[mapguide-users] Legend Group/Layer Display

[Sara Makarenko]

Thank you for your feedback. We'll enter a defect. I propose the simple
fix at this time - the group name will stay visible even when all its
child layers/groups are set to not show in the legend. The group icon
will remain as the folder.

Note that the basic MapGuide behavior of making a layer disappear from
the legend when the layer is not within the scale range will remain the
same. And if all layers beneath a group disappear in this way, the group
will disappear as well.

If you want the MG 6.5 behavior of changing the group icon to resemble a
layer and showing the first layer below, please submit an enhancement
request.

Thanks,
Sara

I agree with your comments.

The current MapGuide 6.5 behaviour of showing the style of the top-most
layer as the group's style is annoying and in many cases misleading to
the user.  In a future release, I would like to see the ability to show
the legend of specific (author-selected) layers within the group as the
group's legend, while hiding other layers.

What I'm seeing is that if all layers under a layer group have "Layer is
visible in the legend" unchecked, then the layer group name does not
show up in the viewer legend.  The layers still draw on the map,
however.  The users just need to be able to see the layer group in the
legend and be able to toggle it on/off.  How it appears to the user is
another issue.  Just having it appear as a group name with no layers (or
sub-groups) visible below it would work for me.  I think it would be
hard to display it any other way since there might be several kinds of
layers underneath of it.

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,
