Re: .mp4 support in browser widget--Windows

[Paul Dupuis via use-livecode]

As customers once had to download and install Quicktime for Windows to 
use a wide variety of media in Revolution/Livecode Standalones under 
Windows (XP, 7, 8.x, 10, 11), when QT for Win became obsolete, we just 
switched to directing customers to download and install LAV Filters 
instead. They do this as a separate install, done by the end user. So 
far, this has not seemed to be an issue or inhibited adoption. It also 
does not run afoul of any licensing issues with embedding LAV Filters in 
a LC standalone.


Regardless, if you want media file parity with macOS on Windows in 
Livecode and do not want to wait for whatever dp version of LC 10 might 
have MMF in it, then you need to add a codec pack for DirectShow. There 
are other options for additional DirectShow codecs to LAV Filters. I 
can't recall any of them - just that we reviewed a bunch, most of which 
were commercial and required licensing. LAV Filters was reliable, 
functional, easy to install, and free. I'm not endorsing it for your 
application or anyone else's, just noting what worked for us.

I've seen many cases the other way around, FOSS projects like Ubuntu where some 
users can benefit from prioprietary packages like NVidia device drivers. Ubuntu

Re: .mp4 support in browser widget--Windows

[Paul Dupuis via use-livecode]

There ARE methods to compress and store a 3rd party library or 
application as a property in a Livecode standalone and have the 
standalone on start up check (if there is a file ... or if there is a 
folder ...) for the app's presence and if not present, install it by 
uncompressing and writing it as a bnfile to the install location.


I don't know whether there are any Livecode lessons on the web site on 
how to do this or not or whether someone else who has done this may have 
code or tips to share.


First, you may want to manually install LAV Filters and see if it has 
the codecs for the media formats you want.


Livecode 10, before release, is supposed to get updated to use the 
Windows Media Foundation (and it's wide range of current codec for 
various media formats). This change (DirectShow to MMF) is not in the 
current (dp8) version. So a media coded pack (like LAV Filters) for 
DirectShow is your only option under there is a version of LC 10 that 
supports MMF.


If you set the way back machine, if you wanted to do media on Windows 
under old versions of Livecode (aka Revolution), you had to install 
Quicktime for Windows.

Is this an obstacle for LiveCode as software, and dependent on the underlying 
hardware?

My understanding from past LC forum posts is, to allow the widget to play the 
videos a flag is turned on and the widget recompiled.

I’m happy to pay for the licensing myself if I got to 50K customers!

Browser Widget and Google Maps Api on Win 10

[Ralph DiMola via use-livecode]

When in the IDE and testing using the browser widget the line below does not
ever complete. The call back to "startMapInit" is never called.

This works on Win 10 desktop in Chrome and LC deployed Android app using the
same browser widget as in the IDE. I will test on iOS. 

 

The real question is how to see JavaScript errors in the Browser Widget?

Facebook in Browser Widget

[Ralph DiMola via use-livecode]

LC 9.6.11 pro

Win 10

 

When I open Facebook url "https://www.facebook.com/someAccount"; in the
browser widget in an Android app I briefly see the Facebook page and then
get the error net:ERR_UNKNOWN_URL_SCHEME. The Error url displayed is
"fc://profile..." this used to work.

This happens if the FB app is or is not installed. What I would like is if
the app is not installed then open in the browser widget or if FB is
installed then open in the FB app. I have not tested iOS yet.

Thanks in advance

Re: Browser widget in Windows has trouble playing videos in websites

[Peter Bogdanoff via use-livecode]

Tom,

I’m finding the issue is more complex, and I’m still trying to get to the 
bottom of it.

Daily Motion, Vimeo, and YouTube pages all work on the Mac LC browser plugin.

Daily Motion, Vimeo, and some YouTube pages don’t in Windows. However, most of 
the gazillion YouTube videos work very well, just not all of the ones we made 
for our channel. Most of our videos were compressed on a Mac, but for all but a 
couple YouTube shows an error in the video window: 

"Your browser can’t play this video. Learn more."

'Learn more' shows a page that only says the browser is compatible.


We made two on a Windows machine, one works, but the other doesn’t—both using 
the work flow, same compressor/wrapper ( I don’t know which).

