two ways to do things in a button

[Joe Armstrong]

I wrote this code to do two things when you click on a button - it adds a tag and closes the sidebar

<$fieldmangler>

<$button>

<$action-setfield $tiddler="$:/state/sidebar" 

text ="no" /> 

<$action-sendmessage $message="tm-add-tag" $param="wow"/>

   Add  tag `wow` and collapse the sidebar

</$button>

</$fieldmangler>

It works fine - but when I wrote it felt strange.

I looked for but could not find an action-sendmessage that sets the field of a tiddler

I'd kind of expected to find

something like

<$action-sendmessage $message="tm-set-field" $tiddler="$:/state/sidebar" text="no" />

Which would make the body the button easier

to understand.

My mental model of a button is something

that when you press it sends messages to different parts of the system, causing things to happen. 

Can't everything be done with messages?

Cheers

Hi Joe

There’s an <$action-setfield> widget which allows values to be assigned to fields:

There’s also an <$action-listops> widget that allows a field value to be modified (e.g. adding or removing a specific entry from a list):

Best wishes

Jeremy
