TableConnector

public TableConnector()

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 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

getWidget

public VScrollTable 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 interface ComponentConnector

Overrides:

getWidget in class AbstractComponentConnector

Returns:

The widget associated with this paintable

updateCaption

public void updateCaption(ComponentConnector component)

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 interface HasComponentsConnector

Parameters:

component - Child component for which service is requested.

layoutVertically

public void layoutVertically()

Specified by:

layoutVertically in interface DirectionalManagedLayout

layoutHorizontally

public void layoutHorizontally()

Specified by:

layoutHorizontally in interface DirectionalManagedLayout

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 interface PostLayoutListener

isReadOnly

public boolean isReadOnly()

Description copied from interface: ComponentConnector

Checks if the connector is read only.

Specified by:

isReadOnly in interface ComponentConnector

Overrides:

isReadOnly in class AbstractComponentConnector

Returns:

true

getState

public com.vaadin.shared.ui.table.TableState 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 interface ComponentConnector

Specified by:

getState in interface ServerConnector

Overrides:

getState in class AbstractComponentConnector

Returns:

the current shared state (never null)

showSavedContextMenu

public void showSavedContextMenu(VScrollTable.ContextMenuDetails savedContextMenu)

Shows a saved row context menu if the row for the context menu is still visible. Does nothing if a context menu has not been saved.

Parameters:

savedContextMenu -

getTooltipInfo

public TooltipInfo getTooltipInfo(Element element)

Description copied from interface: ComponentConnector

Gets the tooltip info for the given element.

When overriding this method, ComponentConnector.hasTooltip() should also be overridden to return true in all situations where this method might return a non-empty result.

Specified by:

getTooltipInfo in interface ComponentConnector

Overrides:

getTooltipInfo in class AbstractComponentConnector

Parameters:

element - The element to lookup a tooltip for

Returns:

The tooltip for the element or null if no tooltip is defined for this element.

hasTooltip

public boolean hasTooltip()

Description copied from interface: ComponentConnector

Check whether there might be a tooltip for this component. The framework will only add event listeners for automatically handling tooltips (using ComponentConnector.getTooltipInfo(Element)) if this method returns true.

This is only done to optimize performance, so in cases where the status is not known, it's safer to return true so that there will be a tooltip handler even though it might not be needed in all cases.

Specified by:

hasTooltip in interface ComponentConnector

Overrides:

hasTooltip in class AbstractComponentConnector

Returns:

true if some part of the component might have a tooltip, otherwise false

onConnectorHierarchyChange

public void onConnectorHierarchyChange(ConnectorHierarchyChangeEvent connectorHierarchyChangeEvent)

Specified by:

onConnectorHierarchyChange in interface ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler

updateComponentSize

protected void updateComponentSize(java.lang.String newWidth,
                                   java.lang.String newHeight)

Description copied from class: AbstractComponentConnector

Updates the component size, invoking the layout manager if necessary.

Overrides:

updateComponentSize in class AbstractComponentConnector

Parameters:

newWidth - The new width as a CSS string. Cannot be null.

newHeight - The new height as a CSS string. Cannot be null.
