Method Detail

synchronize

void synchronize(T model)

This method should synchronize the data saved in the model with the persistent storage repository.

NOTE: you must take into account the fact that other grid controls can rise other evets during synchronization. It's better to lock them and unlock when synchronization is finished. Otherwise viewed content may be incorrect.
To do lock / unlock operations, use GridPanel.lock() and GridPanel.unlock() methods accordingly. Note, the unlock method also redraws the panel.

Parameters:

model - is a model to be used for additional parameters.
