Qt screenshot without start menu

ivanicy

Hello!

I am trying to get a screenshot of my application, but I don't want the start menu. Do you know how to get this screenshot without the start menu?

Here is my code:

QScreen *screen = QGuiApplication::primaryScreen();
        if (const QWindow *window = windowHandle())
            screen = window->screen();

        if (!screen) {
            return;
        }

        QPixmap originalPixmap = screen->grabWindow(0);

        QApplication::clipboard()->setPixmap(originalPixmap, QClipboard::Clipboard);

        QIcon icon2(":/ThermalAnalysis/Resources/ThermalAnalysis/screenshot.png");
        icon2.addPixmap(QPixmap(":/ThermalAnalysis/Resources/ThermalAnalysis/screenshot.png"));
        ui->screenshotButton->setIcon(icon2);

        QMessageBox::information(NULL, "Screenshot", "Screenshot sent to clipboard.", QMessageBox::Ok);

Thank you very much

Hi! You can use QWidget::grab() to grab only the widget you're interested in. E.g., to grab the central widget of a QMainWindow, use something like this:

void MainWindow::on_pushButton_clicked()
{
    auto const pm = centralWidget()->grab();
    pm.save("/path/to/file.png");
}
