gvSIG 2.0 Developmnet Training excercises
===================================================
My code and notes from the gvSIG 2.0 development course by the gvSIG
Association.
Have a nice day!
[Jorge](http://jorgesanz.net)
## Day 1
### Lesson 1
- Reviewed docs, nothing to note is a general introduction to the gvSIG
architecture.
### Lesson 2
- I start reading the lesson 2
- Change encoding of the workspace to ISO-8851
- I install gvSIG 2.0 dev version (build 2048)
- I have to change to metacity in order to be able to see the
_Create Plugin_ interface
- I can progress normally with the rest of the lesson to set up Eclipse
and review the initial layout of components
#### Notes
- I had to add an _export_ to the last line of the
`.gvisg.platform.properties`
- I had to execute `metacity --replace` to remove compiz so I can see
the _Create Plugin_ GUI
- The links on the documents refer to _https_ links on gvSIG portal.
They should link to the http version
- Is needed the official gvSIG header for this course? Is a good point
for official developments but for a
general development is not needed.
- On the _External tools_ favorite section `mvn create_installer` is
recommended but afterwards it doesn't appear at the screenshot
### Lesson 3
- I read the (great) documentation
- I create the asked interfaces and modify the `VisitorManager`
- I remove the `VisitorService` and associated tests
- I create the github repo so I can track changes on the files easily.
In fact I should do this first, so the changes on this first coding
lesson are not tracked but anyways they are small and easy to locate.
### Lesson 4
- Read the documentation
- Implement the asked methods on the tests (both API and Implementation)
- Add the dependencies on the impl `pom.xml`
- Cant't run the tests, I don't know were the tests are, tomorrow I'll
ask Chema about them and try to finish the exercise in time for the
deadline.
- Do the lesson test: 9.4, not bad
## Day 2
### Lesson 4
- Download the data so I can run the lesson tests
- Run the tests, I get an error so I have to debug to find that I had
an error on the raster path
- Next error was the name of `Gdal Store`. It's weird having to use
strings to load a store, there should be a way to find correct stores
or at least to list those keys. The exception about not finding the
store should be a good candidate to show available stores.
- All green, yay!!
- Trying to run the tests from `maven test` external tools but failed
- Make a `mvn clean` and `mvn compile` from parent project `org.gvsig.visor`
- I still have errors refering to an old `.getVisorService()` method
-------------------------------------------------------------------------------
Test set: org.gvsig.visor.impl.DefaultVisorManagerTest

- I'll ask on the forum and upload a clean clone of the repo
## Day 3
### Lesson 4
- Start adding comments to API classes and revise
the asserts as requested by the teacher
### Lesson 5
- Read the lesson, quite a lot of stuff to do, that's great!!
- No real coding job done today
## Day 4
### Lesson 5
- Coded folowwing the lesson materials, almost without any problem
- The test specification was not understood on the first read but after
doing the rest of the coding the test was clearer and easier to do
- The test ask for `COORDX` and `COORDY` instead of `COORX` and `COORY`
- Added normal comments but no javadocs as almost all code was on the
implementation, not on the API side.
## Day 5
### Lesson 6
- Coded following the lesson materials without major problems, no
debug at all
- The HTML from `getText()` was not well formed but it worked
- The rest of the time was spent on improving the panel for the blocks with
- Formatting area and perimeter numbers
- Formatting the date properly
- Addindg old HTML tags for bold fonts
- Defining a default sensible size
- Setting an specific font for better bold texts looking
- Addind an empty border so the elements are not so close to the border
- I would use a gridbag layout but, meh, the border layout is cool
- As always, coding a reasonable good GUI takes more time than any other
component on a Java app
## Day 6
- Just fixing small things commented by the teacher to improve my code
- Add explicit `private` modifiers for class variables to improve encapsulation
- Remove `this` when accessing class properties when there is no chance for error
with local variables. This is more a convention. And I don't like it, I think is
a good practice because it makes more understandable the code.
## Day 7
### Lesson 7
- Reading the lesson materials
- When doing a `mvn install` on the `mainplugin` project the process doesn't finish
with a cryptic error. The mvn log is at [pastebin](http://pastebin.com/PWy8NkCa) and
I've reported it at the forum. Anyway it doesn't blocks the rest of the lesson.
- Did the changes requested on the materials, quite easy by the way and compiled and
installed on the gvSIG plugin folder
- Started gvSIG and assured the extension was there (no GUI yet).
## Day 8
## Lesson 8
- Reading the lesson materials carefully
- Coding the extension slowly but without any real problemw materials are great
- I've just changed the tool from an `action-tool` to a `selectable-tool` and
reported it to the course forum
- It seems I've found a small bug on the selectable toolbar buttons behaviour,
also reported at the forum
- Anything more, the exercises now are more interesting as we are working with
the gvSIG top level objects: mapcontrol, views, etc.
