The specific value required for a each parameterized attribute is different and is often application specific thus requiring some experimentation. ![]() See hs.axuielement:parameterizedAttributeValue for a description of the return values and hs.axuielement:parameterizedAttributeNames to get a list of parameterized values that the element supports Object:WithParameter(value) is a shortcut for `object:parameterizedAttributeValue(attribute, value) See hs.axuielement:performAction for a description of the return values and hs.axuielement:actionNames to get a list of actions that the element supports.object:do() is a shortcut for object:performAction(action).If detecting accessiblity errors that may occur is necessary, you must use the formal method hs.axuielement:attributeValue to get the "AXChildren" attribute. ![]() object is a shortcut for object:attributeValue("AXChildren").#object is a shortcut for #object:attributeValue("AXChildren").Note that object:attributeValue("AXChildren") may return nil if the object does not have the AXChildren attribute the shortcut does not have this limitation.end is a shortcut for for i,v in pairs(object:attributeValue("AXChildren") or ) do. Iteration over Child Elements (AXChildren): See hs.axuielement:allAttributeValues for details and a workaround. This is because the value of nil prevents the key from being retained in the table returned. By default, hs.axuielement:allAttributeValues will not include key-value pairs for which the attribute (key) exists for the element but has no assigned value (nil) at the present time.If detecting accessiblity errors that may occur is necessary, you must use one of the formal approaches hs.axuielement:allAttributeValues or hs.axuielement:attributeNames and hs.axuielement:attributeValue.end or for k,v in pairs(object:allAttributeValues()) do. end is a shortcut for for k,_ in ipairs(object:attributeNames()) do local v = object:attributeValue(k). If you require confirmation of the change, you will need to check the value of the attribute with one of the methods described above after setting it.the element may not be settable (surprisingly this does not return an error, even when hs.axuielement:isAttributeSettable returns false for the attribute specified).internal logic within the receiving application may decline to accept the newly assigned value.Note that setting an attribute value is not guaranteeed to work with either method:. ![]()
