Dialog.addChoice with Variables / Variables in an Array?

[rayh]

Hi!
I'm setting up a macro in which the user is supposed to choose the applied file via a popup menu, as in this exemplary snippet:

Green = "File1";
Red = "File2";
choices = newArray("Green", "Red");
Dialog.create("Test");
Dialog.addChoice("Slide 1", choices);
Dialog.show();
Result = Dialog.getChoice();
print(Result);

The filepaths are set as variables, and I'd like the user's choice in the dialog to translate into the string of the respective variable, i.e. choosing "Green" or "Red" in the dialog is supposed to print "File1" or "File2", respectively -but instead I only recieve "Green" or "Red". How can I make the macro utilize the strings from the appropriate variables?

Green is a variable, "Green" is a string, so change the above to:

choices = newArray(Green, Red);

Thanks for your reply, but I already tried that, and when I do so the choices in the dialog box are both shown as "NaN", and I also recieve "NaN" from the print function. Unfortunately I didn't find any information if arrays are generally able to list variables. By chance, does anyone know if there's a possibility to somehow 'render' a string to a respective variable inside a macro?

So strange. Your modified example works fine here.

Green = "File1";
Red = "File2";
choices = newArray(Green, Red);
Dialog.create("Test");
Dialog.addChoice("Slide 1", choices);
Dialog.show();
Result = Dialog.getChoice();
print(Result);

How about this?

--snip--
files = newArray("File1", "File2", "Shazam");
choices = newArray("Green", "Red", "Blue");
Dialog.create("Test");
Dialog.addChoice("Slide 1", choices);
Dialog.show();
result = Dialog.getChoice();
for (i=0; i<choices.length; i++) {
if (result == choices[i]) {
file = files[i];
break;
 }
}
print(file);
--snap--

Ok, seems to be a problem related to the ImageJ version. The NaN stuff occured on 1.43m, when I run it on 1.48v it workes -though unfortunately not exactly as I wanted: Now File1 / File2 gets displayed in both the dialog and the print log, but I'd like the dialog to show Green and Red, while the print should yield File1 / File2. Is that possible?

Thanks a lot, that actually worked fine for me!
