PB.Ex WebGadget 1.1.0.0 has been released.

Changelog:

Added: SetWebGadgetExProxy()

@zikitrake
You now have the SetWebGadgetExProxy function. I tested with 108.61.86.187:8080 (https-Proxy).

Thank you

It works like a charm

Mr. Applicant, with a new request

Would it be possible to reassign a new proxy to an existing WebGadgetEx, when one has already been assigned previously?

Again, thank you for this lib

Edited and added

What is wrong in this code?

Start a WebGadgetEx with a proxy.
I release the Gadget and close the library.
I open the library again and assign a new proxy before creating a new gadget.

But it continues to maintain the first proxy I assigned in step 1.

Hi, Incredible work !

These offers many new way to use Purebasic with HTML GUI.

Is there a way to store DLLs and CEF package outside of the app folder?

Regards !

Posted: **Mon Sep 23, 2019 10:01 am**

Hi RSBasic,

Is it normal that SetWebGadgetExText() always returns 1, even if the internet connection is interrupted?

@fouines

Is there a way to store DLLs and CEF package outside of the app folder?

It seems also not be possible with electron famework.

But, You can put all those things included (IncludeBinary) in Your source and write it out at runtime.
Did that for other things and it worked seemless.

Seems like a lot of work, but the result is a clean, simple (even bigger) executable.

Hello!
The ExecuteWebGadgetExJavaScript function does not return the result to javascript if it is carried out from a flow.

Whether it is possible as that to correct?

Also from a flow the WebGadgetEx function does not work.

And how still it is possible to receive cookie with webgadget with HttpOnly flag?
Javascript does not take cookie with HttpOnly flag.

If I want to use the latest CEF available, how to proceed? Is it OK to just download the latest CEF and drop it over the existing one, or are there more steps (rebuilding some files, etc) in the process?

Posted: **Fri Dec 27, 2019 4:59 pm**

Great module!

But it's using an old version of Chromium. Is there a newer version available?
And is the source for the PureBasic DLL available?

Hi Ray,

I just discovered your PB.Ex_WebGadget ... WOW, that's brilliant ... how could I have missed it for so long?

Ok ... I wasn't active for wayyyy to long.

As a PBler who struggled a lot with the genuine WebGadget, this looks very promising.

Will there be any chance, you could implement some of the following functionalities into PB.Ex_WebGadget?

To handle Events:
- BindWebEvent() - to receive and process Events, received by WegBadgetEx() (like Events on incoming Push-Data)

To communicate with Page-Elements:
- ExamineElements() - to examine the Elements included in the actual WebPage (like text- & string-fields, Buttons, etc.)
- GetElementProperties() - to get Info about the actual examined Element (like Name, Type (Text/String/Button/Image/etc.), Value (e.g. Text, URL), ...)
- SetElementProperties() - to set Values of an Element (like Value (e.g. Text of a String-Element), or clicking a Button, ...)

To work with plane Page-Text:
- SetWebGadgetExState() - with State = #PBEx_Web_SelectAll, to select the whole Text.
- GetWebGadgetExItemText() - with Entry = #PB_Web_SelectedText
(Or even better, add Entry = #PBEx_Web_AllText, to get the full Text, without the need of selecting the whole Text first.

This could make the communication with Web-Content sooooooo much easier !!!

As an example what I'm doing so far using the genuine WebGadget:
E.g. on THIS or THIS site, the Stock-Values are changing all the time during stock-hours (by JS and pushed data?), but the HTML-Code does not change - so I cannot process the HTML-code to get actual Values.
So far I send a mouseclick to the Webgadget to activate it (just ActivateGadget() does not work), then I send a "Select-All" Keyboard-Event (Ctrl-A) to the WebGadget to select all the text and then I use #PB-Web_SelectedText to get and process the Text.
Further, because I did not get a clear Event when the WebGadget() has received pushed Data and changed Values, I have to get and process the text way to often, or even loose some changed Data.

Would be great if some of these functionalities could be included in WebGadgetEx().

But anyway ... thanks a lot for this great WebGadget-Replacement !!!

Happy Greetings 'aus der Eifel',
PureLust.
