Conditions.talent.treePicker

Call as

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

Record the dependency Conditions.talent.treePicker, 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 tree dropdown for the TALENT_TREE_POINTS and PRIMARY_TALENT_TREE editors, listing the client's talent trees, storing the selection in value.tree and calling update. Shows a note when the client has no Classic talent-tree layout; the dropdown is disabled when there are no trees or value.disabled is true.

Arguments

Name	Type	What it does
`parent`	`table`	Condition widget group the control is added to.
`spec`	`number \| nil`	Specialization the editor is for; on progression clients a value from 1 to 4 also selects the talent group to read.
`value`	`table`	Saved condition settings; the tree field is read and written, and disabled is honored.
`update`	`function`	Called 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.
