<div dir="ltr"><div>There are different approaches, depending on your needs and the size of the table.<br></div>If the size is not very big, using QTableWidget is fine, and you can access the data as you wrote (it works, see below).<div>While this has the advantage of mixing different kinds of widgets independently (not row or column related), it also means that you should track every combo, and adding or removing cells and widgets might be a bit annoying for very large models.<br><div>The alternative is using a QStandardItemModel and set a custom item delegate (QItemDelegate or, better, QStyledItemDelegate) for the column or row you are interested into; if you want, you can set the default delegate for the whole table too. In this way the table only cares about its data (which is usually better) and you can set the combobox only when editing, through the createEditor method of the delegate.</div></div><div>There is also the possibility of using QAbstractItemDelegate.setIndexWidget(index, widget), which is very similar to the use of the QTableWidget, but is not very suited for interaction.</div><div><br></div><div>I tried to use cellWidget to get the value from the combo and it works without problems. Are you sure you implemented it in the right way?<br>Here's a simple example:</div><div><br></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div><div><font face="monospace, monospace">class Widget(QtWidgets.QWidget):</font></div></div><div><div><font face="monospace, monospace"> def __init__(self):</font></div></div><div><div><font face="monospace, monospace"> QtWidgets.QWidget.__init__(self)</font></div></div><div><div><font face="monospace, monospace"> l = QtWidgets.QGridLayout()</font></div></div><div><div><font face="monospace, monospace"> self.setLayout(l)</font></div></div><div><div><font face="monospace, monospace"> self.table = QtWidgets.QTableWidget(20, 1)</font></div></div><div><div><font face="monospace, monospace"> l.addWidget(self.table)</font></div></div><div><div><font face="monospace, monospace"> for r in range(10):</font></div></div><div><div><font face="monospace, monospace"> combo = QtWidgets.QComboBox()</font></div></div><div><div><font face="monospace, monospace"> combo.addItems([str(i) for i in range(50)])</font></div></div><div><div><font face="monospace, monospace"> self.table.setCellWidget(r, 0, combo)</font></div></div><div><div><font face="monospace, monospace"> self.btn = QtWidgets.QPushButton()</font></div></div><div><div><font face="monospace, monospace"> l.addWidget(self.btn)</font></div></div><div><div><font face="monospace, monospace"> self.btn.clicked.connect(self.printValue)</font></div></div><div><div><font face="monospace, monospace"><br></font></div></div><div><div><font face="monospace, monospace"> def printValue(self):</font></div></div><div><div><font face="monospace, monospace"> print(self.table.cellWidget(4, 0).currentText())</font></div></div></blockquote><div><br></div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">2018-05-27 18:04 GMT+02:00 Ke Gao <span dir="ltr"><<a href="mailto:ke.gao.ut@gmail.com" target="_blank">ke.gao.ut@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div>Hi,<br><br></div>I want to add a combobox into a a table, what is the best way, using tableview or tablewidget?
