Re: [sapphire-dev] diagram floating palette question

[Greg Amerson <gregory.amerson@xxxxxxxxxxx>]

I spent a few minutes playing around with the popupmenu support for floating palette.  Also I added the Sapphire.Add to this floating palette for you guys to evaluate.  Attached is a patch for getting submenus to work.  See screenshot of them in action:

Thanks for taking a look at this,

Also, I noticed in the code that the Sapphire.Add context is not added to the floating palette.  What do you guys think about adding that?  Currently in my diagram editor I have a Sapphire.Add context on the node and would like to see if it would be possible to have it show up as well.

Also, as you can see on my screenshot, some of my action factories don't actually render any actions when nodes have particular state (see the first action on top left in my screenshot).   So I think we should protect the adding of actions to the floating palette to check to see if they are actually enabled.

Looking at the floating palette code it seems that it supports the notion of popup menus.  Can we take advantage of this for when actions have multiple handlers (as in the case of action handler factories)?

Hey guys,

I just synced and see the new floating palette (very nice!).  However, I see some issues with the floating palette and the action handler factories that I have added to a particular node.  See this screenshot:

  

You can see that I have 3 action handler factories, one for Sapphire.Add, and two for Sapphire.Edit (that I have added in my sapphire-extension.xml).  Sometimes these nodes action handler factories have sub menus, but I don't see these on the floating palette. It just seems to execute the first action from the sub menu.

Any thoughts?
