Hi Tim,
Let me see if I've understood what are you doing. You need to:
-Create (or modify?) a LBCGoogleMap when a ListBox changes
-Render or update the LBCGoogleMap when a Button is clicked.
You said LBCGoogleMap is not a WAComponent, what it is? If it's a
SFObject, then you can add to your SearcherInterface sending as
argument of #addSubpane: message, as already knows how to answer
#name (remember, it must answer #name properly, that is, not the #name
method in Object).
Then you can have:
>>initialize
....
self addSubpane: self map
...
>>map
^LBCGoogleMap new
name: 'mapDisplay'; " configure the mapDisplay's name"
setCenter: model coordinates zoom: model zoom;
addControl: GControl largeMapControl;
setUIToDefault;
yourself.
If when the list changes, you have to re-create the mapDisplay, in the
#regionSelectionChanged "callback" (the message sent when the list is
#changed) you should replace it as follows:
oldMap := self paneNamed: 'mapDisplay'.
self replacePane: oldMap with: self map
And to refresh properly the mapDisplay it should be rendered inside a
tag with id equals to its styleId, like this:
LBCGoogleMap >>renderContentOn: aRenderer
aRenderer div
id: self styleId;
with: [ "render your component" ]
and must answer #refreshOn: (please see #when:send:to:refresh: section
in http://wiki.squeak.org/squeak/6093). You can implement it this way:
refreshOn: aRenderer
"Support for the events"
self renderContentOn: aRenderer
You will need to preserve the same #styleId, to do this simply send
the message styleId: 'anyId' to the mapDisplay. Another way to solve
this is adding a SFPanel which contains the mapDisplay and refresh it
when the button is clicked.
Regards
Juan M.
