Question

What is the difference between these three:

this.parent;
this.parentApplication;
this.parentDocument;

when i call this in a popupWindow.

Addition to this: I have a tabnavigator as a Custom component. When I click some Button on tabnavigator, the popup(titlewindow) will display. Now I want to call a function defined in the tabnavigator from popup(titlewindow). Suggest some ideas.

Answer 1

I am not sure with the this.parent but confirm with this.parentApplication and this.parentDocument

let’s take a tree of that for easy understand.

                     1
                    / \
                   2   3
                  /|\   \
                 4 5 6   7
                    \     \
                     8     9

1 – ParentDocument:1 – ParentApplication:1

2 – ParentDocument:1 – ParentApplication:1

3 – ParentDocument:1 – ParentApplication:1

4 – ParentDocument:2 – ParentApplication:1

5 – ParentDocument:2 – ParentApplication:1

6 – ParentDocument:2 – ParentApplication:1

7 – ParentDocument:3 – ParentApplication:1

8- ParentDocument:5 – ParentApplication:1

9 – ParentDocument:7 – ParentApplication:1
