Hi,
I would suggest a slightly different way of using the .ui files from Qt
Designer/Creator, and that is to dynamically load the .ui instead of
manually generating code using the pyuic tool. This way it's easier to
modify the .ui, and keep all the code separate.
Here's an example:
#!/usr/bin/env python3
import sys
from PyQt5 import QtCore, QtGui, QtWidgets, uic
import numpy as np
import pyqtgraph as pg
class PlotWindow(QtWidgets.QMainWindow):
def __init__(self):
super().__init__()
# Load GUI layout from .ui file (named same as this source file,
but with .ui extension)
uic.loadUi(__file__.split('.py')[0] + '.ui', self)
# Finish up the GUI and connections
self.lineEdit.setText("Some text")
self.pushButton.clicked.connect(self.pushButton_clicked)
self.pushButton_2.clicked.connect(self.pushButton_2_clicked)
# ...
# Store your data here in the class (instead of using global
variables)
self.y = np.random.normal(size=300)
self.curve1 = self.plotWidget.plot(self.y)
self.timer = pg.QtCore.QTimer()
self.timer.timeout.connect(self.update)
self.timer.start(40)
def pushButton_clicked(self):
self.statusbar.showMessage('pushButton clicked...')
def pushButton_2_clicked(self):
self.statusbar.showMessage('pushButton_2 clicked...')
def update(self):
self.y[:-1] = self.y[1:] # shift data in the array one sample left
# (see also: np.roll)
self.y[-1] = np.random.normal() # continua grafiacando a partir del
ultimo punto graficado
self.curve1.setData(self.y)
def main():
app = QtWidgets.QApplication(sys.argv)
mainwindow = PlotWindow()
mainwindow.show()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
and for completeness, here's the contents of the .ui file (name it same as
python source file above, but with .ui extension):
<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
<class>MainWindow</class>
<widget class="QMainWindow" name="MainWindow">
<property name="geometry">
<rect>
<x>0</x>

<widget class="PlotWidget" name="plotWidget"/>
</item>
</layout>
</widget>
</item>
</layout>
</widget>
<widget class="QMenuBar" name="menubar">
<property name="geometry">
<rect>
<x>0</x>
<y>0</y>
<width>800</width>
<height>19</height>
</rect>
</property>
</widget>
<widget class="QStatusBar" name="statusbar"/>
</widget>
<customwidgets>
<customwidget>
<class>PlotWidget</class>
<extends>QGraphicsView</extends>
<header>pyqtgraph</header>
</customwidget>
</customwidgets>
<resources/>
<connections/>
</ui>
Good luck!
