[mapguide-users] Legend Background Color?

[Alain Lebatard]

Hi Andy,

 

Schematically, the structure is the following:

 

 <MapFrame>

     <LegendCtrl>

        <LegendScript />

        <LegendUI />

     <LegendCtrl>

</MapFrame>

    

LegendCtrl lives in an IFRAME inside the map frame. It's built with
LegendCtrl.php

LegendScript is one of the 2 frames inside LegendCtrl. It's built with
Legend.php. This script returns a Javascript representation of the
legend tree data (no UI, just a structured set of objects representing
layers, styles, etc...). This frame is not visible.

LegendUI is the second frame inside LegendCtrl. It's built with
LegendUi.php. This page is the UI representation of the legend tree data
contained in LegendScript

 

When the legend needs refresh, a Legend.php request is initiated from
LegendCtrl and the LegendScript frame is refreshed with new data tree.
When LegendScript has finished loading, LegendUiFrame content is rebuilt
using this new data structure.

 

Hope this helps...

 

Alain

Subject: [mapguide-users] Legend Background Color?

 

I'm discovering the joys of chasing endless framesets and frames in the
web layout viewer files.  I'm trying to change the background color and
font color for the legend and property panes.  This is easy enough to do
by editing the styles in the legendui.templ and propertyctrl.templ
files.  But this changes the values for every web layout on that server.
I would instead like to set these properties at run-time and I'm having
a heck of a time figuring out the object reference to these frames.  Say
I am starting with the Sheboygan sample and with a JavaScript function
in the ajaxviewersample.php file.  Can anyone tell me what the object
reference to legendui.templ would be?  I tried using the DOM inspector
for Firefox, and that helped some, but I'm still lost in the spaghetti.

Thanks for any help. 

Andy
