Action on tab opening

[Danielo Rodríguez]

Hello again,

It's noticeable that I'm around here again, lots of threads about small questions that are almost impossible to find using the group search.

I know this has been discussed sometimes, but it was a while ago and make it is now possible.

What I want is to dispatch a message when a tab it's opened. In an ideal world it would be enough to just put an action widget inside that tab, but something makes me think that it will not work that way.

Any idea?

Thanks!

Hi Danielo,

 

What I want is to dispatch a message when a tab it's opened.

Do you mean "call a web-service"?

 

In an ideal world it would be enough to just put an action widget inside that tab, but something makes me think that it will not work that way.

I would think there would have to be a widget to dispatch messages, which can be called e.g. via the button widget. Then there would have to be a way to extend the core tabs macro so that clicking a tab will trigger a set of action widgets, as you can do with a generic tab, some parameter perhaps universally called $action which points to a template defining the actions being run.

Best wishes,

Tobias.

Hello Tobias

No I mean a TW message, like the ones dispatched by the button widget or the action-sendmessage widgets. For example tw-new-tiddler

Of course a widget would be necessary to dispatch the message. Currently action widgets are limited to be inside of button widgets. It would be ideal if you can add a widget to the body of a tiddler, and when you navigate/open that tiddler (no matter if it is following a link or opening a tab) the action widget is executed. As I said, I think that someone did something of this kind, but I didn't found it.

The tabs are buttons. So just change the tabs macro and add the action widget. So if someone clicks the tab, the action is activated.
If you want to set some parameters within the tiddler, use text references. ..

just some thoughts. no tests made.

...you could use the Tab-state-tiddler for a reveal-function. That is no modal but at least something.

Hello Jan.

Thank you for the tip, but what I need is to trigger an action, in this case sending a message

I hadn't realized this. Very good to know! Thanks PMario.

Simple test here.

Hello Mat,

thank you for your example.
I ended with something similar for another implementation.

My requirement for what I originally asked here does not allow me to change or override any core macro, so I can't implement my own tabs.

I still thinking we need a widget that acts on loading

[Jed Carty]

A widget that acts on loading can put you into an infinite loop very easily. I made a plugin that triggers a set of action widgets on a change to the wiki. You can set what happens and what change is listened for. It isn't polished and the documentation is terrible, but here it is.

Thanks Jed,

I'll check it out
