Hi all,
while migrating a (quite big [1]) qooxdoo 0.7.5-pre based application I am
currently facing a generator problem:
<code class="text">
>>> Resolving dependencies...
- ! Unknown class referenced: google.maps.Map2 (in:
infodesk.gis.mapprovider.Google)
- ! Unknown class referenced: google.maps.LatLng (in:
infodesk.gis.mapprovider.Google)
- ! Unknown class referenced: google.maps.LatLng (in:
infodesk.gis.mapprovider.Google)
- ! Unknown class referenced: google.maps.Point (in:
infodesk.gis.mapprovider.Google)
- ! Unknown class referenced: google.maps.LatLng (in:
infodesk.gis.mapprovider.Google)
- ! Unknown class referenced: google.maps.LatLng (in:
infodesk.gis.mapprovider.Google)
- ! Unknown class referenced: google.maps.LatLng (in:
infodesk.gis.mapprovider.Google)
- ! Unknown class referenced: google.maps.LatLngBounds (in:
infodesk.gis.mapprovider.Google)
- ! Unknown class referenced: infodesk.gis.mapprovider(in: infodesk.gis.Map)
</code>
The generator complaining about unknown references to a class, that is loaded
at runtime. In my case it's googles maps api. ("infodesk" beeing our
applications main namespace here.) I am loading the maps API via googles
api-loading mechanism (see [3] for details if you like ;) ) to keep it under
it's own "google" namespace by including a
<code class="html">
<script type="text/javascript">google.load("maps", "2", {"language" : "de",
"other_params":"client=CLIENT&sensor=false&channel=GOOGLE_CHANNEL_ID"});</script>
</code>
line in my main loader HTML file.
In the "0.7.4-makefile" I just had to tell the 'lint' target about this by
setting the LINT_ALLOWED_GLOBALS setting, 'build' and 'api' targets did not
complain about unknown class/namespace at all.
Currently I still have some way to go until I'm migrating that class
(infodesk.gis.mapprovider.Google), but I don't like to start with errors and
warnings while not even beyond checkpoint 2 of this [2] guide... ;)
The class "infodesk.gis.mapprovider.Google" looks something like this:
<code class="javascript">
qx.Class.define("infodesk.gis.mapprovider.Google",
{
extend : infodesk.gis.mapprovider.AbstractMapProvider,
implement : infodesk.gis.mapprovider.IMapProvider,
/**
* @param container {qx.legacy.ui.layout.CanvasLayout} Layer, the map
* should be displayed
*/
construct : function (container)
{
this.base(arguments, container);
container.addListener("appear", this.__onAppear, this);
if (container.isSeeable()) {
this.__createMapInstance();
}
},
// ...
members :
{
/**
* Create the google maps instance and store it at the {...@link #__gmap}
* member.
*
* @type member
* @return {void}
*/
__createMapInstance : function ()
{
if (this.__gmap == null)
{
if (typeof google == "object" && typeof google.maps == "object") {
this.__gmap = new google.maps.Map2(this._container.getElement());
} else { // Loading of API failed!
throw new Error("could not create google API object!");
}
}
},
// ...
},
destruct : function ()
{
this._container.removeListener("appear", this.__onAppear, this);
this._disposeFields("__gmap", "__zoom", "__center");
// This should reduce the memory leaks on IE (see
// http://code.google.com/apis/maps/documentation/index.html#Memory_Leaks
// for details):
google.maps.Unload();
}
});
</code>
Any help or enlightenment for me?
Cheers Peter
P.S.: Yes, I've read [4], [5] and [6] but still no luck! ;)
And hopefully the word-wrapping did not ruin all the "inline" code
