Hello,

has anyone of you managed to display a SpiderBasic app in a WebViewGadget?

This one does not work (WebViewGadget remains empty):

Code: Select all

OpenWindow(0, 0, 0, 1000, 800, "", #PB_Window_SystemMenu | #PB_Window_ScreenCentered) 
WebViewGadget(0, 10, 10, 980, 780)

ReadFile(0, "C:\Temp\HelloWorld\index.html") ; a simple HelloWorld-App written in SpiderBasic
Html$ = ReadString(0, #PB_File_IgnoreEOL)
CloseFile(0)

SetGadgetText(0, Html$)

Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow

Unfortunately there is also no error message or anything similar.

Thanks in advance & best regards ... Peter

Did you create a subdirectory named spiderbasic with the following files inside?

<script type="text/javascript" src="spiderbasic/platform.js"></script>
<script type="text/javascript" src="spiderbasic/init.js"></script>
<script type="text/javascript" src="spiderbasic/dojo/dojo.js"></script>
<script type="text/javascript" src="spiderbasic/main.js"></script>
<link rel="stylesheet" href="spiderbasic/dojo/themes/flat/flat.css" />
<link rel="stylesheet" href="spiderbasic/dojo/dgrid/css/dgrid.css" />
<script type="text/javascript" src="spiderbasic/xdate.min.js"></script>
<link rel="stylesheet" title="Default" href="spiderbasic/themes/flat/window.css" type="text/css"/>

It is not a 'single file' application.

Yes, of course. I created the app with the "Create App..." - function of SpiderBasic.

In my case this does not produce a full directory.
All this was really needed:

\Test01\spiderbasic\dojo\
\Test01\spiderbasic\dojo\cbtree\
\Test01\spiderbasic\dojo\cbtree\errors\
\Test01\spiderbasic\dojo\dgrid\
\Test01\spiderbasic\dojo\dgrid\css\
\Test01\spiderbasic\dojo\nls\
\Test01\spiderbasic\themes\
\Test01\spiderbasic\themes\flat\
\Test01\index.html
\Test01\spiderbasic.js
\Test01\spiderbasic\canvas-toBlob.min.js
\Test01\spiderbasic\dojo\cbtree\errors\CBTErrors.json
\Test01\spiderbasic\dojo\dgrid\css\dgrid.css
\Test01\spiderbasic\dojo\dojo.js
\Test01\spiderbasic\dojo\nls\colors.js
\Test01\spiderbasic\dojo\nls\dojo_de.js
\Test01\spiderbasic\filesaver.min.js

\Test01\spiderbasic\paper-full.min.js
\Test01\spiderbasic\platform.js
\Test01\spiderbasic\put.min.js
\Test01\spiderbasic\themes\flat\close.png
\Test01\spiderbasic\themes\flat\window.css
\Test01\spiderbasic\xdate.min.js
\Test01\Test01.sb

Simple Test: double click on the index.html file. If it opens correct in the browser it should open also in the gadget.

the app loads without problems in the browser. The WebViewGadget() still remains empty.

I have added a global error handler to Index.html as a test.

Code: Select all

<script type="text/javascript">
window.onerror = function(msg, url, line, col, error) {
   alert("Error: " + msg);
};
</script>

When I start my program I get the following message:

Error: Uncaught ReferenceError: dojoConfig is not defined

and afterwards:

Error: Uncaught ReferenceError: spiderCheckBrowser is not defined

The WebView runtime is up to date:

Hm ...

Code: Select all

function spiderCheckBrowser()

is inside:

\Test01\spiderbasic\init.js

Also

Code: Select all

var dojoConfig = { ...

In my index.html it is included:

Code: Select all

<script type="text/javascript" src="spiderbasic/init.js"></script>

Very strange!

