com.vaadin.ui.LegacyComponent API 8.27.7 | Vaadin

com.vaadin.ui.

All Superinterfaces:

ClientConnector, Component, Connector, ConnectorEventListener, EventListener, Serializable, SerializableEventListener, Sizeable, VariableOwner

All Known Implementing Classes:

ColorPickerPopup, CustomLayout, DragAndDropWrapper, LegacyWindow, MenuBar, Panel, UI, Upload, Window
```
@Deprecated
public interface LegacyComponent
extends VariableOwner, Component, ConnectorEventListener
```
Deprecated.
As of 7.0. This class is only intended to ease migration and should not be used for new projects.

Interface provided to ease porting of Vaadin 6 components to Vaadin 7. By implementing this interface your Component will be able to use paintContent(PaintTarget) and VariableOwner.changeVariables(Object, java.util.Map) just like in Vaadin 6.

Since:

7.0.0

- Method Detail
  - paintContent
```
void paintContent(PaintTarget target)
           throws PaintException
```
    Deprecated.
    
    Paints the Paintable into a UIDL stream. This method creates the UIDL sequence describing it and outputs it to the given UIDL stream.
    
    It is called when the contents of the component should be painted in response to the component first being shown or having been altered so that its visual representation is changed.
    
    Parameters:
    
    target - the target UIDL stream where the component should paint itself to.
    
    Throws:
    
    PaintException - if the paint operation failed.
  - markAsDirty
```
void markAsDirty()
```
    Deprecated.
    
    (non-Javadoc) Marks that this connector's state might have changed. When the framework is about to send new data to the client-side, it will run ClientConnector.beforeClientResponse(boolean) followed by ClientConnector.encodeState() for all connectors that are marked as dirty and send any updated state info to the client.
    For a LegacyComponent, markAsDirty will also cause paintContent(PaintTarget) to be called before sending changes to the client.
