Here is the "solution" I found for my problem, maybe it can help.
I am not sure if it is the official way, but this was the only thing
that worked for me.
1) Create a Viewer extending
org.eclipse.jdt.internal.ui.packageview.PackageExplorerPart
2) Create your own RenameAction class extending
org.eclipse.jdt.ui.actions.RenameAction;
3) Overwrite the run(IStructuredSelection) method in your RenameAction
with your checks and where your checks are not required call
super.run(IStructuredSelection).
This might require more tweaking since you have to write your own
dialog to enter the new name. The super.run() will still open the
old dialogs depending on the view.
4) in the init(IViewSite) method of your Viewer:
public void init(IViewSite site) throws PartInitException {
super.init(site);
renameAction = new MyRenameAction(site);
}
5) in the menuAboutToShow method of your Viewer:
get rid of the "old" refactor menu and inject our Action
(REFACTOR_MENU_ID = org.eclipse.jdt.ui.refactoring.menu)
public void menuAboutToShow(IMenuManager menu) {
super.menuAboutToShow(menu);
// now remove the things we do not want
MenuManager refactorMenu = (MenuManager)
menu.find(REFACTOR_MENU_ID);
if (refactorMenu != null) {
ActionContributionItem moveElement = null;
IContributionItem[] items = refactorMenu.getItems();
for (int i = 0; i < items.length; i++) {
if (items[i] instanceof ActionContributionItem) {
ActionContributionItem item =
(ActionContributionItem) items[i];
if (IJavaEditorActionDefinitionIds.
MOVE_ELEMENT.equals(item.
getAction().
getActionDefinitionId())) {
moveElement = item;
}
}
}
refactorMenu.removeAll();
refactorMenu.add(renameAction);
if (moveElement != null) {
refactorMenu.add(moveElement.getAction());
}
}
}
6) in the createPartControl method of your Viewer:
public void createPartControl(Composite parent) {
super.createPartControl(parent);
// add rename ActionHandler to Toolbar
getViewSite().getActionBars().
setGlobalActionHandler(JdtActionConstants.RENAME,
renameAction);
getViewSite().getActionBars().
setGlobalActionHandler("rename", renameAction);
}
I hope this helps in your case and doesn't cause serious heart attacks
among the eclipse developers ;-)
It would be nice to be able to add a validator to the Refactor/Rename
dialogs, maybe by using an extension point. I played around with
Refactor participants and such, but they get into the action when it is
too late already and I cannot give any feedback to the user.
Kind regards, Klaus
