Conditions.talent.treeWidget

dependency

Call as

Conditions.talent.treeWidget(parent, spec, value, update)

Record the dependency Conditions.talent.treeWidget, then call it by that name. A namespaced call does not pass self: use a colon call or pass the object yourself.

What it does

Builds the TALENT editor controls for Classic talent trees: a tree dropdown, a talent icon, a talent dropdown for the chosen tree, and a Points comparison. Changing the tree clears the talent (and the comparison when switching from another layout), and every change calls update.

Arguments

NameTypeWhat it does
parenttableCondition widget group the control is added to.
specnumber | nilSpecialization the editor is for; on progression clients a value from 1 to 4 also selects the talent group to read.
valuetableSaved TALENT condition settings; the control reads and rewrites its layout, tree, talent, node, entry, operator and value fields.
updatefunctionCalled with no arguments after every change so the editor can refresh.

Returns

Nothing.

Editions

Built In helpers are registered on every edition. What differs is the game API they read; where one is missing the helper falls back or returns nil with a reason.

It reads no game API directly.

How the addon calls it

  • Talent (widget)
    if current=="tree" then treeWidget(parent,spec,value,update)
