How to get Qwidget that added to Vertical lay out



  • Hi, i add Some Widget to a Vertical lay out. now i want retrieve them like this:

    @
    for(int i =0; i < ui->verticalLayout_6->children().count(); i++)
    {
    QWidget* Widget = dynamic_cast<QWidget*>(ui->verticalLayout_6->children().at(i));
    if(Widget != NULL)
    {
    for(int j = 0; j < Widget->children().count(); j++)
    {
    QLineEdit TempLine = dynamic_cast<QLineEdit>(Widget->children().at(j));
    if(TempLine != NULL)
    {
    TempLine->setText("peida kardam :D :P");
    }
    }

            }
    
    
        }
    

    @
    but ui->verticalLayout_6->children().count(); returns 0. how can i retrieve them?
    any idea?
    another question is that how can change space between Pushbuttons that added to Vertical lay out. I use
    @
    ui->verticalLayout->setSpacing(1);
    @
    but i doesn't work.
    any idea?

    Hi,

    Since it looks like you have an UI file... Do you add your widgets programmatically ?
