我在创建PyQt5 GUI主.py文件这是一个主要的应用程序文件夹中。在界面文件中,一个按钮启动了一个名为 Calculation 的新类(在文件 entry.py 中),传入页面上多个输入的值,并在该类中调用 startCalculation() 方法。在这个方法中,不同的变量被传递给导入的python文件中的方法,然后这些计算的结果被返回并传递给另一个python文件中的下一个计算。这些返回值是包含值的数组形式(对于 y 轴,然后使用 numpy 和 plotly 显示)。
当我运行应用程序并单击主界面中的按钮时,应用程序开始加载(Mac 上的彩虹动画)并且它说它没有响应。这不是类本身的问题,因为正常的打印测试在 startCalculation() 方法中工作,但来自导入文件的函数导致这种情况发生。此外,终端中没有给出任何错误。
以下是PyQt接口文件(main .py)中的代码
from app import entry
def startButton(self):
massaTotale = float(self.lineEdit.text())
dragCoefficient = float(self.lineEdit_5.text())
liftCoefficient = float(self.lineEdit_6.text())
powerAvionics = float(self.lineEdit_3.text())
powerPayload = float(self.lineEdit_4.text())
airSpeed = float(self.lineEdit_8.text())
valoreUnico = float(self.valoreUnicoEdit.text())
engineEfficiency = float(self.lineEdit_9.text())
turbolenceCoeff = float(self.lineEdit_10.text())
dayOfYear = float(self.day_LineEdit.text())
latitude = float(self.latitude_LineEdit.text())
sunsetHourAngle = float(self.sunsetHourAngle_LineEdit.text())
declination = float(self.declination_LineEdit.text())
newCaluclation = entry.Calculation(massaTotale, dragCoefficient, liftCoefficient, powerAvionics, powerPayload, airSpeed, valoreUnico, engineEfficiency, turbolenceCoeff, dayOfYear, latitude, sunsetHourAngle, declination)
newCaluclation.startCalculation()
这是调用外部文件中函数的类中的代码
from app.mainFunctions import pLevel
#constructor method
def __init__(self, massaTotale, dragCoefficient, liftCoefficient, powerAvionics, powerPayload, airSpeed, valoreUnico, efficiencyEngine, turbolenceCoeff, dayOfYear, latitude, sunsetHourAngle, declination):
# calculate plevel

self.vair = airSpeed
self.cl = liftCoefficient
self.cd = dragCoefficient
self.efficiencyEngine = efficiencyEngine
self.valoreUnico = valoreUnico
self.powerAvionics = powerAvionics
self.powerPayload = powerPayload
self.turbolenceCoeff = turbolenceCoeff
self.day_of_year = dayOfYear
self.latitude = latitude
self.sunset_hour_angle = sunsetHourAngle
self.declination = declination
#starting the calculation
def startCalculation(self):
self.x_values, self.pLevel_values = pLevel.calculate_pLevel(self.valoreUnico, self.cd, self.cl, self.totM)
'''
self.pEngine_values = pEngine.calculate_pEngine(self.x_values, self.pLevel_values, self.efficiencyEngine, self.turbolenceCoeff)
self.pOut_values = pOut.calculate_pOut(self.x_values, self.pEngine_values, self.powerAvionics, self.powerPayload)
self.I_loctime = I_loctime.calculate_I_loctime(self.day_of_year, self.latitude, self.sunset_hour_angle, self.declination)
self.asm_values = area_Solar_Module.calculate_asm(self.x_values, self.pOut_values, self.I_loctime)
'''
pLevel.py 文件中包含以下代码,并应返回要传递给条目 Calculation 类文件中的第二个函数的值数组。
import math
import numpy as np
import plotly as py
import plotly.graph_objs as go

# calculating pLevel

)
def calculate_pLevel(valoreUnico, cd, cl, totM):

count = count + 0.01
y_values = []
iteration = 0
while (iteration < len(x_values)):
x_value = x_values[iteration]
if (x_value == 0):
y_value = 0
y_values.append(y_value)
else:
if (valoreUnico == 0.0):
# nessun dato per valoreUnico dato, utilizza i due valori separati
y_value = firstPart(cd, cl) * math.sqrt(secondPart(x_value, totM))
y_values.append(y_value)
else:
y_value = valoreUnico * \
math.sqrt(secondPart(x_value, totM))
y_values.append(y_value)
iteration = iteration + 1
else:
yNpArray = np.array(y_values)
xNpArray = np.array(x_values)
tracePLevel = go.Scatter(
x=xNpArray,
y=yNpArray,
mode='lines',
name='pLevel',
line=dict(
shape='spline'
)
)
figPLevel = go.Figure(data=[tracePLevel], layout=layoutPLevel)
figPLevel.show()
return x_values, y_values
def firstPart(cd, cl):
return (cd / cl**(3/2))
def secondPart(x_value, totM):
return (2*(totM * 9.81)**3) / (1.225 * x_value)
文件的结构如下:
-app
-- __main__.py
-- entry.py
-- __init__.py
-- mainFunctions
--- pLevel.py
--- __init__.py
pLevel 函数中 x_values 的循环没有在迭代中添加 1,因此循环一直持续下去。我只是没有注意到我的错误。
而不是
while (iteration < len(x_values)):
x_value = x_values[iteration]
if (x_value == 0):
y_value = 0
y_values.append(y_value)
它应该是
while (iteration < len(x_values)):
x_value = x_values[iteration]
if (x_value == 0):
y_value = 0
y_values.append(y_value)
iteration = iteration+1
