问题描述
我的GUI可以正常工作，所有按钮等都可以正常工作，除了其中一个使用无限while循环，并且当我单击主代码中定义的按钮（开始）时，该按钮会冻结。你能帮助我吗？ 这是我的GUI代码：

from pyqtgraph import PlotWidget
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
Form = QtWidgets.QWidget()
ui = Ui_Form()
ui.setupUi(Form)
Form.show()
sys.exit(app.exec_())'''
这是我的主要代码：
tempf = []
shc = []
ser = serial.Serial('COM13',9600)
class SetUI_main(Ui_Form):
def __init__(self):
self.timer = QtCore.QTimer()
self.timer.timeout.connect(self.draw)
def draw(self):
time.sleep(0.5)
sh = 0
while True:
time.sleep(0.1)
data = ser.readline()
temp = float(data.decode())
sh += 0.6
shc.append(sh)
tempf.append(temp)
print(tempf)
#print(shc)
self.graphicsView.plot(tempf,shc)
def start(self):
s = 's'.encode('ascii')
ser.write(s)
print('Start')
self.timer.start(2000)
def connector(self):
self.pushButton_13.clicked.connect(self.start)
然后是运行代码：
''' 从PyQt5导入QtCore，QtGui，QtWidgets 从PyQt5.QtCore导入pyqtSignal，QThread 导入序列
from un import SetUI_main
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
Form = QtWidgets.QWidget()
from PyQt5.QtCore import pyqtSignal,QThread
ui = SetUI_main()
ui.setupUi(Form)
ui.connector()
Form.show()
sys.exit(app.exec_())
