I'm new to pyqt and I'm having a question about QComboBox. I have
one on a form that I would like to populate with data from a
db-table. The table is very simple, it has only two columns, an id
and a description. I would like to add the descriptions as items to
the combobox with the id as index. (Something like:
self.cmbSearch.insertItem(description, id)). But I'm getting 'index
out of range' errors. Could this be because the indexes need to be
in consecutive order (and the series of id's isn't) ? I can't find
info on this in the pyqt-documentation...
I'm new myself, but I've done a few small apps since starting. The
TrollTech docs are very useful (http://doc.trolltech.com/), but I
didn't find an easy way to do what you're after (having a Combo Box
with a "value" for each entry, a la HTML forms).
The way I got around it was to separately store a mapping (or what's
the python term? Dictionary or something?) of either the labels, or
the combo box index, to the values you're after. So, when you populate
the entries in the field, also populate a mapping. Then, to get the
value, you use the text or index to look up the mapping to get the value.
The index value of the combo box is solely a numeric item number for
the items in the list (AFAIK).
Tnx for your response Trevor! I was already thinking in the same
direction... Seems a good way to do this.
Greetings,
Tom
