Method Detail

synchronize

void synchronize(R parent,
               T model)

This method synchronizes the subtree rows (but not the parent row!) data with any data source.

If the parent row is null it must invoke the DataModelCallbackHandler.synchronize(GridDataModel) method. If there are expanded child rows of the parent their children must be synchronized recursively as well.
Note also that you must use GridPanel.unlock(TreeGridRow) method instead of the GridPanel.unlock() to improve perfomance.
See also DataModelCallbackHandler.synchronize(GridDataModel) for details about the synchronization process.

Parameters:

parent - is a parent row of the subtree.

model - is a data model.
