Answer 1

将分隔符项添加到右侧的水平布局中。

  QHBoxLayout * poHLayout = new QHBoxLayout;
  QPushButton * button = new QPushButton(cmd);
  // Spacer item
  QWidget * poSpacerItem = new QWidget(this);
  poSpacerItem->setSizePolicy(
                    QSizePolicy::Minimum,QSizePolicy::Maximum);
  // Add your button to the left side. (will align button to left)
  poHLayout->addWidget(button);      
  // Add spacer item
  poHLayout->addWidget(poSpacerItem);

  ui->scrollAreaWidgetContents->setLayout(poHLayout);
