why toolbars layout differently when state restored and when i dont use state restore function?

[jacek]

Maybe because you save the state in destructor? It might be too late. What does s.value("MainWindowState").isValid() return?

[EnErGy[CSDX]]

it isn`t too late.
issue is that if toolbar created after state restore toolbar placed at end of line with minimum size.

Do you run example?

This seems to work:

Window(void):QMainWindow()
  {
      t=new QToolBar("Toolbar1",this);
      t->setObjectName( "aaa" );
      t->addAction(new QAction("Act1",this));
      t->addAction(new QAction("Act2",this));
      t->addAction(new QAction("Act3",this));
      addToolBar(t);
 
      t=new QToolBar("Toolbar2",this);
      t->setObjectName( "bbb" );
      t->addAction(new QAction("Act1",this));
      t->addAction(new QAction("Act2",this));
      t->addAction(new QAction("Act3",this));
      addToolBar(t);
 
      QSettings s("Trolltech","TestAPP");
      restoreState(s.value("MainWindowState").toByteArray());
}

Window(void):QMainWindow()
  {
      t=new QToolBar("Toolbar1",this);
      t->setObjectName( "aaa" );
      t->addAction(new QAction("Act1",this));
      t->addAction(new QAction("Act2",this));
      t->addAction(new QAction("Act3",this));
      addToolBar(t);

      t=new QToolBar("Toolbar2",this);
      t->setObjectName( "bbb" );
      t->addAction(new QAction("Act1",this));
      t->addAction(new QAction("Act2",this));
      t->addAction(new QAction("Act3",this));
      addToolBar(t);

      QSettings s("Trolltech","TestAPP");
      restoreState(s.value("MainWindowState").toByteArray());
}
