize(505, 615)
MainWindow.setToolButtonStyle(QtCore.Qt.ToolButtonIconOnly)
self.centralwidget = QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.pushButton = QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(22, 10, 89, 31))
self.pushButton.setObjectName("pushButton")
self.pushButton.clicked.connect(self.openmp4)
self.pushButton.setStyleSheet('''QPushButton{background:#F7D674;border-radius:5px;}QPushButton:hover{background:yellow;}''')
self.groupBox = QtWidgets.QGroupBox(self.centralwidget)
self.groupBox.setGeometry(QtCore.QRect(22, 50, 452, 351))
self.groupBox.setObjectName("groupBox")
self.widget = QtWidgets.QWidget(self.groupBox)
self.widget.setGeometry(QtCore.QRect(11, 20, 430, 291))
self.widget.setObjectName("widget")
self.gridLayout_3 = QtWidgets.QGridLayout(self.widget)
self.gridLayout_3.setObjectName("gridLayout_3")
self.label = QLabel(self)
self.label.resize(400, 300)
self.label.setText("Waiting for video...")
self.gridLayout_3.addWidget(self.label)
self.close_widget = QtWidgets.QWidget(self.centralwidget)
self.close_widget.setGeometry(QtCore.QRect(420, 0, 93, 41))
self.close_widget.setObjectName("close_widget")
self.close_layout = QGridLayout() # 创建左侧部件的网格布局层
self.close_widget.setLayout(self.close_layout) # 设置左侧部件布局为网格
self.left_close = QPushButton("") # 关闭按钮
self.left_close.clicked.connect(self.close)
self.left_visit = QPushButton("") # 空白按钮
#self.left_visit.clicked.connect(MainWindow.big)
self.left_mini = QPushButton("") # 最小化按钮
self.left_mini.clicked.connect(MainWindow.mini)
self.close_layout.addWidget(self.left_mini, 0, 0, 1, 1)
self.close_layout.addWidget(self.left_close, 0, 2, 1, 1)
self.close_layout.addWidget(self.left_visit, 0, 1, 1, 1)
self.left_close.setFixedSize(15, 15) # 设置关闭按钮的大小
self.left_visit.setFixedSize(15, 15) # 设置按钮大小
self.left_mini.setFixedSize(15, 15) # 设置最小化按钮大小
self.left_close.setStyleSheet(
'''QPushButton{background:#F76677;border-radius:5px;}QPushButton:hover{background:red;}''')
self.left_visit.setStyleSheet(
'''QPushButton{background:#F7D674;border-radius:5px;}QPushButton:hover{background:yellow;}''')
self.left_mini.setStyleSheet(
'''QPushButton{background:#6DDF6D;border-radius:5px;}QPushButton:hover{background:green;}''')
self.horizontalLayout = QtWidgets.QHBoxLayout(self.close_widget)
self.horizontalLayout.setContentsMargins(0, 0, 0, 0)
self.horizontalLayout.setObjectName("horizontalLayout")
self.pushButton_2 = QtWidgets.QPushButton(self.centralwidget)
self.pushButton_2.setGeometry(QtCore.QRect(77, 440, 133, 41))
self.pushButton_2.setObjectName("pushButton_2")
self.pushButton_2.clicked.connect(self.play)
self.pushButton_2.setStyleSheet(
'''QPushButton{background:#6DDF6D;border-radius:5px;}QPushButton:hover{background:green;}''')
self.pushButton_3 = QtWidgets.QPushButton(self.centralwidget)
self.pushButton_3.setGeometry(QtCore.QRect(308, 440, 111, 41))
self.pushButton_3.setObjectName("pushButton_3")
self.pushButton_3.clicked.connect(self.close_wall)
self.pushButton_3.setStyleSheet(
'''QPushButton{background:#F76677;border-radius:5px;}QPushButton:hover{background:red;}''')
self.pushButton_4 = QtWidgets.QPushButton(self.centralwidget)
self.pushButton_4.setGeometry(QtCore.QRect(187, 540, 133, 21))
self.pushButton_4.setObjectName("pushButton_4")
self.pushButton_4.clicked.connect(self.openurl)
self.pushButton_4.setStyleSheet(
