[josm-dev] Plugin for "wifi geolocalization inside building" ...

[Minh Quang]

hi there,
I would like to know how to work with Toggle action. Like I asked you for the filter function, I found the intersesting filter classes (FilterDialog). Now I would like to know if I could change the behavior of this filter action in my plugin. I dont wanna to modify these classes's source code directly, because it's not so clear. Can I override some methods inside FilterDialogs????

Thanks
Best regard

Hi,

I'll give you a few pointers to further information. I you want to 
create a plugin which creates layers, downloads and uploads geo-data, 
manipulates data in the background, etc. you can't avoid to get familiar 
with a subset of the JOSM code base. Read it and write one or more small 
prototypes to get hands-on experience. Nobody on this list can relieve 
you from this burden. If you run into trouble ask again.

* Read the code in org.openstreetmap.josm.gui.layer. In particular, have 
a look at OsmDataLayer. Find out, how an OsmDataLayer is currently 
created in JOSM and try to mimic this in your plugin.

* Read the code in org.openstreetmap.josm.data.osm, in particular 
OsmPrimitive.java, Node.java, Way.java and Relation.java. You'll have to 
manipulate them. Another cornerstone is DataSet.java. That's where your 
inhouse objects will be kept in  JOSM (or your plugin). Each 
OsmDataLayer has a DataSet.

* Have a look at the classes in org.openstreetmap.josm.io. 
OsmServerReader reads geo-data as XML from an input stream and replies a 
DataSet. Want to see it in action? Then have a look at 
org.openstreetmap.josm.actions.downloadtasks.DownloadOsmTask. This is 
also an example on how JOSM currently runs asynchronous tasks.

Are you aware of this page: 
http://josm.openstreetmap.de/wiki/DevelopersGuide/DevelopingPlugins ? 
You should read it too. It gives you additional infos about creating a 
JOSM plugin.

Regards
Karl
