Re: Free SVG icons

[Brian Milby via use-livecode]

I started a thread over on the forums with a stack that I'm working on:
http://forums.livecode.com/viewtopic.php?f=10&t=30411

It will let you view 80 icons on a card and page though a whole set.  Icons
are imported to the stack directly from a folder of SVG files.

Hope someone finds it useful.

Re: Local Image Paths in HTML for Browser Widget Fails

ok, nevermind, you can't overlay the browser widget I guess.  Is there a

Re: Local Image Paths in HTML for Browser Widget Fails

[Mike Bonner via use-livecode]

2 possible options I can see.. either have a 2nd browser widget with that
page in it, and enable/disable hide/show or just move it out of the
screenrect..  Though it sounds like all you're doing is putting an animated
gif that you want to show during page load.   Can't you just pop it into an
image object, and then overlay it however you like on top of the browser
widget. hide/show/enable/disable as needed?

Re: Notifying users of Web Delays in Browser Widget

If I think a url is taking too long, I just move on. Does the user really 
need a notification?

Notifying users of Web Delays in Browser Widget

[Sannyasin Brahmanathaswami via use-livecode]

Where

1) we cannot use TSNet to "listen" to the socket being used by the Browser 
widget

2) We cannot overlay a browser with any kind of control/dialog on mobile (or 
desktop)

3) the browser widget takes the whole card screen on mobile phone, except 
bottom nav bar which is native LC control 50px high

4) it doesn't help to load your own local page with a loader give because this 
is "supplanted" by the remote URL and the browser widget goes blank while 
waiting for the remote page to load

5) we want to inform the user after 5 seconds that this is taking a long time 
and perhaps they may like to abort.

has anyone here wrapped this use case already?

I can think of various scenarios. but I'm loath to mess with the screen too 
much as we already having issues on Android with the browser widget. if we can 
hide the browser widget on mobile and we *can* over lay a control then we can 
load a native LC image with our loader animated GIF.. the it's a no-brainer to 
use this algorithm

check browserDocumentLoadComplete
on send in time every 500 milliseconds
if elapsed time > 5 seconds then
inform user, offer choices… if complete then hide our image and show the 
browser widget.

I am already doing the above and raising a small "snackbar" at the bottom of 
the screen that says "loading"…  that is <50 px high and since that area is not 
occupied by the browser widget, this works… but I would rather have a more "in 
your face" dialog for the user who is, say in mangroves of Bengal with 
Android/3G and is waiting, waiting and waiting for a page to load from some 
Cloud Flare server in Chennai, Delhi or Bangkok… (no kidding I actually have 
some users in that context)  my beta tester in Kerala wants some better 
notification for this situation.

But before I go down this road, I'm wondering what anyone else may have come to 
for a UI/UX for this that works we on both iOS and Android.

or boil down to a single question: Anyone having issues with hiding/showing the 
browser widget on Android? and using that space for native controls while it's 
hidden?

BR

OT: Throttling bandwidth on test devices seems to be a common requirement, if 
you are stuck with highspeed WIFI.. what to do?  A quick search, yes, lots of 
hits, but no  easy options… for either iOS or Android. Have you found one? For 
now I'm just switching to airplane mode, commenting out our 
"pingForConnection/Abort" handlers in test builds… but this is a nuisance…

@ Mike… thanks…

the htmltext # with
the url

this is all static content so all that was needed was, 

assets
   /info
  web-loading.html



 

and then this

command setWebURL
   put path_Assets() & "info/web-loading.html" into tLocalPath
   set the uirl of widget "body"  to tLocalPath 
end setWebURL


"of course"

@ HH, thanks for the base64 method… I can use that in other instances.

@ All, this really doesn’t get me what I want though, because as soon as we set 
the URL of the browser widget to the intended remote web page, our local page 
is of course "disconnected" the loader image is gone and the user is *still*

I must have been working too late and didn't see either of these to things, 
which, are of course obvious.  I'll start another thread on loading web

It works if you receive the list in email, only the nabble archives do that 
(and maybe some others.) The last person to post is assigned to all posts 
in the archive. It can change minute to minute.


Also, when replying to the list from an email client you may need to adjust 
your reply settings, otherwise the reply goes only to the poster and not to 
the entire list.

Second, layer order is preserved pretty well in LC. When you set the layer
of the group to top, as Kluas suggests, and then ungroup, all the child

What if you set the layer of the group to top before ungrouping?
set the layer of grp "playerGroup" to top

ungroup grp "playerGroup"

But, why do you need to ungroup?

Object layers

[Pyyhtiä Christer via use-livecode]

When setting object layers, how do they work actually?

The documentation states the higher the number of an object, the control is 
higher than the the object it is on.

This means that in case of two objects on top of each other a mouseClick would 
go first to the object with the higher layer number, yes?

And, it seems to be that not any two objects on a card can exist with the same 
layer number, if the objects are not in the same group, right?

Now if you have objects grouped, and you ungroup them, how to keep them still 
above any other layers they are on?  For example, you have a set of game 
buttons on the board, which you initially group to move them together, and then 
you need to ungroup them, and with sequential clocks you want to make sure the 
control is with a single button instead of first hitting the playboard squares, 
how do you make sure the buttons reside on top of the board.

I have experienced that ungrouping may send the individual objects to random 
layers.

thanks for testing!

I think I found the culprit:
In the Datagrid Library in the handler -> setprop dgColumnLabel [pColumn] pValue
Line 6094:
...
if the platform is "macos" then put "mac" into theColsA[pColumn]["encoding"]
...

If I change "mac" to "utf8", the header look fine in the simulator!
Did not test the windows encoding, but should surely also read "utf8"

Will file a but report later today.

settheangleofwidget "hour" toINC

but it didn't maintain its aspect ratio . . .
