Mark,

I've apparently found myself with "a case of the Mondays".  So sorry for my
mood.  Carry on with being awesome.  You and the team really are quite
awesome!  I mean it.

Um - where did I say the request was going to be implemented NOW? 
Nowhere that I can see...


I filed an enhancement request so the suggestion wasn't lost - why did 
I?


Because I recalled adding an opaque property to the mobileControl 
"browser" API years ago that did what was requested (on both iOS and 
Android, IIRC). Given that Mac now uses WebView and not CEF, and thus 
benefits from the flexibility of NSViews directly, it seemed reasonable 
that the same approach used then would work on Mac too.


Therefore, it seemed a reasonable thing to record this fact - it gives 
no indication of when it might get done, if at all (of course, being 
open-source means that someone who is not us might do it).


Warmest Regards,

Mark.

Re-implementing audio and video in Linux is not currently on our near

todo list.

Thank you for this, Mark.

I realize how many improvement requests the LC staff has to handle, so I do 
understand why we cannot all have our way whenever we make a request.

These nuances will no doubt be useful on those platforms - thanks.

Any chance we'll see the ability to play audio and video at all in Linux 
restored?

Hi Mark,

Would you guys consider looking into this further? It would give developers so 
many presentation options.

Would it be easy for the LC team to implement a transparent mode for
browser widgets, where the background color is transparent, allowing
other objects to show through?

This would obviate the need for some the processor intensive image
transfers in and out of the widget.

I know one would have to set the background-color of the body element
to transparent and set a couple of settings in the WebView calls. Is
that all it would take?


The browser widget uses a system 'view' (UIView on Mac, View on Android,
HWND on Windows, NSView on Mac and X11 Window on Linux) to host the 
browser

control - thus whether or not they can be composited with a transparent
background depends on the system.

For Mac, Android and iOS it is probably possible by just toggling a flag
to say whether the view is opaque or not (although I've not looked into
it).

For Windows, Linux things are more tricky - as it requires that child
windows composite into the parent window. The 'traditional' model on 
those
platforms is that child windows are islands-on-their-own. That being 
said,

CEF does have a windowless mode in more recent versions which might be
usable to get a similar effect. However, I'm not sure what would be 
involved

in providing that as a choice.

Warmest Regards,

Mark.

Re: Transparent browser widgets?

[Jonathan Lynch via use-livecode]

I used to have an occasional bug in 8.1.3 where the browser widget would get a 
transparent background.

I had to restart the ide when that happened.

So, I think it may be possible.

Re: Transparent browser widgets?

I'll bet that a transparent background for the browser widget is
impossible to have. This would require that webkit or Chromium
(or whatever LC uses for the browser widget) allow a transparent
background.

What will be probably possible is setting the blendLevel of the
widget (as a whole), see Mark's note here:
http://quality.livecode.com/show_bug.cgi?id=19667

I'd guess that it wouldn't be hard to implement, but much harder to 
implement in a way performant enough for anyone to want to use. :)


I believe the browser widget maintains its own buffer, blitted to 
screen.  This makes it fast, but prevents it from mixing its rendering 
with LC-native controls.


For mixed rendering it would need to render within the compositing 
process Mark Waddingham outlined here a while back in answer to Jacque's 
question about acceleratedRendering.  My guess would be that doing so as 
rapidly as a browser might conceivably update would be computationally 
expensive.


That's just a guess, though.  I'd be happy to be wrong. Integrated 
rendering of the browser widget would be nice.

Transparent browser widgets?

[Jonathan Lynch via use-livecode]

Apparently, both WebView (android) and uiwebview (iOS) have transparent modes.

Would it be easy for the LC team to implement a transparent mode for browser 
widgets, where the background color is transparent, allowing other objects to 
show through?

This would obviate the need for some the processor intensive image transfers in 
and out of the widget.

I know one would have to set the background-color of the body element to 
transparent and set a couple of settings in the WebView calls. Is that all it 
would take?
