Hi,
The window of the WebView object creates a window. Is it possible to make the WebView open in a hidden form (without a window appearing on the screen) ?

You can make it children of another window so it will behave as a control
Or do you want it totally hidden ?

That's what I do. But this does not solve the problem of the window appearing (at least for 1 second) when creating a WebView

hi,
you can use "negative" Position at "Create" and later "move" to new Position / Parent

Dear Jimmy,
He won't be able to do that as WebView_Create() called from TWebView():New() does not allow the use of coordinates
Maybe this may work:
#define SW_HIDE 0
#define SW_NORMAL 1
local oWebView := TWebView():New()
ShowWindow( oWebView:GetWindow(), SW_HIDE )
... then do the required startup code and finally:
ShowWindow( oWebView:GetWindow(), SW_NORMAL )

Trying to execute this program:
The code block :bOnBind does not work. What am I doing wrong ?
- Code: Select all Expand view
- #include "FiveWin.ch"
function Main()
local oWebKds := TWebView():New()
oWebKds := TWebView():New()
oWebKds:bOnBind = { | cJson, nCalls | MsgInfo( cJson, nCalls ) }
oWebKds:Bind( "SendKds" )
cUrl:="https://www.google.com"
buf:='function Kds_Url() { SendKds(document.body.innerHTML) } ;'+CRLF+ ;
'window.location.href="'+cUrl+'" ;'+CRLF+ ;
'Kds_Url() ;'
DEFINE DIALOG oKds FROM 0,0 TO 400,400 PIXEL ;
STYLE nOR(WS_POPUP) COLOR CLR_BLACK, CLR_WHITE
ACTIVATE DIALOG oKds ON PAINT (oWebKds:SetParent(oKds), oWebKds:Eval(buf))
return

This works fine:
Are trying to add javascript code to an exiting web site ?
- Code: Select all Expand view
- #include "FiveWin.ch"
//----------------------------------------------------------------------------//
function Main()
local oWebView := TWebView():New()
oWebView:bOnBind = { | cJson, nCalls | MsgInfo( cJson, nCalls ) }
oWebView:Bind( "SendToFWH" )
oWebView:Navigate( Html() )
Sleep( 200 )
oWebView:Run()
oWebView:Destroy()
return nil
//----------------------------------------------------------------------------//
function Html()
local cHtml
TEXT INTO cHtml
data:text/html,
<html>
<head>
</head>
<body style="background-color:cyan">
<h2>Using WebView from FWH</h2>
<button onclick='SendToFWH( 123 )'>Call FWH app from web browser</button>
<button onclick='SendToFWH( 456 )'>Test 2</button>
<button onclick='SendToFWH( document.body.innerHTML )'>Test 3</button>
</body>
</html>
ENDTEXT
return cHtml

Another example using Class TWebView Method Eval():
- Code: Select all Expand view
- #include "FiveWin.ch"
//----------------------------------------------------------------------------//
function Main()
local oWebView := TWebView():New()
oWebView:bOnBind = { | cJson, nCalls | MsgInfo( cJson, nCalls ) }
oWebView:Bind( "SendToFWH" )
oWebView:Navigate( Html() )
Sleep( 200 )
oWebView:Eval( "SendToFWH( document.body.innerHTML )" )
oWebView:Run()
oWebView:Destroy()
return nil
//----------------------------------------------------------------------------//
function Html()
local cHtml
TEXT INTO cHtml
data:text/html,
<html>
<head>
</head>
<body style="background-color:cyan">
<h2>Using WebView from FWH</h2>
<button onclick='SendToFWH( 123 )'>Call FWH app from web browser</button>
<button onclick='SendToFWH( 456 )'>Test 2</button>
<button onclick='SendToFWH( document.body.innerHTML )'>Test 3</button>
</body>
</html>
ENDTEXT
return cHtml

Yes, I need to make frequent site requests and read the changes. This is a very convenient algorithm for me and I do not understand why in this case the code block :bonBind does not work 
the oWebKds:SetParent() method works, but the oWebKds:Eval() method does not
the oWebKds:SetParent() method works, but the oWebKds:Eval() method does not

Try with
- Code: Select all Expand view
ACTIVATE DIALOG oKds ON INIT ( oWebKds:SetParent(oKds), Sleep( 300 ) ) ON PAINT ( oWebKds:Eval(buf) )

Consider the following:
- The change in the content of the oWebView control does not cause the Paint event of the dialog to be executed
- In your javascript code, you are causing a recursive call to the same function.
I want to check that your code ( Eval() ) is executed? ( assuming there is no error in that code )
Change your code and resize dialog
If you want that function defined in ON PAINT to be executed, one of the possible options is to use a TIMER

I tried to write like this:
Three
windows appear:
1-DIALOG "Test"
2-webview with GOOGLE.COM
3-webview is empty
- Code: Select all Expand view
- #include "FiveWin.ch"
function Main()
local oWebKds := TWebView():New()
oWebKds := TWebView():New()
oWebKds:bOnBind = { | cJson, nCalls | MsgInfo( cJson, nCalls ) }
oWebKds:Bind( "SendKds" )
cUrl:="https://www.google.com"
buf:='function Kds_Url() { SendKds(document.body.innerHTML) } ;'+CRLF+ ;
'window.location.href="'+cUrl+'" ;'+CRLF+ ;
'document.addEventListener("DOMContentLoaded", Kds_Url()) ;'
DEFINE DIALOG oKds FROM 0,0 TO 400,400 PIXEL TRUEPIXEL RESIZABLE TITLE "Test"
ACTIVATE DIALOG oKds ON PAINT (sleep(200), oWebKds:Eval(buf))
return
