    Hi! I'm trying to get all visible items (indexes) of QML ListView, but i'm not shure how to realize this functionality. Maybe is some working approach exists? Thank you in advance.

      Guys, what do you think about method like that?

      function populateVisibleItems() {
              var aStartPos = chatView.contentY;
              var aFinishPos = aStartPos + chatView.height;
              var aStep = 15;
      
              var aCurrentItem, aPreviousItem;
      
              for( var aCurrPos = aStartPos; aCurrPos <= aFinishPos; aCurrPos += aStep ) {
                  aCurrentItem = chatView.itemAt( 0, aCurrPos );
                  if( aCurrentItem && aCurrentItem.objectName === "message_item" && aPreviousItem !== aCurrentItem ) {
                      console.log( aCurrentItem.text + " is visible" );
                      // do some stuff (push into array, etc..)
                  }
                  aPreviousItem = aCurrentItem;
              }
          }
