> Abstract class that is root most base class for all widgets and layouts in the NodeGui World.
|
||
|
||
*This class is used to add core properties to all widgets, layouts etc in NodeGui world.
|
||
Currently it helps us maintain references to the native C++ instance of the widget or layout.
|
||
It also helps in preventing gc of child elements of a layout or widget**
|
||
|
||
`Component` is an abstract class and hence no instances of the same should be created.
|
||
It exists so that we can add core functionalities to all widgets and layouts easily. This is an internal class.
|
||
|
||
Its the root base class in NodeGui world.
