An interface for elements that provide navigation functionality.
§ Navigation()
Gst::Navigation::Navigation |
( |
| ) |
|
|
protected |
You should derive from this class to use it.
§ ~Navigation()
virtual Gst::Navigation::~Navigation |
( |
| ) |
|
|
virtual |
§ add_interface()
static void Gst::Navigation::add_interface |
( |
GType |
gtype_implementer | ) |
|
|
static |
§ get_type()
static GType Gst::Navigation::get_type |
( |
| ) |
|
|
static |
Get the GType for this class, for use with the underlying GObject type system.
§ gobj() [1/2]
GstNavigation* Gst::Navigation::gobj |
( |
| ) |
|
|
inline |
Provides access to the underlying C GObject.
§ gobj() [2/2]
const GstNavigation* Gst::Navigation::gobj |
( |
| ) |
const |
|
inline |
Provides access to the underlying C GObject.
§ send_command()
Sends the indicated command to the navigation interface.
- Parameters
-
command | The command to issue. |
§ send_event()
§ send_event_vfunc()
virtual void Gst::Navigation::send_event_vfunc |
( |
Gst::Structure& |
structure | ) |
|
|
virtual |
§ send_key_event()
void Gst::Navigation::send_key_event |
( |
const Glib::ustring & |
event, |
|
|
const Glib::ustring & |
key |
|
) |
| |
- Parameters
-
event | The type of the key event. Recognised values are "key-press" and "key-release". |
key | Character representation of the key. This is typically as produced by XKeysymToString. |
§ send_mouse_event()
void Gst::Navigation::send_mouse_event |
( |
const Glib::ustring & |
event, |
|
|
int |
button, |
|
|
double |
x, |
|
|
double |
y |
|
) |
| |
Sends a mouse event to the navigation interface.
Mouse event coordinates are sent relative to the display space of the related output area. This is usually the size in pixels of the window associated with the element implementing the Gst::Navigation interface.
- Parameters
-
event | The type of mouse event, as a text string. Recognised values are "mouse-button-press", "mouse-button-release" and "mouse-move". |
button | The button number of the button being pressed or released. Pass 0 for mouse-move events. |
x | The x coordinate of the mouse event. |
y | The y coordinate of the mouse event. |
§ wrap()
Glib::RefPtr< Gst::Navigation > wrap |
( |
GstNavigation * |
object, |
|
|
bool |
take_copy = false |
|
) |
| |
|
related |
A Glib::wrap() method for this object.
- Parameters
-
object | The C instance. |
take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
- Returns
- A C++ instance that wraps this C instance.
