[mapguide-users] Legend Group/Layer Display

[Kori Maleski]

Hi Sara,

"Or are you talking about a situation where all layers in a group are
hidden in the legend (but visible in the map) and only the group name
shows up in the legend. So the group name would have a folder icon. And
users would turn on and off the group with one click (which in turn
would turn on and off all the hidden layers). Is this what you're
wanting?"


That is exactly what I am wanting.

It is a necessary ability to have when you wish to have combined group of
Raster or Vector layers appear as a single Layer, even though they are a
group.

An example:

I have two Road Label Layers - each referencing a separate SDF.
1st SDF appears 0 - 2500 - referencing detailed road segments (segmented at
every intersection) with Labels.
2nd SDF appears 2500 - 30000 - referencing generalized road segments
(segmented at major intersections) with Labels.

Both are in a group called 'Road Labels'.

Utilizing the two different SDFs allows road labeling to appear less
cluttered and more cartographically pleasing.


I want the group to be initially displayed in the map, and visible in the
legend.

I want the layers to be initially displayed in the map, but not visible in
the legend.


Currently MG Open will hide the Group and display the group and its layers
in the map.

I need to be able to toggle that group - like the ability in MG 6.5.


Cheers,

Tell us more about this. MG 6.5 had a feature to make a group in the
legend look like a layer when all layers in the group have legend labels
turned off. It showed a single layer wafer (instead of the stacked wafer
icon) and displayed in the legend the first layer visible in the scale
range. So there could have been multiple layers in the group, but it
would show only the first one visible in that range. Are you talking
about this?

Or are you talking about a situation where all layers in a group are
hidden in the legend (but visible in the map) and only the group name
shows up in the legend. So the group name would have a folder icon. And
users would turn on and off the group with one click (which in turn
would turn on and off all the hidden layers). Is this what you're
wanting?

I agree that this would be a flaw.  I currently do this kind of thing in
several MapGuide 6.5 maps as I only want the user to have control over
the
entire layer group and often want to hide the layers in the legend below
the
group.  I do this often with imagery layers.

I have found one major difference in how the Legend Layer and Group
display
differs from MG 6.5:


I have 2 layers in a group.

I do not wish these layers to be visible in the legend.
I wish these layers to be initially displayed in the map.

I wish the group to be visible in the legend.
I wish the group to be initially displayed in the map.

MG Open
- Displays the Layers in the map
- Does not Display them in the legend
- Does not display the group


MG 6.5
- Displays the Layers in the Map
- Does not Display them in the legend
- Displays the group


This difference in how the Group Display/Visibility works is a large
flaw.

We need to be able to group layers that are visible in the map but not
the
legend within a group that can be toggled on or off.


Any help or input?

Cheers,