I’ve tried recompressing on the Mac a sample video using everything available, 
including Ogg. None work in Windows from our YouTube channel.

I’m going to retry compressing within a Windows app. See if it makes a 
difference. 

It seems to me the issue is more than lack of support for h264.

Peter

Re: Browser widget in Windows has trouble playing videos in websites

[Tom Glod via use-livecode]

Hey Peter, this surely has to do with videos that are compressed using
h264. that build of CEF does not support this codec.
I am not sure if the updated browser in the upcoming windows version will
support h264.
I am surprised to find out that the apple version of the browser has
support for h264, i assumed the problem was cross platform.
On youtube LIVE videos are h264, and videos that have been on the site a
while get a different codec.

Browser widget in Windows has trouble playing videos in websites

[Peter Bogdanoff via use-livecode]

I submitted Bug 24479 today with a sample stack.

Youtube, Vimeo, Daily Motion all have unreliable playing of their videos in LC 
browser widget in Windows 10, LC 10.0.0 dp7, both in the IDE and standalone.

Vimeo and Daily Motion won’t play videos on their sites. They show an error 
message in the video player.

YouTube does play, but there are some videos in my channel, and others here and 
there that show a YouTube error when loading.

No problem with the Mac browser widget.

Browser widget error

[Peter Bogdanoff via use-livecode]

Hi,

I’m getting an error from the browser widget. I only see it when I’m running in 
Sonoma on an M2 Mac mini. All earlier Macs (Ventura and earlier) don’t trigger 
it. This is part of a routine that sets JS handlers to control the playing of a 
YouTube movie in the browser.

I created a small sample stack to file a bug report, but actually got that one 
to work with no errors. The source stack is still showing errors, and I can’t 
seem yet to track down what’s causing it. The calls still function, but pop up 
the error box.

The errorDialog message shows this. I guess that some explanation of 
specifically what the error is in "error evaluating javascript” would be 
helpful:
863,0,0,runtime

864,0,0,error evaluating javascript

865,0,0,browser.lcb

866,0,0,1007

897,0,0,1

865,0,0,browser.lcb

866,0,0,999

897,0,0,1

This is in LC 10.0.0-dp-6, the version of LC that seems to function best with 
this Sonoma M2 Mac. I have found that this computer is so fast, errors appear 
such that I had  to do some adjusting of the timing of events.

I'm guessing you are using 10-dp-5 :)

The issues here are regressions caused by the switch to WKWebView in 10 
(previously we used the older WebView system web browser API):


The missing progressChanged messages issue is 
https://quality.livecode.com/show_bug.cgi?id=24271


The missing other messages issue is 
https://quality.livecode.com/show_bug.cgi?id=24247


The latter is related to server vs local redirects in the web page.

Both should be fixed in the upcoming 10-dp-6.

Browser widget: "Navigation request cancelled"

[Ben Rubinstein via use-livecode]

Trying to use the browser widget to access an internal site, I'm having a lot 
of trouble.


If I send it (by setting the URL property of the widget) to the root of the 
hostname, it loads the page succesfully, although the widget gets a 
browserDocumentLoadFailed message "navigation request cancelled".


If I set the URL property to some pages within the site, they load succesfully 
without that message.


If I set the URL property to some other pages, they do not load, and that 
message is received.


It's completely consistent which URLs work, and which don't.

If I send the widget to a URL which works, I can navigate anywhere within the 
site without problems, including to the URLs which don't work using set.


I haven't managed to pin down what distinguishes the working URLs from 
non-working. All the non-working ones I've found involve query parameters; but 
some of the working ones do also.


My question is: how can I debug this issue? Are there any ways to get insight 
into the loading process?


I am catching and reporting these messages:
browserDocumentLoadFailed
browserDocumentLoadComplete
browserNavigateFailed
browserNavigateComplete
browserUnhandledLoadRequest

... but the only ones that trigger are either browserDocumentLoadFailed or 
browserUnhandledLoadRequest, or browserDocumentLoadComplete - always with the 
parameter being the requested URL. I'm guessing, though I might be wrong, that 
the issue is actually with one of the elements being requested by the 
document, but this is never in the parameter.


Additionally, browserProgressChanged never seems to be sent.

