[Dynapi-Widgetdev] "Menu" list.js widget fixes

[Alan M. <amu...@ra...>]

Last week, I volunteered (on the help list) to further improve the list 
widget (which I am using as a menu navigator).

I made a few changes and am hoping Robert (or another core developer) can 
check this into CVS.
All my changes are noted with my initials "AM:"

1.  I added the method List.setFont(face, size) to allow a web-developer to 
set a font for the all the list items.

2.  I added a property to List "canDeselectAll" which (when false, the 
default) prevents the user from deselecting the selected item in the 
list.  This property/feature is ignored when in multiMode.  Apart from 
adding and initializing the property, I altered the following list item 
event handler to implement it:
ListItem.listevents.onmousedown = function (e) {
         var o = e.getSource();
         // AM: Prevent the user from deselecting if canDeselectAll is not 
true.
         // Of course multi-mode negates this option:
         if ((o.list.canDeselectAll) || o.list.multiMode || !o.selected) {
                 o.setSelected(!o.selected);
         }
};

3.  I added setFontColor() call in ListItem.setColors().  This is 
essentially a "bug fix".

Apologies for attaching the file (zipped), but I figure that is the easiest 
way to get it to the core developers who can check it into CVS .

To see an example of this list in action (with a very preliminary web 
site), go to:

Please let me know when my changes are incorporated into the current snapshot.

Thanks!

We should really create a style object (there use to be one). This
object would define all the different methods needed to change font
styles. It would also allow for the writing of font strings. Then,
this object could be used by many of the widgets. Most of the widgets
now do not allow the changing of font styles very easily because that
is really the last thing you do once the widgets are stable.

A style object is a good idea, but I am not advanced enough in DynAPI to 
undertake something so generic.
In the meantime, does it make sense to add my changes to the snapshot to 
make the widget more useful?

Nicola pointed out that my menu list fails in NS6.  (Thanks Nicola!)  I 
caught your  message...

Who? When?

I was just looking at this problem because Nicola suggested it is why the 
"menu" list is not working correctly in NS 6.
With some debugging, I can say that Nicola is correct.  The 
setContentHeight() method does not work in label.js

Is someone working on this problem?
Also, Robert, I sent a new version of list.js to the widgetdev list.  Did 
you see it?

Thanks, Alan
