I can't seem to find anyway to display a dialog from within one of the
MoveDeleteHook methods.
I've tried Display.getCurrent() and that's null.
AbstractUIPlugin.getWorkbench().getActiveWorkbench() is null, and if I do
getActiveWorkbenchs[0].getShell() I get a Shell, but the dialog throws an
exception when I'm creating it.
I guess the delete at that point is running on a seperate, non-ui thread?
Shouldn't I still be able to somehow display a dialog? Can I get access to
that thread somehow since it's not being passed into the overrides?
Any help would be greatly appreciated.
Thanks,
harpstein

It is odd that Display.getCurrent() is returning null. This and your
other problem possibly indicate that you are not properly set up for
self hosting (i.e. when you run the Eclipse containing you plugin, it
seems that othe plugins are missing). You may want to check the PDE doc
on setting up a workspace for self-hosting.
Here is one way to get a Shell to display a dialog (assuming your plugin
references the org.eclipse.ui.workbench plugin):
Display.getDefault().syncExec(
new Runnable() {
public void run() {
Shell shell;
IWorkbenchWindow window =
PlatformUI.getWorkbench().getActiveWorkbenchWindow();
if (window == null) {
Display display = Display.getDefault();
shell = new Shell(display);
} else {
shell = window.getShell();
}
// Use shell to open dialog
}
});
