Add QPushButton to QTableWidget cell without using QTableWidget::setCellWidget

hbatalha

I need to add button to table cells and I have been using setCellWidget but it's a very slow operation and I need an alternative. I have been able to use a delegate but the problem is I haven't been able to add things like icons, stylesheet, connect signals the way I do with QPushButton.

Where is @VRonin just when you need him...? ;-)

hbatalha

@JonB Yeah I have been waiting on his answer here too.

JonB

@hbatalha
:) He is your man. He should be delighted to see you wanting to abandon setCellWidget() in favour of QStyledItemDelegate! But he is doubtless a busy man, he will be around soon....

hbatalha

@JonB yeah that's because of his warning that I noticed how slow 'setCellWidget()` was.

JonB

@hbatalha Hi will like you even more for that :)

So why not simply use a QStyledItemDelegate as already said. There are a lot of examples around how to use this...

hbatalha

@Christian-Ehrlicher I couldn't one example that handled signals mentioned in the OP.

Christian Ehrlicher

What's wrong with QAIM::activated() or clicked() ?

hbatalha

@Christian-Ehrlicher isn't that for the table cells instead of a widget like QPushButton?
I don't understand how that would work to solve the OP issue.

Sorry, I was away for a few days, answered on the previous thread

You are also wanted pretty desperately over at https://forum.qt.io/topic/131508/avoid-not-responding-when-adding-rows-to-qtablewidget/28, though I fear we may be fighting a losing battle, but it's funny/instructional to read....

Given the same OP and very similar problem I'd say https://forum.qt.io/post/687439 addresses it too

@VRonin
As he pleases, if he sees this (unless you want to refer him to that from there). He doesn't seem to want to change, and thinks other things are at fault too, so it's probably a losing battle...