Is it possible to get any more detail about what's going on?

TIA,

Ben

Browser widget "Navigation request cancelled"/"NSURLErrorDomain error -999"

[Ben Rubinstein via use-livecode]

I'm finding intermittent issues with the browser widget failing to load an 
internal site.


In 9.6.8, the error (in browserDocumentLoadFailed) will usually be 
"NSURLErrorDomain error -999". In 10.0.0 (dp 5) it will be "Navigation request 
cancelled".


Alternatively, sometimes  (at least in 9.6.8) it will be
	"The resource could not be loaded because the App Transport Security policy 
requires the use of a secure connection."


... which is fair enough, because it's an "http:" URL rather than an "https:" 
(this is an application on our intranet); but the whacky part is that 
_sometimes_ I can load the site, and once loaded I can navigate it fine.


In particular I have more success in loading it in 10.0.0 (dp 5) - although 
sometimes the site will load, _and_ the browserDocumentLoadFailed message will 
be sent! I also sometimes find I can load it if I set the URL in the property 
inspector for the browser widget, where setting it in script fails.


Can anyone shed light? I'd prefer to get this working in 9.6.8, because due to 
https://quality.livecode.com/show_bug.cgi?id=24268 I tend to lose work in 
10.0.0 (dp 5) - but if I could get it consistently working in either that 
would be a step forward!

Ben

The web browser widget is implemented as an IFrame - this comes with it 
a fair amount of security restrictions unless the website being embedded 
has appropriate cross-origin settings (or comes from the same host as

In this case, I suspect the website is just refusing to be embedded -

Re: "get in widget"?? How can I get a value out of a browser widget into LiveCode?

[Ben Rubinstein via use-livecode]

I've found a solution. For the benefit of others (and myself, because I'll 
have forgotten this next time I want it), this can be done using "the 
javascriptHandlers".


So you can set up a handler to be called from the browser:
set the javascriptHandlers of widget "Browser" to "myJSHandler"

... and then have javascript pass the expression to that handler:

do "liveCode.myJSHandler(document.title);" in widget "browser"

or
 do "document.title" in widget "browser"; put the result

just put empty.

Any other ideas? I don't know whether I need to do something different in the

I have now discovered that this probably was related to MacOS 13.0. Having 
upgraded the OS to 13.2.1 solved the problem on the affected machine.

Bug in browser widget?

[Tore Nilsen via use-livecode]

I have come across a bug in the browser widget. The browser will not show any 
video when the video is embedded into the web page. The poster image and the 
thumbnail images will display properly, but once the videoplayer is started the 
screen goes blank. The player will indeed play and the sound from the video can 
be heard! Videos that are displayed using the video-tag in the html file seems 
to work OK.

Are there anyone else who has the same experience? I am on MacOS 13.0 and LC 10

Re: Browser Widget navigation and urls

[Ben Rubinstein via use-livecode]

The website might be actually a JavaScript 'app' that's displaying different 
information rather than navigating to different pages, which is now a very 
popular web dev technique.


A responsible implementation of this approach includes a non-JS fallback, for 
accessibility purposes; and makes the app manipulate the browser's URL display 
so that if someone bookmarks the page, or sends a link, the link will work to 
display the same 'page' as the user intended.


You might be able to inject something to access the 'window.location' object, 
which I think is what is manipulated in this case.

changes as I navigate the pages, while if I navigate to the saem place in
the same way in Livecodes embedded browser "the url" of the browser widget

Re: Equivalent of a field's "on linkclicked" message in a browser widget?

[Klaus major-k via use-livecode]

Hi all,

with some help form the LC forum, I finally had kind of success with this:

on browserNavigateBegin pUrl
   lock screen
   if pURL ends with ".pdf" then
 libURLDownloadToFile pUrl, (specialfolderpath("desktop") & "/test666.pdf")
 go back in widget 1
   end if
  unlock screen
end browserNavigateBegin
-
With the line GO BACK IN WIDGET 1 the clicked url will NOT get displayed!
Seems the only way to (fake) CANCEL the navigation.

I guess it hasn't been fixed yet, or else we don't understand how to use 
it. When I was trying it, breakpoints didn't even trigger so I assumed the 
messages weren't being sent. Did you put the handlers in the widget script? 
When I tested we didn't have widgets yet.


