Technical notes on gear creation

Gear added by GUI drag&drop. Code flow analysis starting from the DropEvent:

• SchemaEditor::dropEvent
• | SchemaEditor::addGear(..)
• | | SchemaGui::addGear(..)
• | | | Gear gear = GearMaker::makeGear(fullname);*
• | | | | GearInfo *gearInfo = findGearInfo(fullName);
• | | | | thegear = gearInfo->createGearInstance();
• | | | | thegear->init();
• | | | | | (gear::)internalInit();
• | | | | GearInfo *gearInfo = findGearInfo(fullName);
• | | | GearGui ✳gearGui = new GearGui(gear);
• | | | gear->setGearGui(gearGui);
• | | | Schema::addGear(gear)
• | | | | gear.name(mangleUniqueGearName(gear.name()))
• | | | | gear.parentSchema(*this);
• | | | | emit gearAdded(*this, gear);
• | | | Schema::slotGearAdded(&Schema,&Gear)
• | | | | skipped -> if(!gear->getGearGui())gear.setGearGui(new GearGui(&gear));
• | | | Engine::onGearAdded
• | | | ?

Notes :

• Most events should be handled by QGraphicsScene (SchemaGui) directly, not bw QGraphicsView (SceneEditor). This is an unnecessary proxy

--> prePlay vs internalInit … what's the difference ?
