Attach Actions to SourceListItems

[GoogleCodeExporter]

What would be really, really nice, would be if I could add an instance of
javax.swing.Action to a SourceListItem. Or something similar.

What is it you want to do in the ActionListener? 

Maybe it would make more sense to introduce a SourceListViewController if your 
trying to toggle views based on 
what item is selected.

This would keep the SourceList class free of particular usage patterns.

Enabling SourceItems (potentially SourceListCategories too) to be configured 
via an
Action will increase code reuse. A SourceListClickListener may delegate to an 
item's
action to handle the click event for instance.

Thanks for the feedback Andres. Can you show me what you want your Groovy 
syntax to look like? That'll give 
me a better idea of your use case.

Sure, this is what I have in mind

class DefaultSourceListClickListener implements SourceListClickListener {
  void sourceListItemClicked(SourceListItem item, Button button, int clickCount) {
    Action action = item.getAction()
    if( action && item.enabled ) {
      ActionEvent evt = ...
      action.actionPerformed(evt)
    }
  }

  void sourceListCategoryClicked(SourceListCategory category, Button button, int
clickCount) {
    ... // similar impl as above
  }
}

actions {
  action(id: "checkEmailAction",
    smallIcon: imageIcon("/icons/email.png"),
    closure: controller.checkEmail)
}

sourceList(id: "sl") {
  sourceListCategory("Mail") {
    sourceListItem(checkEmailAction, text: "John Doe")
    sourceListItem(checkEmailAction, text: "Jane Doe")
  }
}
sl.addSourceListClickListener(new DefaultSourceClicklistener())

Both items will inherit the same icon and actionListener, 
DefaultSourceClicklistener
makes sure to delegate to the appropriate action if it exists and if it is 
enabled. I
believe items/categories are always enabled, does it make sense to disable them?
(don't know if Apple HIGs define this behavior).

Thanks Andres. Would it be better if I just called the action for you when an 
item was selected?

That would take care of the click event if a DefaultSourceClickListener is 
registered
upon SourceList creation. My concern is also about the looks of an 
Item/Category, as
if you update an action's properties so must the configured Item/Category.

I'm not sure if Item/Category support updating their text/icon after they are
created. In any case we can prototype this on MacwidgetsBuilder without 
affecting
Macwidgets directly, thanks to Groovy's metaprogramming facilities :-)

Issue 5 has been merged into this issue.

Is this issue ever going to be resolved? What is the use of the sourcelist if 
you cant apply actionevents to it?

You can react to selection events using a SourceListSelectionListener:

Thanks for the quick response! I tried adding it with minimal success. Can you 
look at this snippet and tell me what Im doing wrong?

// Source List
            SourceListModel model = new SourceListModel();

            // Source List Category
            SourceListCategory category = new SourceListCategory("Views");
            model.addCategory(category);

                    // Create Source List Items
                    SourceListItem codeViewItem = new SourceListItem("Code View", new ImageIcon(FrameController.class.getResource("assets/TreeIcons/codeView.png")));
                    SourceListItem debuggerItem = new SourceListItem("Debugger", new ImageIcon(FrameController.class.getResource("assets/TreeIcons/debuggerView.png")));
                    SourceListItem profilerItem = new SourceListItem("Profiler", new ImageIcon(FrameController.class.getResource("assets/TreeIcons/profilerView.png")));

                    // Add Source List Items
                    model.addItemToCategory(codeViewItem, category);
                    model.addItemToCategory(debuggerItem, category);
                    model.addItemToCategory(profilerItem, category);

            // Add Source List Categorys
            SourceList sourceList = new SourceList(model);

            // Set Selected Source List Item
            sourceList.setSelectedItem(codeViewItem);

            // Create Source List Listener
            new SourceListSelectionListener() {
                    public void sourceListItemSelected(SourceListItem sli) {
                        System.err.println(sli);
                    }
            };

You need to install the SourceListSelectionListener you created on your 
SourceList:

http://exploding-
pixels.com/google_code/javadoc_0.9.5/com/explodingpixels/macwidgets/SourceList.h
tml#addSourceListSelecti
onListener(com.explodingpixels.macwidgets.SourceListSelectionListener)