If that doesn't work I'm not sure what will. Maybe you'd need some javascript?

Thanks for any hint!
I want to check if the user clicked e.g. a PDF file and download the file 
in that case.

What message do I have to catch in the browser widget?
You could try "browserDocumentLoadBegin" or "browserNavigateBegin" which 
would give you the URL that was clicked. But most browsers now download or 
display the PDF automatically when a PDF link is clicked. Firefox opens the 
PDF in a new window, and I think Safari downloads it. Not sure about Windows.

Windows, too, if the Acrobat Plug-in is installed on the target machine.
Only Android cannot display in a browser so far, too bad.
If this is for mobile, the URL might be enough information. BTW, I tried to 
use these messages a very long time ago and they were not sent, but 
hopefully that's been fixed by now.

Fingers crossed, will try and tell. :-)

Thanks for any hint!


I want to check if the user clicked e.g. a PDF file and download the file in 
that case.
What message do I have to catch in the browser widget?


You could try "browserDocumentLoadBegin" or "browserNavigateBegin" which would give you the URL 
that was clicked. But most browsers now download or display the PDF automatically when a PDF 
link is clicked. Firefox opens the PDF in a new window, and I think Safari downloads it. Not 
sure about Windows.


If this is for mobile, the URL might be enough information. BTW, I tried to use these messages 
a very long time ago and they were not sent, but hopefully that's been fixed by now.

Re: Browser widget doesn't display PDF

[matthias rebbe via use-livecode]

Hello Panos,

thanks for reminding me of bug 22534. 
I should have remember it. That bug report is based on a support request i 
filed. ;)

Thanks, i was not aware of that report. Btw. you are commenting in that report, 
that you could replicate the problem with a 316 page PDF, but not with a 5 page 
pdf.
In my case the PDF has only 1 page.

I knew that one already, because its a bug report based on a support request i 
filed. ;) 
To be honest, i almost forget about it. 
Rereading my comments i remembered that one hast remove the plugins and logoff 
and login again to get it working with the widget.

Btw. this might be a workaround for me if i need also the Acrobat plugins, but 
according to the dictionary the PDF widget is only available with a Pro license.
So this is not a workaround for everyone.


Anyway, thanks again.

Matthias

Browser widget doesn't display PDF

[matthias rebbe via use-livecode]

Hello,

i am currently having problems that a browser widget doesn't display a pdf, 
regardless if remote or local.

I just see a white blank page. Sometime an error message comes up telling me 
that "PDFViewer could not find a compatible version of Adobe Acrobat or Adobe 
Reader for displaying this PDF file."
Something like that. I get a German error message.

The interesting part is, that Safari does not have a problem with displaying 
the PDF and the folders ~/library/internet-plugins and 
/library/Internet-plugins both contain the Acrobat plugins.

Tried here with LC 9.6.9RC2 and 10DP4 on Ventura 13.0.1.

Does anyone has an idea what might be wrong?

Regards,
Matthias

Re: Browser Widget and Images

[Rick Harrison via use-livecode]

Thanks!

I had forgotten about "import as control" and about
set the imagedata of image “my image”.

set the imagedata doesn’t fit to the image’s object size though.
I would probably have to resize the image beforehand.

I also came across:

put URL "binfile:///ExportedImageFile.png" into image  “my image”

The above does fit the image size nicely and I can paint on it etc.

Thanks for all of your help!

what Jim said! :-)

Thisw way the image becomes part of the stack as if "imported as control" 
and you can paint on it or whatever, which is not possible with referenced 
images, be they local or online.

Rick,
set the imagedata of img "myImage" to the imagedata of img "myImage"

Will replace the referenced image with the actual content of that image.
In other words the image will now be local and you can then manipulate its data.
No need for snapshots. Although they work too!

Re: Browser Widget and Images

[Rick Harrison via use-livecode]

Hi Klaus,

Thanks for answering.

So accessing the URL of the image directly in the image object
puts the image there, which is a good first step.

How is it stored however?  

If one looks at the image source it still shows the URL. 
 
I find I’m unable to paint on top of the image, probably 
because that would require my being able to modify the
online URL which isn’t possible for the obvious reason.

