Question

Qt

Maine has this code

    QWidget wgt;

QString str;

QLineEdit* line_edit_1  = new QLineEdit;
QPushButton* push_but = new QPushButton;

QHBoxLayout* phbxLayout = new QHBoxLayout;
     phbxLayout->setContentsMargins(10, 10, 10, 10);
     phbxLayout->setSpacing(20);

     phbxLayout->addWidget(line_edit_1);
     wgt.setLayout(phbxLayout);
     wgt.show();

Answer 1

You need to create your own slot in which to connect the click, and get the text from the button there.

Answer 2

Read any book on Qt. I understand that it seems like a long time, and there are a lot of beeches, but you will save yourself a lot of time and will not get stuck on such elementary questions.
