TableWidget
Table Widget
The TableWidget can be used to handle data grids. Data sources should implement
the TableModel interface. Several useful implementations are provided out of the
box.
Cell contents are converted to their respective text representations using their
toString() method. Numbers are automatically aligned horizontally in a smart
way.
List to table
The TableModelCollectionAdapter can be used to wrap a collection of items
in a single column table.
+--------+ | Fruit | +--------+ | Orange | | Apple | | Lemon | +--------+
Source code:
:::java
List<String> items = new ArrayList<String>();
items.add("Orange");
items.add("Apple");
items.add("Lemon");
TableModel tableModel = new TableModelCollectionAdapter(items, "Fruit");
TableWidget tableWidget = new TableWidget(tableModel);
CharacterRaster raster = new ExtensibleCharacterRaster(' ');
tableWidget.render(new RasterContext(raster));
System.out.println(raster);
Map to table
The TableModelCollectionAdapter can be used to wrap a collection of items
in a single column table.
+-----------+-----------+ | City | Value | +-----------+-----------+ | Amsterdam | 3.1415 | | London | 2012.0 | | Paris | 42.0 | +-----------+-----------+
Source code:
:::java
Map<String, Double> items = new TreeMap<String, Double>();
items.put("Paris", 42.);
items.put("London", 2012.);
items.put("Amsterdam", 3.1415);
TableModel tableModel = new TableModelMapAdapter(items, "City", "Value");
TableWidget tableWidget = new TableWidget(tableModel);
CharacterRaster raster = new ExtensibleCharacterRaster(' ');
tableWidget.render(new RasterContext(raster));
System.out.println(raster);
Custom table
A custom TableModel implementation may directly
extend AbstractTableModel.
+----------+----------+----------+----------+ | Column 0 | Column 1 | Column 2 | Column 3 | +----------+----------+----------+----------+ | 00:00 | 01:00 | 02:00 | 03:00 | | 00:01 | 01:01 | 02:01 | 03:01 | | 00:02 | 01:02 | 02:02 | 03:02 | | 00:03 | 01:03 | 02:03 | 03:03 | | 00:04 | 01:04 | 02:04 | 03:04 | | 00:05 | 01:05 | 02:05 | 03:05 | +----------+----------+----------+----------+
Source code:
:::java TableWidget tableWidget = new TableWidget(new CustomTableModelImpl()); CharacterRaster raster = new ExtensibleCharacterRaster(' '); tableWidget.render(new RasterContext(raster)); System.out.println(raster); class CustomTableModelImpl extends AbstractTableModel { @Override public int getWidth() { return 4; } @Override public int getHeight() { return 6; } @Override public String getCellContent(int x, int y) { return String.format("%02d:%02d", x, y); } @Override public String getColumnTitle(int x) { return "Column " + x; } }
