[Plugin][WIP] Layers Panel - Dev

jiminy-billy-bob

Thanks a lot TT for your answers and advice ! I'll take a look at all of this.

Safest thing is to keep everything in your own namespace.

It thought I did. Can you show what piece of code is wrong ?

Is there a reason for that ? It's better that way ?

What's NOT working :

[list][*]From ruby to WebDialog : Real-time rename layer, hide/show layer. Due to limitations of the LayersObserver. I'll need to detect changes either when the webdialog gets focus (But you won't have real-time visual feedback), or every xxx ms.

Actually, it may work. Not with the LayersObserver, but with the EntityObserver, which detects hide/show and rename events.

The snippet that modified Sketchup::Layer .

Because with double quoted strings you can do interpolation - like this "Hello #{some_variable}" where as in single quoted you cannot.

Ho, ok. I assumed TIG's work was clean. But this snippet is actually 4 years old, I guess he wasn't aware of that back then.

Thanks !

thomthom

Basically, any modification of the Ruby or SketchUp API classes is bad practice. So are global variables.
There's some old code lingering around from the days before people started to figure out what best practices where.

jiminy-billy-bob

If I understand ruby classes correctly, I have to rewrite the code, right ?
I can't have something like layer.delete() while keeping it in my own namespace. Am I right ?

thomthom

Correct. Make a method under your own namespace that takes the layer as an argument.

Not as pretty, but it'll work and it will be safe from clashing with anything else.

jiminy-billy-bob

Ok, here is a new version.

Added Toolbar and menu item (Window > Layers Panel), with toggle
Change things you TT told me : Undo, +operator, filename...
Deleting layers now work properly. The method is wrapped in my namespace. When a layer has geometry, you are promped to choose to delete the content or move it to the default layer.
Added a menu for some options. For now you can only purge layers.
I also don't have bugsplats anymore. Don't know why exactly... If people get some, please tell me.

Still no saving, I'm getting used to ruby before attacking this big piece.

Also, I can't get my WebDialog callbacks to work if the dialog is not in a global variable. I tried local, instance, and class variables, nothing works. What am I doing wrong ?

Layers Panel 0.02.rbz

jiminy-billy-bob

Hmm, so a class variable in a class ? That makes sense ^^
Thanks for the tip, I'll try that.

I hope that naming the Class "TEST" didn't confuse you since the class name doesn't have anything to do with the variables (var test = true) in html.

I guess what i am trying to say is that the "var test" in html has nothing to do with "Class TEST" in ruby.

Not sure if you are confusing them both but just in case.

Note: Will edit the name of the class on my last post to "PLUG".

Hi,

If you want to change something from ruby to web-dialog you can do this...

In Html & Javascript:


<html>
   <head>
      <title>Example</title>	
   </head>

   <body onLoad="startup(), stopwatch(this.value);">

   </body>	
</html>

<script>
var delay = 1000/5 ; #this will update 5 frames per second
var timerID = false ; 

var test = true ;  #this is the value you will change from ruby


function startup() {
nextFrame();
}

function stopwatch() {
SD=window.setTimeout("stopwatch();", 100);
}


function nextFrame() {

   try {

      test = test


      setFrame() ;

      top.timerID = self.setTimeout("nextFrame()", delay) ;

   } //try

   catch (e) { 
      alert("push_frame; " + e) ; 
   }

} //nextFrame()


function setFrame() {
url = 'skp;push_frame@' ;

   url += '&test=' + test;

window.location.href = url ;
}

</script>

In Ruby:


module SU_PLUG
   class PLUG

      @@model = Sketchup.active_model ;
      @@dir = File.dirname(__FILE__) # this plugin's folder
      @@path = File.join(@@dir, '/Folder/')
      @@dlg = "test.html" ;
      @@test_dlg = nil ;


      def initialize()
         @test_1_file =  File.join(@@path, @@dlg) 

         if @@test_dlg == nil
             @@test_dlg = UI;;WebDialog.new("Test", false, "Test", 300, 600, 70, 95, true) ;

            @@test_dlg.add_action_callback("push_frame") do |d,p| 
               push_frame(d,p) 
            end
         end

         @@test_dlg.set_size(300, 600) ;
         @@test_dlg.set_file(@test_1_file) ;
         @@test_dlg.show() ;

      end #def 


      def push_frame(dialog,data)
          params = query_to_hash(data) ;  # parse state information 

          if params['test'].to_s == "true"  #Example of a  condition.

             change = false

             script = "top.test= " + change.to_s + ";"    #this sets test=true to test=false
             dialog.execute_script(script);   #this execute it
          end
      end #def


      def unescape(string)
      if string != nil
      string = string.gsub(/\+/, ' ').gsub(/((?;%[0-9a-fA-F]{2})+)/n) do
      [$1.delete('%')].pack('H*')
      end
      end
      return string
      end #def

      def query_to_hash(query)
      param_pairs = query.split('&')
      param_hash = {}
      for param in param_pairs
      name, value = param.split('=')
      name = unescape(name)
      value = unescape(value)
      param_hash[name] = value
      end
      return param_hash
      end #def


   end #class
	
end #module

Hope this helps and again very good plugin!

Ruby uses 2 space indentation. HTML & Javascript 4 space indentation.
NOTHING uses 3 or odd number spaced indents !

See this other post: Re: Webdialog scripting issues

Use local vars INSIDE methods as temporary variables. They get garbage collected when the method ends.

Use @@vars INSIDE modules or for class-wide access.

Use @vars in class instance methods (define and init them inside the initialize method.)

jiminy-billy-bob

Thanks a lot, I'll try that.

Only Python require a certain indentation - Ruby, HTML and JS doesn't care. It's just coding convention within the team/project you're working with.

Please, don't ever give up on this plugin, it'd save my life! I wish I could help

jiminy-billy-bob

I won't give up ! I just don't have time curently. I will at the end of july.
No worries

Krisidious

just posting so I'll get updates on this thread.

jiminy-billy-bob

I made another thread to discuss the behaviour of the plugin : http://sketchucation.com/forums/viewtopic.php?f=323&t=52225

Feel free to participate

Thanks for your present！This is a great plugin, but I have a problem，I created a layer group，which contains a number of layers，but when I restart the plugin Panel，everything was back to the way they were，the group disappeared， the new layer still exist。
