1. Assume you have a list of 14 entries
2. The entries are given through a filter like [range[1, 14]]
3. It is desired to display three entries all the time
4. A next button shows the next three entries
1. If pressing next button several times and you reached the end of
list the last three entries are shown!
5. A prev button shows the previous three entries
1. If pressing prev button several times and you reached the
beginning of list the first three entries are shown!
6. So, always, any time three entries are visible on the screen
Question
How to do this?
Partial solution, not works!
\define test(filter:"[range[1,14]]")
<$vars filter=<<__filter__>>
last-item={{{ [list[stateTid]last[]] }}}
first-item={{{ [list[stateTid]first[]] }}}
stateTiddler="stateTid"
>
<$button>Prev List
<$action-setfield $tiddler="stateTid" list=""/>
<$action-listops $tiddler=<<stateTiddler>>
$subfilter="[subfilter<filter>allbefore<first-item>last[3]]
~[subfilter<filter>first[3]]"/>
</$button>
<$button>Next List
<$action-setfield $tiddler="stateTid" list=""/>
<$action-listops $tiddler=<<stateTiddler>>
$subfilter="[subfilter<filter>allafter<last-item>limit[3]]
~[subfilter<filter>last[3]]"/>
</$button>
</$vars>
\end
<<test>>
{{stateTid!!list}}
- Create a tiddler in https://tiddlywiki.com/prerelease/
- Copy paste the above code and click on buttons
- It works but in two cases it show two entries NOT three
Any idea? AND if a simpler solution exist?
