Get Toolbars from ObjectSpace

Jim

I can get a collection of UI::Toolbar objects using the following code:

toolbars = [] ObjectSpace.each_object(UI::Toolbar) {|t| toolbars.push(t)}

But, in some plugins, the Toolbar is created in a module namespace:

module JF tb = UI::Toolbar.new("Hello Toolbar") end

And these do not show up when using the ObjectSpace code. Is there a way to find them also?

Hmm, that's not what I'm seeing. The tool I'm working on, I create the toolbar from within my module. But it comes up just fine with your code, slightly modified to show names

ObjectSpace.each_object(UI::Toolbar) {|t| puts t.name}

I guess it probably won't show them if they are created after SU loads though, since they are not created in SU.

Jim

You are right - my bad, I see the Toolbar also. Just an oversight on my part.

However, when I do the show/hide on a Ruby Toolbar, it looks like a new Toolbar object is created each time, so multiple Toolbars of the same name (but different id's) are being created using UI.toolbar("name") to access the Toolbar.

UI.toolbar("Test").object_id returns a new value each time it is called.

5.times {p UI.toolbar("Jim").object_id}

This is a Windows thing. For instance each time the Console window is shown (then hidden,) then shown again, a new Window instance is created. (It's handle changes.) Since toolbars are also window objects, they'll have the same behavour.

Thanks Dan.

I was seeing a lot of what looked like unnecessary Toolbars objects being created in ObjectSpace after using UI.toolbar("name"), but I see they go away after a GC.start - so I guess this is a non-issue.

Jim

Ok, I see it now.

If I create a Toolbar like so:

cmd = UI::Command.new("Command") { do_something } UI.toolbar("Do Something").add_item(cmd)
or
UI::Toolbar.new("Do Something").add_item(cmd)

The Toolbar does not show up in ObjectSpace (although does exist in SketchUp,) presumably because there is no reference to it?

If I do it this way:

cmd = UI::Command.new("Command") { do_something } tb = UI.toolbar("Do Something") tb.add_item(cmd)

The Toolbar does show in ObjectSpace, even when tb is a local var that goes out of scope.

Yea that's weird. I never recommend using any constructor without making sure that there is a reference to it for later use.

We are still lacking (auto-generated) collections for many types of things, incl. toolbars.

Either the collection object would be "held" by the UI module (ie: UI::ToolbarSet,) or "held" by the class itself, and accessed via a class method.
