[mapguide-internals] Potential legend enhancements (was RFC 50 -Hide Legend Styles)

Hi Jason,

I don't know whether MG legend definition is constrained by certain
standards, but you may consider switching to custom solution as I did (early
screenshots follow):

Yes, I'm working on some municipal solution too (spatial and zoning plans,
cadastre, etc). It requires a bit different approach on displaying thematic
layers since "thematic" part is very stretched term here :-) as each spatial
plan has it's own thematic setup users are not allowed to change. BTW, my
solution was initially designed for POI terminals so it had to follow
specific UI scenarios.

If you still want to go down MG/Fusion way, you may consider displaying
spatial/zoning plans coverage first, then when specific plan (polygon) is
picked it should display it's contents. Specific thematic maps get displayed
based on consecutive menu picks.

Regards,
Maksim Sestic

Heh.

Along those lines, I've been thinking a bit about the current legend
usability.  I'll be putting these in as enhancement requests, but thought
I'd ask for feedback first:

- Add a new setting to allow the layer to be displayed in the legend without
the check box next to it.  This allows the theming to be shown, but does not
allow the layer to be turned on/off.

- Add the ability to define an external resource for a folder or layer icon,
and allow it to be hidden it entirely.

I have a couple motivations for this:

1. Some layers (like the layers comprising our official community plan) can
not be displayed or turned on/off in isolation for legal reasons.
As such, I have had to put them all into a single folder, and not display
any of the individual items in the folder.  This would be much more useful
from a user perspective if I could turn off the folder icon, display the
folder as a name with a check-box, and have each of the layers shown
underneath without the checkboxes so the user can see what the theming
means.

2. Some features pull data from different layers based on scale range.
In my case, orthophotos pull data from a single layer at one level, and
multiple layers at another. Currently, I am dealing with these by placing
them into a folder and hiding all of the layers, but it would be nice to be
able to change the icon for the folder (to a camera?) so that it looks like
a layer rather than a folder.

Any thoughts?

Jason

The motivation is not from Studio as Studio cannot do anything about the
issue. You have to use the web tier test pages to grab the XML/edit it/ then
save it back - I wish Studio could do this for you now, but it cannot.

The motivation is so that the layer definition doesn't have to have style
information removed/added whenever you would like to alter the appearance of
the legend.
