这是我的 gui 代码，我想在 headwidget 中添加以下文件，文件名为 hudsup.py：
import sys
import math
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *
def rec_line_cord(i,list,xc,origin_list,pitch,roll):
.
.
def rec_drawLine(self,i,list,painter,roll,metrics):
.
.
.
def drawMarkings(self, painter):
.
.
.
def drawNeedle(self, painter,roll):
.
.
.
def Compass(self,painter,yaw,r):
.
.
.
class Manager(QObject):
changedValue = pyqtSignal(tuple)
def __init__(self):
QObject.__init__(self)
filename = "Attitude_data_Manual_1232018_1158.txt"
res = self.read_content(filename)
self.results = zip(*res)
self.timer = QTimer(self)
self.timer.timeout.connect(self.update_value)
self.timer.start(100)
@pyqtSlot()
def update_value(self):
try:
self.changedValue.emit(next(self.results))
except StopIteration:
self.timer.stop()
def read_content(self, filename):
.
.
.
class Widget(QWidget):
def __init__(self, parent=None):
QWidget.__init__(self, parent)
self.v = None
@pyqtSlot(tuple)
def update_value(self, v):
self.v = v
self.update()
def paintEvent(self, event):
QWidget.paintEvent(self, event)
painter = QPainter(self)
r = self.rect()
.
.
if __name__ == '__main__':
app = QApplication(sys.argv)
manager = Manager()
w = Widget()
manager.changedValue.connect(w.update_value)
w.show()
sys.exit(app.exec_())
这是我的 python 脚本示例。 这是 hudsup.py 输出： animated huds_up display
我的用户界面看起来像这样，我希望我的 hudsup 像上面提到的那样显示： Gui
【问题讨论】：
【参考方案1】：您不应该直接使用生成的代码，而是创建一个新的小部件类并从它继承：
class MainWindow(Ui_MainWindow, QMainWindow):
def __init__(self):
Ui_MainWindow.__init__(self)
QMainWindow.__init__(self)
self.setupUi(self)
要集成您的第二个小部件，您可以像现在一样将其添加到Heads_up，但不需要调用exec_：
self.hud_sup = HudSup()
self.Heads_up.addWidget(self.hud_sup)
【讨论】：
是的，我发布的这段代码应该可以工作，你试过了吗？ 不，它不起作用..我收到此错误：回溯（最近一次调用最后一次）：文件“layproject.py”，第 142 行，在以上是关于如何在pyqt5 ui小部件代码中使用python脚本的主要内容，如果未能解决你的问题，请参考以下文章
