public class TableTreeEditor
- extends
ControlEditor
A 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);
}
});
