Question

我有一个gui文件，我用qtdesigner设计它，还有另一个py文件。我尝试更改按钮名称或尝试在listwidget中添加项目，但我没有做到这一点。我收到了一条错误消息。

我的代码;

from gui import Ui_mainWindow
import sys
from PyQt5 import QtCore, QtGui, QtWidgets
import main


class Music(QtWidgets.QMainWindow, Ui_mainWindow):
    def __init__(self):
        super().__init__()
        self.setupUi(self)
        self.search_button.clicked.connect(self.searchbutton)

    def searchbutton(self):
        base = main.Main()
        self.url = base.search(self.search_box.text())
        self.dict = base.get_data(self.url)
        print(self.dict)
        for i in self.dict:
        self.setupUi.self.listWidget.addItem(i)


app = QtWidgets.QApplication(sys.argv)
gui = Music()
gui.show()
sys.exit(app.exec_())

和gui.py

from PyQt5 import QtCore, QtGui, QtWidgets

class Ui_mainWindow(object):
    def setupUi(self, mainWindow):
        mainWindow.setObjectName("mainWindow")
        mainWindow.resize(413, 613)
        mainWindow.setMinimumSize(QtCore.QSize(413, 613))
        mainWindow.setMaximumSize(QtCore.QSize(413, 613))
        mainWindow.setAutoFillBackground(False)
        self.centralwidget = QtWidgets.QWidget(mainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.musics_frame = QtWidgets.QFrame(self.centralwidget)
        self.musics_frame.setGeometry(QtCore.QRect(-1, 49, 411, 441))
        self.musics_frame.setFrameShape(QtWidgets.QFrame.StyledPanel)
        self.musics_frame.setFrameShadow(QtWidgets.QFrame.Raised)
        self.listWidget = QtWidgets.QListWidget(self.musics_frame)
        self.listWidget.setGeometry(QtCore.QRect(10, 10, 391, 421))
        self.listWidget.setIconSize(QtCore.QSize(5, 5))
        self.listWidget.setGridSize(QtCore.QSize(5, 5))
        self.listWidget.setViewMode(QtWidgets.QListView.IconMode)
        self.listWidget.setObjectName("listWidget")
        #  ....
        #  ....
        #  ....

和我的错误消息

  File "/home/yavuz/Genel/youtube-sounds/music.py", line 19, in searchbutton
    self.setupUi.self.listWidget.addItem(i)
    AttributeError: 'function' object has no attribute 'self'

当您将ui类用作mixin时，Qt Designer中的所有小部件都将作为Music类的实例属性添加。所以你只想要：

    self.listWidget.addItem(i)

PS：并将图标/网格大小设置为合理的（例如32 x 32），否则列表项将太小而无法看到。

AttributeError：＆＃39;功能＆＃39;对象没有属性＆＃39; self＆＃39;
