<![CDATA[[SOLVED] QFileDialog::getSaveFileName - dialog is shown more then one time by call]]>I have next code:
@
QImage image(centralWidget_->rect().size(), QImage::Format_RGB32);
QPainter painter (&image);
painter.setRenderHint(QPainter::Antialiasing, true);
// Model is QGraphicsScene subclass
model_->clearSelection();
model_->render(&painter);

QString fileName = QFileDialog::getSaveFileName(NULL,
                                                tr("export as image:"),
                                                QDir::homePath(),
                                                QString(tr("Images: *.png *.jpg"))
                                                );

if (!fileName.isEmpty()) {
    image.save(fileName);
}

.......

When file's name has been chosen and i have pushed "save" button, this dialog appears again.
I use Qt 5.2 on debian linux.

You are right. Error was in connectModel() call which contain connect of MainWindow to it's own slot.

You have helped me, thank you very much!!!

@
private slots:
void loadFile();
........
private:
GraphModel *model_;
QGraphicsView *centralWidget_;
........
@

loadFile() has next code:
@
if (gl(fileName, model)) {
model->setParent(this);
delete model_;
model_ = model;
centralWidget_->setScene(model_);
connectModel();
......
@
Will after it model connected two time's? So how to correctly exchange my model?

Do you mean that my slot is called twice at time in this case?

This is SLOT of QMainWindow subclass.