I probably need to make a local copy of the image to
be able to work on it.  Export image? Copy it to
the clipboard and paste it elsewhere?

Suggestions?

Rick

why not just set the FILENAME of the image object to the file, either local or

If the image is very big, you could group that single image object and add the 
groups scrollbars.
Or just scale the image...

Browser Widget and Images

[Rick Harrison via use-livecode]

I have a large free public domain image displaying nicely in my LC Browser 
Widget.

I want to bring the image directly into a LiveCode image object to be able to 
play around with it.

What’s the best way to do that?

While I was looking around in the dictionary for possibilities, I came
across some older revBrowser commands.  Do they work with with
the new browser widget or are the two completely different animals?

Thanks,

Rick

Re: Browser Widget Issues

[Tom Glod via use-livecode]

Hi Rick,

document.getElementById("Butto Name").click();

that should work ...but yes this solution assumes you know the name of the
button.

I can't say for sure but I think its that LC is looking for "what
livecode control" is under this clickloc . and then sends a message
to that controlso in this case, it just send mouseUp to the widget. If
the widget even accepts it.

Good luck Rick.

Re: Browser Widget Issues

[Rick Harrison via use-livecode]

Hi Tom,

Do you have a more specific Javascript/LC example?

I’m not a big fan of Javascript and only use it very sparingly.

I would also have to first scan the HTML to find the name of the button I want 
it to activate wouldn’t I?

If I have to go into that fine detail I would be better off scanning for the 
link and just using a URL statement.

Why doesn’t click at location work?

Thanks,

Rick

You just need to pass some javascript to the browser to trigger the button
you want.

do this_js in widget "myBrowser"

and this_js should have the javascript to click the button.

Imagine the possibilities :)

Browser Widget Issues

[Rick Harrison via use-livecode]

I was hoping to be able to programmatically
tell the browser widget where to go to next
by having LC click on an image or button
within the browser window.  

So far I have had no success with that.  
Is there a bug in LC preventing me from
doing this seemingly simple task?

Is there a work around?

Thanks in advance!

Re: Browser widget - follow redirects setting?

[Keith Clarke via use-livecode]

Hi Matthias,
Thanks for your response and experiment.

Unfortunately, I get the same experience with 'launch URL in...' and 'set the 
URL of…’ widget “Browser”

I think it might be my URL. I’m trying to access the Salesforce OAuth 2.0 User 
Agent flow via the browser, as I can’t get the OAuth library to work for this 
flow.

Maybe I’ll try dipping my to into tsnet, as that looks like it may have the 
comparative mechanisms to replicate a recipe I have working from PHP.

Thanks and regards,
Keith

Re: Browser widget - follow redirects setting?

[matthias rebbe via use-livecode]

Keith,

what happens, if you set the URL of the browser widget to tURL?

I tried here both "set the url..." and also "launch URL ... in widget.." with 
an online Shop. I tried to launch the account page. In both cases i was 
redirected to the login page.
The only thing i noticed is, that the URL of the widget kept to be the URL of 
the account page although  the login page was opened/displayed.

Regards,
Matthias

Browser widget - follow redirects setting?

[Keith Clarke via use-livecode]

Hi folks,
Is there any hidden / undocumented setting for the Browser widget that will 
allow it to follow redirects?

Using launch URL tURL opens the default browser on my machine and - if I’m not 
logged into the server - redirects to a login page, the address of which I can 
see in the browser’s address bar.

However, launch URL tURL in widget "Browser” doesn’t redirect and subsequently 
put the URL of widget  “Browser" shows tURL unchanged.

Am I missing a trick?
Best,
Keith

I think you'll need to include an Edit menu with the normal shortcuts 
(Cut/Copy/Paste) - make sure the tag of the items is correct as the 
engine uses those to map them to the internal (Cocoa) references. e.g.


  (Cu&t /X|cut
  (&Copy /C|copy
  (&Paste /V|paste

Cocoa-based controls (which the browser widget uses the WebView variant 
of) don't respond to shortcuts directly, but only via menu item 
accelerators - so the browser widget needs the menu items present for 
such shortcuts to work.


Warmest Regards,

Mark.

