widget Browser not opening URL with picture

Youks · Post by **Youks** » Mon Nov 26, 2018 8:30 pm

Hi All,

After some testing I am unable to open an URL containing a GIF or JPEG with the widget whereas it works properly when creating a mobile browser, any known issues ?
By the way is it possible to load a GIF or JPEG through the browser, rotate the picture and display it back through the browser?

Thx in advanve.

Best regards

Sometimes the browser widget can't load "https:"-addresses. Try as "http:" or try to set the userAgent of the widget.
Images in the browser can be rotated directly in the browser using CSS (do "..." in widget "browser").

Do we have a bug report on that? HTTPS adoption is growing rapidly.

Hi Hernann,
Thx surprisingly the "http" vs "https" did the trick but i think it should be fixed or mentioned.
Could you kindly provide a hint regarding the userAgent method?

Being a total noob in java , will anything like (do" transform....rotate...") do what expected or is it a little more complex?

Thanks a million !

Hi Youks,
please report the address of the image that didn't load by "https:" to
https://quality.livecode.com
so that they can look into it.
Or post the address here.
This is probably a situation when "ordinary" browsers open a security dialog...
(I checked just now that for example on Mac the widget sets the same userAgent as Safari, so that's not the reason.)

Rotate an image in the browser widget.

Code: Select all

on mouseUp
  set htmltext of widget "browser" to fld "HTML"
  put "var d=document.getElementById('youks1');" & \
        "d.setAttribute('style','" & \
        "-webkit-transform:rotate(90deg); transform:rotate(90deg);" & \
        "transform-origin:50% 50%;')" into js
  do js in widget "Browser"
end mouseUp

fld "HTML":
<html><head></head><body>
<div id='youks1'><img src='http://hyperhh.de/TEST/Buchenberg640x480.png' alt='Rock my soul'></div>
</body></html>

Thank you so much Hermann!

It's a great start to understand how this works! I have put that into place , the picture shows up but temporarily rotates after few mouseUp and regains initial state. Is that what it is supposed to do or a step is missing?

Regards

Disregard my last comment !!!

I set the URL in an openCard and use the button only for the rotation and it works great!!! Thank you so much !! You Rock !!

This should work also in one go. But it's better to separate the call for the htmltext.

You could also use "load url" on openCard, so users with a slow connection get more time.
And later on (when the image is no longer needed) use "unload url".
Then the image is loaded (fast) from cache every time you set the htmltext.

p.s. Did you already try to use widget imageWidget (see "Sample Stacks")?
It loads also remote sources and rotation is very easy. And you don't need javaScript for that.

Dear Hermann,

I couldn't make the imageWidget work on android. I have created a single card with the widget and the preloaded picture but when built the card is empty.

PS: tried LC9.01 & 9.0.2 RC1 and minimum built KitKat 4.4

Hello all,

If you use a https URL with the browser widget, you have to make sure you include the "SSL and Encryption" lib in the standalone. This is done in the "Inclusions" pane.

I will update the bug report.

Kind regards,
Panos

Hmm I just tested and I can successfully load the image (i.e. the https URL) in the browser widget, either with or without the "SSL and Encryption" library.

What does the browser widget display for you when the image does not load?

Kind regards,
Panos
