Hi, 

Seems in Tizen native app, no such c api can do this.

Possible the edc layout can do this, define a group with two swallow part, use rel2 & rel2  to define them relative position. 

Hi, 

Just for more easy to understanding the layout, you can create the Sample Alignment UI sample, and find the .edc file which the content I have list below, please pay attention to the code :

               rel1.to: "bg_rect";
               rel2.to: "bg_rect";
               align: 0.0 0.5;

collections {
   group { name: "main";
      parts {
         part { name: "bg_rect";
            type: RECT;
            scale: 1;
            description { state: "default" 0.0;
               fixed: 1 1;
               rel1 { relative: 0.0 0.0; }
               rel2 { relative: 1.0 1.0; }
               color: 0 0 0 255;
            }
         }
         part { name: "middle_container_base";
            type: RECT;
            scale: 1;
            description { state: "default" 0.0;
               max: 50 50;
               fixed: 1 1;
               rel1.to: "bg_rect";
               rel2.to: "bg_rect";
               align: 0.5 0.5;
               color: 0 255 0 128;
            }
         }
