$linkcatcher widget, need an example

[Mohammad]

I am using $link to create some links using $list widget!

I want to save the title of clicked item in a temporary tiddler for further processing. We know the $link widget does not supports actions

How can I do this?

<$link to=<<currentTiddler>>><$text text=<<currentTiddler>>/></$link>
<$linkcatcher actions="""<$action-setfield $tiddler=<<tidSelectedItem>> text=<<currentTiddler>> />""" />

here the tidSelectedItem is a variable refers to my temporary tiddler to keep the title of clicked item

I found the solution

It seems the $linkcatcher  catch the link action so, if one needs to navigate shall pass a message to $linkcatcher

The logic is a bit confusing

Example

• link and navigate to clicked title
• capture the title of clicked item and store in my tiddler given through a variable

<$linkcatcher set=<<tidSelectedItem>> setTo=<<__item__>> message="tm-navigate">
<$link to=<<__item__>> overrideClass=<<openItemClass>> >
  <$view tiddler=<<__item__>> field="caption">
    <$view tiddler=<<__item__>> field="title"></$view>
  </$view>
</$link>        
</$linkcatcher>

Remarks

• a link to item is created (item holds a title is given through macro input parameter
• a proper form of caption/title is shown using $view widget
• on click linkcatcher use the tm-navigate to navigate to tiddler its title is given by item
• the title of clicked item is stored in a temporary tiddler (tidSelectedItem holds the title of temporary tiddler)

How about using a $button instead of the $link widget?  Something like this:

\define showlink(item)
<$tiddler tiddler=<<__item__>>>
   <$button class="tc-btn-invisible">
      <$view field="caption"><$view field="title"/></$view>

      <$action-setfield $tiddler=<<tidSelectedItem>> text=<<currentTiddler>>

/>
      <$action-navigate />
   </$button>
</$tiddler>
\end

Note: I used the <$tiddler> widget to set the <<currentTiddler>> to the <<__item__>>.  This is just so the $view and $action-navigate widgets can use their default parameters for $tiddler and $to

Tony,

 I will post some examples and will need your review. I found it confusing and worth to prepare some examples!

I hope other also share their thoughts.

Best wishes

Many thanks Eric. This is a great solution.

In my opinion, the $button here is more clear and semantic and for me is quite understandable.

The issue I have is I cannot drag the link like what I see in Open or Recent tabs in the sidebar and I need to have that feature.

What do you think?

Best wishes

The $button widget has an optional "dragTiddler" parameter for enabling dragging.  For this use case:

 <$button class="tc-btn-invisible" dragTiddler=<<currentTiddler>>>

Yep,

 Thank you Eric!
