Re: [udig-devel] Get feature on mousePressed method
|
There is also an example tool in the tutorial code examples project that
goes through all the layers in z order and does a query on each one
returning the first feature found.
Once you get your feature you have a couple ways of modifying it:
- use an edit command (so the change can be in the undo/redo queue)
- use the featurestore API and call modifyFeatures method. To do this
you will need a filter to select the feature (use FeatureID filter to
select a single feature) and the name of the attribute to modify and the
new value

A feature source can take a filter so instead of asking for all
features [source.getFeatures()] you can make a filter and only ask for
features within that filter [source.getFeatures(myFilter)].
I believe the context associated with your tool should have a
getBoundingBox(...) function that should return a bounding box around
where the user clicked. You can then use a FilterFactory class to
create a filter.
Have a look at the info tool; it sounds like you are doing something
similar.

Hi uDig'gers!
I have a Class that extend AbstractEditTool.
I need to get the feature selected by clicking on the map, in the
method mousePressed of my class so that I can modify its attributes.
I have worked on the following code
IMap map = ApplicationGIS.getActiveMap();
FeatureSource
source=map.getEditManager().getSelectedLayer().getResource(
FeatureSource.class, new NullProgressMonitor());
FeatureCollection collection=source.getFeatures();
But it retuns all the features on Selected layer and not the 'Clicked'
single one.
