Web dialog on a Mac

jolran

Are you using dialog.set_file ?

htmlset = File.join( File.dirname(FILE), "somehtml" )
dialog.set_file( htmlset )

I think that is one of the many recommendations.
Also do a platformcheck and set dialog to modal.

RUBY_PLATFORM =~ /(darwin)/ ? dialog.show_modal() : dialog.show

It's difficult for anyone to tell without some code I guess.

At least you have something to try out I have not yet done any dialogs for Mac so I couldent tell for sure if that works..

No, there is no special option you have to set. However, you do have to be careful about the fact that javascript runs asynchronously on the Mac but not on Windows. This can cause a host of problems. One of the most common is that an onload event callback from the HTML body will not work, you have to use a script element as the last thing in the body.

Take a look at TT's writeup https://github.com/thomthom/sketchup-webdialogs-the-lost-manual first to make sure you aren't doing something known to be wrong.

Thanks for the feedback,
I'll try some of your ideas. I did know about the unload, but thought I'd taken care of that with a message back to ruby to let it know the DOM was loaded.

Paul.

What triggers the message? It could be that due to async timing it is never delivered!

All,
I'm still having trouble despite reading the articles and trying to incorporate the advice recommended. Most of the 'examples' seem to stop at demonstrating that the behavior is different between operating systems. I just want to have a form send back it's data. I'm presuming that this is to do with the asynchronicity on the Mac. The submit button in the form doesn't run make it back to Ruby at all and the normal button works for one option, but not multiple options.

Here is the Ruby example code:

@d = nil
@d = UI;;WebDialog.new("Test", true, "", 800, 800, 200, 200, true)

htmlset = File.join( File.dirname(__FILE__), "test.html" )
@d.set_file( htmlset )

#set the callback for the radio buttons
@d.add_action_callback('food') { |dialog, params|
    puts '>> Food; ' + params
    @d.execute_script('send_radio_data();')    #return control back to JS?
}

@d.add_action_callback('animal') { |dialog, params|
    puts '>> Animal; ' + params
    @d.execute_script('send_radio_data();')    #return control back to JS?
}

RUBY_PLATFORM =~ /(darwin)/ ? @d.show_modal() ; @d.show

Here is the HTML example code:

<html>
    <body >
        Multi-Platform WebDialog form submission test<br>
        
        <form name="stuff" onsubmit="submitbutton();" method="post">
            Favorite Food;<br>
            <input type="radio" name="food" value="Pizza">Pizza<br>
            <input type="radio" name="food" value="Hotdogs">Hotdogs<br>
            Favorite Animal;<br>
            <input type="radio" name="animal" value="Cat">Cat<br>
            <input type="radio" name="animal" value="Dog">Dog<br>
                        
            <input type="button" value="Submit by Button" onclick="buttonpress()">
            <input type="submit" value="Submit by Submit">
        </form>
        
        <script>
            function call_ruby( callback_name, message ) {
                location = 'skp;' + callback_name + '@' + message
            }
        
            function send_radio_data(field) {
                //Get the field data
                var ps = document.getElementsByName(field);
            
                for (var i = 0, length = ps.length; i < length; i++) {
                    if (ps[i].checked) {
                        // Send the value back to SketchUp
                        call_ruby(field, ps[i].value);
                        // only one radio can be logically checked, don't check the rest
                        break;
                    }
                }
            }
        
            function sendformdata()
            {
                send_radio_data("food")
                send_radio_data("animal")
            }
        
            function buttonpress()
            {
                alert("Doing Button Press Send");
                sendformdata();
            }
        
            function submitbutton()
            {
                alert("Doing Submit send")
                sendformdata()    // Never gets ran
            }
        
        </script>
    </body>
<html>

If someone could put me out of my misery and help me correct this it would be much appreciated.

Sincerely, Paul.

(1) The button is just a button. Use onclick= instead of onsubmit=

(2) You are missing ; at the end of some JS statements. Try using a syntax checker like JSLint to check your code.

Ok I see a major booboo.

location is an attribute of the window object.

... so in your call_ruby() function, it needs to be:


            function call_ruby( callback_name, message ) {
                window.location = 'skp;' + callback_name + '@' + message;
            }

Thanks for the replies Dan,
I'm still having issues, but I'll keep tinkering =P.

Ok,
I've got it!! I made a few design decisions which should be reasonably documented in the code, but I've enclosed a fully working example below for submitting forms that works on a Mac and a Windows system.

The example below presents a single form with a radio buttons and checkboxes and after selecting them how you desire and hitting submit all of the settings are sent one by one. To get around the asynchronous/synchronous problem, I essentially have message passing between Ruby and JavaScript to force sending one option at a time (making both Operating Systems act asynchronously) from a options list. It should be quite easy to extend from here.

