QList with unknown number of items

[jipe3001]

I am using a Qlist declared as follows:

QList <QWidget *> List_a;

Of course I can add items with List_a.append(W1);

assuming W1 is a Widget declared before

but my concern is that I do not know how many Widget I will have to add
to List_a (depending of a file content read before).

How could I create these widgets in a loop and then add to the Qlist ?

Hi
You mean new them ?
for (int c=0; c < 100; c++) {
List_a.append( new QPushButton );
}
would add 100 push buttons.

However, what will you you use the widgets for ?
If you assign them a parent, and delete parent, then it will
delete the Widgets too and list would contain invalid pointers.

So what are you planning to do with these widgets ?
