SCContainerView an abstract superclass for container views

Inherits from: Object : SCView

Users will not normally directly create instances of SCContainerView, but only use it through its subclasses. It provides the basic mechanisms for container views of various kinds, which are used for placing and grouping widgets in a window.

Some Important Issues Regarding SCContainerView

Container views are meant for placing and grouping child views and widgets. While they accept key actions, many do not accept mouse cklicks or drags. The exception is SCTopView and its subclasses.

Accessing Instance and Class Variables

decorator_(arg1)

decorator

An automatic layout management for a container. Currently the only one existing is FlowLayout.

(note: Crucial Library also has a useful layout tool called GridLayout.)

addFlowLayout(margin, gap)

A convenience utility which sets decorator to FlowLayout and returns the decorator. See FlowLayout for examples.

margin - An instance of Point

gap - An instance of Point

children

An array containing all the views (children) contained in the the container.

Adding and Removing Subviews

add (child)

Adds a view to children. The placement of the child view will depend on the the decorator, and the child's bounds. Nomally you don't need to call this directly, since subviews call it automatically when you create them.

removeAll

Removes all children from the view

Subclassing and Internal Methods

The following methods are usually not used directly or are called by a primitive. Programmers can still call or override these as needed.

init (argParent, argBounds)

prRemoveChild (child) private method

prClose private method
