@Deprecated public class TableTreeEditor extends ControlEditor
Deprecated.As of 3.1 use TreeEditor with Tree, TreeItem and TreeColumnA TableTreeEditor is a manager for a Control that appears above a cell in a TableTree and tracks with the moving and resizing of that cell. It can be used to display a text widget above a cell in a TableTree so that the user can edit the contents of that cell. It can also be used to display a button that can launch a dialog for modifying the contents of the associated cell.Here is an example of using a TableTreeEditor:
final TableTree tableTree = new TableTree(shell, SWT.FULL_SELECTION | SWT.HIDE_SELECTION); final Table table = tableTree.getTable(); TableColumn column1 = new TableColumn(table, SWT.NONE); TableColumn column2 = new TableColumn(table, SWT.NONE); for (int i = 0; i < 10; i++) { TableTreeItem item = new TableTreeItem(tableTree, SWT.NONE); item.setText(0, "item " + i); item.setText(1, "edit this value"); for (int j = 0; j < 3; j++) { TableTreeItem subitem = new TableTreeItem(item, SWT.NONE); subitem.setText(0, "subitem " + i + " " + j); subitem.setText(1, "edit this value"); } } column1.setWidth(100); column2.pack(); final TableTreeEditor editor = new TableTreeEditor(tableTree); //The editor must have the same size as the cell and must //not be any smaller than 50 pixels. editor.horizontalAlignment = SWT.LEFT; editor.grabHorizontal = true; editor.minimumWidth = 50; // editing the second column final int EDITABLECOLUMN = 1; tableTree.addSelectionListener(new SelectionAdapter() { public void widgetSelected(SelectionEvent e) { // Clean up any previous editor control Control oldEditor = editor.getEditor(); if (oldEditor != null) oldEditor.dispose(); // Identify the selected row TableTreeItem item = (TableTreeItem)e.item; if (item == null) return; // The control that will be the editor must be a child of the Table Text newEditor = new Text(table, SWT.NONE); newEditor.setText(item.getText(EDITABLECOLUMN)); newEditor.addModifyListener(new ModifyListener() { public void modifyText(ModifyEvent e) { Text text = (Text)editor.getEditor(); editor.getItem().setText(EDITABLECOLUMN, text.getText()); } }); newEditor.selectAll(); newEditor.setFocus(); editor.setEditor(newEditor, item, EDITABLECOLUMN); } });
