从 Pyqt5 中的可检查组合框中获取已检查的文本
get checked text from checkable combobox in Pyqt5
我正在尝试从使用 pyqt5 中的复选框创建的自定义组合框中收集选中项目的文本。
这是我的可行代码段，它没有按照我的预期打印选定的文本：
from PyQt5 import QtCore, QtGui, QtWidgets
import sys
class CheckableComboBox(QtWidgets.QComboBox):
def __init__(self, parent = None):
super(CheckableComboBox, self).__init__(parent)
self.view().pressed.connect(self.handleItemPressed)
self.setModel(QtGui.QStandardItemModel(self))
def handleItemPressed(self, index):
item = self.model().itemFromIndex(index)
if item.checkState() == QtCore.Qt.Checked:
item.setCheckState(QtCore.Qt.Unchecked)
else:
item.setCheckState(QtCore.Qt.Checked)
def checkedItems(self):
checkedItems = []
for index in range(self.count()):
item = self.item(index)
if item.checkState() == Qt.Checked:
checkedItems.append(item)
return checkedItems
class Ui_dialogCreateBatch(object):
def setupUi(self, dialogCreateBatch):
dialogCreateBatch.resize(400, 338)
dialogCreateBatch.setMouseTracking(True)
self.gridLayoutWidget = QtWidgets.QWidget(dialogCreateBatch)
self.gridLayoutWidget.setGeometry(QtCore.QRect(10, 10, 360, 115))
self.gridLayoutWidget.setObjectName("gridLayoutWidget")
self.gridLayout = QtWidgets.QGridLayout(self.gridLayoutWidget)
self.gridLayout.setContentsMargins(0, 0, 0, 0)
self.gridLayout.setObjectName("gridLayout")
self.cboItemList = CheckableComboBox(self.gridLayoutWidget)
self.cboItemList.setObjectName("cboItemList")
self.gridLayout.addWidget(self.cboItemList, 0, 0, 1, 1)
data = ('item1', 'item2', 'item3')
for index, element in enumerate(data):
self.cboItemList.addItem(element)
item = self.cboItemList.model().item(index, 0)
item.setCheckState(QtCore.Qt.Unchecked)
self.buttonBox = QtWidgets.QDialogButtonBox(dialogCreateBatch)
self.buttonBox.setGeometry(QtCore.QRect(100, 300, 156, 23))
self.buttonBox.setOrientation(QtCore.Qt.Horizontal)
self.buttonBox.setStandardButtons(QtWidgets.QDialogButtonBox.Cancel|QtWidgets.QDialogButtonBox.Ok)
self.buttonBox.setObjectName("buttonBox")
self.retranslateUi(dialogCreateBatch)
self.buttonBox.accepted.connect(self.accept)
self.buttonBox.rejected.connect(dialogCreateBatch.reject)
QtCore.QMetaObject.connectSlotsByName(dialogCreateBatch)
def retranslateUi(self, dialogCreateBatch):
_translate = QtCore.QCoreApplication.translate
dialogCreateBatch.setWindowTitle(_translate("dialogCreateBatch", "Create Item Batch"))
def accept(self):
selectedItems = self.cboItemList.checkedItems()
print(selectedItems)
dialogCreateBatch.close
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
dialogCreateBatch = QtWidgets.QDialog()
ui = Ui_dialogCreateBatch()
ui.setupUi(dialogCreateBatch)
dialogCreateBatch.show()
sys.exit(app.exec_())
在上面的代码中，我添加了用于记录返回数据的打印行。但我没有收到从这里返回的任何数据

在我的例子中，当我执行你的代码时，我看不到 QCheckBox，解决方案是建立一个 QListView 到 QComboBox 的 view()。
我看到的最大错误是在下面的表达式中 self.cboMulSup.checkedItems() 您试图访问 cboMulSup 但您从未定义它。
另一方面，不建议修改由 Qt Designer、PyQt 生成的代码，我建议创建另一个 class 从适当的小部件继承并使用 class Ui_xxx.
