rexha52

hey guys, pls help me
Im have QWidget class Section
and button for add Section:

void MainWindow::on_button_AddZone_clicked()
{
    new_zone_name="Place #";
    QString name=new_zone_name+QString::number(++ui::Section::zone_count);
    section = new ui::Section(name,300, ui->centralWidget);
    ui->centralWidget->layout()->addWidget(section);
    auto* anyLayout = new QVBoxLayout();
    anyLayout->addWidget(new QLabel("Some Text in Section", section));
    anyLayout->addWidget(new QTableView(section));
    section->setContentLayout(*anyLayout);
}

and Section have some function

public slots:
       void toggle(bool collapsed);

how i can call this func for ALL created by button QWidget from MainWindwow?
how i can call this func for definetely QWidget? (I can use some ID and etc???)

Connect all your Section objects to receive a toogle signal emitted by the MainWindow.

Overall your code is strange ...

If you mean call it once at creation time you can call a public slot directly: section->toggle(true);. If you mean in response to later signal do connect() as @mpergand says.

how i can call this func for definetely QWidget? (I can use some ID and etc???)

I cannot understand this sentence.

when im click ADD BUTTON it create a widget from class Section. Every Section have some other widget(table, button, lavel etc)
when im created 5 Sections, how i can read some values or call some function from a certain Section, for example for QLabel in second Section? or in last created Section?

Please show how you're creating those Section instances

As @jsulm has responded. If you have a "list" of things, store & access them in an array/list. Nothing more to say.
