How to enable select all? [message #155225]

Logic example allows to select all. Again, I am lost in the 121 classes
to find the line(s) of code that enable Edit/Select All functionality.
Where is the magic that does it hidden? Thanks in advance!

It's not in any of those 121.
I would start with the class called SelectAllAction. Go to its constructor
and press CTRL+ALT+H.

Once again, an excellent tip. Thanks Randy. Just for those who have a
similar question in the future, here is how it is done. The LogicEditor
class overrides the protected method createActions. In it, however, the
parent's class version is called first:

protected void createActions() {
super.createActions();
...

If you take a look at the GraphicalEditor class you will see the code
where the action is created:

protected void createActions() {
ActionRegistry registry = getActionRegistry();
IAction action;
...
action = new SelectAllAction(this);
registry.registerAction(action);

In LogicActionBarContributor, which is a class registered as the
contributor to the editor class in plugin.xml, the select all action is
registered as a global action:

protected void declareGlobalActionKeys() {
addGlobalActionKey(IWorkbenchActionConstants.PRINT);
addGlobalActionKey(IWorkbenchActionConstants.SELECT_ALL);
addGlobalActionKey(IWorkbenchActionConstants.PASTE);
}

Note that the above uses deprecated constants and a better way would be
to do

addGlobalActionKey(ActionFactory.SELECT_ALL.getId())

for the select actions. Similar change can be performed for the paste
and print actions, though I have not tested it, yet.

You may have overridden createActions() and not called super. I have
changed the JavaDoc to explicitly state that subclasses should *extend* this
method, which means that you need to call super.createAction(). Most places
we are using "override" and "extend" correctly, but not here apparently.
