Answer 1

Implemented the above using below code
bool MainWindow::eventFilter(QObject *obj, QEvent *event)
{
if(obj == ui->mGbPowerModes)
{
if(event->type() == QEvent::KeyPress)
{
QKeyEvent* keyEvent = static_cast<QKeyEvent*>(event);
if(keyEvent->key() == Qt::Key_Up)
{
if(ui->mBtnOff->isChecked())
{
on_mBtnPropulsion_clicked();
ui->mBtnPropulsion->setFocus();
ui->mBtnPropulsion->setChecked(true);
}
return true;
}
else if(keyEvent->key() == Qt::Key_Down)
{
if(ui->mBtnPropulsion->isChecked())
{
on_mBtnOff_clicked();
ui->mBtnOff->setFocus();
ui->mBtnOff->setChecked(true);
}
return true;
}
}
return false;
}
return MainWindow::eventFilter(obj, event);
}

here is a minimal Example on how you can specify navigation with arrowkeys like you want it, you can use the "KeyNavigation.X" property to tell the next focus item when you press the defined key. - hope this helps:
Column {
Label {
text: qsTr("Radio:")
}
RadioButton {
id: test1
checked: true
text: qsTr("DAB")
KeyNavigation.down: test2
KeyNavigation.up: test3
}
RadioButton {
id:test2
text: qsTr("FM")
KeyNavigation.down: test3
KeyNavigation.up: test1
}
RadioButton {
id:test3
text: qsTr("AM")
KeyNavigation.down: test1
KeyNavigation.up: test2
}
}
