Method Detail

delegateCaptionHandling

public boolean delegateCaptionHandling()

Description copied from interface: ComponentConnector

Return true if parent handles caption, false if the paintable handles the caption itself.

Overrides:

delegateCaptionHandling in class AbstractComponentConnector

Returns:

true if caption handling is delegated to the parent, false if parent should not be allowed to render caption

init

protected void init()

Description copied from class: AbstractConnector

Called when the connector has been initialized. Override this method to perform initialization of the connector.

Overrides:

init in class AbstractConnector

onUnregister

public void onUnregister()

Description copied from interface: ServerConnector

Event called when connector has been unregistered.

Specified by:

onUnregister in interface ServerConnector

Overrides:

onUnregister in class AbstractComponentConnector

updateFromUIDL

public void updateFromUIDL(UIDL uidl,
                           ApplicationConnection client)

Specified by:

updateFromUIDL in interface Paintable

updateCaption

public void updateCaption(ComponentConnector component)

Description copied from interface: ComponentContainerConnector

Update child components caption, description and error message.

Parameters:

component - Child component for which service is requested.

onBeforeShortcutAction

public void onBeforeShortcutAction(com.google.gwt.user.client.Event e)

Description copied from interface: ShortcutActionHandler.BeforeShortcutActionListener

This method is called by ShortcutActionHandler before firing the shortcut if the Paintable is currently focused (aka the target of the shortcut action). Eg. a field can update its possibly changed value to the server before shortcut action is fired.

Specified by:

onBeforeShortcutAction in interface ShortcutActionHandler.BeforeShortcutActionListener

Parameters:

e - the event that triggered the shortcut action

getWidget

public VWindow getWidget()

Description copied from class: AbstractComponentConnector

Returns the widget associated with this paintable. The widget returned by this method must not changed during the life time of the paintable.

Specified by:

Overrides:

getWidget in class AbstractComponentConnector

Returns:

The widget associated with this paintable

createWidget

protected com.google.gwt.user.client.ui.Widget createWidget()

Description copied from class: AbstractComponentConnector

Creates and returns the widget for this VPaintableWidget. This method should only be called once when initializing the paintable.

Specified by:

createWidget in class AbstractComponentConnector

Returns:

onConnectorHierarchyChange

public void onConnectorHierarchyChange(ConnectorHierarchyChangeEvent event)

Specified by:

onConnectorHierarchyChange in interface ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler

Overrides:

onConnectorHierarchyChange in class AbstractComponentContainerConnector

layout

public void layout()

Specified by:

getState in interface Connector

Overrides:

Returns:

current shared state (not null)

setWindowOrderAndPosition

public void setWindowOrderAndPosition()
