Method Detail
-
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 classAbstractConnector
-
onStateChanged
public void onStateChanged(StateChangeEvent stateChangeEvent)
Description copied from interface:
StateChangeEvent.StateChangeHandler
Notifies the event handler that the state has changed.
Specified by:
onStateChanged
in interfaceStateChangeEvent.StateChangeHandler
Overrides:
onStateChanged
in classAbstractComponentConnector
Parameters:
stateChangeEvent
- the state change event with details about the change
-
getState
public PopupViewState getState()
Description copied from class:
AbstractConnector
Returns the shared state object for this connector. Override this method to define the shared state type for your connector.
Specified by:
getState
in interfaceComponentConnector
Specified by:
getState
in interfaceServerConnector
Overrides:
getState
in classAbstractComponentConnector
Returns:
the current shared state (never null)
-
updateCaption
public void updateCaption(ComponentConnector childConnector)
Description copied from interface:
HasComponentsConnector
Update child components caption, description and error message.
Each component is responsible for maintaining its caption, description and error message. In most cases components doesn't want to do that and those elements reside outside of the component. Because of this layouts must provide service for it's childen to show those elements for them.
Specified by:
updateCaption
in interfaceHasComponentsConnector
Parameters:
childConnector
- Child component for which service is requested.
-
getWidget
public VPopupView 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:
getWidget
in interfaceHasWidget
Overrides:
getWidget
in classAbstractComponentConnector
Returns:
The widget associated with this paintable
-
postLayout
public void postLayout()
Description copied from interface:
PostLayoutListener
Method invoked by
LayoutManager
to notify the connector that a layout phase has ended. This method can be used to finalize internal layouting, but it is not allowed to change the its own external size or modify the conditions for any children.Specified by:
postLayout
in interfacePostLayoutListener
-
onConnectorHierarchyChange
public void onConnectorHierarchyChange(ConnectorHierarchyChangeEvent connectorHierarchyChangeEvent)
Description copied from interface:
ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler
Called by the framework when the list of child components of the connector implementing this interface has changed. The implementation is responsible for attaching the widgets of any new children and detaching the widgets of any removed children. Implementations should typically also make sure that the child widgets are attached according to the ordering of the child components.
This method is called after the shared state and hierarchy data (i.e.
AbstractHasComponentsConnector.setChildComponents(List)
) been updated for all affected connectors, but before updating captions, firing state change events, invoking updateFromUIDL for legacy connectors, invoking RPC and starting the layout phase.Please note that hierarchy change events are fired in a non-deterministic order when a message from the server causes multiple parts of the hierarchy to change. This means that the old parent connector might not yet have detached a child widget and that the widget of a removed child might already have been attached by its new parent.
Specified by:
onConnectorHierarchyChange
in interfaceConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler
Parameters:
connectorHierarchyChangeEvent
- the event with information about the hierarchy change
-
onVisibilityChange
public void onVisibilityChange(VisibilityChangeEvent event)
Description copied from interface:
VisibilityChangeHandler
Handle popup visibility change.
Specified by:
onVisibilityChange
in interfaceVisibilityChangeHandler
Parameters:
event
- the visibility change event
