Web dialog on a Mac

tt_su · 6 Jan 2014, 14:30

A bit late to the party, but if you just need simple controls and theming then you can try out SKUI: https://github.com/thomthom/SKUI/wiki/Quick-Overview

Takes care of all the WebDialog stuff and exposes only a Ruby object model to the GUI elements.

Interesting idea - but what I need goes a bit above this. I want to add into the web dialog a jquery call using JSON to query a MySql database on my website. I will use PHP for the server portion.

In any event - good knowledge of CSS, HTML and JS is good to have.

Well, call me frustrated.

The simple test application worked with the Mac. But the complete Stair Maker plugin does not work with the Mac.

I've added instance variables for the web dialog.
I've stored the text that Ruby passes over to the Web Dialog as an instance variable and built prior to calling the web dialog.

I must be missing something. The overall strategy now is:

if ( document.addEventListener )
document.addEventListener( "DOMContentLoaded", ready, false );
else if ( document.attachEvent )
document.attachEvent( "onreadystatechange", check_ready );

When the DOM is loaded it makes a call back to ruby with text == 'loaded'.
ruby then passes the string over to the web dialog for processing.
When the user clicks the button the web dialog traverses the DOM and peels out all of the text for input controls and builds up a single string. Then makes a call back to ruby and closes the dialog.

One question I have is can Safari handle making a call to execute script from within the ruby call back. Or do I need to consider turning this into a state machine?

Yes, WebKit can handle making an execute_script call from within a Ruby skp: callback. But you have to be careful what the script does. On the Mac, Ruby will wait synchronously for javascript to return, but javascript will not wait for Ruby, so you have to be careful. Sometimes a state machine or similar is the only solution.

A picky point we Mac'ers need always to reinforce: WebDialog uses the WebKit library, not Safari.

Garry - Where do I get the updated version? I can't find a download link...

It is on the stair maker thread

Steve,

In ruby the last statement in the callback is
dialog.execute_script( script )

In the web side there is a parsing routine plus the populate_drop_down function


function from_ruby( data )
{
	var element;
	var pair;
	var pairs = data.split( '&' );
	var count = pairs.length;

	for ( var i = 0; i < count; i++ )
	{
		pair = pairs[i].split( '=' );

		element = document.getElementById( pair[0] )

		if ( element.type == "select-one" )
		{
			if ( pair[1].indexOf('|') == -1 )
				element.selectedIndex = pair[1];
			else
				populate_drop_down( element, pair[1] );
		}
		else if ( element.type == "text" )
			element.value = pair[1];
		else if ( element.type == "checkbox" )
			element.checked = pair[1] == '1';
	}
}

It almost seems like the DOM isn't really ready to receive updates.

<head>
<script type="text/javascript">
var xmlHttp = null;

if ( document.addEventListener )
	document.addEventListener( "DOMContentLoaded", ready, false );
else if ( document.attachEvent )
	document.attachEvent( "onreadystatechange", check_ready );

function from_ruby( data )
{
   xmlHttp = new XMLHttpRequest();
   xmlHttp.open( "POST", "http://cabmaker32.com//stairmaker_service.php", true );
   xmlHttp.onreadystatechange = handleRequestStateChange;
   xmlHttp.send( data );
}
function ruby_call( text )
{
   window.location.href = 'skp;ruby_callback@' + text;
}
function handleRequestStateChange()
{
	if ( xmlHttp.readyState == 4 )
	{
		if ( xmlHttp.status == 200 )
			ruby_call( xmlHttp.responseText );
		else
			ruby_call( 'error' );
	}
}
function check_ready()
{
	if ( document.readyState === "complete" )
		ready()
}
function ready()
{
	ruby_call( "loaded" );
}
</script>
</head>

this is all I can grab before I get the service denied message....

I downloaded the rbz from the curved stairs topic hoping I could help, but all I get is this error dialog...

The first time I click "Stair Maker", a blank dialog window pops up at upper left and the Ruby Console displays:

show 1
loaded 1
cb1 complete

then after a moment that window disappears and the error message box appears. At that point the console adds:

closed 1

And I also notice that four new layers have been added to the model: Handrail, Risers, Stringers, Treads.

When I click ok on the error message box, the console adds:
loaded 2
cb2 complete

and this web dialog appears:

If I click the Load button, any values I have typed into fields are reset and the console again adds:
loaded 2
cb2 complete

If I click the OK button, the web dialog closes and the console adds:
closed 2
cb2 complete

If I then select Stair Maker again, it immediately pops up the error message, without displaying the first three console messages about "1".

Since your Ruby is scrambled, I have no idea what is happening on that side, but does this behavior correspond to what you expect? If not, what exactly is the problem?

I noticed that your HTML has a bogus <body"> element. It appears that the WebDialog ignores it.

Steve,

Ok we are getting somewhere. Can you tell me if the input boxes and drop downs were populated before you clicked on the "Load" button.

"user not on file" at the top of the dialog is correct for an error code -21.
I believe that if you edit the defaults.txt file and stick in the user and password from registering with my web site that you would be able to create a circular stair.

I will temporarily make changes to the web service so that you don't have to edit the defaults.txt file. And I am going to rem out the extra messages and drop the load button.

I'm not getting as far as steve...

from WebKit WebInspector inside SU...

[Error] SyntaxError; Expected token ')' (file;///, line 1)
> ready
< function ready() {
	ruby_call( "loaded" );
}

Garry K · 7 Feb 2014, 01:33

Did you update the defaults.txt file or leave it as 'user' and 'test'

Yes, Garry, all the fields in the dialog were populated when it first appeared, including drop-down lists.

I registered on your site, edited the info into the defaults.txt, and voila, got this:

hmm.. strange.. a few of us are testing in the stairMaker thread and not getting that far.. we're using mavericks and 2013make or su8.. what OS / SU are you testing on?

[EDIT] just tried it on su8pro / mavericks and i'm still getting a window with all blank fields/menus.. i'll try it on my other computer running lion in an hour or so.

jeff hammond · 7 Feb 2014, 07:00

just tried it on Lion (os x 10.7.5) with su2013 and su8.. i'm getting the http error & cannot reach web service error..

i'm on the same wifi network as my mavericks laptop using the same 1.0.6 rbz.. i checked and double checked my username & pword were edited properly in the txt file..

the mavericks computer connects and the lion macpro doesn't.

[just in case, i had some OS updates which needed install on lion.. a security update and a java update.. installed those, repaired permissions, rebooted... same problem.. but at least i got that computer up to date ..or as up to date as 1,1 macpro can be without hacking it ]

That was on SU 8 Free, MBPr, Mavericks.

I just tried using SU 2013 Make (still on Pro trial period) on MBPr, Mavericks, and that worked too. This was a clean (no other plugins) install of 2013 Make, but for my previous test on SU8 Free I hadn't disabled anything.

For me, 1.0.6 was the first installation of the stair maker. Any chance previous installs left something behind that is interfering on your computer?

Another thought - could this be a race condition? My MBPr is relatively fast, and once before driven and I got different results on another script evidently because his machine was slower than mine...
