How to avoid duplicates when adding custom menu items?

[Stein Rørvik]

A couple of years ago Wayne posted this example on how to add new menu entries, restoring the missing Bridge example image:

  item = "File>Open Samples>Bridge";
  class = "ij.plugin.URLOpener(\"bridge.gif\")";
  call("ij.Menus.add", item, class);

I would like to do the same, adding a custom menu entry whenever a certain macro toolset is loaded.

The problem is that every time the macro is loaded, a new duplicate menu entry is created.

Does anyone know how to avoid this?
I usually reload toolsets several times during a session.

Perhaps there should have been a

  call("ij.Menus.delete", item);

method as well?

Or a

  call("ij.Menus.update", item, class);

which would replace an existing menu entry with the given class when the method is called.

I can not use "Refresh Menus" as that clears both the window menu and reverts to the toolset loaded from StartupMacros, which is not what I want.

Greetings,

A partial answer to your query...

ij.Menus.add places the submenu moniker, i.e., "Bridge" in your example
into a hash.  There is a:
public static boolean commandInUse(String command)
method that should be callable using the macro call method that checks
this hash if this submenu moniker is already there. I do not know how a
boolean is translated into a string and it would not seem to be able to
discern submenu monikers in different parent menus.

Has any one else noticed that the ImageJ Java documentation has disappeared?

Hi,
you could List.setCommands and see if the command already exists:

List.setCommands;
cmd=List.get("Bridge");
print((cmd!=""),cmd);
cmd=List.get("Blobs");
print((cmd!=""),cmd);

Thanks Jerome,
this approach works fine!

My example can thus be rewritten as

item = "File>Open Samples>Bridge";
class = "ij.plugin.URLOpener(\"bridge.gif\")";
List.setCommands;
if(List.get("Bridge") == "") call("ij.Menus.add", item, class);

and I will get no duplicate entry.