How to paste into a form element in the browser widget

I have a problem pasting into a form element on a web page in the browser 
widget. This works well in the IDE, but not in a standalone application. The 
application has no menus, but I have included a pasteKey script to handle paste 
shortcuts. This does not seem to do the trick in the browser widget. I have

Re: access DOM in browser widget?

[Tim Selander via use-livecode]

Sorry to pick up this thread half a year later, but I am 
searching for an answer to a related problem.


On the LiveCode Forums I learned that if the page is loaded in a 
Browser widget on the desktop version of LC, you can [get the 
htmltext of widget "browser"] and get the info JS provides that 
is not part of the page's HTML source code. (In my case, I want 
the number of plays of a track on Soundcloud.)


But I would like to get at this JS/DOM info through an LC Server 
script running on my on-rev.com server -- no browser widget there.


Does anyone know how to get the JS/DOM generated text from a web 
page using LC Server?


Any help appreciated!

Thanks for responding Tom


But if yoiu need any more of a direct way accessing itI don't know of one.

Yes, that's what I'm after: to have a browser widget in a LiveCode stack, and 
be able to access the DOM (not the htmlText) in LiveCode script.

It's not my page so I can't add javascript to it.

Does anyone know if this is possible?

Re: How to deploy app from Mac to Linux (with Browser widget) ?

[panagiotis m via use-livecode]

Hello Ben,

Unfortunately the browser widget is still broken on most Linux distros. You
might be able to work this around in your app by using "launch url .." if
the platform is Linux, to use the default browser instead of the browser
widget.

Kind regards,
Panos

The browser widget has properties hScrollbar and vScrollbar - but doesn't

Is there any way to get and set the scroll (FWIW I'm only interested in the
vertical) of a browser widget?

How to deploy app from Mac to Linux (with Browser widget) ?

[Ben Rubinstein via use-livecode]

I've made a little utility that's been working for me on Mac (actually I've 
just been running it in the IDE). I wanted to share it with a colleague who 
uses Linux, so I selected Mac, Windows, Linux in the standalone settings, 
selected "auto-detect" for inclusions, built it.


Tested the standalone Mac app on my computer, works fine.

Zipped up the Linux64 package, sent my colleague the zip. She said "something 
froze and i cannot close it".


Two questions:

- do I need to do something special to package up the Linux app before sending 
it? Does my colleague need to do something special to install/run it? She's 
using "5.4.0-80-generic #90-Ubuntu".


- this uses the browser widget. I've seen something on the list about will we 
ever get CEF browser on Linux - but the widget was listed as for linux in the 
Standalone Builder,  and indeed a folder "CEF" is the bulk of the "Externals" 
folder that the Standalone Builder created. So I'm guessing that was an 
historical problem.


Please enlighten me!

TIA,

Ben

Re: How to scale the content of the Browser Widget

[Keith Clarke via use-livecode]

An idea extending Ralph's suggestion to use html, along with styling to do the 
heavy lifting rather than JavaScript. A div with a background image might do 
the trick...

Image title
 

...where:
... 'vh' is viewport height units (as percentage) and '2rem' leaves some space 
for the image title, (expressed as font size relative to that in the html root 
element).

...background provides for background images, and size as 'cover' fill the 
containing div (with some scaling in one dimension that affects aspect ratio) - 
so use 'contain' if you want the image to be as large as possible with its 
aspect ratio left intact. See help for this background shorthand styling 
examples and related information here

RE: How to scale the content of the Browser Widget

One way...
Create a local html template and replace an href place holder in the
template to the url of the web server image.
Then load the template page into the browser widget and let html do the
resizing heavy lifting. This will not break cors.

Subject: How to scale the content of the Browser Widget

Hi,

i need to display jpeg images in the browser widget. The images are stored
on a webserver and i  have no control about the size of the images. 
What i can say is that the images are larger than the browser widget area.
Is there a way to scale the images so they are fully visible in the browser
widget? 
I do not want to temporarily store them on hard disk, resize them and then
display.
I need something like an "on the fly" scaling.  
I am wondering if this might be possible with Javascript? Unfortunately i am
not very used Javascript.

Does anyone know if this is possible?

