From QVariant to Integer and String
The user's entered value
can be both: a string or an integer.
QAbstractTableModel
's setData()
method always gets this value
as QtCore.QVariant
Question:
How to implement if/elif/else
inside of setData()
to distinguish if the received QVariant
is a string or an integer? (so a proper QVariant
conversion method (such as .toString() or toInt()) is used)
P.s. Interesting that an attempt to convert QVariant
toInt() results to a tuple such as: (0, False)
or (123, True)
python qt pyqt qtcore qvariant

You can check against the type:
if myVariant.type() == QVariant.Int:
value = myVariant.toInt()
elif myVariant.type() == QVariant.QString:
value = myVariant.toString()
Given that the form above is now obsolete, it is recommended to check it this way:
if myVariant.canConvert(QMetaType.Int):
value = myVariant.toInt()
elif myVariant.canConvert(QMetaType.QString)
value = myVariant.toString()
Thanks! Simple and it works! :)

I tried to edit the post but my modification would be less than 6 chars so I couldn't.QVariant.type
is actually a method, so the first example should beif myVariant.type() == QVariant.Int
instead ofif myVariant.type == QVariant.Int
