Darling Harbour Eats

FOSS4G is happening next week! It seems like a long way away - and it is the other side of the world for a lot of people. Given that it is the other side of the street from LISAsoft offices I am going to try and give some pointers on where to eat.

I will start with where people will actually be:

Now this location is nothing fancy - but here is the deal. It is open 24 hours; and a lot of attendees will be jet lagged - and this place will be open.

And you know ... pancakes.

Taking Boiler Plate out of Examples

I was reviewing the GeoTools example code today with Michael Bedward - preparing for an a tutorial at FOSS4G this year.

One of the things that always comes up in example code; is the requirement to "show" the result. As a result a the majority of our example code was actually examples of how create quick and dirty swing user interfaces.

So our day was spent stripping out boilerplate user interface code to a jar appropriately tilted "gt-swing" so that examples can stay focused on being examples.

Here is a small example of a wizard page for connecting to a shape file:


Here is before:

File file;

JFileChooser chooser = new JFileChooser();

chooser.setDialogTitle("Open Shapefile for Reprojection");

chooser.setFileFilter(new FileFilter() {

public boolean accept(File f) {

return f.isDirectory() || f.getPath().endsWith("shp")

|| f.getPath().endsWith("SHP");

}

public String getDescription() {

return "Shapefiles";

}

});

int returnVal = chooser.showOpenDialog(null);

if (returnVal != JFileChooser.APPROVE_OPTION) {

System.exit(0);

}

file = chooser.getSelectedFile();

And here is after:

File file = JFileDataStoreChooser.showOpenFile("shp", parent );

The other thing that has happened in cleaning up examples is a real focus on the style interfaces. Specifically going through and making sure all the new concepts introduced are accessible, and ensuring that deprecated methods are not used in example code.
