[Gvsig_english] jython-Console line in gvSIG... Usable at all?

[Jorge Sanz]

Hi Wolfgang, 

there is a scripting intro tutorial but at this time only in Spanish :(

http://www.gvsig.gva.es/fileadmin/conselleria/images/Documentacion/descargas/manuales/gvsig-1_0-scripting-tutorial-v2-es.zip

If you (or anyone) feel brave, you can try to download it (as it comes with nice examples) and try to "inspect" the code and the manual to learn a little bit about gvSIG scripting capabilities.

Just for fun, I will paste a simple lines to show the attributes of the first feature loaded into a view with only one vectorial layer. You can try it if you want, just open a new gvSIG view, add a shapefile (for example), open the scripting console and paste line by line. On the examples you will find how to define a GUI, use functions, etc etc. This is just dumb python code:

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
#import gvSIG functions
from gvsiglib import *

#get the view, the mapcontrol and the mapcontext
view = gvSIG.getActiveDocument()
mctrl = view.getMapControl()
mcon = mctrl.getMapContext()

#print the number of layers of the view
print mcon.getLayers().getLayersCount()

#get the first layer and print its name
lyr= mcon.getLayers().getLayer(0)
print lyr.getName()

#finally, get the recordset (attribute table) associated with the layer, print the number of features (rows) and print the first row
rc = lyr.getRecordset()
print rc.getRowCount()
print rc.getRow(1)
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

Immediately you will discover that the console has auto-completion so you can start "hackin" to go inside gvSIG classes. 

Soon we will have more infrastructure to post that kind of "source bits" and little "how-to's" to show how to accomplish scripting and general development tasks.

Best Regards
