Re: [Interest] [Qt3D] QAbstractCameraController & escape key

[Andy]

I filed a bug report:

   https://bugreports.qt.io/browse/QTBUG-69802

I couldn't figure out how to turn it off through the public API, but I did
come up with a fragile hack to turn it off.

In your inherited camera controller (or, subclass one of the existing ones):

// Find and delete the escape key QActionInput.

// This is a workaround for the change to QAbstractCameraController in Qt 5.11

// which added an escape key handler that performs a "view all" on the scene.

//   https://codereview.qt-project.org/#/c/226879/

//   https://bugreports.qt.io/browse/QTBUG-69802
void inheritedCameraController::_deleteEscapeHandler()

{

   QList   list =
findChildren();


   for ( auto actionInput : list )

   {

  if ( actionInput->buttons().count() != 1 )

  {

 continue;

  }


  if ( actionInput->buttons().at( 0 ) == Qt::Key_Escape )

  {

 delete actionInput;

  }

   }

}

[Interest] [Qt3D] QAbstractCameraController & escape key

[Andy]

Back in April, a commit added the functionality that the escape key does a
"view all" on the scene.

 https://codereview.qt-project.org/#/c/226879/

How do I prevent this? I can't figure out a way to turn it off/override it
in my derived camera controller.

I have a ground plane and a model in the middle of it and when the user
hits escape it zooms the camera way out and it looks terrible (and it's
confusing).

This feels like an application-specific functionality that doesn't belong
in this abstract base class.
