Member Function Documentation

static void Gst::Navigation::add_interface ( GType  gtype_implementer  )  [static]
const GstNavigation* Gst::Navigation::gobj (  )  const [inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Gst::XImageSink, and Gst::XvImageSink.

GstNavigation* Gst::Navigation::gobj (  )  [inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Gst::XImageSink, and Gst::XvImageSink.

void Gst::Navigation::send_command ( Gst::NavigationCommand  command  ) 

Sends the indicated command to the navigation interface.

Since gstreamermm 0.10:
.23
Parameters:
command The command to issue.
void Gst::Navigation::send_event ( Gst::Structure structure  ) 
virtual void Gst::Navigation::send_event_vfunc ( Gst::Structure structure  )  [virtual]

Called when an event has been sent to the Gst::Navigation.

void Gst::Navigation::send_key_event ( const Glib::ustring event,
const Glib::ustring key 
)
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.

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.
