* A ControlEditor is a manager for a Control that appears above a composite and tracks with the moving and resizing of that composite. It can be used to display one control above another control. This could be used when editing a control that does not have editing capabilities by using a text editor or for launching a dialog by placing a button above a control. * <p> Here is an example of using a ControlEditor: * <code><pre> Canvas canvas = new Canvas(shell, SWT.BORDER); canvas.setBounds(10, 10, 300, 300); Color color = new Color(null, 255, 0, 0); canvas.setBackground(color); ControlEditor editor = new ControlEditor (canvas); // The editor will be a button in the bottom right corner of the canvas. // When selected, it will launch a Color dialog that will change the background // of the canvas. Button button = new Button(canvas, SWT.PUSH); button.setText("Select Color..."); button.addSelectionListener (new SelectionAdapter() { public void widgetSelected(SelectionEvent e) { ColorDialog dialog = new ColorDialog(shell); dialog.open(); RGB rgb = dialog.getRGB(); if (rgb !is null) { if (color !is null) color.dispose(); color = new Color(null, rgb); canvas.setBackground(color); } * } }); * editor.horizontalAlignment = SWT.RIGHT; editor.verticalAlignment = SWT.BOTTOM; editor.grabHorizontal = false; editor.grabVertical = false; Point size = button.computeSize(SWT.DEFAULT, SWT.DEFAULT); editor.minimumWidth = size.x; editor.minimumHeight = size.y; editor.setEditor (button); </pre></code> * @see <a href="http://www.eclipse.org/swt/">Sample code and further information</a>
