Open Elements – JGrid Tutorial #1

Warning This article is outdated and may contain incorrect information.

At the moment all JGrid demonstrations are very complex and use a lot of Java2D code, web services an so on. So many people asked me to create some simple demos. For this reason I started some bottom-up tutorials for the JGrid.

Here is the first one: You can integrate a JGrid in every swing application. Just add it to a container:

JGrid grid = new JGrid();
getContentPane().add(new JScrollPane(grid));

Normally you want to visualize some data in the grid. All data must wrapped in a ListModel:

DefaultListModel model = new DefaultListModel();
for(int i=0; i &lt; 100; i++) {
  model.addElement(new Integer(i));
}

In a final step you must set the model for the grid:

grid.setModel(model);

With this few lines of code you can add a JGrid to your code. Because the default renderer of the grid uses a label and renders the toString()-result of the data to the grid you will see all Integers in a grid:

You can download the source file for the tutorial. To run the program you need the jgrid.jar in your classpath.