Regards,

Matthias

Thanks Keith - the issue is with the HTML5 that uses modern webrtc standards 
for video - either the javascript is excluding the type of embedded framework 
Livecode is no using on MacOS - or the framework doesn’t;t yet support those. 
Features - I’d like to check - but not sure what Livecode is using under the 
hood. Would be nice if it were in the dictionary entry.

Re: Browser Widget Issue

[Keith Clarke via use-livecode]

Hi David,
Pass on the framework, but regarding the page…

FWIW from the message box, I was able to set the url of widget ‘Browser’ to 
"https://obs.ninja” (apparently empty...) but then put the htmltext of widget 
“Browser” to see that there is indeed some content. 

So, it’s not scripting itself to hide and there’s some content & potential to 
investigate why it’s rendering as 'white on white'. However, only inline 
styling is available as AFAIK there’s no dev tools nor access to any downloaded 
css files, wherever resources might get cached by the LC browser widget…?

Good luck,
Keith

It's not my page so I can't add javascript to it.

Browser Widget

[Terence Heaford via use-livecode]

I believe the Browser Widget uses the native browser and in that case it uses 
the same code as Safari on MacOS?

I have been using CanvasJS to create some charts and have been rendering the 
result in the Browser Widget using Set the URL of …..

These charts have been created on the computer and not via the internet.

Generally they render well except for the animation of the chart.

In Safari it's as smooth as silk.

In the Browser Widget there is some slight stutter that does slightly affect 
the user experience.

Does anyone know why this stutter exists with the Browser Widget and not with 
Safari and is there a solution?


Thanks

Terry

Re: Will Browser widget ever work on Linux?

[Tom Glod via use-livecode]

Thanks for all the inputs gentlemen

I agree on the need for cross platform embedded browser support.

Will LC use another embedded browser for the mac?

So I guess there are more questions than answers here in terms of a 3
platform solution.

I have my first ssd sitting in the box, and once i install it i will try
not to take it for granted when judging the "performance" of my work.

Cheers,

Tom

Re: Will Browser widget ever work on Linux?

Mark:

Yep, it actually feels great to be a Windows-first LiveCoder. 
Ironically, things "just work." In fact I'm doing a Windows app right 
now, using - guess what - the Browser widget. Works a treat.


It's hard to overstate how important embedded Browser support is. Along 
with, of course, the field object, which can do much more than most 
people realize. (The cliques and promoters/repeaters in this LC 
community always breathlessly push certain resources, at the expense of 
awareness about others.) Like the field, embedded Browser is a way to 
deliver and display so many different kinds of content that it should be 
considered a foundational part of LC. Can't afford to let it slip.


And the Browser needs to work fairly seamlessly cross-platform, to a 
reasonable extent. That's why we're all here, right?


About Windows: Once upon a time I was a big Mac guy and Mac-first 
shareware author. I was all about Mac...until Apple made some dumb and 
hypocritical UI decisions, contradicting their own doctrine repeatedly 
and destructively. They took a crowbar to the beloved Mac OS and made it 
much less convenient and satisfying to use.


I never jumped ship onto the Linux rowboat. Nice to have that platform - 
and by all means it should be supported. I'm still an enthusiastic 
Mac-second developer, and I welcome Linux work on occasion, but I 
adopted Windows as my primary OS since their UI had some advantages. To 
this day I'm very happy to be firmly cross-platform and proudly 
Windows-first.


Now that I have an SSD, the LC script editor troubles are a thing of the 
past too. LC simply made the mistake of designing broadly-used software 
on high-end hardware, so it wasn't a great design, especially for the 
masses. (Strange because that's usually a beginner's mistake.) Remember 
how the newly open-source LC was going to open up the world of coding to 
the third-world masses? Nope, not gonna happen, not with that kind of 
disk usage! I always design on budget hardware, so that at least the 
middle class can use the end product too.


But now SSD has become the standard for new budget hardware, so very 
soon that will be moot - once again LC runs just fine with modern 
antivirus and Windows 10. (Talking about a real Windows computer - hi 
Richmond - and not a partition or virtualized system. Real PC, real Mac 
is the way to go.) So for users stuck on "the dark side" of Mac or Linux 
- the grass really is greener over here at the moment. Fingers crossed.
