Re: [tw5] Re: controlling the background image

[FFT]

after adding the field name bg, what is the syntax for the next part 
"...containing the name of an image tiddler"?

 Greetings Tiddly Wickers,

 I want to implement something in TW and I'm not at all sure how to do 
 it.

 The goal is, when a tiddler is added to the story, if it has a field 
 "background" with the name of an image tiddler, the page background would 
 get set to that image. Possibly another fieldwork (backgroundoptions?) 
 could specify span, cover, scroll, and such.

 I had originally thought it could be done when a tiddler becomes the 
 current tiddler, but Jeremy mentioned TW doesn't have a notion of the 
 "current tiddler' in the sense of the tiddler that is currently being 
 viewed. He mentioned the core Dynannotate plugin, but I'm hopeful to avoid 
 that level of complexity.

 The specific trigger isn't important to me, as long as when the end 
 user clicks around and opens tiddlers, the background can be changed on a 
 per-tiddler basis.

 What do you think?

 Thanks!
 -Paul

Thank you, Eric.

That is precisely what is needed, and it works flawlessly.

Kind regards,

Re: [tw5] Re: controlling the background image

[Eric Shulman]

Try this:
Create a new tiddler (e.g., "SetPageBackground"), tagged with `
$:/tags/Stylesheet`, containing:
```
<$let curr={{$:/HistoryList!!current-tiddler}}>
body.tc-body {
background-image:url(<$macrocall $name="datauri" title={{{ [get[bg]] 
}}} $output="text/plain"/>);
background-size:{{{ [get[bgsize]] }}};
}

```
Then, in any tiddler, added a field named "bg" containing the name of an 
image tiddler,
and optionally, a field named "bgsize" containing desired CSS 
`background-size` attributes (e.g., "cover", "auto auto", "100% auto", 
etc.).  When that tiddler is navigated to (by clicking its link in the 
sidebar or from another tiddler), the specfied "bg" image (and bgsize 
attributes) will be applied to the `body.tc-body` background.

See https://developer.mozilla.org/en-US/docs/Web/CSS/background-size for 
valid "bgsize" values.

Note for GoogleGroups: do not include the single or tripled "backticks" 
when entering the tag or tiddler body text.  Those are only entered here to 
provide formatting for this response when displayed in 
https://talk.tiddlywiki.org/

enjoy,

Re: [tw5] Re: controlling the background image

[Paul Reiber]

Hi Scott,

For the typical end user browsing experience, I think "whichever tiddler is
opened most recently" would work fine.

I can imagine situations where a single-tiddler story would be preferable,
but my hope is that it wouldn't be required.

I'll check out talk.tiddlywiki.org and if this doesn't get traction here in
the google group I'll follow up over there.

Thank you!
-Paul

[tw5] Re: controlling the background image

[Scott Sauyet]

(Note that most of the discussion for TW is being held 
at https://talk.tiddlywiki.org/.  You might get more response there.)

One question: Are  you using a story view that opens just one tiddler at a 
time?  If not, what's your expected behavior when there are multiple 
tiddlers open with `background` images?