Here is the HTML/JavaScript Code:


<html>
    <body >
        Multi-Platform WebDialog form submission test<br><br>

        <form name="stuff">
            Favorite Food;<br>
            <input type="radio" name="food" value="Pizza">Pizza<br>
            <input type="radio" name="food" value="Hotdogs">Hotdogs<br>
            <br>Favorite Animals;<br>
            <input type="checkbox" id="a_cat" value="a_cat">Cat<br>
            <input type="checkbox" id="a_dog" value="a_dog">Dog<br>
            <input type="checkbox" id="a_squirrel" value="a_squirrel">Squirrel<br>
                
            <input type="button" value="Submit" onclick="sendformdata()">
        </form>
        
        <script>
            var options = {};   // object that stores all of our settings
            
            //Sends a mesage to SU / Ruby
            function call_ruby( callback_name, message ) {
                window.location = 'skp;' + callback_name + '@' + message;
            }
        
            //Add a checkbox value to the options object
            function add_checkbox_data(var_str) {
                if (document.getElementById(var_str).checked) {
                    options[var_str] = "1";
                } else {
                    options[var_str] = "0";
                }
            }
        
            //Add a radio button value to the options object
            function add_radio_data(field) {
                //Get the field data
                var ps = document.getElementsByName(field);
            
                for (var i = 0, length = ps.length; i < length; i++) {
                    if (ps[i].checked) {
                        // store value in our object
                        options[field] = ps[i].value;
                        // only one radio can be logically checked, don't check the rest
                        break;
                    }
                }
            }

                    delete options[setting];
                    call_ruby(setting, value);
                } else {

                //The checkbox options all have unique names to simplify storage in 'options' receipt at the SU end (more callback handlers needed though)
                //Could have concatenated all check options into a string, sent them as a single submit and parsed the string at the SU end too
                add_checkbox_data("a_cat");
                add_checkbox_data("a_dog");
                add_checkbox_data("a_squirrel");
                
                //Send the first setting to SU, the callbacks will get the rest
                send_setting();
            }

        </script>
    </body>

Here is the Ruby Code:


@d = nil
@d = UI;;WebDialog.new("Test", true, "", 800, 800, 200, 200, true)

htmlset = File.join( File.dirname(__FILE__), "test.html" )

#set the callback for the radiobuttons

Hi Paul,

I'll give it a run later...
I've been trying to tidy up my own version to see if it would be of any use, but you beat me to it...

I'll post it anyway, for your perusal, and maybe see if it works on a PC [I don't have one]

I wanted to use only ruby and the least 'vanila' js to do all the sorting. To achieve this I use a common id(+digit) for each element, then a ruby range loop collects them...

Let me know if it seems sensible?

The reference to the dialog object needs to be an instance var @dlg, or else Ruby's garbage collection will sweep up the local var inside the method when it returns.

Ie.. the dialog will close by itself, and be destroyed. (or you can return the dialog object at the end of the method, and let the caller have the responsibility to hold the object reference.)

driven

hi dan

it's a quick[well not so quick] lash-up of a few concepts I've had on the back-burner for far to long...

so there is room for improvements in the coding, so fire away...

I could never see the need for the hidden field to hold the js values, when ruby could collect them directly for itself?

I'm just adding to it to bounce back some interactive ruby, i.e. Sketchup as server, which has also been on the bb...

I guess that's what xmas is for...

BIG ?? does it run on Windows...

john

Dan Rathbun

Without even trying I can tell you we will see the dialog for a second and then POOF it will be gone.

But if you return dlg as the last line of the method,...

and then call it using a reference assignment like:
my_dialog = js2ruby()
it WILL work because Ruby will hold a reference to the dialog object.

driven

so why does it always work on a mac...

never had one vanish?

I can even add a bunch of GC.start 's and it's stay's... just tried it...

just curious...

john

Dan Rathbun

Specifically I do not know.

Generally the OSX GUI is different from the MS Windows GUI.

I have also been experimenting with web dialogs. This works with Windows 7 and sketchup 7,8 and 2013.

Hopefully someone with a MAC can try this and see if it works in Safari.

I have Chrome, IE11 and Firefox installed. The code works with these Browsers but only if I rem out the line that references sk

This file adds a menu Item under Plugins called "Web Dialog Test"

looks like this in SU, and works
but you do need a version of

    # then set_html or file/url if separate...
    @dlg.set_html html
    if( (RUBY_PLATFORM =~ /darwin/i) )
    @dlg.show_modal
    else
    @dlg.show
    end #if

Garry K

Thanks

I can easily add that.

When you clicked "Ok" button did you get a list of Control Id's and values?

driven

you mean this?

pre-setting the size [webDialog] is better as well.

john

Garry K

Yes - that is what I meant.

Pre-setting the size would help on Windows for the first time it is run. But after that the window uses the last known size and position that the user set it to.

Does it work differently on the MAC?
