How to Print a Scrollable Application Window as a Full PDF in Qt

[Deep Patle]

I am working on a QML-based Qt application where I need to export the entire application window as a PDF. The window contains a scrollable area with dynamic content, but I’m facing challenges capturing all the content.

Previously, I attempted to use grabWindow(), but it only captures the visible portion of the window and not the entire scrollable content.

Here’s an overview of my implementation:

1. The main application is written in QML and has a ScrollView for displaying large content.

2. I am using a combination of QQuickWindow and C++ for generating the PDF using QPrinter and QPainter.

Could someone guide me on how to:

1. Capture the entire QML window, including all the content in the ScrollView, even the off-screen portions.

2. Save the captured content as a PDF.

Any code examples, suggestions, or references to similar use cases would be highly appreciated.
