~~Title: Efl.Canvas.Object.invalidate~~
====== Efl.Canvas.Object.invalidate ======

===== Description =====

%%Implement this method to perform special actions when your object loses its parent, if you need to.%%

%%It is called when the parent reference is lost or set to %%''NULL''%%. After this call returns, %%[[:develop:api:efl:object:property:invalidated|Efl.Object.invalidated]]%% is set to %%''true''%%. This allows a simpler tear down of complex hierarchies, by performing object destruction in two steps, first all object relationships are broken and then the isolated objects are destroyed. Performing everything in the %%[[:develop:api:efl:object:method:destructor|Efl.Object.destructor]]%% can sometimes lead to deadlocks, but implementing this method is optional if this is not your case. When an object with a parent is destroyed, it first receives a call to %%[[:develop:api:efl:object:method:invalidate|Efl.Object.invalidate]]%% and then to %%[[:develop:api:efl:object:method:destructor|Efl.Object.destructor]]%%. See the Life Cycle section in this class' description.%%
