In my RCP application, there is a CTabFolder in the view, containing
three CTabItems: bookstore,category and books, and each CTabItem has a
Composite as its control, also, each Composite contains a TableViewer to
show some informations.
There is some menuitems in the menu such as: "add bookstore","delete
bookstore","add category","delete category",etc.
And, what I want to implement is: if I click the content of
bookstoreTable, the "delete bookstore" action should be enabled, and If
I click the content of categoryTable, the "delete catagory" action
should be enabled and "delete bookstore" action should be disabled, etc.
If there's only one CTabItem, I can easily deal with it by
add a line:
getSite().setSelectionProvider(tableviewer)
to the view class and implement a ISelectionListener together with the
selectionChanged() method.
But there're three tableviewers, I don't know what to do now.
Thank you very much.

Hi,
define your own ISelectionChangedListener with the scope of one TableViewer
something like:
myBookStoreTable.addSelectionChangedListener(new
ISelectionChangedListener() {
public void selectionChanged(event) {
if (!event.getSelection().isEmpty() {
deleteBookstoreAction.setEnabled(true);
myOtherAction.setEnabled(false);
//disable other actions...
} else {
//handle deselect
}
}
});

Cheerz,
Tom

Sorry, I have another problem, as the actions are initialized in
ApplicationActionBarAdvisor.
If I define ISelectionChangedListener with the scope of one TableView,
maybe this solution tightly coupled the actions with TableViews, because
I have to expose the references to the actions to the TableViews.
Isn't it?
Thanks.
Best Regards
Chandler
