Tizen Native API  7.0

In this example we add three buttons to a relative_container.

An interesting thing is children have chain-relationship like group behavior horizontally.

relative_container_example_02.png

In chain-relationship, relative_position parameter in function elm_relative_container_relation_xxx_set is ignored. the edge is positioned at the end of target edge. 0.5 and 0.3 won't affect the position of the edge.

Another interesting point is the align of chain group is affected only by the align of leftmost/topmost child. hint_align of bt1 will work:

But the others won't work:
