I have no idea from what you are talking.
I created a WebView2 Gadget as a replacement for the outdated WebGadget().
Inside you can open web pages, but not browsers.

From the recent activity above
I am thinking that I may need to re-download "Webview2 control - Chromium browser for Purebasic (Windows)"
to keep up-to-date .
Thanks

To run my WebView2Gadget()

You need the original stuff from justin:
https://github.com/omegakode/PBWebview2

You need to add the extensions to webvie2.pbi
And if the original loader creates a warning about unresolved externals, you need also the version which I provided as first listing.
Then place the WebView2gadget.pbi in same folder and copy the required loader dll (x86 or x64) in the same directory.

After this the demo inside WebView2Gadget.pbi should work.

Many work, but I don't want to steal the work of justin, since my work is only an addition to his work.

If the WebView2 runtime is not installed you need also to install it from here:
https://go.microsoft.com/fwlink/p/?LinkId=2124703

But on many Win10 PCs it is already available and on Win11 it is definately installed.

Is there a native solution?

Hmm? Sorry I think I misunderstood the comment of Fred; thought the Web Gadget of PB was going to become a Chromium control, "natively". It's a bit cringy to still read in 2022: "The WebGadget uses the Internet Explorer 4.0+ ActiveX object on Windows. ".

not accurate
WebGadget uses ie and can be configured up to the latest ie11 emulation (i.e full IE11) by setting properly registry

Code: Select all

Procedure SetBrowserFeatureControl(rpath.s, dwValue.i)
  dwLabel.s     = GetFilePart(ProgramFilename())   
  RegCreateKeyEx_(#HKEY_CURRENT_USER, "SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\"+ rPath.s, 0, #Null, #REG_OPTION_VOLATILE, #KEY_ALL_ACCESS, #Null, @phkResult, @Disposition)
  RegSetValueEx_(phkResult, @dwLabel, 0, #REG_DWORD, @dwValue, SizeOf(Long))  
EndProcedure

SetBrowserFeatureControl("FEATURE_BROWSER_EMULATION", 11001)   ;; enable IE11 rendering

even when WebGadget2() becomes native using native webview2 by microsoft (chromium/edge)
WebGadget() WILL and SHOULD remain, because of very high dependency of active components in a numerous commercial products out there need this

offcourse all new design should focus in html5 but compatibility should be needed for decades...

For example, you could use something like this

Code: Select all

UseWebGadget([WebView2LoaderLibraryName$])

similar to UseSQLiteDatabase() or

Code: Select all

InitWebGadget([WebView2LoaderLibraryName$])

similar to InitScintilla()

Wow!

I don't know about it, thanks for sharing

First I want to thank Justin and infratec for the great work !

@infratec: there seem to be a strange bug in the WebView2 gadget replacement.
Calling WebView2SetGadgetText results in an IMA

To reproduce, please modify the sample code

Code: Select all

  OpenWindow(0, 0, 0, 1230, 820, "WebView2 Gadget", #PB_Window_ScreenCentered|#PB_Window_MinimizeGadget|#PB_Window_SizeGadget)
  WebView2Gadget(1, 10, 10, 600, 800, "https://www.purebasic.fr/english")
  WebView2Gadget(2, 620, 10, 600, 800, "https://www.purebasic.fr/german")
  
  WebView2SetGadgetText(1,"https://www.purebasic.fr/english"); <--- adding this line leads to an IMA

IMA occurs in

Code: Select all

Procedure WebView2SetgadgetText(Gadget.i, URL$)
[..]
    *Gadget\wvCore\Navigate(URL$) ; <------ here the IMA occurs
[..]
EndProcedure

Do you have any idea ? Tested with X86 code

The problem is ... you are to fast.

The WebView2 from MS takes a bit time to load and initialize.
This is done in a thread.

You can see this, because the error comes before you can see:

Debug "Webview2Controller_Created"

I can implement a flag which is set when everything is finished.
But then you still have to wait for that flag.

Or I secure it, but then your command is not executed and I return a #False.

I test now how long it blocks if I wait until the WebView2Gadget() is completely working.

Posted: **Wed Jan 11, 2023 2:25 pm**

I can only fix it if I add this add the end of the WebView2Gadget():

Code: Select all

Repeat
  WindowEvent()
  Delay(10)
Until WebView2GadgetMap()\InitDone

InitDone is set to #True at the end of Webview2Controller_Created()
But I don't want to do this, because I maybe loose some Events.
