List<TreeTableColumn> columns = new ArrayList<TreeTableColumn>();
TreeTableColumn column = new TreeTableColumn("name", "Name", 300);
column.setMinWidth(75);
columns.add(column);

column = new TreeTableColumn("date", "Date", 170);
columns.add(column);

column = new TreeTableColumn("size", "Size", 120);
columns.add(column);

TreeTableColumnModel cm = new TreeTableColumnModel(columns);

final TreeTable table = new TreeTable(cm);
table.setAnimate(false);
table.setItemIconStyle("icon-page");

ContentPanel panel = new ContentPanel();

rojar,

this works for me... but is not using data models.



private TreeTable getTreeTable() {

List<TreeTableColumn> columns = new ArrayList<TreeTableColumn>();

TreeTableColumn col = new TreeTableColumn("Name", 0.40f);
col.setMinWidth(75);
columns.add(col);

col = new TreeTableColumn("Author", 0.30f);
columns.add(col);

col = new TreeTableColumn("Genre", 0.30f);
col.setAlignment(HorizontalAlignment.RIGHT);
columns.add(col);

TreeTableColumnModel cm = new TreeTableColumnModel(columns);

TreeTable tbl = new TreeTable(cm);

TreeItem ti = tbl.getRootItem();
for (int n = 0; n < 6; n++) {
TreeItem item = new TreeItem("test");
ti.add(item);
item.add(new TreeTableItem("item" + n, new Object[] { "item" + n, new Double(n + 4.3),new Double(n + 144.3) }));
}
tbl.setBorders(false);
return tbl;
}
