Hi Tobias and BJ,
Thank you both very much for your input. Tobias, that's a great suggestion,
but I don't know enough JavaScript to assign variables with comma
separations. The way it is now you can use multiple remove widgets, one for
each list you want to remove from, for example:
<$remove /> // removes current tiddler from all tag fields
<$remove removeFromField = "list"/> // removes current tiddler from all
list fields
Not the most elegant, I know...
BJ, I made some changes to your taglist widget for this specific
application. I have many tiddlers that have multiple ordered lists, but I
do not necessarily want a unique tag for every ordered list in my program.
Although I suppose that each list does have a unique combination of tags,
and using that would have probably been a better approach.
Also, I added some things in to restrict what tiddlers can be added to what
lists. For example, I do not want users to be able to accidentally drop a
Task into a list of Learning Objectives. Since I am using a fair number of
nested taglists, this has been helpful.
BJ I absolutely LOVE the taglist widget. It is practically the foundation
of my user interface because it makes the program so much more usable. I
don't have the time or the expertise to figure this out, unfortunately, but
if you have the time, do you have any suggestions for the following -- say
I drag a Task tiddler into a list of Tasks in a Lesson tiddler. Both Task
and Lesson tiddlers have lists of Objective tiddlers. Can I add the
objectives of the Task to the objectives of the Lesson? (I can do this with
a button, but it would be awesome if it were automatically done on the drop
event.)
One last thing: don't use that original remove.js -- it can delete things
unpredictably if the listfield of a tiddler is blank or missing! Instead,
use this change to the execute part:
RemoveWidget.prototype.execute = function() {
var defaultFilter;
this.removeThis =
this.getAttribute("remove",this.getVariable("currentTiddler"));
this.removeFromField = this.getAttribute("removeFromField","tags");
if (this.removeFromField == "") { this.removeFromTiddlers = ""} else {
var defaultFilter = "[search:" + this.removeFromField + "[" +
this.removeThis + "]]";
this.removeFromTiddlers =
this.getTiddlerList(this.getAttribute("removeFilter",defaultFilter));
}
};
Thanks for everyone's help,
Patrick
