Hi David I wrote a number of widgets some time ago (before the introduction of Action Widgets) where parameters are passed up through a stack of widgets (stacked button widgets.) These may be found here. <http://gwiz.tiddlyspot.com/>
This mechanism is, however, cumbersome when compared with the Action Widget mechanism -- I would stick with Action Widgets for this functionality. You might also be interested in the example at the bottom of the 'keep Operator examples' tiddler, from the ActionListops widget wiki <http://listops.tiddlyspot.com/>. This makes use of a couple of additional filters, the cycle[] filter and the keep[] filter which aren't yet in the core. In this case, the buttons search the listed tiddlers for the first item matching a list of items in a reference list, then exchange this item for the next item in the reference list i.e. if the tiddler were 'tagged' with "red green blue", and the reference list were "red yellow orange green blue", the first click of the button would leave the tiddler tagged with "yellow", the second click with "orange", and the third click with "green". This is similar to your intended functionality. regards On Friday, 19 August 2016 15:30:21 UTC+2, David Someone wrote: > > Hi all, could I kindly ask for some help in adding fieldmangler / > action-sendmessage as a child widget to buttons? > > I've made a copy of buttons.js and I'm trying to put action-sendmessage in > the body of the code as a child widget.
