Interprets an array of double as axis values for a given device, and locates the value in the array for a given axis use.
axes | Pointer to an array of axes. |
use | The use to look for. |

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.)

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 nullptr . |
n_events | Location to store the length of events, or nullptr . |
true
if the windowing system supports motion history and at least one event was found. void Gdk::Device::get_key | ( | guint | index_, |
guint & | keyval, | ||
ModifierType& | modifiers | ||

If index_ has a valid keyval, this function will fill in keyval and modifiers with the keyval settings.
index_ | The index of the macro button to get. |
keyval | Return value for the keyval. |
modifiers | Return value for modifiers. |
