When I press on a text field in PolyScope, no keyboard is displayed. For example, I want to enter a title as shown in the image below. Does anyone know how this can be done?

If you are using the starter package, it contains some example URCaps that use keyboards. I would recommend reading through their implementation to get a better idea of how to make keyboard API calls.   
  
I hope this all helps!

**The following links could be of some benefit for reference in developing swing objects:**

- [Universal Robots - URCap - Choosing Swing or HTML (universal-robots.com)](https://www.universal-robots.com/articles/ur/urplus-resources/urcap-choosing-swing-or-html/)
- [KeyboardInputFactory (api 1.13.0 API) (universal-robots.com)](https://plus.universal-robots.com/apidoc/115998/com/ur/urcap/api/domain/userinteraction/keyboard/keyboardinputfactory.html)
- [Universal Robots - URCap - API Reference Docs (universal-robots.com)](https://www.universal-robots.com/articles/ur/urplus-resources/urcap-api-reference-docs/)

Here is an example from the first link I provided:

**VIEW CLASS**

```auto

	private Box createInputBox(final JTextField textField,
			final ContributionProvider<samplesProgramNodeContribution> provider) {
		Box box = Box.createHorizontalBox();
		box.setAlignmentX(Component.LEFT_ALIGNMENT);

		textField.setFocusable(false);
		textField.addMouseListener(new MouseAdapter() {
			@Override
			public void mousePressed(MouseEvent e) {
				KeyboardTextInput keyboardInput = provider.get().getKeyboardForInput();
				keyboardInput.show(textField, provider.get().getKeyBoardCallBack());
			}
		});

		box.add(textField);

		return box;
	}

	public void setINPUTtextField(String text) {
		this.inputTextField.setText(text);
	}

```

**CONTRIBUTION CLASS**

```auto

	private static final String INPUT_KEY = "input_key";
	private static final String INPUT_DEFAULT_VALUE = "not set";

	public KeyboardTextInput getKeyboardForInput() {

		KeyboardTextInput keyboard = keyboardInputFactory.createStringKeyboardInput();

		return keyboard;

	}

	public KeyboardInputCallback<String> getKeyBoardCallBack() {
		return new KeyboardInputCallback<String>() {

			@Override
			public void onOk(String value) {

				final String inputText = value;

				undoRedoManager.recordChanges(new UndoableChanges() {

					@Override
					public void executeChanges() {

						model.set(INPUT_KEY, inputText);

					}
				});

				view.setINPUTtextField("Your input is: " + model.get(INPUT_KEY, INPUT_DEFAULT_VALUE));

			}

		};
	}

```
