Errors in EventLogger. This eventlogger is designed on Qt5 but having these errors in QT 6.2

@Christian-Ehrlicher I have solved the problem of QTime with QElapsedTimer
But I can't find replacement of QPixmap. Please if you can find share.

@Aviral-0 From the link @Christian-Ehrlicher gave you:

QPixmap QPixmap::grabWidget(QObject *widget, const QRect &rectangle)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

Use QWidget::grab() instead.

So, what about using grab() instead of grabWidget()?

@jsulm Yeah I am trying it, and its throwing error saying
call to non static member function without an object argument
If you know what change its aking?

all to non static member function without an object argument

Because QWidget::grab() is not a static function. You have to call it on an object (mainWidget I would guess) - plain c++ stuff.

@jsulm I have done this, please suggest where I am wrong:

 if (this->screenshotsEnabled && eventType.compare("MouseMove") != 0)
  {
    QPixmap *gb;
    gb mainWidget->grab().toImage().save(screenshotDirName + "/" + QString::number(elapsedTime) + ".png", "PNG");
}

Its showing error, Please Help!

Hi,

You are missing an = sign.

You do realise that "showing error" gives no information to help you with ?

As @SGaist points out, you are missing a "=".

You are also not initialising your pointer (a C++ cardinal sin) but ultimately that's a moot point.
QWidget::grab() returns an actual QPixmap, not a pointer to one.
There is also no need to convert the QPixmap to a QImage in order to save it: QPixmap::save().

 if (this->screenshotsEnabled && eventType.compare("MouseMove") != 0)
 {
    QPixmap gb = mainWidget->grab();
    gb.save(screenshotDirName + "/" + QString::number(elapsedTime) + ".png", "PNG");\
    // Consider whether you need to check that the save was successful
}
