Hello,



When I run the paint example or a project with a Tpaint control I get a  "Your browser doesn't support canvas operation" and I've seen nothing on the subject in help. Sorry, I'm surely an idiot but what is "my browser" ? The default browser of my system (I changed it with Firefox and chrome without success) ? How can I allow canvas operation ?

If deploy my project on users system, with Chrome, Firefox and others, what will happen ? Will these not very expert in computer science users will obtain a "Your browser doesn't support canvas operation" ?

Regards,

Falcon

Paint.html (the output of Paint example) works in firefox, not at all in chrome (only a nice "elevate web builder" logo), and IE says "your brower doesn't support etc.".


I tested CHROME's HTML5 support with :

http://www.presse-citron.net/html5-test-une-page-pour-tester-la-compatibilite-de-votre-navigateur-avec-html

It obtained a 217/300 note ... so what is the problem ?

And how can I restore or change the EWB's html5 supporting capabilities ?

Falcon.

Ok, EWB web server is accessible via ewbsrvr.exe.

I beforehand uninstall/re-install EWB.

----> Same problem.

I ran ewbsrvr.exe, I saw nothing about HTML5 or canvas.

Life is nice ... Sun shines ... Computer science is a so interesting thing.

In the Paint Project - did you go into Project Options - and the Compilation Tab - and check the box Enable HTML 5 Functionality - before you compiled?

You can also see there is an HTML 5 (red shield) icon at the top of the Project manger that does the same thing - enable the HTML 5 compilation.

I tested the output from my web sever using Chrome as the client browser and it works fine in Chrome.

Like Walter said you need to enable HTML5 for the project - not sure why
it's not enabled by default as it should be.

In general if you start using HTML5 functionality you will need to build
in some checking in your code that user runs a compatible browser. You
will get an eror from EWB but it might not be what you want your users
to see.

IE is usually the culprit as HTML5 requires IE9 or later. Firefox and
Chrome auto update better so more likely to have latest version.

HTML5 option was set, "5" red icon is checked ----> same problem.
I unchecked compress output icon, "Line 1 error" message changed to "Line 19656 error" ...
If it can help !

Does EWB canvas capabilities are linked/based/dependent on IE's ones ?
(IE, on my system, refuse HTML 5 with the same error message as EWB).

Tim has the Paint App hosted on his Website ... when you run it from here does it work?

http://www.elevatesoft.com:8080/paint/paint.html

In IE you need to have the Allow Active Content to Run if you are just double clicking the paint.html file on your disk.

Walter

Walter, I updated IE8 to IE9 and now it works ...
As I had the feeling, EWB server is IE based, it is something like TWebBrowser's delphi component.

Thanck you for your help.

It is not EWB Server - it is the Browser - IE 8 does not support HTML 5 - IE 8 is very old.  Chrome and FireFox support HTML 5 too.  (I am talking about current releases.)

Glad you got it going.

Raul,

<< Like Walter said you need to enable HTML5 for the project - not sure why

This is fixed in the next build.  It was just an oversight on my part after
the HTML5/IE option was added.  The IDE now creates a project configuration
file with this option turned on when the paint/canvas example project is
installed via the Help menu option.
