Is there a screen text method?

[denis_bolomier]

Hi all,
I need to export the name of the scene when I export an image and I dont’ find add_screen_text function:
Is there a screen text api ? (text fixed on the screen)
I tried “ad_text” but the function need the point.
Best regards !

why not add it to the filename?

    title = Sketchup.active_model.title
    pages = Sketchup.active_model.pages
    if not pages.length == 0
          name = pages.selected_page.name.gsub(/[\s\[\]\{\}\(\)\/\\\<\>]/,"_")
          # deal with pages by appending name to title...
          title = title + '_' + name
    end

then use title in your image export code…

there is also

     model = Sketchup.active_model
 # Add a note 1/10 ways down the screen and 1/10 ways right from the
 # upper left corner of model window.
 note = Sketchup.active_model.add_note('Hello World', 0.1, 0.1)

so you could combine the to and add the name to the screen note…

Any technique you use to display text on the screen is going to need to know where to place it! view#draw_text is an alternative that ties the location to the viewport, not to the model.

@slbaumgartner

view#draw_text is an alternative

@slbaumgartner,
Steve, does text written to view show in ‘export’ of an image?

[slbaumgartner]

Maybe - but on rechecking, it isn’t of much use anyway because it is one of those poorly documented API methods that only works from within the draw method of a Tool.

[john_drivenupthewall]

that also crossed my mind, bit of a pain just to tag an image…

[slbaumgartner]

If @denis_bolomier needs a visible, on-image label, add_note may be the best existing alternative. The “note” it creates is actually a special Text Entity that is fixed at a screen location. It doesn’t need to be in a Tool draw method.

… and he needs to add each note to a scene specific layer, as I explained in “Adding text to a scene”, via the manual tool:

Adding text to a scene

Yes it’s a closely guarded secret! Add a layer that is specific to each scene that you wish to “label”. Ex: “Scene 1 Label”, “Scene 2 Label”, etc. (If you already have layers that each scene has, and no others do… then you can use those.) Make sure each scene is updated with it’s “label” layer on, and those for other scenes off. Now to create each label, make the appropriate layer for the current scene the active layer. Then choose the Text callout tool. The secret is that if you do not po…

Sketchup.active_model.add_note(‘Hello World’, 0.1, 0.1)

Thanks all !
I was looking into entities documentation. Tehe following code need to be complete but works for me.

  def createOrUpadteNote(newName)
    entities = @model.entities
    textes = entities.grep(Sketchup::Text)
    if textes.length > 0
      textes.first.text = (createOrUpadteNote)
    else
      @model.add_note(createOrUpadteNote, 0.1, 0.1)
    end
  end

Don’t you want newName not createOrUpadteNote in the two places where you set the text? As written, you have an endless recursion. Also, you have a built-in assumption that the only reason there will be any Text Entities in the model is that you have added them as notes.

if text_obj.point.nil? && !text_obj.has_leader?

Yes it’s a mistake due to translation “createOrUpadteNote” should be replace by “newName”

and
if text_obj.point.nil? && !text_obj.has_leader? is better
