Screenshot with QT

firsnur96

Im using the code below for taking screenshot of my charts.
But i dont want to open a file dialog.
I want to save them with a giving format. In every new picture it will save it the date and time.
I dont want to give a name.
How can i do it without file dialog?

```
QRect crop_rect(int x, int y, int w, int h);
QPixmap desk = qApp->screens().at(0)->grabWindow(
    QDesktopWidget().winId());

   QString format = "jpg";
   QString initialPath = tr("Screenshots") + tr("/Image.") +
           QDateTime::currentDateTime().toString("dd.MM.yyyy" "hh.mm.ss.") + format;

   QString fileName = QFileDialog::getSaveFileName(this, tr("Save As"),
                              initialPath,
                              tr("%1 Files (*.%2);;All Files (*)")
                              .arg(format.toUpper())
                              .arg(format));
   if (!fileName.isEmpty())
       desk.save(fileName, format.toLatin1().constData());

Then don't open a dialog, what is the problem?
Construct the file name as you need and use it...

Are you asking me how to add a button?
Can you please explain what you want to do?
Should there be a button to select folder where user can store screen-shots?
What is the problem with that? Add a button, connect its clicked signal to a slot where you use https://doc.qt.io/qt-5/qfiledialog.html#getExistingDirectory to let the user select a folder, really nothing special...
