Re: [Vala] Question on Documentation and tutorials.

Hi,

you may use dbus to get the plug message from Hal. And then you may
tell Hal to mount the volume.

The best way to understand is to look at source :
http://svn.gnome.org/viewvc/gnome-volume-manager/trunk/src/manager.c?rview=markup
    * gvm_dbus_init (void)
    * gvm_hal_init (void)

The second fonction register callback from an Hal event :
        libhal_ctx_set_device_added (ctx, hal_device_added);
        libhal_ctx_set_device_removed (ctx, hal_device_removed);
        libhal_ctx_set_device_new_capability (ctx, hal_device_new_capability);
        libhal_ctx_set_device_lost_capability (ctx, hal_device_lost_capability);
        libhal_ctx_set_device_property_modified (ctx, hal_property_modified);

Quit big to read but very interressant.
