在Qt里，在QTableView中嵌入QComboBox真的很方便，只要实现一个QItemDelegate就可以了；QComboBox要想实现自定义下拉框也很方便，只要调用setView即可。PyQt示例代码如下：
#!/usr/bin/env python #coding=utf-8 from PyQt4.QtGui import * from PyQt4.QtCore import * class DBComboBoxDelegate(QItemDelegate): def __init__(self, comboModel, parent=None): QItemDelegate.__init__(self, parent) self.comboModel = comboModel def __createComboView(self, parent): view = QTableView(parent) view.setModel(self.comboModel) view.setAutoScroll(False) view.setHorizontalScrollBarPolicy(Qt.ScrollBarAsNeeded) view.setSelectionMode(QAbstractItemView.SingleSelection) view.setSelectionBehavior(QAbstractItemView.SelectRows) view.resizeColumnsToContents() view.resizeRowsToContents() view.setMinimumWidth(view.horizontalHeader().length()) return view def createEditor(self, parent, option, index): combo = QComboBox(parent) #!! The important part: First set the model, then the view on the combo box combo.setModel(self.comboModel) #combo.setModelColumn(1) combo.setView(self.__createComboView(parent)) return combo def setEditorData(self, editor, index): value = index.model().data(index, Qt.EditRole).toString() editor.setCurrentIndex(editor.findText(value)) def setModelData(self, editor, model, index): if editor.currentIndex() >= 0: realidx = editor.model().index(editor.currentIndex(), 0) #确保取第一列的值 value = editor.model().data(realidx) model.setData(index, value, Qt.EditRole) ############################################################################### if __name__ == '__main__': import sys app = QApplication(sys.argv) table = QTableView() comboModel = QStandardItemModel(4, 2, table) comboModel.setHorizontalHeaderLabels(['Name', 'Description']) comboModel.setData(comboModel.index(0, 0, QModelIndex()), QVariant(u'树袋熊')) comboModel.setData(comboModel.index(0, 1, QModelIndex()), QVariant(u'生活在树上的熊')) comboModel.setData(comboModel.index(1, 0, QModelIndex()), QVariant(u'松鼠')) comboModel.setData(comboModel.index(1, 1, QModelIndex()), QVariant(u'可爱的松树精灵')) comboModel.setData(comboModel.index(2, 0, QModelIndex()), QVariant(u'大眼猴')) comboModel.setData(comboModel.index(2, 1, QModelIndex()), QVariant(u'这猴眼睛真大')) comboModel.setData(comboModel.index(3, 0, QModelIndex()), QVariant(u'猫头鹰')) comboModel.setData(comboModel.index(3, 1, QModelIndex()), QVariant(u'夜的精灵正站在树枝上')) model = QStandardItemModel(2, 3, table) model.setHorizontalHeaderLabels(['Name', 'Height', 'Weight']) model.setData(model.index(0, 0, QModelIndex()), QVariant(u'松鼠')) model.setData(model.index(0, 1, QModelIndex()), QVariant(u'80cm')) model.setData(model.index(0, 2, QModelIndex()), QVariant(u'12Kg')) table.setModel(model) table.setItemDelegateForColumn(0, DBComboBoxDelegate(comboModel, table)) table.horizontalHeader().setStretchLastSection(True) table.setGeometry(80, 20, 400, 300) table.setWindowTitle('Grid + Combo Testing') table.show() sys.exit(app.exec_())
