plotting on PyQt6

问题

这是您提供的代码的翻译部分：

  1. 我之前在这里写过，但我删除了问题，因为没有具体信息。现在我会重新提出。
  2. 我有一个使用PyQt6开发的应用程序。它包含三个用于切换的按钮：如果您单击“2页”按钮，将显示两个带有“2页”标签的页面，类似于“3页”按钮。问题是：第一页应该显示一个绘图，但我遇到了以下错误：
  3. `AttributeError: 'QWidget' object has no attribute 'plot'。`
  5. 我对面向对象编程还不太擅长，所以我不太明白如何修复它。我使用pyqtgraph库进行绘图。
  6. 由Qt Designer生成的代码。
  8. 这是我编写的逻辑代码。
  10. ```python
  11. import sys
  12. from PyQt6 import QtWidgets, QtGui, QtCore
  13. from untdwdfd import Ui_MainWindow
  14. from pyqtgraph import PlotWidget
  15. import pyqtgraph as pg
  17. class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
  18.     def __init__(self):
  19.         super().__init__()
  20.         self.setupUi(self)
  21.        
  22.         QtCore.QMetaObject.connectSlotsByName(self)
  24.         self.pizdec.plot([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])
  25.         
  26.     @QtCore.pyqtSlot()
  27.     def on_pushButton_clicked(self):
  28.         self.graph.setCurrentIndex(0)
  30.     @QtCore.pyqtSlot()
  31.     def on_pushButton_3_clicked(self):
  32.         self.graph.setCurrentIndex(1)
  34.     @QtCore.pyqtSlot()
  35.     def on_pushButton_2_clicked(self):
  36.         self.graph.setCurrentIndex(2)
  39. if __name__ == '__main__':
  40.     app = QtWidgets.QApplication(sys.argv)
  41.     window = MainWindow()
  42.     window.show()
  43.     sys.exit(app.exec())

I already wrote here before, but I deleted the question, because there were no specifics. Now I'll bring it in.
I have an application that I have developed in PyQt6. It contains three buttons for switching: if you click on the " 2 page" button, there will be 2 pages with the inscription 2 page and similarly with the "3 page" button. The question is: page 1 should display a plot, in the pizdec area, however I get the following error:
AttributeError: 'QWidget' object has no attribute 'plot'.

I'm not really good at OOP yet, so I don't quite understand how to fix it. For plotting i use pyqtgraph library.

If you look at your UI file you might notice that self.pizdec is defined as a QWidget.

如果你查看你的 UI 文件，你可能会注意到 self.pizdec 被定义为一个 QWidget。

And then in your logic file you are calling:

然后在你的逻辑文件中，你调用了：

You are receiving the error because QWidget doesn't have a plot method.

你收到了错误，因为 QWidget 没有 plot 方法。

You technically shouldn't edit the uic files, so what you can do is edit your UI in designer and leave an empty space where self.pizdec is and then add the widget in your logic file.

从技术上讲，你不应该编辑 uic 文件，所以你可以在设计师中编辑你的 UI，在 self.pizdec 的位置留出一个空白空间，然后在你的逻辑文件中添加小部件。

For example:

例如：

  1. import sys
  2. from PyQt6 import QtWidgets, QtGui, QtCore
  3. from untdwdfd import Ui_MainWindow
  4. from pyqtgraph import PlotWidget
  5. import pyqtgraph as pg
  7. class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
  8.     def __init__(self):
  9.         super().__init__()
  10.         self.setupUi(self)
  12.         QtCore.QMetaObject.connectSlotsByName(self)
  13.         self.pizdec = PlotWidget(parent=self.page)
  14.         self.pizdec.setGeometry(QtCore.QRect(70, 20, 1231, 441))
  15.         self.pizdec.setObjectName("pizdec")
  16.         self.pizdec.plot([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])
  18.     @QtCore.pyqtSlot()
  19.     def on_pushButton_clicked(self):
  20.         self.graph.setCurrentIndex(0)
  22.     @QtCore.pyqtSlot()
  23.     def on_pushButton_3_clicked(self):
  24.         self.graph.setCurrentIndex(1)
  26.     @QtCore.pyqtSlot()
  27.     def on_pushButton_2_clicked(self):
  28.         self.graph.setCurrentIndex(2)
  30. if __name__ == '__main__':
  31.     app = QtWidgets.QApplication(sys.argv)
  32.     window = MainWindow()
  33.     window.show()
  34.     sys.exit(app.exec())
