runtime

Christos,
thanks ... works in the same way and there's no need for an own class, I
just have a problem with the rownumber.
If users add more than one line, there will exist 2 or more Comboboxes.
Each of them will return the right index, but so far I could not find a
way to get the right row, because the self.tableWidgetX.currentRow()
returns the last row where a text-cell was entered. This means row is -1
when nobody clicked somewhere on the grid, and if you enter row 2, and
then change the combobox in row 5, self.tableWidgetX.currentRow() will
return 2!
As the row-number in Serges solution is passed plain this is also not a
100% solution as the row-sorting could be changed (user sorts data by
clicking on headers, or rows are (re)moved/added by code). But if I
prevent this at last the row-number should be correct.
For short, the way I've tested your solution:
from PyQt5.QtWidgets import QComboBox
@pyqtSlot()
def on_pushButton_add_row_to_tableWidgetX_clicked(self):
tWid=getattr(self, "tableWidgetX")
tWid.setRowCount(tWid.rowCount()+1)
combo = QComboBox()
combo.setSizeAdjustPolicy(QComboBox.AdjustToContents)
combo.addItems(["A","B","C"])
tWid.setCellWidget(tWid.rowCount()-1, 3, combo) # ComboBox
goes to last row, column Nr 3
tWid.setColumnWidth(3, combo.size().width())
combo.currentIndexChanged.connect(self.on_spk_ver_rep_QComboBox_currentIndexChanged)
@pyqtSlot(int)
def on_spk_ver_rep_QComboBox_currentIndexChanged(self, index):
print(index, self.tableWidgetX.currentRow())

Dear George,
I think that you should create a slot for the specific QComboBox
object and not for the cell of the QTableWidget object.
For example, for a QComboBox created in the Ui_MainWindow.setupUI(),
the corresponding slot created in the MainWindow.setupUI() should have
the following form, for integer or string type index.
@pyqtSlot(int)
def on_spk_ver_rep_QComboBox_currentIndexChanged(self, index):
"""
Slot documentation goes here.
@param index DESCRIPTION
@type int
"""
# TODO: not implemented yet
raise NotImplementedError
@pyqtSlot(str)
def on_spk_ver_rep_QComboBox_currentIndexChanged(self, p0):
"""
Slot documentation goes here.
@param p0 DESCRIPTION
@type str
"""
# TODO: not implemented yet
raise NotImplementedError

Hi @all,
I've created a dialog-window with an QTableWidget. Users can add a
row
by using a pushbutton. In a cell of the new row appears a
QComboBox. How
can changes of this QComboBox trigger a function?
It's no problem for to text-only-cells (I can use:
@pyqtSlot(int, int)
def on_tableWidgetX_cellChanged(self, row, column):
print("cell changed: ", row, column)
which works as intended.)
Functions like
@pyqtSlot(QComboBox)
def on_tableWidgetX_itemChanged(self, item):
print("OK1")
@pyqtSlot(QComboBox)
def on_tableWidgetX_itemClicked(self, item):
print("Ok2")
never recieve a signal.
I think the QComboBox can not send a aignal. Originally the "Generate
Dialog Code..."-dialog suggests to pass a "QTableWidgetItem*" to the
pyqtSlot, but this Item is created during runtime, so it can not be
found in the Ui_Dialog...
Any suggestions?
george
