TWebView:Destroy method does not close the window.

[Antonio Linares]

Dear Hakan,

If that example is fine for you, ok. To me, the MDI environment is the right one to have multiple webviews running at the same time

Estimado César,

Si estás interesado en probar los últimos cambio, te envío las librerias. De momento solo se las he enviado a Hakan por que él está
muy activo probando webview

[cmsoft]

Si no es molestia, me gustaría probarlas...
Muchas gracias Antonio

Hi Antonio,

I have two version of TWebView examples that shows both "document.readyState"

First one is original FWH TWebView class with dialog container with your last sended fwh libs.

Code: Select all  Expand view  RUN

#include "FiveWin.ch"
function Main()
  local oWnd, oBar

   DEFINE WINDOW oWnd

   DEFINE BUTTONBAR oBar 3D OF oWnd SIZE 60, 60

   DEFINE BUTTON PROMPT "Open" OF oBar ACTION (Open_Google( oWnd ))

   ACTIVATE WINDOW oWnd

return nil

function Open_Google( oWnd )
LOCAL cHtml:="https://forums.fivetechsupport.com/ucp.php?mode=login&sid=12267e643672303281cdf64289c6875d"
local oWndChild, oWebView


  DEFINE WINDOW oWndChild TITLE "My Test FW Window_"+TIME() ;
    FROM 100, 100 TO 768, 1024 PIXEL

  oWndChild:bInit := <||
        oWebView := TWebView():New(,oWndChild:hWnd)
        oWebView:SetSize(oWndChild:nWidth, oWndChild:nHeight,0)
        oWebView:bOnBind = { | cJson, nCalls |  GetDataFrom_WebView( cJson, nCalls ) }
        oWebView:Bind( "SendToFWH" )       
        oWebView:Navigate(cHtml)
//      oWebView:Run()                              // We dont need when oWndChild
     Return Nil
  >
 
    oWndChild:bValid := <||
       oWebView:Destroy()
       Return .T.
    >
   
  ACTIVATE WINDOW oWndChild
   
  ? "I am here - Outside"


        cMyParam := ""
        cText := 'document.readyState'
        oWebView:Eval("SendToFWH( "+cText+")") 
        SysWait(2)
        ? cMyParam, "cMyParam - readyState'"
       
   
return nil

PROCEDURE GetDataFrom_WebView(cJson, nCalls)
    cMyParam := cJson
RETURN

Second one uses TOB_WebView class derived from original FWH TWebView class. It has only one method. (new method). It is exactly does same thing.

Problem is that first example show ["complete"]. This is exactly the expected data.
But second one there is not any read data even both example runs original Eval Method from FWH TWebView class, because there is not any derived Eval function. I gues

Can you help me please?

Hello, this code is from a class I was building. I posted it here just so it could be analyzed. The correct thing is you use the class that Linares is building. In the future I will also use the native fivewin class.

Yes Giavony, you are right. Much obliged. I just want to give this example to compare. What is different?

I don't know what the difference is because I don't have the 2206 version of fivewin. I'm using version 1909.

Hi Antonio,

Hi Antonio,

I found my mistake.

I used the WebView_Create function in the New method of my own class. So my class does not added to aWebView array that is used for to run Bind function.

I have changed CREATE_WEBVIEW() functions to ::Super:New(....). Sorry for making you unnecessarily busy.

This is full working my second example (Created with the idea taken from Giovany's examples.)

Dear Antonio,
What exactly do I need to download to test the TWebview examples out of the box.

Does it also work with xHarbour?

Best regards,
Otto

[Antonio Linares]

Dear Otto,

> What exactly do I need to download to test the TWebview examples out of the box.

Simply install FWH 22.06 then go to samples folder and do:
buildh webview
buildh webviewuni

> Does it also work with xHarbour?

Yes, 100% fully supported

[Otto]

Dear Antonio,
thank you so much and have a nice Sunday.

Otto
