Qt: "Expanding" doesn't work inside a layout -


my purpose create scrollable control qvboxlayout inside of has various controls (say buttons) on it. control put on *.ui form. in constructor control write following code:

    myscrollarea::myscrollarea(qwidget *parent) :         qscrollarea(parent)     {         // create scrollable container          this->container = new qwidget();  // container widget member         this->container->setsizepolicy(qsizepolicy::expanding, qsizepolicy::expanding);         this->container->setcontentsmargins(qmargins(0,0,0,0));          this->content = new qvboxlayout(); // layout member         this->content->setmargin(0);         this->content->setspacing(0);          (int i=0; i<100; i++)         {             qpushbutton * widget = new qpushbutton();             widget->settext("button");             widget->setsizepolicy(qsizepolicy::expanding, qsizepolicy::fixed);             this->content->addwidget(widget);         }          this->container->setlayout(this->content);         this->content->layout();          this->setwidget(this->container);    }

my problem: buttons have fixed size , do not expand horizontally. have fixed size. i'd them expand horizontally fill row they're in. how can them expanding horizontally across parent container?

try calling this->setwidgetresizable(true);
