public class Container

extends Component

Components added to a container are tracked in a list. The order of the list will define the components' front-to-back stacking order within the container. If no index is specified when adding a component to a container, it will be added to the end of the list (and hence to the bottom of the stacking order).

Container()

Constructs a new Container.

Container(LayoutManager)

Constructs a new Container with the speicified layout manager.

add(Component)

Adds the specified component to this container.

add(String, Component)

Adds the specified component to this container.

doLayout()

Does a layout on this Container.

findComponentAt(int, int)

Find the component at the specified x and y position

getComponent(int)

Get the specific component

getComponentCount()

Get the specific component

getLayout()

Gets the layout manager for this container.

getMinimumSize()

Returns the minimum size of this container.

paint(Graphics)

Paints the container.

processMouseEvent(MouseEvent)

This method attempts to distribute a mouse event to a lightweight component.

remove(Component)

Removes the component at the specified index from this container.

removeAll()

Paints the components in this container.

setLayout(LayoutManager)

Sets the layout manager for this container.

setMasterDrawRegion(Rectangle)

Set the master drawing region for this container and it's children.

validate()

Validates this Container and all of the components contained within it.

 public Container()

Constructs a new Container. Containers can be extended directly, but are lightweight in this case and must be contained by a parent somewhere higher up in the component tree that is native. (such as Frame for example).

 public Container(LayoutManager layoutManager)

Constructs a new Container with the speicified layout manager. Containers can be extended directly, but are lightweight in this case and must be contained by a parent somewhere higher up in the component tree that is native. (such as Frame for example).

Parameters:

layoutManager - the desired layout manager for this container

 public Component add(Component component)

Adds the specified component to this container.

Parameters:

comp - the component to be added

 public Component add(String where,
                      Component c)

Adds the specified component to this container.

Parameters:

where - the position where the component is to be added

comp - the component to be added

 public void doLayout()

Does a layout on this Container. Most programs should not call this directly, but should invoke validate instead.

Overrides:

doLayout in class Component

See Also:

setLayout, validate

 public int getComponentCount()

Get the specific component

 public Component getComponent(int comp)

Get the specific component

 public Component findComponentAt(int x,
                                  int y)

Find the component at the specified x and y position

 public Dimension getMinimumSize()

Returns the minimum size of this container.

Overrides:

getMinimumSize in class Component

 public LayoutManager getLayout()

Gets the layout manager for this container.

See Also:

doLayout, setLayout

 public void paint(Graphics g)

Paints the container. This forwards the paint to any lightweight components that are children of this container.

Parameters:

g - the specified Graphics window

Overrides:

paint in class Component

 public void processMouseEvent(MouseEvent me)

This method attempts to distribute a mouse event to a lightweight component. It tries to avoid doing any unnecessary probes down into the component tree to minimize the overhead of determining where to route the event, since mouse movement events tend to come in large and frequent amounts.

Overrides:

processMouseEvent in class Component

 public void removeAll()

Paints the components in this container.

Parameters:

g - the specified Graphics window

 public void remove(Component c)

Removes the component at the specified index from this container.

Parameters:

index - the index of the component to be removed

See Also:

add

 public void setLayout(LayoutManager mgr)

Sets the layout manager for this container.

Parameters:

mgr - the specified layout manager

See Also:

doLayout, getLayout

 public void validate()

Validates this Container and all of the components contained within it.

Overrides:

validate in class Component

See Also:

validate, invalidate

 public void setMasterDrawRegion(Rectangle region)

Set the master drawing region for this container and it's children.

Parameters:

region - the specified master drawing region

Overrides:

setMasterDrawRegion in class Component
