Closing tabs without opening a new one

[Matt Groth]

I would like to implement a function into my TiddlyWiki in which clicking on an already-opened tab closes it. I'm kind of stuck and was wondering if I could get some advice. Or if someone has already done this let me know. :)

As far as I understand, I need to send a message to $:/state/tab/sidebar (or whatever state) to delete its content if it matches the tab that was just clicked. The problem is I am having trouble figuring out where the code is that defines what actions are taken when the user clicks a tab.

Hi Matt

It sounds like you’re getting into TiddlyWiki quite deeply now :)

As far as I understand, I need to send a message to $:/state/tab/sidebar (or whatever state) to delete its content if it matches the tab that was just clicked. The problem is I am having trouble figuring out where the code is that defines what actions are taken when the user clicks a tab.

Good stuff; your reasoning about the use of the state tiddler is correct. At the moment, clicking on a tab sets the state tiddler to the title of the tiddler holding the content of the tab. You’ll need to add a condition, clearing the state tiddler if it is already set to the current tab.

The core “tabs” macro is defined in this tiddler:

http://tiddlywiki.com/#%24%3A%2Fcore%2Fmacros%2Ftabs

The tiddler appears blank in view mode; click the edit button to see the content.

Now, the change you want to make actually goes pretty deep; it touches the most fundamental part of the logic of the tabs macro: what happens when you click on a tab. Making the change requires understanding how the tabs macro currently works. I’m afraid I don’t have time right now to code it for you; if nobody else here steps up, you might have to figure it out yourself by studying the existing code.

Best wishes

Jeremy

Hi Jeremy, 

I'm starting to use TiddlyWiki for many different purposes. I've found so many great resources, so I'm learning fast!

With your help, I accomplished my goal by implementing the reveal widget and made a pull request. :)

While I have you, could you take a look at my other question? I'm dying to understand how the local repository is implemented in my server.

All the best,

Matt
