This function allows the applications to get USB devices filtered by the devices' classes. The applications that are going to use this function should provide a list of USB devices class code (based on http://www.usb.org/developers/defined_class), then the function will create a string in the expcted format, representing the filter, and call spice_usb_device_manager_get_devices_with_filter() --- doc/reference/spice-gtk-sections.txt | 1 + gtk/map-file | 1 + gtk/spice-glib-sym-file | 1 + gtk/usb-device-manager.c | 45 ++++++++++++++++++++++++++++++++++++ gtk/usb-device-manager.h | 2 ++ 5 files changed, 50 insertions(+) diff --git a/doc/reference/spice-gtk-sections.txt b/doc/reference/spice-gtk-sections.txt index caaa92c..03dcec3 100644 --- a/doc/reference/spice-gtk-sections.txt +++ b/doc/reference/spice-gtk-sections.txt @@ -298,6 +298,7 @@ SpiceUsbDeviceManagerClass spice_usb_device_manager_get spice_usb_device_manager_get_devices spice_usb_device_manager_get_devices_with_filter +spice_usb_device_manager_get_devices_by_classes spice_usb_device_manager_is_device_connected spice_usb_device_manager_disconnect_device spice_usb_device_manager_can_redirect_device diff --git a/gtk/map-file b/gtk/map-file index 90f14f1..0a31dc0 100644 --- a/gtk/map-file +++ b/gtk/map-file @@ -110,6 +110,7 @@ spice_usb_device_manager_connect_device_finish; spice_usb_device_manager_disconnect_device; spice_usb_device_manager_get; spice_usb_device_manager_get_devices; +spice_usb_device_manager_get_devices_by_classes; spice_usb_device_manager_get_devices_with_filter; spice_usb_device_manager_get_type; spice_usb_device_manager_is_device_connected; diff --git a/gtk/spice-glib-sym-file b/gtk/spice-glib-sym-file index 878dd12..3c5a785 100644 --- a/gtk/spice-glib-sym-file +++ b/gtk/spice-glib-sym-file @@ -85,6 +85,7 @@ spice_usb_device_manager_connect_device_finish spice_usb_device_manager_disconnect_device spice_usb_device_manager_get spice_usb_device_manager_get_devices +spice_usb_device_manager_get_devices_by_classes spice_usb_device_manager_get_devices_with_filter spice_usb_device_manager_get_type spice_usb_device_manager_is_device_connected diff --git a/gtk/usb-device-manager.c b/gtk/usb-device-manager.c index 5013b6c..7e65991 100644 --- a/gtk/usb-device-manager.c +++ b/gtk/usb-device-manager.c @@ -1379,6 +1379,51 @@ GPtrArray* spice_usb_device_manager_get_devices(SpiceUsbDeviceManager *self) } /** + * spice_usb_device_manager_get_devices_by_classes: + * @manager: the #SpiceUsbDeviceManager manager + * @classes: (element-type gint) (allow-none): a %GList of classes for selecting + * which devices to return or %NULL + * + * Returns: (element-type SpiceUsbDevice) (transfer full): a %GPtrArray array of %SpiceUsbDevice + * + * Since: 0.26 + */ +GPtrArray* spice_usb_device_manager_get_devices_by_classes(SpiceUsbDeviceManager *self, + GList *classes) +{ + GPtrArray *devices; + GList *l; + gchar *filter = NULL; + + /* Builds the filter based on the USB classes received from the user.
