I have a more-general mechanism in CellProfiler that lets you do
this kind of thing. The module (read ImageJ plugin) has a method
that returns a collection of settings. These are equivalent to the
parameters in ImageJ 2.0. You can restructure the collection
contextually in response to user events - for instance, there's a
"DoSomething" setting which is displayed as a button and it calls a
callback when the button is pressed. You can implement an "Add
another" button that changes the module's setting list in the
callback and the framework will ask for the settings again, with the
settings added by pressing the button.<br>
<br>
CellProfiler 1.0 had a fixed list and it felt like it was
arbitrarily limiting - you'd run into cases where you wanted four of
something, but provisions were there for only 3 slots.<br>
<br>
IMHO, unfortunately pretty far down the line to change the way this
works, but you could convince me otherwise.<br>

In regards to the proposal note that I see that the issue is more
than just allowing us to populate choices and min/max at runtime.
In the ReorderAxes plugin I'd like to have 3 parameters each of
which has 3 choices for an XYZ Dataset. And 5 parameters each with
5 choices for an XYCZT Dataset. So I should be able to specify the
number of parameters at runtime also. Or make the plugin have the
max possible but only enable and display/use a subset of the
parameters present.<br>

Hi Grant, Barry et. al,<br>
<br>
At the meeting today we discussed how there is currently no
way to override an annotated parameter's min, max or choices
settings. It would be nice to be able to set them based on the
current state upon plugin execution.<br>
<br>
One way is to have option callback methods for min, max and
choices. So rather than a constant value, the min, max and
choices are computed by a method dynamically. For min and max,
there could be a notation like putting "#" in front of the
string to indicate it's a callback, since min and max of
Parameter are already strings. For choices, it's a String, so
you'd have to write it as: 'choices = {"#nameOfCallback"}'.<br>
<br>
Do you think that's too awkward? Anyone have any better ideas?<br>
