problem with a list of pointers

[lyuts]

What about foreach ?

foreach (QWidget *widget, list) {
    ...
}

foreach (QWidget *widget, list) {
    ...
}

To copy to clipboard, switch view to plain text mode

but is i do with a foreach,i have the same problem.
foreach (QWidget *widget, list) {
v.at(0)->getScreenDirectionlist(&list);
}

What I need is to link my pointers of the widget that I have got, with the whole list in a for. this1->getScreenDirectionlist(&list); but with a for to make shorter the code.

No, you have to do this

foreach (QWidget *widget, yourWidgetsList) {
    widget->getScreenDirectionlist(some_other_list);
}

foreach (QWidget *widget, yourWidgetsList) {
    widget->getScreenDirectionlist(some_other_list);
}

To copy to clipboard, switch view to plain text mode 

There is a little bit confusion about v and list. What are they for?
