Custom layout slots containing the components.

Constructor Detail

AbstractOrderedLayout

public AbstractOrderedLayout()

Mapping from components to alignments (horizontal + vertical).

Method Detail

getState

public AbstractOrderedLayoutState getState()

Description copied from class: AbstractComponent

Returns the shared state bean with information to be sent from the server to the client. Subclasses should override this method and set any relevant fields of the state returned by super.getState().

Specified by:

getState in interface Connector

Specified by:

getState in interface Component

Overrides:

getState in class AbstractLayout

Returns:

updated component shared state

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.

See Also:

ComponentContainer.addComponent(Component)

addComponentAsFirst

public void addComponentAsFirst(Component c)

Adds 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)

Adds a component into indexed position in this container.

Parameters:

c - the component to be added.

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

removeComponent

public void removeComponent(Component c)

Removes the component from this container.

Specified by:

removeComponent in interface ComponentContainer

Overrides:

removeComponent in class AbstractComponentContainer

Parameters:

c - the component to be removed.

See Also:

ComponentContainer.removeComponent(Component)

getComponentIterator

public Iterator<Component> getComponentIterator()

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

Specified by:

getComponentIterator in interface HasComponents

Returns:

the Iterator of the components inside the container.

getComponentCount

public int getComponentCount()

Gets the number of contained components. Consistent with the iterator returned by getComponentIterator().

Specified by:

getComponentCount in interface ComponentContainer

Returns:

the number of contained components

replaceComponent

public void replaceComponent(Component oldComponent,
                             Component newComponent)

Description copied from interface: ComponentContainer

Replaces the 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.

setComponentAlignment

public void setComponentAlignment(Component childComponent,
                                  int horizontalAlignment,
                                  int verticalAlignment)

Description copied from interface: Layout.AlignmentHandler

Set alignment for one contained component in this layout. Alignment is calculated as a bit mask of the two passed values.

Specified by:

setComponentAlignment in interface Layout.AlignmentHandler

Parameters:

childComponent - the component to align within it's layout cell.

horizontalAlignment - the horizontal alignment for the child component (left, center, right). Use ALIGNMENT constants.

verticalAlignment - the vertical alignment for the child component (top, center, bottom). Use ALIGNMENT constants.

setComponentAlignment

public void setComponentAlignment(Component childComponent,
                                  Alignment alignment)

Description copied from interface: Layout.AlignmentHandler

Set alignment for one contained component in this layout. Use predefined alignments from Alignment class. Example: layout.setComponentAlignment(myComponent, Alignment.TOP_RIGHT);

Specified by:

setComponentAlignment in interface Layout.AlignmentHandler

Parameters:

childComponent - the component to align within it's layout cell.

alignment - the Alignment value to be set

getComponentAlignment

public Alignment getComponentAlignment(Component childComponent)

Description copied from interface: Layout.AlignmentHandler

Returns the current Alignment of given component.

Specified by:

getComponentAlignment in interface Layout.AlignmentHandler

Returns:

the Alignment

setSpacing

public void setSpacing(boolean spacing)

Description copied from interface: Layout.SpacingHandler

Enable spacing between child components within this layout.

NOTE: This will only affect the space between components, not the space around all the components in the layout (i.e. do not confuse this with the cellspacing attribute of a HTML Table). Use Layout.setMargin(boolean) to add space around the layout.

See the reference manual for more information about CSS rules for defining the amount of spacing to use.

Specified by:

setSpacing in interface Layout.SpacingHandler

Parameters:

spacing - true if spacing should be turned on, false if it should be turned off

isSpacing

public boolean isSpacing()

Specified by:

isSpacing in interface Layout.SpacingHandler

Returns:

true if spacing between child components within this layout is enabled, false otherwise

setExpandRatio

public void setExpandRatio(Component component,
                           float ratio)

This method is used to control how excess space in layout is distributed among components. Excess space may exist if layout is sized and contained non relatively sized components don't consume all available space.

Example how to distribute 1:3 (33%) for component1 and 2:3 (67%) for component2 : layout.setExpandRatio(component1, 1);
layout.setExpandRatio(component2, 2);

If no ratios have been set, the excess space is distributed evenly among all components.

Note, that width or height (depending on orientation) needs to be defined for this method to have any effect.

Parameters:

component - the component in this layout which expand ratio is to be set

ratio -

See Also:

Sizeable

getExpandRatio

public float getExpandRatio(Component component)

Returns the expand ratio of given component.

Parameters:

component - which expand ratios is requested

Returns:

expand ratio of given component, 0.0f by default.

addListener

public void addListener(LayoutEvents.LayoutClickListener listener)

Description copied from interface: LayoutEvents.LayoutClickNotifier

Add a click listener to the layout. The listener is called whenever the user clicks inside the layout. An event is also triggered when the click targets a component inside a nested layout or Panel, provided the targeted component does not prevent the click event from propagating. A caption is not considered part of a component. The child component that was clicked is included in the LayoutEvents.LayoutClickEvent. Use #removeListener(LayoutClickListener) to remove the listener.

Specified by:

addListener in interface LayoutEvents.LayoutClickNotifier

Parameters:

listener - The listener to add

removeListener

public void removeListener(LayoutEvents.LayoutClickListener listener)

Description copied from interface: LayoutEvents.LayoutClickNotifier

Removes an LayoutClickListener.

Specified by:

removeListener in interface LayoutEvents.LayoutClickNotifier

Parameters:

listener - LayoutClickListener to be removed

getComponentIndex

public int getComponentIndex(Component component)

Returns the index of the given component.

Parameters:

component - The component to look up.

Returns:

The index of the component or -1 if the component is not a child.

getComponent

public Component getComponent(int index)
                       throws IndexOutOfBoundsException

Returns the component at the given position.

Parameters:

index - The position of the component.

Returns:

The component at the given index.

Throws:

IndexOutOfBoundsException - If the index is out of range.
