iterates through child items of a control

eachChild(id: Id, callback: DataCallback<T>, direct?: boolean, checkItem?: (item: IDataItem) => boolean): void;

Parameters:

• id: string - the ID of a control
• callback: function - the function that will be applied to every child of the item
• direct: boolean - optional, defines whether the function should iterate through all children (of any level) of the specified item. If false, the function will iterate only through the first-level children of the item; true by default.

    // disable items
    item.$disabled = true;
});
toolbar.paint();
