The default behavior of the system is to - * provide no traversal for canvas controls. This means that by - * default in a canvas, a key listener will see every key that the - * user types, including traversal keys. To understand why this - * is so, it is important to understand that only the widget implementor - * can decide which traversal is appropriate for the widget. Returning - * to the <code>TRAVERSE_TAB_NEXT</code> example, a text widget implemented - * by a canvas would typically want to use the tab key to insert a - * tab character into the widget. A list widget implementation, on the - * other hand, would like the system default traversal behavior. Using - * only the doit flag, both implementations are possible. The text widget - * implementor sets doit to <code>false</code>, ensuring that the system - * will not traverse and that the tab key will be delivered to key listeners. - * The list widget implementor sets doit to <code>true</code>, indicating - * that the system should perform tab traversal and that the key should not - * be delivered to the list widget. - * </p><p> - * How can the traversal event be used to override system traversal? - * When the return key is pressed in a single line text control, the - * detail field is <code>TRAVERSE_RETURN</code> and the doit field - * is <code>true</code>. This means that the return key will be processed - * by the default button, not the text widget. If the text widget has - * a default selection listener, it will not run because the return key - * will be processed by the default button. Imagine that the text control - * is being used as an in-place editor and return is used to dispose the - * widget. Setting doit to <code>false</code> will stop the system from - * activating the default button but the key will be delivered to the text - * control, running the key and selection listeners for the text.
