Class TInternalChildrenControls
Unit
Declaration
type TInternalChildrenControls = class(TObject)
Description
List of UI controls, with a parent control and container. Ordered from back to front. Used for TCastleContainer.Controls.
User code should not create instances of this class. The only way to have an instance of it, is to get a container, by creating a TCastleWindow or TCastleControl. Then you can access MyWindow.Container.Controls.
User code should rarely need to use methods and properties of this class. That's because most TCastleUserInterface controls should be added to TCastleView, so only TCastleView instances should be present at the top-level of the UI hierarchy in TInternalChildrenControls. And you should manage TCastleView instances using TCastleContainer.View, TCastleContainer.PushView etc. that will make it added / removed from the TInternalChildrenControls automatically.
