<![CDATA[How QPushButton checked show only border-bottom ?]]>The style border-bottom do not work.
And can set style to QButtonGroup ?

setStyleSheet("QPushButton { font-size:20px; }"
              "QPushButton:checked { border-bottom:1px solid rgb(0,131,221); color:rgb(0,131,221); font-size:20px;}");

And use QTabWidget instead of QButtonGroup is much more better here.

ui->pushButton_2->setCheckable(true);
    ui->pushButton_2->setStyleSheet("QPushButton { font-size:20px; }"
                                    "QPushButton:checked { border:none;border-bottom:1px solid rgb(0,131,221); color:rgb(0,131,221); font-size:20px;}");
}
