How to set it up step-by-step. I am new to qt so stuck at various portions. Help me please.

Hi @FRAYOURSELF,

the library comes with a sample app which is used to showcase the features of the library. To try the sample app, open the 'pdf-viewer.pro' file with Qt creator.

To start from scratch, you need to create a qt quick project first:

Then follow those steps (as stated in the section of the README):

• include the library in your .pro:

QML_IMPORT_PATH += $$PWD/libs/qt-pdf-viewer-library/
QML_DESIGNER_IMPORT_PATH += $$PWD/libs/qt-pdf-viewer-library/
include($$PWD/libs/qt-pdf-viewer-library/qtpdfviewer.pri)

• initialize the library in your main.cpp just before QGuiApplication instantiation, and connect the aboutToQuit signal, emitted on app close, with the QtPdfViewerInitializer singleton deleteInstance method to allow the correct deletion of the initializer instance:

#include "it/ltdev/qt/cpp/components/qtpdfviewerinitializer.h"

int main(int argc, char *argv[])
{
  ...

  // Initialize QtPdfViewer library
  // To make the pdf module to function correctly across all platforms,
  // it is necessary to call QtPdfViewerInitializer::initialize()
  // before in Qt>= 5.15.0, or after in Qt<5.15.0, creating
  // the QGuiApplication instance
#if (QT_VERSION >= QT_VERSION_CHECK(5, 15, 0))
  LTDev::QtPdfViewerInitializer::initialize();
  QGuiApplication app(argc, argv);
#else
  QGuiApplication app(argc, argv);
  LTDev::QtPdfViewerInitializer::initialize();
#endif

  // Delete QtPdfViewer instance on app close
  QObject::connect(&app, &QGuiApplication::aboutToQuit, LTDev::QtPdfViewerInitializer::getInstance(), LTDev::QtPdfViewerInitializer::deleteInstance);

 QQmlApplicationEngine engine;

 // Needed to import the custom module
 engine.addImportPath("qrc:/");
 engine.addImportPath(":/");
  ...
}

• then, in qml import the library import it.ltdev.qt.qml.components 1.0, and use the provided PdfView class.

import it.ltdev.qt.qml.components 1.0 as LTDev

ApplicationWindow {
      ...

      LTDev.PdfView {
          id: pdfView

          anchors.fill: parent

          onViewerLoaded: {
              // Load pdf only when viewer is ready
              pdfView.load("path/to/my/document.pdf")
          }

          onPdfLoaded: {
              // Pdf has been correctly loaded
          }

          onError: {
             // Some error occurred
             console.error("Error: ", message)
          }
      }
}

Anyway, for more info, give a look to the sources of the sample app :D

For the qt quick application where is the .pro file??
