eclipse4book's Issues

Add exercise for ExitHandler on exiting window

An exercise to override the default handling of closing a window should be added.

How to control dynamically enabled/disabled state of direct tool item which was added into toolbar？

Use constants for the @Preference example

At the moment we use literals. @SimonScholz please send PR for an update.

Note: in "Effective Java" is is recommended not to use Interfaces for constant definitions. We should use a final private class for that.

This can be solved by installing an older version of the libwebkitgtk like this:

sudo apt-get install libwebkitgtk-1.0-0

Found this solution here: https://groups.google.com/forum/#!topic/xmind/5SjPTy0MmEo

I am not sure, if this is the best solution, but in case a customer has this issue we got a solution here. :)

Switch translation to use camelCase

See #11 (comment)

Use databinding in Password dialog

We should add an optional exercise to migrate the Password dialog to databinding. This requires for the lifecycle manager to use an explicit realm.

See:
https://wiki.eclipse.org/JFace_Data_Binding/FAQ#What_is_a_Realm.2C_and_do_I_need_to_care.3F
https://wiki.eclipse.org/JFace_Data_Binding/Realm

Chapter "83.4 Implement data binding" contains duplicate Binding

The last 3 lines of code can be removed as they already exist above.

IObservableValue target = WidgetProperties.text(SWT.Modify)
.observe(txtSummary);
IObservableValue model = BeanProperties.value(Todo.FIELD_SUMMARY).observe(todo);
ctx.bindValue(target, model);

See Page 283 in the current Script

NullpointerExeption in TodoDetailsPart.updateUserInterface()

Hi,
TodoWizardPage1.createControl(..) is

		part.createControls(container, messagesRegistry);
		part.setTodos(Collections.singletonList(todo));

should be:

		part.setTodos(Collections.singletonList(todo));
		part.createControls(container, messagesRegistry);
