QWidget *myWidget = new QWidget(); myWidget->setObjectName("myWidget");
QObjectList widgets = ui->centralWidget->children(); for (int i = 0; i < widgets.size(); i++) { QWidget *widget = qobject_castThis code gets a list of all child objects of the "centralWidget" object in the user interface. It then loops through the list and checks if each object is a QWidget with an objectName of "myWidget". If it finds a match, it can perform some action on the widget. These examples use the Qt library, which is a popular package for creating cross-platform GUI applications in C++.(widgets.at(i)); if (widget && widget->objectName() == "myWidget") { // do something with widget } }
