Activated/Deactivate Toolbar icons

[Metal Wing]

Hello,

This has been asked many times; however, the results that seemed to have answers either had broken links or I simply couldn't comprehend them.

My case is relatively simple. I have a Toolbar1 and on it Action1, Action2 and Action3 that I have created as "Always Enabled".

My goal is to click Action1 and that will Disable Action2 and Action3.

Q1: Could it be done without creating action as Conditional?

Q2: How?

Q3: If Conditional action is required, what should I pick (Project, Cookie, DataObject?)

Thank You,

Denis

Yes, I've seen that. I've actually went through the first 7 pages of google and tried every solution I could, that I've found.

The link you gave, is the one I had the most hopes in, but I still don't quite grasp the concept of the following:

I make an Always Enabled Action1.
I need to make a Conditionally Enabled Action2 which will only light up if Action1 was pressed AND become disabled again if Action3 was pressed.

Unfortunately, I can't seem to get my head around how I would do that...

Any further hints are greatly appreciated!

I think the following will work for your case.

You have an "always enabled" action --> Action1.

You have then a Conditionally enabled Action2. To do this, define your Action2 as a conditionally enabled one, with String as the context (that combobox that shows up under conditionally enabled actions is an editable combo box). This is a fake (String) object. I am assuming that you are not putting strings into your lookup through other modules. If you have strings put into the lookup through other modules (or class files), use a stupid fake object.

Action1, when clicked, should try to process a class (extending ActionListener). In the actionPerformed method of Action1 class, process whatever you need to, and then put a fake string (or a fake object) into the lookup. This should light up Action2.

In the actionPerformed method of Action3, process whatever you need to and then, search for all string objects (or fake objects if you have used a fake object to light up Action2) in the lookup and then remove all of them from lookup (there is probably only one fake string/object). This will disable Action2.

I have had similar requirements recently. For adding and removing objects to and from lookup, I used CentralLookup by Wade Chandler. Adding and removing items using CentralLookup is simpler, especially from classes extending ActionListener.

Trust the above helps.
