Package com.flowingcode.vaadin.addons.easygrid.actions

Class RowActionsManager<T>

java.lang.Object

com.flowingcode.vaadin.addons.easygrid.actions.RowActionsManager<T>

Type Parameters:

T - the grid bean type

All Implemented Interfaces:

Serializable

public class RowActionsManager<T>
extends Object
implements Serializable

Manages the row actions column for an EasyGrid. Maintains the list of registered EasyRowAction instances, the render style (inline buttons, an overflow menu, or a context menu; see RowActionsStyle), and delegates all visual concerns to a RowActionsRenderer.

A manager instance is created lazily, on first access through its grid wrapper. The instance itself is lightweight; the actions Grid.Column it manages is created lazily (on the first renderer update or getActionsColumn() call) and stays hidden until the first action is added.
