Qt widget update

[deleted286]

Hi everone. Im trying to learn update issue of a widget. I want to ask something. What is the main difference between

QWidget::update();

and

 ui->groupBoxA->update();

I have some progress bar on my group box, ı want to update them. What if im updating the widget or updating the group box

@suslucoder

ui->groupBoxA->update(); calls update() on ui->groupBoxA. QWidget::update(); calls update() on whatever this is.

As we have said before, you should not find you are needing to use update() at all. You would be best served by producing a minimal example where you claim it is necessary, for people to look at....

@suslucoder The first one calls update() on the widget where it is called (same as this->update() except the widget overrides update() - in that case the base implementation is called).
Second one calls update() on groupBox.
This are C++ basics, nothing Qt related.
