Recognising Sketchup

[chrisglasier]

I am trying to get a web dialog to recognise it has been opened by a sketchup plugin. Is there some standard Ruby like window.opener in Javascript. (The html file in the web dialog can be opened and used with other applications provided the Sketchup switch = 0).

Any guidance gratefully received ... Thanks

Sorry, I'm not sure what you are trying to do.

@dialog = UI.webDialog.new
@dialog.show()
@dialog.visible? # returns true if the dialog is visible

This will tell ruby that the dialog is open, but I don't think that's what you were asking. What do you need to accomplish?

EDIT: After a few more readings, I think I may have figured it out You could use @dialog.execute_script(javascript_goes_here) that could set a js variable to say the html was opened from SketchUp.

Many thanks ... apologises for the many readings!

I tried a function call as shown here:

#Ruby

@dlg = UI;;WebDialog.new("Nameset", false,"",300, 205,0,0,false)
      	     
	subDir = "D;/Nameset3/"
	fileName = "Nameset3 machine.htm"
	
@dlg.set_file File.join(File.dirname(__FILE__), subDir+fileName)
	
@dlg.execute_script("startSketchup()") 

//javascript

function startSketchup(){
sketchup=1
productsRun()}    //picks up and positions skp components 

The dlg.execute_script works fine from the Ruby console but not directly. Obviously I am missing something - but what?? I tried a add_action_callback but that causes much aggro with non-Sketchup use, and I quickly gave up trying to get one to work.

Further advice much appreciated.

This is kinda a hack, but in javascript window.external will throw a "not implimented" exception under Sketchup but not under IE or Firefox.

You could catch that exception and set a flag.

Thanks for the responses. I have persevered with the dialog.execute_script because this seems right and proper, but I think at least for the moment I have to fall back on the exception business - probably try ... catch rather than window.external as I use that a lot during development stages.

Thanks again.
