Examples of org.mt4j.components.MTComponent.addChild()

org.mt4j.components.MTComponent.addChild()
Adds a component as a child to this component. By doing this, it will be under the influence of the parents transformations.
NOTE: adding children during traversal of the component hierarchy will result in a concurrent modification error (e.g. in methods like drawComponent or updateComponent). To resolve this, we can use the AddNodeActionThreadSafe class to add as an IPreDrawAction to our current scene (looking something like this: yourScene.addPreDrawAction(new AddNodeActionThreadSafe(..));) The component will then be added before the next rendering loop. @param tangibleComp the tangible comp
