I found an interesting function to use in an add-in called onRectangle. I would like to use this to build a feature set and get values from fields.
Now that I have an extent how do I use it to select a feature or features and then get the values from field1, field2, etc...
def __init__(self): self.enabled = True self.cursor = 3 self.shape = 'Rectangle' def onRectangle(self, rectangle_geometry): """Occurs when the rectangle is drawn and the mouse button is released. The rectangle is a extent object.""" extent = rectangle_geometry
Now that I have an extent how do I use it to select a feature or features and then get the values from field1, field2, etc...
mxd = arcpy.mapping.MapDocument('CURRENT') df = mxd.activeDataFrame ext = df.extent lyrs = arcpy.mapping.ListLayers(mxd, "Stands", df) if lyrs: lyr = lyrs[0] else: return a = arcpy.Array() a.add(ext.lowerLeft) a.add(ext.lowerRight) a.add(ext.upperRight) a.add(ext.upperLeft) a.add(ext.lowerLeft) thepoly = arcpy.Polygon(a) arcpy.SelectLayerByLocation_management('Stands', 'Intersect', thepoly, 0, 'New_Selection')You can read more about SelectLayerByLocation in the online help. But it sounds like you really don't want to select features as much as grab some attributes. If that is the case, then I'd set up a search cursor, curse through the records, and if the shape of a feature intersects the poly we made above, grab the attributes of interest.
good luck,
Mike
