  Hi,

  The module was released with 5.10 but you can still try to build it with your version of Qt. Otherwise there are several projects you can find on GitHub that implements the protocol even some Qt based solution.

  After some code-mining the above loop should be equivalent to:

  for (int i = topLeft.row(); i < maxRow; ++i) { const int maxColumn = bottomRight.column() - ((i==maxRow-1) ? 1:0); for (int j = topLeft.column()+ ((i==topLeft.row()) ? 1:0); j < maxColumn; ++j) { d->viewport->update(visualRect(d->model->index(i, j, parent))); } }

  The updates are compressed trough QWidgetBackingStore::markDirty. I know the docs mention this but I couldn't find it in QCoreApplication::compressEvent so I went spelunking, albeit rather short lived.

  this has nothing to do with Qt.
  std::to_string is C++11, you have to make sure you have a recent enough compiler and to enable C++11 features. If you use Qt Creator you should add CONFIG += c++11 in your .pro file and re-run qmake

  Alternatively you can #include <sstream> and use std::stringstream gstream; gstream << 4; std::string g=gstream.str();

  AFAIK, if you publish a Qt App on Play Store (or other stores) you need to keep a valid license forever. Because the license terms says you can't "distribuite" a Qt App without a license.

  This is a big problem for indipendent developers with small badgets....
