How to access the data of a treeStruct (created by hiCreateTree) ?

Rein over 13 years ago

Hi,

For example,

a = hiCreateTree('a)

b = hiCreateTreeItem(......)

hiTreeAppendItems(a list(b))

How to access data b from a?

I try to use a~>?? to view data of a. But it is display (activeUT hiFieldSym a).

Thanks

Rein,

Using the example code below, I can do:

abTreeExample(geGetEditCellView()~>shapes)

with some layout view. Then I get:

items=hiGetTreeItems(abTreeExampleForm->treeField->choice)
(pathSeg arc line dot polygon
donut path label ellipse rect
)

itemStructs=foreach(mapcar item items symeval(item))

subtrees=foreach(mapcar itemStruct itemStructs symeval(hiGetTree(itemStruct)))

etc, etc.

Andrew.

etc, etc.
