|
|
how the device coordinates map to the screen.
|
|
@has_cursor: if %TRUE, a cursor will be displayed indicating
|
|
the current on-screen location to the user. Otherwise,
|

the application is responsible for drawing a cursor
|
|
itself.
|
|
@num_axes: the number of axes for this device.
|
|
@axes: a pointer to an array of GdkAxisUse values which
|
|
give the mapping of axes onto the possible valuators
|
|
for a GDK device.
|
|
@num_keys: the number of macro buttons.
|
|
@keys: a pointer to an array of #GdkDeviceKey structures
|
|
which describe what key press events are generated
