QLabel clearing pixmap when QFileDialog is selected.

[Sriu1]

I have a label and a pushButton which sets image to the label on clicked.If label initially has a image set and If the button is clicked the label gets cleared even before selecting image from the FileDialog.

Below is the code

void MainWindow::on_backgroundImageBrowse_clicked()
{

    qstrFileName = QFileDialog::getOpenFileName (
            this,
            "file",
            "~/",
            tr ("Image (*.bmp *.jpg );;All files (*.*)")
        );
    m_ZoneManager->GUI_generalstruct->generalBackgroundImage = qstrFileName;
    QPixmap pix (m_ZoneManager->GUI_generalstruct->generalBackgroundImage);
    ui->label->setStyleSheet ("border-image:url(m_ZoneManager->GUI_generalstruct->generalBackgroundImage);");
    int w = 1280;
    int h = 720;
    ui->label->setPixmap (pix.scaled (w, h)); //,Qt::KeepAspectRatio

}

Even If cancel is clicked in the fileDialog the label is getting cleared.Please suggest

@Sriu1 Please read http://doc.qt.io/qt-5/qfiledialog.html#getOpenFileName
"If the user presses Cancel, it returns a null string."
I don't see you checking whether qstrFileName is a null string or not.
Also this line does not make any sence:

ui->label->setStyleSheet ("border-image:url(m_ZoneManager->GUI_generalstruct->generalBackgroundImage);");
