[model/view] custom QTimeEdit as an editor in a custom QItemDelegate
Message 1 in thread
Hi all,
in a subclass of QItemDelegate, I create my own QTimeEdit to edit some data.
I select carefully selecte the appropriate column in the QTimeEdit.
In MyDelegate::createEditor, the appropriate column is selected (minutes,
indeed).
In MyDelegate::setEditorData, the selected column is still correct.
Unfortunately, when the editor is displayed, the column selected has been
reset by Qt (the Hour column selected instead of the Minute column).
I've traced all the calls in MyDelegate.
Indeed, apparently, the selected column in QTimeEdit is reset by Qt between
MyDelegate::setEditorData
and the first call to
MyDelegate::paint (indeed, the painted column is NOT the edited column...)
Does anyone would know where Qt resets the selected column ?
Is it in QTImeEdit (on first show event, or anything else) ?
Or in QItemDelegate ?
Thanks in advance,
Best,
Nicolas

Message 2 in thread
I have a custom delegate and model for a table and am seeing a similar
thing (I'm assuming that you mean the heading is "bold" when editing a
cell in the column). I'd be interested if anyone knows where to look
(perhaps somewhere in the view?)
Sorry I don't have an answer for you, but am seeking one myself.