This is the HTML file that I load into the WebViewGadget:

Code: Select all

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<meta name="viewport" content="user-scalable=no, width=device-width, height=device-height, initial-scale=1, minimum-scale=1, maximum-scale=1, shrink-to-fit=no">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<script type="text/javascript">var spider = {}; spider.nbModules = 1; spider.nbLoadedModules = 0;</script>

<title>HelloWorld</title>

<script type="text/javascript">function onLoad() { spiderCheckBrowser(); }</script>
<script type="text/javascript" src="spiderbasic/platform.js"></script>
<script type="text/javascript" src="spiderbasic/init.js"></script>
<script type="text/javascript">dojoConfig.baseUrl = 'spiderbasic/'; </script>
<script type="text/javascript" src="spiderbasic/dojo/dojo.js"></script>
<script type="text/javascript" src="spiderbasic/main.js"></script>
<script type="text/javascript" src="spiderbasic/debug.js"></script>
<link rel="stylesheet" href="spiderbasic/dojo/themes/flat/flat.css" />
<link rel="stylesheet" href="spiderbasic/dojo/dgrid/css/dgrid.css" />
<script type="text/javascript" src="spiderbasic/xdate.min.js"></script>
<link rel="stylesheet" title="Default" href="spiderbasic/themes/flat/window.css" type="text/css"/>
<script type="text/javascript" src="spiderbasic.js?t=1703626203"></script>

</head>

<body oncontextmenu="return false;" class="flat" id="spiderbody" onload="onLoad()">

</body>
</html>

If I then right-click on the WebView gadget and select "Save as...", it will be saved here:

Code: Select all

<!DOCTYPE html>
<!-- saved from url=(0011)about:blank -->
<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<meta name="viewport" content="user-scalable=no, width=device-width, height=device-height, initial-scale=1, minimum-scale=1, maximum-scale=1, shrink-to-fit=no">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<script type="text/javascript">var spider = {}; spider.nbModules = 1; spider.nbLoadedModules = 0;</script>

<title>HelloWorld</title>

<script type="text/javascript">function onLoad() { spiderCheckBrowser(); }</script>
<script type="text/javascript" src=""></script>
<script type="text/javascript" src=""></script>
<script type="text/javascript">dojoConfig.baseUrl = 'spiderbasic/'; </script>
<script type="text/javascript" src=""></script>
<script type="text/javascript" src=""></script>
<script type="text/javascript" src=""></script>
<link rel="stylesheet" href="">
<link rel="stylesheet" href="">
<script type="text/javascript" src=""></script>
<link rel="stylesheet" title="Default" href="" type="text/css">
<script type="text/javascript" src=""></script>

</head>

<body oncontextmenu="return false;" class="flat" id="spiderbody" onload="onLoad()">

</body></html>

All src attributes are empty. Why?

I think you will need to specify a path to have it working, I will add this for the next beta.

Posted: **Wed Dec 27, 2023 11:49 am**

Do you have a developer console inside the new webview or similar? This way you could check for CSP errors or similar.

Posted: **Wed Dec 27, 2023 12:05 pm**

No, I do not have access to the DEV console in the WebViewGadget.

Works perfectly now

Thanks @Fred!

Code: Select all

OpenWindow   (0,  0,  0, 1000, 800,"", #PB_Window_SystemMenu | #PB_Window_ScreenCentered) 
WebViewGadget(0, 10, 10,  980, 780)
SetGadgetText(0, "file://c:/temp/helloworld/index.html")
Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow

I've read it somewhere before, but unfortunately I've forgotten it

... what's the difference between the two gadgets again?

Code: Select all

OpenWindow   (0,  0,  0, 1600, 800,"", #PB_Window_SystemMenu | #PB_Window_ScreenCentered) 
WebViewGadget(0, 10, 10,  700, 780)
WebGadget    (1, 710, 10,  700, 780, "", #PB_Web_Edge)
SetGadgetText(0, "https://www.whatsmybrowser.org")
SetGadgetText(1, "https://www.whatsmybrowser.org")
Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow
