After months of mostly lurking here, I've begun to try to get my head around
the code architecture of of Qooxdoo. To try to accomplish this, I've read all
of the on-line docs, built a working demo tree, and am attempting to trace
through the code with an initial goal in mind: some additional configurability
to QxTree and friends.
I'm having trouble locating where in the code a QxTree is recursed into and
rendered (or, maybe what I want to know is where it is recursed and each
element of the tree _queued_ to be rendered).
As a first configurability option, I'm trying to enable display of the tree
*without* the 'Root' element. Using the example Tree_1.html as a basis, it
displays a tree like this:
Root
Desktop
Files
Workspace
Network
Trash
Inbox
Presets
Sent
Trash
...
I'd like to display that without the top 'Root' node, In other words, although
'Root' is the QxTree element with numerous QxFolder and QxFile elements below
it, I want to display the tree like this:
Desktop
Files
Workspace
Network
Trash
Inbox
Presets
Sent
Trash
...
I can't use SetVisibility() of the QxTree node because then the whole tree
(including all subtrees) becomes invisible. Similarly, the 'displayable'
property seems to affect the whole tree, and also doesn't appear to be
intended for external manipulation. I expect I need to add a new property
which causes QxTree to descend into subtrees so the QxFolders and QxFiles get
rendered, without rendering the QxTree itself.
Pointers to appropriate areas of code would be greatly appreciated!
Also, are there any additional architecture documents that describe the
complete flow of control? The online docs do a nice job of describing
individual components of the architecture, but nothing that I have found yet
brings it all together for the "big picture". Again, pointers greatly
appreciated!
Cheers,
Derrell
