~~Title: Efl.Pack_Linear~~
====== Efl.Pack_Linear (interface) ======

===== Description =====

%%Common interface for objects (containers) with multiple contents (sub-objects) which can be added and removed at runtime in a linear fashion.%%

%%This means the sub-objects are internally organized in an ordered list.%%
