Re: [tw] Background color from color palette

[stevesuny]

Jeremy et al thanks! This almost worked as proposed, but I figured it out. 
I was having trouble getting the "#" into the field value.

Here is the working macro, currently implemented at DesignWriteStudio 

 (this 
is for a class I am teaching this semester at SUNY Polytechnic Institute). 
I had to do some odd dancing around in the defines to get the "#" to show 
up in the background-color field.

Questions now: 

<1> on phone, the "prev" and "next" buttons are not properly displaying; 
too far over to the left
<2> I'd like to set the slidenum field to be the same name as the 
"slidetag"  -- so that a given tiddler can be used/ordered in multiple 
slideshows. That would require a transclusion of some sort that I haven't 
begun to figure out. 
<3> I'd hope to be able to color the slide in the same  as displaying 
the slides, but that may not be possible? As you can see, I run through the 
slides on a  twice: once to set the bg color, once to open into the 
story river.

And I hope to bundle this as a plugin (soon).

Thannks!

//steve.

(macro code follows)








\define bgcolor() {{$:/palettes/DWS##$(slidenum)$}}
\define bgcolor2() #$(rgb)$
\define punchshow(slidetag)




<$set name=slidetag value="$slidetag$">



<$button set="$:/state/sidebar" setTo="no" 
tooltip={{$:/language/Buttons/HideSideBar/Hint}} 
aria-label={{$:/language/Buttons/HideSideBar/Caption}} >

Re: [tw] Background color from color palette

[Jeremy Ruston]

Hi Steve

Untested, but try this:


<$list filter="[tag!sort]">
<$vars slidenum={{!!slidenum}}>
<$wikify name="rgb" text=<>>
<$action-setfield background-color=<>/>




Given that you’ve got a transclusion in the variable ‘bgcolor’, the wikify 
widget is simply rendering that transclusion, ie converting it into the 
underlying value.

Best wishes

Jeremy.
