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,
                                  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.MarginHandler.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 - new expand ratio (greater or equal to 0)

Throws:

IllegalArgumentException - if the expand ratio is negative or the component is not a direct child of the layout

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.

addLayoutClickListener

public Registration addLayoutClickListener(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.

Specified by:

addLayoutClickListener in interface LayoutEvents.LayoutClickNotifier

Parameters:

listener - The listener to add

Returns:

a registration object for removing the listener

See Also:

Registration

removeLayoutClickListener

@Deprecated
public void removeLayoutClickListener(LayoutEvents.LayoutClickListener listener)

Deprecated.

Description copied from interface: LayoutEvents.LayoutClickNotifier

Removes an LayoutClickListener.

Specified by:

removeLayoutClickListener 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.

setMargin

public void setMargin(boolean enabled)

Description copied from interface: Layout.MarginHandler

Enable layout margins. Affects all four sides of the layout. This will tell the client-side implementation to leave extra space around the layout. The client-side implementation decides the actual amount, and it can vary between themes.

Specified by:

setMargin in interface Layout.MarginHandler

Parameters:

enabled - true if margins should be enabled on all sides, false to disable all margins

getMargin

public MarginInfo getMargin()

Specified by:

getMargin in interface Layout.MarginHandler

Returns:

MarginInfo containing the currently enabled margins.

setMargin

public void setMargin(MarginInfo marginInfo)

Description copied from interface: Layout.MarginHandler

Enable margins for this layout.

NOTE: This will only affect the space around the components in the layout, not space between the components in the layout. Use Layout.SpacingHandler.setSpacing(boolean) to add space between the components in the layout.

See the reference manual for more information about CSS rules for defining the size of the margin.

Specified by:

setMargin in interface Layout.MarginHandler

Parameters:

marginInfo - MarginInfo object containing the new margins.

The component is responsible not only for writing its own state but also for ensuring that its children write their state to the design.

This method must not modify the component state.

Specified by:

writeDesign in interface Component

Overrides:

writeDesign in class AbstractComponent

Parameters:

design - The element to write the component state to. Any previous attributes or child nodes are not cleared.

designContext - The DesignContext instance used for writing the design

getCustomAttributes

protected Collection<String> getCustomAttributes()

Description copied from class: AbstractComponent

Returns a collection of attributes that should not be handled by the basic implementation of the AbstractComponent.readDesign(Element, DesignContext) and AbstractComponent.writeDesign(Element, DesignContext) methods. Typically these are handled in a custom way in the overridden versions of the above methods

Overrides:

getCustomAttributes in class AbstractComponent

Returns:

the collection of attributes that are not handled by the basic implementation
