20040707: IDV - linux - adding new classes to the IDV
- Subject: 20040707: IDV - linux - adding new classes to the IDV
- Date: Thu, 08 Jul 2004 09:38:31 -0600
Inquiry: I want to add new files (classes) to the
package ucar.unidata.ui.symbol. The new java file is present
but when I do ant idvjars it is not complied and included. If I try javac on the file I get error messages like "package ucar.unidata.ui.drawing does not exist." How do I check in the new classes to the idv?
Hi Stu,
First of all I would suggest that, for your Unavco work, that you have a
separate package structure, e.g.,
edu.unavco.idv. ...
and place your new code there. We are not set up right now to include
code developed elsewhere. Plus,
I am guessing that this new symbol is Unavco specific?
The likely reason your new class is not getting compiled is that it does
not get referenced anywhere.
If you look at the ucar/build.xml file under the idv target you will see
that we only compile code
under the unidata/idv, unidata/data and unidata/apps package. The reason
the symbol classes get compiled
in the ui/symbol package is that they are each explicitly referenced by
the ucar.visad.display.StationModelDisplayable class.
If you are going to put your new code under the ucar package (which I
would strongly discourage) you could
add a line the the idv target in build.xml that will include the
ui/symbol directory.
p.s. - The latest version of the IDV (which will be released in the
beginning of August) has a facility to
define your own symbols and incorporate them into the Station Model
Editor. You still need to create a new
class but this gives you a way to seamlessly add in that class to the
editor and have it used by the StationModelDisplayable.
