问题 I'm tyring to figure out how I can accelerate drawing of a QML scene that shows a game map made up of hexagonal tiles. Each tile is a qml item dynamically instantiated via JavaScript on startup. The highlight property of each tile is toggled based on mouse-over movement. The tile object looks similar to this: Item { id: tile x: // is set to fixed value by JS code on item instantiation y: // is set to fixed value by JS code on item instantiation width: // is set to fixed value by JS code on
