QToolButton* myButton = new QToolButton(this); // create a new QToolButton object myButton->setText("Click me!"); // set the text of the button
QToolButton myButton; // create a QToolButton object myButton.setText(tr("Open")); // set the text of the button using the tr() functionIn this example, a QToolButton object is created and the text of the button is set to "Open" using the tr() function. The tr() function can be used to translate the text of the button to different languages. The package library used for Qt development in C++ is likely the Qt Core library.
