[mapguide-users] Custom layouts...

[Ryider Grey]

Hello Jason,

my name is dimy and I noticed that you received the following message from Alain last year. Were you able to get his example to work? If so I would like to know how you handled the following. I am having some trouble.


"The reference to the AJAX viewer in the legend control code was hardcoded. I 
changed this and I will submit the change to the mapguide trunk shortly. The 
reference to the legend control from the AJAX viewer is hold by a variable 
so all needs to be done is changing the content of this variable to point to 
the new control." 

Do you know which reference to the legend control should be changed and which content variable should be changed as well/

Thanks so much for your help,
Dimy

Jason, 

I attached a couple HTML pages that show you a possible approach in 
displaying the legend control in another place In this example the legend 
control runs in an IFrame at the right of the viewer (see screen snapshot 
below 

This approach requires no code change in the template files. The main issue 
is that the legend control and the viewer call each other, the viewer to set 
the scale as the map is navigated, or to refresh the control among other 
things, and the legend control to change the visibility of layers and 
groups. When the frame hosting the control changes, the way the control and 
the viewer reference each other in the code needs to change as well. The 
reference to the AJAX viewer in the legend control code was hardcoded. I 
changed this and I will submit the change to the mapguide trunk shortly. The 
reference to the legend control from the AJAX viewer is hold by a variable 
so all needs to be done is changing the content of this variable to point to 
the new control. 

The sample script legendpane.html shows you how to wait for the map to be 
fully initialed, create a new legend control (not the new parameter MAPFRAME 
to the LegendCtrl.php request), and when this control is fully initialized, 
sets a reference to it in the AJAX viewer. From that point on the AJAX 
viewer will interact with the new control. 

The drawback of this approach is that the initial legend control is still 
there, only not visible. But its not a big deal, the control is inactive 
after you attached the new instance to the AJAX viewer. The advantage of 
this approach, which to my opinion far outweighs the drawback, is that it 
requires no change in the existing surround. 

Alain
