It would be nice if a org.scijava.widget.Button could<br>
be disabled (e.g. grayed out) and enabled in the UI parameter<br>
harvesting dialog (from within some @Parameter callback) if the<br>
current parameters do not allow its action.<br>
<br>
This seems different from the problems associated with dynamically<br>
changing parameter number and/or properties [1], as no reconfiguration<br>
of the UI is required beyond a redraw. The widget should still be<br>
displayed, only its status toggled (one could e.g. add the enabling<br>
condition to the description/tooltip to give the user a hint).<br>
<br>
Does this sound reasonable or should such a feature be included in tracker issue 42 [1]?<br>
<br>
cheers,<br>
