h, You should have highlighted the _not_  ... I did only see/read *for

I do have a widget, which is called <$trigger actions=<> /> ... 
It is "triggered" whenever the widget is rendered or re-rendered. ... 

So it has some potential to completely brick your wiki, if done wrong. ... 

The risk to loose data is especially high, while developing the action-code 
and the "preview pane" is active. Because <$action-setfield .. with wrong 
parameters can completely ruin tiddler content. ... So be warned  
BACKUP - BACKUP  - BACKUP 

see: https://wikilabs.github.io/editions/trigger/

There is no documentation yet. So you have to open the tiddlers in the 
link, to see what's going on. 

I would implement the development code like this: 

title: myFooter
tags: $:/tags/ViewTemplate

<$list filter="[all[current]tag[test]]">
<$trigger actions= ./>


So you can use the tag: test to switch the action on / off. 

have fun!

PS: Be sure to BACKUP - BACKUP  - BACKUP 
PPS: The preview-pane will trigger the actions!!!

vpl,

You need to delve into the link catcher widget 
. You can then add actions 
(ideally conditional) , perhaps designing it to happen with a particular 
modifier key (not ctrl) pressed at the same time as a click. You could try 
and intervein in the core process, but if you are happy to generate a list 
of tiddler links that have their own link catcher and matching additional 
actions it would be safer and easier.

[vpl]

Hi

Thanks a lot for your answer
In fact I have a tiddler containing different fields that I use in 
different macros
I've successfully added a "Reset" button that reset all my fields to the 
default value
What I'm looking for is a way to avoid this "manual" reset operation and 
trigger automatically the macro when the tiddler is invoked from the home 
tiddler for ex (via a link) or from the search button.

So I suspect that internally tiddlywiki has a mechanism to invoke macro at 
that time, but I cannot find it

Thanks again for your support

Regards

Hi vpl,

Action-widgets are only activated, if a "user-action" happens. So mainly by 
clicking a button, radio- and checkbox-widget, keyboard-shortcuts and so 
on. 

You would need to modify the "edit-button". ... But why do you need this?
