Field Detail

ORIENTATION_VERTICAL

public static int ORIENTATION_VERTICAL

Components are to be layed out vertically.

ORIENTATION_HORIZONTAL

public static int ORIENTATION_HORIZONTAL

Components are to be layed out horizontally.

Constructor Detail

OrderedLayout

public OrderedLayout()

Create a new ordered layout. The order of the layout is ORIENTATION_VERTICAL.

OrderedLayout

public OrderedLayout(int orientation)

Create a new ordered layout. The orientation of the layout is given as parameters.

Parameters:

orientation - Orientation of the layout.

Method Detail

getTag

public java.lang.String getTag()

Get component UIDL tag.

Specified by:

getTag in class AbstractComponent

Returns:

Component UIDL tag as string.

addComponent

public void addComponent(Component c)

Add a component into this container. The component is added to the right or under the previous component.

Specified by:

addComponent in interface ComponentContainer

Overrides:

addComponent in class AbstractComponentContainer

Parameters:

c - The component to be added.

addComponentAsFirst

public void addComponentAsFirst(Component c)

Add a component into this container. The component is added to the left or on top of the other components.

Parameters:

c - The component to be added.

addComponent

public void addComponent(Component c,
                         int index)

Add a component into indexed position in this container.

Parameters:

c - The component to be added.

index - Index of the component position. The components currently in and after the position are shifted forwards.

removeComponent

public void removeComponent(Component c)

Remove a component from this container.

Specified by:

removeComponent in interface ComponentContainer

Overrides:

removeComponent in class AbstractComponentContainer

Parameters:

c - The component to be removed.

getComponentIterator

public java.util.Iterator getComponentIterator()

Get component container iterator for going trough all the components in the container.

Specified by:

getComponentIterator in interface ComponentContainer

Returns:

Iterator of the components inside the container.

paintContent

public void paintContent(PaintTarget target)
                  throws PaintException

Paint the content of this component.

Overrides:

paintContent in class AbstractComponent

Parameters:

target - target UIDL stream where the component should paint itself to

Throws:

PaintException - The paint operation failed.

getOrientation

public int getOrientation()

Get the orientation of the container.

Returns:

Value of property orientation.

setOrientation

public void setOrientation(int orientation)

Set the orientation of the container.

Parameters:

orientation - New value of property orientation.

replaceComponent

public void replaceComponent(Component oldComponent,
                             Component newComponent)

Description copied from interface: ComponentContainer

Replace a component in the container with another one without changing position.

This method replaces component with another one is such way that the new component overtakes the position of the old component. If the old component is not in the container, the new component is added to the container. If the both component are already in the container, their positions are swapped. Component attach and detach events should be taken care as with add and remove.

Specified by:

replaceComponent in interface ComponentContainer

Parameters:

oldComponent - The old component that will be replaced.

newComponent - The new component to be replaced
