How to link 3 objects in QT to each other?

Question

Qt

I started to study QT, set myself a small task and immediately I can’t implement it. Question: how to make it so that when a button is pressed, the text written in a line and being processed by the algorithm is displayed in the text browser? I can't figure out how to implement this in terms of signals and slots. Help me please.

Answer 1

button -
line button - string field
browse - browser text

connect(button, SIGNAL(clicked()), this, SLOT(slotClicked())); // это устаревшая запись, используйте другую.

void slotClicked() {
    QString str = line->text();
    ///....
    browse->setText(str);
}
