Hi everyone,
I am using Version 1.8.0, rev 4164.
In the code of a plugin I am writing I defined a FeatureDataset with an
attribute "number" with integer values from 0 to 2. I added that FD to
a layer. Now I want to style the layer by that attribute. From various
ancient mailing list threads and random guessing I ended up with this:
layer.getBasicStyle().setEnabled(false);
layer.addStyle(new ColorThemingStyle("number",
CollectionUtil.createMap(
new Object[]{
0, new BasicStyle(Color.blue),
1, new BasicStyle(Color.orange),
2, new BasicStyle(Color.red)}),
new BasicStyle(Color.green) //default
)
);
layer.getStyle(ColorThemingStyle.class).setEnabled(true);
layer.fireAppearanceChanged();
This should assign blue to features where the "number" is 0, orange to
those with 1 etc.
When I run this plugin within OpenJUMP, the features in the map are
displayed in a grey color, not the colors I assigned. Once I open and
directly "OK"-close the "Change Styles"-dialog of the layer, the style
I defined in the code is used. So, what am I missing?
I already tried appending this without success:
context.getLayerManager().fireLayerChanged(layer,
LayerEventType.APPEARANCE_CHANGED);
Is this even the right approach? I got it mostly from
http://lists.refractions.net/pipermail/jump-users/2004-August/001352.html
If someone feels generous, I would also be highly interested in a basic
example of using a ranged style. I got as far as knowing that I would
need to use Range but have no idea how to do that or how to apply it.
Thanks, Hannes
