PyQt QListWidget不会将自定义微件显示为项目
PyQt QListWidget不会将自定义微件显示为项目

我想将NodeLinkItemWidgetUI表单(自定义小部件)作为项目添加到我的主应用程序的ListWidget中。问题是，具有正确小部件大小的项目作为项目添加到列表中，但项目内容为空。以下是来自NodeLinkItemWidgetUI的项目自定义小部件的代码
from PySide2 import QtCore, QtGui, QtWidgets
class Ui_Form(QtWidgets.QWidget):
def __init__(self, nodename, nodeclass, parent=None):
super(Ui_Form,self).__init__(parent)
self.comboBox_type = QtWidgets.QComboBox()
self.comboBox_type.setGeometry(QtCore.QRect(10, 100, 51, 25))
self.comboBox_type.setCurrentText("connector")
self.comboBox_type.setObjectName("comboBox_type")
self.comboBox_type.addItem("")
self.comboBox_type.setItemText(0, "connector")
self.comboBox_type.addItem("")
self.comboBox_type.setItemText(1, "dot")
self.comboBox_type.addItem("")
self.comboBox_type.setItemText(2, "link")
self.checkBox_hide = QtWidgets.QCheckBox()
self.checkBox_hide.setGeometry(QtCore.QRect(70, 100, 51, 23))
self.checkBox_hide.setText("hide")
self.checkBox_hide.setIconSize(QtCore.QSize(16, 16))
self.checkBox_hide.setTristate(False)
self.checkBox_hide.setObjectName("checkBox_hide")
self.pushButton = QtWidgets.QPushButton()
self.pushButton.setGeometry(QtCore.QRect(10, 130, 111, 25))
self.pushButton.setText("create")
self.pushButton.setObjectName("pushButton")
self.label_icon = QtWidgets.QLabel()
self.label_icon.setGeometry(QtCore.QRect(15, 10, 100, 80))
self.label_icon.setText("")
self.label_icon.setObjectName("label_icon")
self.label_nodename = QtWidgets.QLabel()
self.label_nodename.setGeometry(QtCore.QRect(15, 10, 100, 80))
font = QtGui.QFont()
font.setWeight(75)
font.setBold(True)
self.label_nodename.setFont(font)
self.label_nodename.setText(nodename)
self.label_nodename.setAlignment(QtCore.Qt.AlignCenter)
self.label_nodename.setObjectName("label_nodename")
QtCore.QMetaObject.connectSlotsByName(self)下面是我的主应用程序中的代码，它们作为项目添加到我的listwidget中：
class Connecthor(QtWidgets.QMainWindow, Ui_MainWindow):
#constructor
def __init__(self, parent=None):
super(Connecthor, self).__init__(parent)
self.setupUi(self)
self.setFixedSize(self.size())
#ADDING TEST WIDGETS
for i in range(5):
self.createNewLink("test","")
def createNewLink(self, nodename, nodeclass):
item = QtWidgets.QListWidgetItem(self.listWidget_links)
item_widget = NodeLinkItemWidgetUI.Ui_Form(nodename=nodename, nodeclass=nodeclass)
#size hint doesn't return the correnct widget size so I did set it manually
# print item_widget.sizeHint()
# item.setSizeHint(item_widget.sizeHint())
item.setSizeHint(QtCore.QSize(130, 160))
self.listWidget_links.addItem(item)
self.listWidget_links.setItemWidget(item, item_widget)页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
