Constructor Detail

AbstractLayout

public AbstractLayout()

Method Detail

getState

public AbstractLayoutState 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 AbstractComponent

Returns:

updated component shared state

setMargin

public void setMargin(boolean enabled)

Description copied from interface: Layout

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

getMargin

public Layout.MarginInfo getMargin()

Specified by:

getMargin in interface Layout.MarginHandler

Returns:

MarginInfo containing the currently enabled margins.

setMargin

public void setMargin(Layout.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 #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.

setMargin

public void setMargin(boolean topEnabled,
                      boolean rightEnabled,
                      boolean bottomEnabled,
                      boolean leftEnabled)

Description copied from interface: Layout

Enable specific layout margins. This will tell the client-side implementation to leave extra space around the layout in specified edges, clockwise from top (top, right, bottom, left). The client-side implementation decides the actual amount, and it can vary between themes.

Specified by:

setMargin in interface Layout
