Method Detail

click

public void click(com.vaadin.event.MouseEvents.ClickEvent event)

Specified by:

click in interface com.vaadin.event.MouseEvents.ClickListener

setVisible

public void setVisible(boolean visible)

Specified by:

setVisible in interface com.vaadin.ui.Component

Overrides:

setVisible in class com.vaadin.ui.AbstractComponent

setSource

public void setSource(ResourceDownloadHandler source)

Sets the object source resource. The dimensions are assumed if possible. The type is guessed from resource.

Reintroduced, to ensure that only instances of ResourceDownloadHandler are passed as sources.

Parameters:

source - the source to set.

refresh

public void refresh()

Description copied from interface: UIComponent

This method is called from LSPS rendering engine. It should load all information needed from component definition record holder and apply them accordingly.

Note that this method should not attempt to apply any hints - hints are applied automatically after the component is refreshed. You however may read the hints value here - it is guaranteed that you will receive freshly updated hint value by reading UIComponentData.getHints().

Specified by:

refresh in interface UIComponent

handleConnectorRequest

public boolean handleConnectorRequest(com.vaadin.server.VaadinRequest req,
                                      com.vaadin.server.VaadinResponse resp,
                                      String path)
                               throws IOException

Specified by:

handleConnectorRequest in interface com.vaadin.server.ClientConnector

Overrides:

handleConnectorRequest in class com.vaadin.server.AbstractClientConnector

Throws:

IOException

getComponentData

public UIComponentData getComponentData()

Description copied from interface: UIComponent

Returns the component definition (LSPS RecordHolder instance which is subtype of "ui::Component") associated with this Vaadin component.

Specified by:

getComponentData in interface UIComponent

Returns:

component definition. The definition record instance must be present in root scope (screen context).

toString

public String toString()

Overrides:

getWidget

public com.vaadin.ui.AbstractComponent getWidget()

Description copied from interface: UIComponent
