Manage hierarchy of open GRAMPS windows.
|
|
|
|
This class's purpose is to manage the hierarchy of open windows.
|
|
The idea is to maintain the tree of branches and leaves.
|
|
A leaf does not have children and corresponds to a single open window.
|
|
A branch has children and corresponds to a group of windows.
|
|
|
|
We will follow the convention of having first leaf in any given
|
|
branch represent a parent window of the group, and the rest of the
|
|
children leaves/branches represent windows spawned from the parent.
|
|
|
|
The tree structure is maintained as a list of items.
|
|
Items which are lists are branches.
|
|
Items which are not lists are leaves.
|
|
|
|
Lookup of an item is done via track sequence. The elements of
|
|
the track sequence specify the lookup order: [2,3,1] means
|
|
'take the second item of the tree, take its third child, and
|
|
then the first child of that child'.
|
|
|
|
Lookup can be also done by ID for windows that are identifiable.
