Passing arguements

honoluludesktop

Can Class My_Tool have the following form? Class My_Tool(menu_selection). If not how can I pass menu_selection, that are outside the Class to it? Hope my question makes sense.

thomthom

class My_Tool
  def initialize(selection)
    # do something 'selection' is now a variable
  end
end

my_very_own_tool = My_Tool.new(menu_selection)

Thanks, Tom. Is this OK, and safe to use?

Class My_IDX_PointTool

	def initialize(menu_selection)
		@sel = menu_selection
	end
	
	def program
		#do somenting with menu_selection
		puts @sel
	end
	
end

thomthom

Yes. You got it!

I use this also:


class My_Class

def option1(arg, arg2, etc)
puts arg
my_etc(etc)
end

def option2(arg, arg2, etc)
puts arg2
my_etc(etc)
end

def my_etc(etc)
puts etc
end


end

arg = Sketchup.active_model.selection
arg2 = Sketchup.active_model
etc = [1,2,3]

tool_object = My_Class.new

plugins_menu = UI.menu("Plugins")
plugins_menu.add_item("Option 1") {Sketchup.active_model.select_tool(tool_object.option1(arg, arg2, etc))}
plugins_menu.add_item("Option 2") {Sketchup.active_model.select_tool(tool_object.option2(arg, arg2, etc))}

That is also a way to use the same tool object each time the tool gets called, instead of instantiating a new one each time. And I point diretly to a specific method within the class when I start the tool. It could also be done with a line like this:

Sketchup.active_model.select_tool( My_Class.new.option1(arg,arg2,etc)

See how that instantiantes a new tool object each time its run, but it also points directly to a method of the class.

Hope that made sense,

Chris

Guys, thanks for the help. Chris, I will look very carefully at your example.
