Hi all!
Guess I didn't solve my question last week about how to create a selectable
tree using the standard MythUI widgets...
Here's what I want to do:
I want to create a user interface with a tree. The tree hierarchy must be
shown in one single rectangular drawing area on the screen (i.e. like the
file tree in a standard Windows File Explorer). Before each node, I want to
put a plus-sign or minus-sign to indicate whether the node is expanded or
not. (If the node isn't expandable, no sign should be shown.)
With poor man's ASCII drawing, it's something like this I want to draw in
the UI:
[-] Root node
[+] First sub-node
[+] Second sub-node
[-] Third sub-node
[+] A sub-sub-node
[+] Fourth sub-node
I've been experimenting around with UIListTreeType, UIListType, and
UIManagedTreeListType. Depending on the widget type, it must be fed with a
GenericTree or a UIListGenericTree.... (Correct, or???)
Anyway: Since there is absolutely ZIP documentation or inline code-comments
about these widgets, I think it's a legit question to ask.... -- Just please
give me the 5 lines of code to initialize and show a fixed tree with a few
expandable nodes....
Plz help me... This is driving me absolutely nuts!
Cheers,
~Morten :-)
