Script widgets: How to emit a message than can be managed in widget's script?

[stam]

Hi all,

Does anyone know how to emit a message from a script widget that can be captured in the widget's script?
By this I mean emitting a message like 'textChanged' in text fields - where you can then edit the widget's code in the IDE to respond to the message?
Does anyone know if this is possible?

Many thanks

Do

Code: Select all

send "textChanged" to the owner of me

in the script widget script

Thanks Ali

I'm doing that already but was asking if it's possible to respond to the message inside the widget instead of it's owner, pretty much like textChanged would function in a field's script... I'm guessing no then

Wouldn’t that just be calling the handler directly? Are you wanting to do some work in the widget before passing the message for possible additional work outside?

No it's not the same.
If a certain action occurs, then a message would be emitted that can be captured by a developer in the widget's script to react to It,
As mentioned, the best analogy would be implementing a 'textChanged' handler in a text field. It is more practical to have this in the text field's script rather than the card script.

What Ali recommends is what Bernd recommended to me previously and what I've already implemented, and certainly works.
But you have to capture the message in the card script rather than the widget's (i.e. after adding to a card), which is like having a textChanged message in the card script that has to act based on the id of the text field that emitted the 'textChanged' message and the content of the message.
It works, but it's not the most practical/intuitive way of doing this...

But sounds like this probably isn't possible at present

Ok, I understand now. You want an equivalent to the LCB

Code: Select all

post “messageName”

This isn't the intention- you are supposed to be able to handle the message in the widget object's script. I'll have to check but potentially this is a dp 5 bug which will be fixed in dp 6.

Please ignore my previous statement - completely my error.
While I had been handling the message in the card script perhaps misunderstanding Bernd's advice, I've finally had some time to check (day job getting in the way!) and it works perfectly in widget's script. I even get the option to add the handler from the left sidebar in the SE!
Loving script widgets even more!
