Palette Sample not working?

Anonymous — Wed, 05 Apr 2017 17:23:59 GMT

I'm not sure what I've done wrong, but I can't seem to get the palette sample to work. I've made an add in from the code here:http://help.autodesk.com/view/fusion360/ENU/?guid=GUID-c97b8ed2-e1da-11e6-af4c-3417ebc87622

I didn't make any changes, but when I try to use the 'send info to Palette' button I get the error pictured. When I click the 'click to send info to Fusion' button on the palette nothing happens. What could cause this if I didn't edit the sample code?

Thank you for reporting this. I can reproduce it and have found the problems. The good news is that the problem isn't with Fusion but was with the sample code. I made a couple of last minute changes as I was publishing it and apparently I broke it. I've fixed it in the help system so it will be available with the next Fusion update. Until then here's the updated html and py source.

palette.html

<!DOCTYPE html>
<html>
    <head>
    </head>
    <body>
        <p id='p1'>Click the button below or use the "Send info to HTML" command in the ADD-INS panel.</p>
        <button type='button' onclick='sendInfoToFusion()'>Click to send info to Fusion</button> 
        <br /><br />
    </body>
    <script>
        function sendInfoToFusion(){
            var args = {
                arg1 : "Sample argument 1",
                arg2 : "Sample argument 2"
            };
            adsk.fusionSendData('send', JSON.stringify(args));
        }
        
        window.fusionJavaScriptHandler = {handle: function(action, data){
            try {
                if (action == 'send') {
					// Update a paragraph with the data passed in.
					document.getElementById('p1').innerHTML = data;
				}
				else if (action == 'debugger') {
                    debugger;
				}
				else {
					return 'Unexpected command type: ' + action;
                }
            } catch (e) {
                console.log(e);
                console.log('exception caught with command: ' + action + ', data: ' + data);
            }
            return 'OK';
        }};
    </script>
</html>

Hello,

I tried to run Palette Sample on my Windows PC, but it doesn't work as expected. Palette Dialog doesn't show up.

I have read related topics on this forum, but so far no success. The script show only small dialog with 'Stop addin' message.

Is the sample code from current (January, 17th, 2019) this

Programming Interface/Sample Programs/User Interface/General/Palette Sample web page updated and correct? Or should I use the code from the post above?

The .html file is in the same directory as the .py code. Anyhow I tried to trace the python code. I set a break point into the ShowPaletteCommandExecuteHandler.notify. It looks like the code doesn't even reach the method. (the handler is never called)

How is the correct string-path for the html file? Relative path works? How to write absolute path?

Is for example this correct on Windows PC: 'D:\\GitHub\\Fusion360\\Scripts\\ApiSamplePalette\\palette.html' ?

Thank you
