Pyqt5 help!!

[Dexter99]

Hi I have a program that should add about 40 labels(one at a time) when a button is clicked. Now I don't want to be an idiot and make blank labels and then change the text if those. Is there a more efficient way of displaying the labels. Thank you.

@Dexter99 You can create widgets (like labels) dynamically and show them:

void MainWindow::on_button_clicked()
{
    QLabel *label = new QLabel(this, "Some text");
    // Put your label into layout or position it manually
    label->show();
}

Not that it matters, but for the record do you have to show() it after adding? I could swear I add dynamic labels all the time without calling show()...

Oooo sorry that was idiotic.

If not added to a layout applied on a visible widget, then yes you have to call show.

Ah, yes, I do mean adding to already visible widget parent/layout, so that's why I don't need to.

So, I'm not criticising @jsulm's code, but where he has added new QLabel(this, "Some text"); the this is the QMainWindow, which will be shown, so he didn't need to put in the label->show();, right?
