Detect if cpoint is clicked

maricanis

Hi,

I'm reading API and it seems that InputPoint class can't detect if cpoint is clicked? It there some other method to detect it?

Description of my problem
I'm calculating some values for numerous sensors in the model. When importing data back into model, plugin create cpoint for each sensor, and idea is when user click on cpoint to show its value (in tooltip, if possible, or in some other report dialog, if not possible).

My current implementation creates cpoints and also add text into model (containing value for the point). Problem is that such text entities (one for each sensors, and there can be 10000 sensors or so), make model overcrowded and difficult to explore.

New idea is to add only cpoints into model, and then show values to user 'on demand' - click or mouse move.

Back to the problem, I can detect current mouse position, but how to check if it is on cpoint or not?

Any ideas? Is there some plugin that does similar import of numerical values, since I'm searching for some solution comfortable for user and efficient!

Thanks in advance,
Marija

Have you tried the PickHelper class?

Hi,

I've managed to make it work, with help of Thom Thom's Pick It tool and PickHelper and this thread http://sketchucation.com/forums/viewtopic.php?f=180%26amp;t=48919%26amp;p=439766%26amp;hilit=tooltip#p439766

Idea is to detect leaf with PickHelper, and if it is cpoint then print whatever needed

def onMouseMove(flags, x, y, view)
      ph = view.pick_helper
      ph.do_pick(x, y)
      ph.count.times { |index|
        ent = ph.leaf_at(index)
        if ent.class == Sketchup;;ConstructionPoint
            view.tooltip = ent.to_s
            break
        end
      }
      view.refresh
end

Thanks Thom,

Why do you need to call view.pick_helper each time the mouse moves ?

Can't you use @ph = view.pick_helper in the tool's activate callback ?
And then re-use the pick_helper instance reference ?

Hi Dan,

Good point for defining pick helper only once, and then use it. I was concerned what would happen if user select other Scene for example while tool is active, but it seems it is working fine.


def activate
    view = Sketchup.active_model.active_view
    @ph = view.pick_helper
end

def onMouseMove(flags, x, y, view)
    @ph.do_pick(x, y)
    @ph.count.times { |index|
    ent = @ph.leaf_at(index)
    if ent.class == Sketchup;;ConstructionPoint
         view.tooltip = ent.to_s
         break
     end
    }
    view.refresh
end

Thanks again,
Marija

I believe the active_view is a singleton object of the model. (there is only one.) The user sees scene pages through the active_view.
