Subject: [Ym4r-user] can't define custom GIcon
Message-ID: <529247150710160851y24b8f0d9jd0189636de8ca9de@mail.gmail.com>

Hi,

I am having trouble getting custom GIcons to display.  Here is the code in
my controller:

    @map = GMap.new("map_div")
    @map.control_init(:large_map => true,:map_type => true)

    @map.icon_global_init(GIcon.new(:image => "images/APBox-20.png
"),"ap_none")
    infoString = "Friendly Name: "+result.friendly_name+
                    "<br/>MAC: "+result.mac.to_s+
                    "<br/><br/><a href='/stats/table'>Table View</a>"


        marker = GMarker.new(latlng, :info_window => infoString, :icon =>
"ap_none")
        point = GLatLng.new(latlng)
        @gmap_markers << marker

    @map.center_zoom_init(bounding_box_center(@gmap_markers), 15)
    @map.overlay_global_init(GMarkerGroup.new(true, @gmap_markers),"NOI")

In my view I simply have:

<%= @map.div(:width => 600,:height => 400) %>

When I don't define the :icon property in the GMarker constructor,
everything works properly.  When I do, the map loads, but the marker isn't
displayed, and none of the map controls appear either.  The error I am
getting in Firebug is:

b has no properties.

The error occurs on this line:

z.prototype.rb=function(){var a=this,b=a.ta.iconAnchor,c=a.Zc=a.c.h(a.F),d=
a.Th=new n(c.x-b.x,c.y-b.y-a.Z),e=new n(d.x+a.Z/2,d.y+a.Z/2
);return{divPixel:c,position:d,shadowPosition:e}};

which is line 805 in main.js.

Has anybody else experienced this problem, or see what I am doing wrong?
Any help would be appreciated.

Thanks,

Simon

Looks like you haven't provided all of the information for your icon in your
@map.icon_global_init

 @map.icon_global_init(GIcon.new(:image =>
"/images/icon_construction.png", :icon_size =>
GSize.new(15,15),:icon_anchor => GPoint.new(7,7),:info_window_anchor
=> GPoint.new(9,2)),"icon_construction")

is the example @
http://thepochisuperstarmegashow.com/2006/06/03/google-maps-yahoo-traffic-mash-up/

I ended up having issues and just defined the icons using javascript
in the typical google maps fashion.

This error usually occurs when you try to use a GMap before you have
centered it. Annoying 'bug' or need to initialize in GMap.

by the way, have you tried the YM4R_Mapstraction? :)

Thanks, I added in the missing attributes (didn't realize all were required)
and that seems to have solved the problem.  Custom icons are now being
displayed nicely.

I do have another question now:

I am trying to set the zoom level of the map dynamically based on the
markers that I am adding to it, so that all of the markers will be visible.
Here is what I am trying:

@gmap_points = Array.new

latlng = Array.new
latlng[0] = latitude
latlng[1] = longitude

@gmap_points << latlng

@bounds = GBounds.new(@gmap_points)
bounds = Variable.new(@bounds)

@map.record_init('map.setCenter(bounds.getCenter(),
map.getBoundsZoomLevel(bounds));
')

So I am trying to create a GBounds object with my array of points, and then
bind it to a javascript variable so that I can pass in the appropriate
javascript code into the onLoad function.  This seems to be working ok, as
this is the javascript that gets output:

window.onload = addCodeToFunction(window.onload,function() {
if (GBrowserIsCompatible()) {
map = new GMap2(document.getElementById("map_div"));
map.addOverlay(NOI);
map.setCenter(bounds.getCenter(), map.getBoundsZoomLevel(bounds));
map.addControl(new GLargeMapControl());
map.addControl(new GMapTypeControl());
}

But I am getting this error:

this.v has no properties

on line 611 of main.js.  Looking at the code above the onload
function, I can't see the bounds variable being declared
anywhere, so I think this might be the issue, but I'm not sure why it
isn't working.  Can anybody see where I may have made a mistake,
or has anybody else implemented this functionality using ym4r successfully?

Thanks again,

Simon

Subject: [Ym4r-user] GMarkerGroup center_and_zoom_on_markers problem
Message-ID: <529247150710170807x1c6a6339nfd0c6758212179b2@mail.gmail.com>

Hi,

I found the funcitoned mentioned in title (center_and_zoom_on_markers) but
am having troubles getting it working.

I have several markers being added to an array (@gmap_markers = []) in the
following manner:

marker = GMarker.new(latlng, :info_window => infoString, :icon => my_icon)
@gmap_markers << marker

I am then trying to do the following:

group = GMarkerGroup.new(true, @gmap_markers)
@map.overlay_global_init(group,"NOI")
@map.record_init group.center_and_zoom_on_markers

But I get the following error: this.v has no properties (on line 611 of
main.js, according to Firebug).  If I replace the line "@map.record_init
group.center_and_zoom_on_markers" with
"@map.center_zoom_init(bounding_box_center(@gmap_markers),
9)" everything works as expected.  bounding_box_center is just a function I
wrote quickly to get the center point of the group of markers.

Has anybody else used the center_and_zoom_on_markers method successfully?
I'm not sure what the problem is, as I think I am using it correctly.  Any
help would be appreciated.

Thanks,

Simon
