/* the line wo i add .. */
class ItemLine : public QWidget


void Compose_Fak::RepainterWindowNow()
{
retranslateUi(this);
updateGeometry();
}

if i repaint widget so ...


void Compose_Fak::RepainterWindowNow()
{
int xh = height();
int xw = width();
resize(xw + 5,xh);
resize(xw,xh);
}

works ok....

but exist other solution?

When do you call that Compose_Fak::RepainterWindowNow() method? Maybe you block the event loop somewhere?

is possibel... is on same time...


connect( aggiungilineax, SIGNAL( clicked() ),this, SLOT( AppendLine()));
connect( aggiungilineax, SIGNAL( clicked() ),this, SLOT( RepainterWindowNow()));

i test on emit at end of RepainterWindowNow....

connect( aggiungilineax, SIGNAL( clicked() ),this, SLOT( RepainterWindowNow()));
When you trigger that slot using clicked() signal, then it means that updateGeometry() doesn't work for some other reason.

Why do you want to invoke it anyway?

void Compose_Fak::RepainterWindowNow()
{
int xh = height(); /* incomming emit ReloadPageFull() */
int xw = width();
resize(xw + 10,xh);
resize(xw,xh);
}

void Compose_Fak::AppendLine()
{
int sumflow = flow->count();
if ( sumflow < 9) {
summlinerfak++;
fiocco = new ItemLine(piano_centrale);
fiocco->setNumerate(summlinerfak);
fiocco->setTitle("Testo di descrizione");
fiocco->setQuant(2.5);
fiocco->setUnitprice(1.16);
flow->addWidget(fiocco);
/*QSize actualf = flow->sizeHint();
int hsww = actualf.height();
int wsww = actualf.width();
qDebug() << "### misura .. alto=" << hsww << " largo=" << wsww; */
lines.append( fiocco ); /* QList<ItemLine *> lines; */
} else {
aggiungilineax->setDisabled (true); /* disable button */
}
emit ReloadPageFull();
}

I had the same problem and "adjustSize()" on the parent widget did the trick (Qt4.8). (I know this thread is really old, but perhaps it helps someone.)