'''QPushButton{background:#222225;color:white;border-radius:5px;}QPushButton:hover{background:#222225;color:skyblue}''')
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtWidgets.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 505, 23))
self.menubar.setObjectName("menubar")
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtWidgets.QStatusBar(MainWindow)
self.statusbar.setObjectName("statusbar")
MainWindow.setStatusBar(self.statusbar)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
self.centralwidget.setStyleSheet('''
QWidget#centralwidget{
color:white;

border-top:1px solid #222225;

''')
self.groupBox.setStyleSheet('''
color:white
''')
MainWindow.setWindowOpacity(0.95) # 设置窗口透明度
MainWindow.setAttribute(Qt.WA_TranslucentBackground)
MainWindow.setWindowFlag(Qt.FramelessWindowHint) # 隐藏边框```
两个分开的文件的链接
由于pyqt5的多开比较麻烦，所以我们分开了两个文件
由于时间比较匆忙，所以链接他们的只有一个文件和几段代码
if path == '':
reply = QtWidgets.QMessageBox.question(self, '提示',
"你选了个寂寞",
QtWidgets.QMessageBox.Yes)
return
with open("./filename.txt", 'w', encoding='utf-8') as f:
f.truncate(0)
print(f.write(str(path)))
try:
try:
call('taskkill /F /IM play.exe')
except:
pass
try:
os.system('start play.exe')
pass
except Exception as e:
print (e)
调用win32api
在这里十分感谢B站up主“我ID变绿了”，win32api的调用是他所提供的，代码如下：
hwnd = win32gui.FindWindow("Progman", "Program Manager")
win32gui.SendMessageTimeout(hwnd, 0x052C, 0, None, 0, 0x03E8)
hwnd_WorkW = None
while 1:
hwnd_WorkW = win32gui.FindWindowEx(None, hwnd_WorkW, "WorkerW", None)
print('hwmd_workw: ', hwnd_WorkW)
if not hwnd_WorkW:
continue
hView = win32gui.FindWindowEx(hwnd_WorkW, None, "SHELLDLL_DefView", None)
print('hwmd_hView: ', hView)
if not hView:
continue
h = win32gui.FindWindowEx(None, hwnd_WorkW, "WorkerW", None)
print('h_1: ',h)
while h:
win32gui.SendMessage(h, 0x0010, 0, 0) # WM_CLOSE
h = win32gui.FindWindowEx(None, hwnd_WorkW, "WorkerW", None)
print(h)
break
return hwnd
视频文件的播放
在视频播放方面我最先是使用C写了一个播放器，但后来发现用python的cv2比较快，所以我使用了cv2，代码如下
try:
global path
path, filetype = QFileDialog.getOpenFileName(None, "选择文件", '.',
"视频文件(*.AVI;*.mov;*.rmvb;*.rm;*.FLV;*.mp4;*.3GP)") # ;;All Files (*)
if path == "": # 未选择文件
return
self.slotStart()
t = Thread(target=self.Stop)
t.start() # 启动线程，即让线程开始执行
except Exception as e:
print (e)
def Stop(self):
""" Slot function to stop the programme
"""
sleep(30)
if self.cap != []:
self.cap.release()
self.timer_camera.stop() # 停止计时器
else:
Warming = QMessageBox.warning(self, "Warming", "Push the left upper corner button to Quit.",QMessageBox.Yes)
def slotStart(self):
""" Slot function to start the progamme
"""
videoName = path
if videoName != "": # “”为用户取消
self.cap = cv2.VideoCapture(videoName)
self.timer_camera.start(50)
self.timer_camera.timeout.connect(self.openFrame)
def openFrame(self):
""" Slot function to capture frame and process it
"""
if (self.cap.isOpened()):
ret, self.frame = self.cap.read()
if ret:
frame = cv2.cvtColor(self.frame, cv2.COLOR_BGR2RGB)
if self.detectFlag == True:
# 检测代码self.frame
self.label_num.setText("There are " + str(5) + " people.")
height, width, bytesPerComponent = frame.shape
bytesPerLine = bytesPerComponent * width
q_image = QImage(frame.data, width, height, bytesPerLine,
QImage.Format_RGB888).scaled(self.label.width(), self.label.height())
self.label.setPixmap(QPixmap.fromImage(q_image))
else:
self.cap.release()
self.timer_camera.stop() # 停止计时器
在线资源调用火萤的网页，也算是白嫖了吧
