Double Line 2 (dline.rb update)

Jim

I made some (hopefully) improvements to Didier's dline.rb double-line & wall tool. Mostly the changes are to improve user interaction with the tool.

Tab key brings up the options dialog, otherwise the previous values are in effect.
Values are saved between uses, and between sessions.
Options dialog and Measurements display/accept Model Units.
Can enter the Width in the Measurements (VCB) upon activation.
Right-Click empty space to finish the line. (Same as Enter key.)
Fixed line color wrt inferences, and fixed inference locking.
Add a ConstructionPoint to start of line for later inferencing (deleted upon completion.)
Fixed clipping.
Wrapped code in module namespace.
Renamed menu to Double Line 2

This file is meant to replace dline.rb file if installed, but can co-exist alongside dline.rb.

Thank you Jim.

Jim

Sure; although there seems to be some problems with the creation of the geometry in some cases. I haven't looked at that part.

I also noticed that you use the onKeyDown method to get 'TAB'... this usually fails on a MAC as TAB is screwed on key-down... the recommended way is to use

def onKeyUp(key, repeat, flags, view)
    if key==9 or key==15 or key==48 ### TAB =9 for PC, MAC 15/48 for some locales ?
       ###

Note how I also have some other keys mapped as in some locales/MacOSs it seems that '9' isn't Tab

Is there no VK_* constant for tab that would be correct for the platform it runs on?

No. There should be but it's missing...
It's a simple matter to always check for 'key-up' if using 'Tab' though

Don't work on the V6 (pc)
Drawing lines are good but
Walls are not drawn when Enter pressed


Error; #<ArgumentError; wrong number of arguments(2 for 1)>

This is the same problem I mentioned with DrawHelix and model.start_operation taking a second argument after v6.
Unfortunately in this tool it is NOT coded to allow use in v6 at all... BUT here is the fix...
In a copy of the script in the v6 folder find the two lines reading [one might be in French ]
Sketchup.active_model.start_operation("Double Line", true)
and edit the text so there is no 'true' thus
Sketchup.active_model.start_operation("Double Line")
Now it will work in v6 [this will also work in v7/8 but is less efficient in refresh of display terms]
I think a relatively idiot proof way of doing a start_operation that is optimized for all versions is

begin
  Sketchup.active_model.start_operation("Double Line", true)
rescue
  Sketchup.active_model.start_operation("Double Line")
end

That is, it tries to start an operation with a second argument flag set [best for most v7/8 uses] BUT if it fails then it does one without the flag - e.g. v6..........

No one really responded when I asked the question about begin-rescue clause with start_operation. Probably a poor choice for a topic sentence on my part.

Great minds think alike... fools never differ...
I agree that this begin-rescue way is less prone to error like your .version v. .version_number typo which screwed Pilou's v6...

I can't get my Mac to print out the key code for a Tab?

For onKeyDown it won't as Tab on Mac doesn't fire onKeyDown
But with onKeyUp it should return 9
BUT note that some locales/MacOSs can return 15 or even 48 for Tab...
I use this

### Type 'keycode' in the Ruby Console...
class TIG_KeyCode
  def activate
    @key=""
    puts "TIG's Non-Shortcut Keycode Reporter.\n"
    puts "Click in the Main Window outside of the"
    puts "Ruby Console then Press Non-Shortcut Keys..."
  end
  def onKeyDown(key, repeat, flags, view)
    @key=key.to_s
    puts "You Pressed Keycode = "+@key
  end
  def onKeyUp(key, repeat, flags, view)
    @key=key.to_s
    puts "You Released Keycode = "+@key
  end
  def deactivate(view)
    puts "You have pressed a Shortcut Key...\nExiting."
    return nil
  end
end#class
def keycode()
  Sketchup.active_model.select_tool(TIG_KeyCode.new)
  puts ""
end#if

Well, that's rather a pain, not to mention bug-ish.

Is it reported?

Y'know... I don't recall... BUT I have been avoiding using onKeyDown for TAB-key for MAC compatibility for ages by using onKeyUp key==9 etc... I even teach it to my students
I've search my usual haunts... and not found a link but there must be something somewhere as I can't have dreamed up the problem alone...
It seems to have been raised around here http://forums.sketchucation.com/viewtopic.php?p=273542#p273542 Jeff was also involved and Fredo? ...
