greatly appreciated!

Note to self: Update Async vs sync Communication
It's not .execute_script that's async - it's the Javascript callback using the skp: protocol

Jim

Thanks for doing this Thomas.

Finally, there is a difference in the way that the Mac boots up SketchUp that you should be cautious about: there is no Sketchup.active_model when the Ruby scripts are first loaded. So if your script is making changes to the active_model at load time, it will not work on the Mac. The answer? Ensure code that references the active model is part of a UI event handler, responding to the user selecting a tool or a menu item. You can also use an AppObserver to get a callback whenever a new model is opened, at which point it's safe to talk to the active_model.

I didn't see this anywhere. I don't remember where it comes from.

How about marking topics and posts with [WebDialog]?

Good work - most generous with your time.

I hope that people will point out things that are not clear. Writing has never been my strongest skill, actually - its one of my poor, so please point out the weaknesses.

Thank you!

Hi Thom,

thanks for sharing this really usefull information!

Just as a side note:
We have found a bug, which cuts decimal value sent from SketchUp to WebDialog (only in SU6 on Mac). If we i.e. want to update the value of some input box like this:
web_dialog.execute_script("updateInputBox('varName', '12,345')")
only 12 is shown in the varnName inputbox, everything behind (and including) comma is being cut off. But it works in SU7 on Mac and on both, 6 and 7 versions of SU on Windows.

thomthom

Ah, is that whatæs being mentioned in the release notes: http://code.google.com/apis/sketchup/docs/releases.html

@unknownuser said:

Fixed Mac support for WebDialogs execute_script

WebDialog.execute_script('alert("Bug is Fixed!")');

Does it work if you escape the comma? If not, replace it with another character?

Jernej Vidmar

No, escaping doesn't seem to help. Only way to pass the float value is to write it using dot (1.12) not comma (1,12)...
For now we have not found a workaround, but we intend to make some more tests to see if the problem can be bypassed.

thomthom

I wonder, if you make a special receiving javascript function, and send all command base64 encoded to that function and have it decode and eval it..?


# made up methods - haven't checked the real methods
jscall = base64encode("updateInputBox('varName', '12,345')") 
WebDialog.execute_script("decode(#{jscall})");


function decode(base64str)
  eval(decode64(base64str));
end

You won't be able to use HTML5 in webdialogs - not until IE adds support for it. Think I read somewhere that they where adding support for it in IE9. Being able to use CANVAS sure would be nice.

I am using excanvas http://code.google.com/p/explorercanvas/ which provides a canvas object in IE.

That's very interesting! I've been wanting for a good solution to dynamically draw graphics in webdialogs. Probably be of interest for Whaat as well... ...thinking Profile Builder...

Jim

And just to have more options, there is also chrome frame.

Yea, but this requires the user to install a browser plugin.
explorercanvas is a simple JS library which the developer includes in the project without the user ever having to install any browser extension. That's what's appeal to me.

Pout

this seems to be very interesting
Have to dig into this.

One thing driven discovered was that if for some reason there is whitespace as here -

cmd = "fImportReturn('#{array}');"
@dlg.execute_script (cmd)

instead of

@dlg.execute_script(cmd)

it is OK on PCs but not Macs. This maybe of interest to coders who use this style (Jim).
