Interface ChildChangedAware

All Known Implementing Classes:

Combobox.ExtraCtrl, Fisheyebar.ExtraCtrl, Grid.ExtraCtrl, Listbox.ExtraCtrl, Tabbox.ExtraCtrl, Tree.ExtraCtrl

public interface ChildChangedAware

Implemented by the object returned by ComponentCtrl.getExtraCtrl() if a component requires the z.chchg command, when any of its children and descendants are changed.

Once a component implements this interface and isChildChangedAware() returns true, the z.chchg command is sent to the client to update the visual representation. For example, a grid uses two tables to implement header and body, and then it has to re-align the header once any of its descendants is changed.
