put two widgets to the two sides of a tab or window [复制链接]

 
QWidget * widget = new QWidget(  parent  );
  QRadioButton * button  = new QRadioButton( tr( "Calculation" ), widget );
  QCheckBox * checkbox = new QCheckBox( tr( "Do something" ), widget );
  checkbox->setChecked( false );
   
  QHBoxLayout * hlayout = new QHBoxLayout();   
    hlayout->addWidget( button );
    hlayout->addWidget( checkbox );
    hlayout->insertStretch( 1, 5 ); //<=====stretch helps
    widget->setLayout( hlayout );

应该qt本身不能，做不到layoutdir 只有两种righttoleft ,leftoright

I do not know what you mean 应该qt本身不能. The code above is used in my package and works fine.

try一下你的例子，再问一下？在designer 能做到吗？

你的例子正常，问下如果是QTabWidget 能做到吗?
