点击QTableView
" Item_B_001 "打印出行号# 0 。
但是在源模型self.items
中,此项目对应于数字#3。如何获得"真实"源模型的项目行号 - 它真正对应的数字?

class Model(QAbstractTableModel):
def __init__(self, parent=None, *args):
QAbstractTableModel.__init__(self, parent, *args)
self.items = ['Item_A_001','Item_A_002','Item_B_001','Item_B_002']
def rowCount(self, parent=QModelIndex()):
return len(self.items)
def columnCount(self, parent=QModelIndex()):
return 1
def data(self, index, role):
if not index.isValid(): return QVariant()
elif role != Qt.DisplayRole:
return QVariant()
row=index.row()
if row<len(self.items):
return QVariant(self.items[row])
else:
return QVariant()
class Proxy(QSortFilterProxyModel):
def __init__(self):
super(Proxy, self).__init__()
def filterAcceptsRow(self, row, parent):
if '_B_' in self.sourceModel().data(self.sourceModel().index(row, 0), Qt.DisplayRole).toPyObject():
return True
return False
class MyWindow(QWidget):
def __init__(self, *args):
QWidget.__init__(self, *args)
tableModel=Model(self)
proxyModel=Proxy()
proxyModel.setSourceModel(tableModel)
self.tableview=QTableView(self)
self.tableview.setModel(proxyModel)
self.tableview.clicked.connect(self.viewClicked)
self.tableview.horizontalHeader().setStretchLastSection(True)
layout = QVBoxLayout(self)
layout.addWidget(self.tableview)
self.setLayout(layout)
def viewClicked(self, indexClicked):
print 'index of proxy row', indexClicked.row()
if __name__ == "__main__":
app = QApplication(sys.argv)
w = MyWindow()
w.show()
sys.exit(app.exec_())
答案 0 :(得分:2)
我认为你可以使用QAbstractProxyModel::mapToSource()
函数返回源模型中与代理模型中的索引相对应的模型索引。即(不确定Python语法):
def viewClicked(self, indexClicked):
print 'index of proxy row', self.proxyModel.mapToSource(indexClicked).row()
