我正在使用以下代码创建QListView和QStandardItemModel:
self.listView = QtWidgets.QListView(self.groupBox2)
self.listView.setGeometry(QtCore.QRect(200, 20, 400, 220))
self.entry = QtGui.QStandardItemModel()
我正在使用类似于以下内容的循环添加项目:
self.item1 = QtGui.QStandardItem("Itemname1")
self.entry.appendRow(self.item1)
self.item2 = QtGui.QStandardItem("Itemname2")
self.entry.appendRow(self.item2)
我如何将这些项目分配给一个列表,知道列表中的0代表“ Itemname1”,1代表“ Itemname2”等?
另外,如何将QListView中的项目设置为选中状态?
setSelected()
对于QStandardItemModel似乎不存在 最佳答案
尝试一下:
import sys
from PyQt5 import QtWidgets, QtGui, QtCore
from PyQt5.QtGui import QBrush, QColor
class Widget(QtWidgets.QWidget):
def __init__(self):
super().__init__()
lay = QtWidgets.QVBoxLayout(self)
self.listView = QtWidgets.QListView()
self.label = QtWidgets.QLabel("Please Select item in the QListView")
lay.addWidget(self.listView)
lay.addWidget(self.label)
self.entry = QtGui.QStandardItemModel()
self.listView.setModel(self.entry)
self.listView.clicked[QtCore.QModelIndex].connect(self.on_clicked)
# When you receive the signal, you call QtGui.QStandardItemModel.itemFromIndex()
# on the given model index to get a pointer to the item
for text in ["Itemname1", "Itemname2", "Itemname3", "Itemname4"]:
it = QtGui.QStandardItem(text)
self.entry.appendRow(it)
self.itemOld = QtGui.QStandardItem("text")
def on_clicked(self, index):
item = self.entry.itemFromIndex(index)
self.label.setText("on_clicked: itemIndex=`{}`, itemText=`{}`"
"".format(item.index().row(), item.text()))
item.setForeground(QBrush(QColor(255, 0, 0)))
self.itemOld.setForeground(QBrush(QColor(0, 0, 0)))
self.itemOld = item
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
w = Widget()
w.show()
sys.exit(app.exec_())
