Antonio, excuse me, I sent you an html file by email.

hb_DynCall( { "webview_navigate", pLib, ;
hb_bitOr( HB_DYN_CTYPE_VOID, hb_SysCallConv() ),;
HB_DYN_CTYPE_VOID_PTR, HB_DYN_CTYPE_CHAR_PTR },;
hWebView, "data:text/html,"+CRLF+filestr("my.html"))

Dear Yuri,

If you upload your HTML file to your hosting server and then use webview to navigate to it, it works fine. I just tested it.

But if we try to load it reading the file, then it crashes. Not sure why. We have noticed that with other HTML files too and still we
are wondering why.

[Antonio Linares]

In webview docs we find this:

// Navigates webview to the given URL. URL may be a properly encoded data URI.
// Examples:
// webview_navigate(w, "https://github.com/webview/webview");
// webview_navigate(w, "data:text/html,%3Ch1%3EHello%3C%2Fh1%3E");
// webview_navigate(w, "data:text/html;base64,PGgxPkhlbGxvPC9oMT4=");

Please notice that the HTML contents seems to be encoded. Maybe thats required.

Solved

oWebView:Navigate( "data:text/html;base64," + hb_base64Encode( hb_memoRead( "my.html" ) ) )

Antonio, thank you, the html file is loading normally. Only in webview, map rendering is much slower than in IE.

I tried to embed a webview object in a window. According to the documentation, the second webview_create parameter should be replaced with the window handle. However, it didn't work

Code: Select all  Expand view

function Main()
private pLib := hb_LibLoad( "webview.dll" )
private oWnd

   DEFINE DIALOG oWnd TITLE "FWH desktop app" SIZE 1000, 600

   ACTIVATE DIALOG oWnd  ON INIT CreateWebView() CENTER

   hb_LibFree( pLib )
return NIL

function CreateWebView
local hWebView

   hWebView := hb_DynCall( { "webview_create", pLib, ;
                 hb_bitOr( HB_DYN_CTYPE_VOID_PTR, hb_SysCallConv() ), ;
                 HB_DYN_CTYPE_VOID_PTR, hb_SysLong(), HB_DYN_CTYPE_VOID_PTR }, ;
                 oWnd:hWnd, 0)

   hb_DynCall( { "webview_navigate", pLib, ;
                 hb_bitOr( HB_DYN_CTYPE_VOID, hb_SysCallConv() ),;
                 HB_DYN_CTYPE_VOID_PTR, HB_DYN_CTYPE_CHAR_PTR },;
                 hWebView, "data:text/html;base64,"+ ;
                 hb_base64Encode(hb_memoread("my.html")))

   hb_DynCall( { "webview_run", pLib, ;
                 hb_bitOr( HB_DYN_CTYPE_VOID, hb_SysCallConv() ), ;
                 HB_DYN_CTYPE_VOID, HB_DYN_CTYPE_VOID_PTR }, hWebView )
return nil

You have to supply 0, 0 to WebView_Create(). It does not work using params there

But you can make it child of any other window using SetParent( webview_get_window( hWebView ), hWndParent )

[Natter]

Harbour doesn't understand this syntax:
webview_get_window( hWebView )

I tried to read the window handle, but I get empty.

hWebView := hb_DynCall( { "webview_create", pLib, ;
hb_bitOr( HB_DYN_CTYPE_VOID_PTR, hb_SysCallConv() ), ;
HB_DYN_CTYPE_VOID_PTR, hb_SysLong(), HB_DYN_CTYPE_VOID_PTR }, 0, 0)

hWb:=hb_DynCall( { "webview_get_window", pLib, ;
hb_bitOr( HB_DYN_CTYPE_VOID, hb_SysCallConv() ), ;
HB_DYN_CTYPE_VOID, HB_DYN_CTYPE_VOID_PTR }, hWebView )

Dear Yuri,

You need the new Class TWebView. It properly works with Borland, Microsoft, MinGW and xHarbour too

Its going to be available in a few days with the new FWH 22.06 version

Is it possible to install webview 2 runtime under Linux ?

[Antonio Linares]

From https://github.com/webview/webview:

It uses Cocoa/WebKit on macOS, gtk-webkit2 on Linux and Edge on Windows 10.

So it seems as it also works on Linux. I haven't tried it on Linux yet
