[Solved] How to iterate all widgets in a QWidget window?

[stuartx]

Hi, I created an UI form based on QWidget, then added some widgets in the form including some customized widgets. In the constructor of the UI class, I want to iterate through all the widgets and process on my customized widgets. I use the Focus Chain to loop through all widgets in the UI form. This is what I do:

@MyForm::MyForm(QWidget *parent) :
QWidget(parent),
ui(new Ui::MyForm)
{
ui->setupUi(this);

QWidget *w = this;
while (w)
{
    MyCustomeWidget *d = qobject_cast<MyCustomeWidget *>(w);
    if (d) {
          //process on d
    }
    w = w->nextInFocusChain();
    if (w == this) break;
}

}@

I am wondering if this is the right way to do this or if there is better way to perform the iteration?

Thanks.

this->findChild<MyCustomWidget*>();

Thanks. I think I should do:
@QList<MyCustomeWidget*> list = this->findChildren<MyCustomeWidget *>();
foreach(MyCusteWidget *w, list) {
//process w
}@

Any objection/suggestion?

Not at all, that was an example. I didn't know how many of those you had so I settled with the easier variant to write down, thinking you would adapt it appropriately (and you did ;) ).
