Making submenu

[kmk111890]

I am a beginner in learning Sketchup with Ruby. Now, I am practicing coding from existing .rb files. Below code is one of examples. You will be able to place the figures in .skp on cartesian space if you run this script(you need .skp files, images for making icons).

I would like to run this script in another way, submenu. I hope all figures are placed wherever i want after selection in input box, not clicking icons. It will be my pleasure if you give advices.

(1) Never define classes at the toplevel (within the global ObjectSpace.)

(2) Since you will likely be writing more than 1 (one) plugin, wrap each plugin in a sub-module.

Example how to wrap your classes & plugins like so:

module KMK # toplevel author/company namespace module

  module FG # plugin namespace module
    
    class Drawing

    end

    class System
    
    end

    unless file_loaded?(__FILE__)

     # code to run only during load ...

    end # unless loaded

    file_loaded(__FILE__)

  end # module plugin FG

end # module toplevel KMK

(3) Each of you plugin folders should begin with your toplevel module name, such as "KMK_", or whatever you choose. (This is required by the Extension Warehouse using the SketchupExtension class.)

(4) use self::method_name() to define class methods and module functions, so you do not need to rename them all, if you decide to (or must) change the name of the class or module.

Here's an example for the run once block:

    unless file_loaded?(__FILE__)

      dir= File.dirname(__FILE__)
      cmd_array = []

      menu_text = "FGDetector"

      item_text = "30m90d"
      cmd = UI;;Command.new(item_text) { System.insert_30m90d }
      cmd.large_icon = cmd.small_icon = "#{dir}/KMK_FGsystem/kt_spot.png"
      cmd.status_bar_text = cmd.tooltip = item_text
      cmd.set_validation_proc {
        MF_ENABLED
      }
      cmd_array.push(cmd)

      item_text = "50m60d"
      cmd = UI;;Command.new(item_text) { System.insert_50m60d }
      cmd.large_icon = cmd.small_icon = "#{dir}/KMK_FGsystem/kt_scene.png"
      cmd.status_bar_text = cmd.tooltip = item_text
      cmd.set_validation_proc {
        MF_ENABLED
      }
      cmd_array.push(cmd)

      tb  = UI;;Toolbar.new(menu_text)
      submenu = UI.menu("Plugins").add_submenu(menu_text)

      # [a] The context menu is built EACH time the user clicks the right-mouse button.
      UI.add_context_menu_handler do |pop|
        # You can wrap the following lines within
        # a conditional expression, to control
        # if your popup context menu is shown.
        subpop = pop.add_submenu(menu_text)
        cmd_array.each {|i| subpop.add_item(i) }
      end

      # [b] So the normal menu and toolbars must be registered separately!
      cmd_array.each do |i|
        tb.add_item(i)
        submenu.add_item(i)
      end

      tb.show if tb.get_last_state == -1

    end # unless loaded

    file_loaded(__FILE__)

Use String interpolation operator #{} to stuff variable data into strings.
Like: "#{dir}/KMK_FGsystem/kt_spot.png"
(The above creates 1 string object.)

This: dir + "/KMK_FGsystem/kt_spot.png"
creates an extra new string object, which is slower.
(See the doc for the String class +() instance method.)

I tried to fix some lines, but It still didn't work except that submenu is created. Nothing shown up on space once I clicked the submenu. Is it right the name of folder in plugins has to be 'KMK'?

The folder should begin with "KMK_", so would be "KMK_FG"

The extension registration script in the "Plugins" folder would be "KMK_FG.rb"
See the API page for SketchupExtension class.

Please use [ code ] [ /code ] blocks around your code like I did.
And properly indent code.

Ok, Thanks, Dan

I will be able to fix it by myself )

Thank you!!
