from hulahop.webview import WebView
import xpcom
from xpcom.components import interfaces

gobject.threads_init()

HOME = "file:///home/olpc/Activities/Grade4.activity/index.html";

class Grade4Activity(activity.Activity):
    def __init__(self, handle):
        activity.Activity.__init__(self, handle)

        self.props.max_participants = 1

        self._web_view = WebView()

        toolbox = activity.ActivityToolbox(self)
        self.set_toolbox(toolbox)
        toolbox.show()

        toolbar = Toolbar(self._web_view)
        toolbox.add_toolbar(_('Navigation'), toolbar)
        toolbar.show()

        self.set_canvas(self._web_view)
        self._web_view.show()

        toolbox.set_current_toolbar(1)

        self._web_view.load_uri(HOME)

class Toolbar(gtk.Toolbar):
    def __init__(self, web_view):
        gobject.GObject.__init__(self)

        self._web_view = web_view

        self._back = ToolButton('go-previous-paired')
        self._back.set_tooltip(_('Back'))
        self._back.props.sensitive = False
        self._back.connect('clicked', self._go_back_cb)
        self.insert(self._back, -1)
        self._back.show()

        self._forward = ToolButton('go-next-paired')
        self._forward.set_tooltip(_('Forward'))
        self._forward.props.sensitive = False
        self._forward.connect('clicked', self._go_forward_cb)
        self.insert(self._forward, -1)
        self._forward.show()

        home = ToolButton('zoom-home')
        home.set_tooltip(_('Home'))
        home.connect('clicked', self._go_home_cb)
        self.insert(home, -1)
        home.show()

        self._listener = xpcom.server.WrapObject(ProgressListener(self),

interfaces.nsIWebProgressListener)
        weak_ref = xpcom.client.WeakReference(self._listener)

        mask = interfaces.nsIWebProgress.NOTIFY_STATE_NETWORK | \
               interfaces.nsIWebProgress.NOTIFY_LOCATION
        self._web_view.web_progress.addProgressListener(self._listener,
mask)

    def update_navigation_buttons(self):
        can_go_back = self._web_view.web_navigation.canGoBack
        self._back.props.sensitive = can_go_back

        can_go_forward = self._web_view.web_navigation.canGoForward
        self._forward.props.sensitive = can_go_forward

    def _go_back_cb(self, button):
        self._web_view.web_navigation.goBack()

    def _go_forward_cb(self, button):
        self._web_view.web_navigation.goForward()

    def _go_home_cb(self, button):
        self._web_view.web_navigation.goBack()

class ProgressListener(object):
    _com_interfaces_ = interfaces.nsIWebProgressListener

    def __init__(self, toolbar):
        self._toolbar = toolbar

    def onLocationChange(self, webProgress, request, location):
        self._toolbar.update_navigation_buttons()

    def onProgressChange(self, webProgress, request, curSelfProgress,
                         maxSelfProgress, curTotalProgress,
maxTotalProgress):
        pass

    def onSecurityChange(self, webProgress, request, state):
        pass

    def onStateChange(self, webProgress, request, stateFlags, status):
        if stateFlags & interfaces.nsIWebProgressListener.STATE_IS_NETWORK:
            self._toolbar.update_navigation_buttons()

    def onStatusChange(self, webProgress, request, status, message):
        pass
