[Done] PB V4.70B1 - No luck with the WebGadget()

[Guimauve]

Hello everyone,

Apparently, I don't have any luck with the WebGadget(). As reported by Fred, the WebGadget() on Linux should work. If it's true, can someone tell me why the Debugger tell me :

The WebGadget() don't work !

when I run this tiny source code :

Code: Select all

If OpenWindow(0,0,0,600,300,"WebGadget",#PB_Window_SystemMenu|#PB_Window_ScreenCentered)
  
  WebGadget(0,10,10,580,280,"http://www.purebasic.com")
  
  If IsGadget(0)
    Debug "The WebGadget() work !"
  Else
    Debug "The WebGadget() not work !"
  EndIf
  
  Repeat
  Until WaitWindowEvent() = #PB_Event_CloseWindow
  
EndIf 

The WebGadget() is now based on Webkit libs but which one ? This is the installed lib list about Webkit GTK

• libwebkitgtk-1.0-common --> 1.8.1-0ubuntu0.12.04.1
  libwebkitgtk-3.0-common --> 1.8.1-0ubuntu0.12.04.1
  libwebkitgtk-3.0-0 --> 1.8.1-0ubuntu0.12.04.1
  libwebkitgtk-1.0-0 --> 1.8.1-0ubuntu0.12.04.1
  gir1.2-webkit-3.0 --> 1.8.1-0ubuntu0.12.04.1

Something else is needed ?

PureBasic V4.70 Beta 1 x64
LinuxMint 13 x64 + Gnome-Shell 3.4.2

Guillaume: so you have a lib named "libwebkitgtk-1.0-0.so" ? If yes, please try this new lib: www.purebasic.com/beta/linux_x64/gadgetweb

Edit :

With the new librairy, the WebGadget() finally work but I get a [WARNING] DEBUG: NP_Initialize succeeded

[Fred]

It's a warning which comes from the lib, sounds more like a debug message than a warning anyway.

@Fred

Nothing to worry about, fine and thanks your work.

This WebKit warning is displayed if the embedding of scripting lanuages is enabled which is the WebKit default setting. By disabling the embedding of scripts the above warning will disappear:

Code: Select all

#G_TYPE_INT = 6 << 2

ImportC "-lwebkitgtk-1.0"
  webkit_web_settings_new()
  webkit_web_view_set_settings(*WebkitWebView, *WebkitSettings)
EndImport

Define Value.GValue

OpenWindow(0, 200, 100, 600, 300, "WebGadget")
WebGadget(0, 10, 10, 580, 280, "http://www.purebasic.com")

; ----- Get current webkit settings
WebkitSettings = webkit_web_settings_new()

; ----- Disable embedding of scripting languages
Value\g_type = #G_TYPE_INT
g_value_set_int_(Value, 0)
g_object_set_property_(WebkitSettings, "enable-scripts", @Value)

; ----- Store changed settings
webkit_web_view_set_settings(GadgetID(0), WebkitSettings)

Repeat 
Until WaitWindowEvent() = #PB_Event_CloseWindow

How would that be for gtk3? when I use this code the debugger crashes with a message that mixing gtk2 and gtk3 symbols is not allowed.

OK found it, "-lwebkitgtk-3.0" should be used.

It may have been mentioned already, but to simply load a html string into the WebGadget on Linux a workaround is needed, like:

Code: Select all

ImportC "-lwebkitgtk-3.0" ; should be 3, not 1
  webkit_web_settings_new()
  webkit_web_view_load_string(*WebView, Content.P-UTF8, *MIMEType, *Encoding, *BaseURI)
  webkit_web_view_set_settings(*WebkitWebView, *WebkitSettings)
EndImport

Procedure WebGadgetText(gadget.l, html.s)
  ; replaces SetGadgetText for the WebGadget in Linux to set/change text
  webkit_web_view_load_string(GadgetID(gadget), html, 0, 0, 0)
  WebkitSettings = webkit_web_settings_new()
  webkit_web_view_set_settings(GadgetID(gadget), WebkitSettings)
EndProcedure

I pulled this from the net and adjusted it a little. Seems to work fine. But I suppress debug warnings. There's no harm, but they are annoying.
