QT setting suspension button

// If the size of the middle map chassis changes 
if(target==ui->widget_6&&event->type()==QEvent::Resize)
{
    auto resizeEvent=static_cast<QResizeEvent*>(event);
    // Set its map sub control to the same size 
    ui->widget_5->resize(resizeEvent->size());
}
// If the middle map chassis moves 
if(target==ui->widget_6&&event->type()==QEvent::Move)
{

// auto moveEvent=static_cast<QMoveEvent*>(event);
// The map sub control moves to the upper left corner ：
ui->widget_5->move(0,0);
// Move the alarm sub control to a position , Upper right corner
ui->alarmWidget->setFixedSize(100,100);
auto newPosition=QPoint(ui->widget_6->rect().width()-100,0);
ui->alarmWidget->move(newPosition);
// Lift to the top
ui->alarmWidget->raise();
}
Be careful , Coordinates of the control , Is the coordinate relative to its parent control .
