int main(int argc, char *argv[]) {
        QApplication app(argc, argv);
        QWidget widget;
        auto *layout = new QBoxLayout(QBoxLayout::TopToBottom);
        widget.setLayout(layout);
        auto *msgWidget = new KMessageWidget();
        layout->addWidget(msgWidget);
        auto *btn = new QPushButton("btn");
        QObject::connect(btn, &QPushButton::clicked, [msgWidget]{
                msgWidget->setText("Abc" + msgWidget->text());
                msgWidget->animatedShow();
