Detailed Description
A Gdk::Device instance contains a detailed description of an extended input device.Public Member Functions | |

Discover whether the pointer follows device motion. | |
bool | get_history (const Glib::RefPtr<Window>& window, guint32 start, guint32 stop, GdkTimeCoord**& events, int& n_events) |
Obtains the motion history for a device; given a starting and ending timestamp, return all events in the motion history for the device in the given range of time. | |

bool Gdk::Device::get_axis | ( | double & | axes, | |
AxisUse | use, | |||
double & | value | |||
) | const |
Interprets an array of double as axis values for a given device, and locates the value in the array for a given axis use.
- Parameters:
-
axes Pointer to an array of axes. use The use to look for. value Location to store the found value.
- Returns:
true
if the given axis use was found, otherwisefalse
.
bool Gdk::Device::get_has_cursor | ( | ) | const |
Discover whether the pointer follows device motion.
- Returns:
- true if the pointer follows device motion.
bool Gdk::Device::get_history | ( | const Glib::RefPtr<Window>& | window, | |
guint32 | start, | |||
guint32 | stop, | |||
GdkTimeCoord **& | events, | |||
int & | n_events | |||
) |
Obtains the motion history for a device; given a starting and ending timestamp, return all events in the motion history for the device in the given range of time.
Some windowing systems do not support motion history, in which case, false
will be returned. (This is not distinguishable from the case where motion history is supported and no events were found.)
- Parameters:
-
window The window with respect to which which the event coordinates will be reported. start Starting timestamp for range of events to return. stop Ending timestamp for the range of events to return. events Location to store a newly-allocated array of Gdk::TimeCoord, or 0
.n_events Location to store the length of events, or 0
.
- Returns:
true
if the windowing system supports motion history and at least one event was found.
InputMode Gdk::Device::get_mode | ( | ) | const |
Gets the mode of this device.
- Returns:
- The mode of this device.
Glib::ustring Gdk::Device::get_name | ( | ) | const |
Gets the name of this device.
- Returns:
- The name of this device.
InputSource Gdk::Device::get_source | ( | ) | const |
Gets the type of this device.
- Returns:
- The type of this device.

Glib::RefPtr<Gdk::Device> wrap | ( | GdkDevice * | 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.
