Returns the difference between the union and the intersection of two regions.
This is a region containing the pixels that are in one of the source regions,
but which are not in both.
@source1: a #GdkRegion.
@source2: a #GdkRegion.
@Returns: the difference between the union and the intersection of @source1
and @source2.
Retrieves the motion history for a given device/window pair.
@window: a #GdkWindow.
@deviceid: the device for which to retrieve motion history.
@start: the start time.
@stop: the stop time.
@nevents_return: location to store the number of events returned.
@Returns: a newly allocated array containing all the events
from @start to @stop. This array should be freed
with g_free() when you are finished using it.
The #GdkDeviceInfo structure contains information about a
device. It has the following fields:
@deviceid: a unique integer ID for this device.
@name: the human-readable name for the device.
@source: the type of device.
@mode: a value indicating whether the device is enabled and
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
for each macro button.
Pango Interaction
Returns the union of two regions.
This is all pixels in either of @source1 or @source2.
@source1: a #GdkRegion.
@source2: a #GdkRegion.
@Returns: the union of @source1 and @source2.
Sets the key event generated when a macro button is pressed.
@deviceid: the device to configure.
@index: the index of the macro button.
@keyval: the key value for the #GdkKeypressEvent to generate.
(a value of 0 means no event will be generated.)
@modifiers: the modifier field for the generated
#GdkKeyPressEvent.
Lists all available input devices, along with their
configuration information.
@Returns: A #GList of #GdkDeviceInfo structures. This list
is internal data of GTK+ and should not be modified
or freed.
@GDK_PIXBUF_ALPHA_BILEVEL:
@GDK_PIXBUF_ALPHA_FULL:
Subtracts one region from another.
The result is a region containing all the pixels which are in @source1, but
which are not in @source2.
@source1: a #GdkRegion.
@source2: a #GdkRegion to subtract from @source1.
@Returns: @source1 - @source2.
Returns information about the current position of the pointer
within a window, including extended device information.
Any of the return parameters may be %NULL, in which case,
they will be ignored.
@window: a #GdkWindow.
@deviceid: a device ID.
@x: location to store current x postion.
@y: location to store current y postion.
@pressure: location to store current pressure.
@xtilt: location to store current tilt in the x direction.
@ytilt: location to store current tilt in the y direction.
@mask: location to store the current modifier state.
This macro contains an integer value representing
the device ID for the core pointer device.
Sets the mapping of the axes (valuators) of a device
onto the predefined valuator types that GTK+ understands.
@deviceid: the device to configure.
@axes: an array of GdkAxisUse. This length of this array
must match the number of axes for the device.
Sets the source type for a device.
@deviceid: the device to configure
@source: the new source type.
Points, Rectangles and Regions
Returns the intersection of two regions.
@source1: a #GdkRegion.
@source2: a #GdkRegion.
@Returns: the intersection of @source1 and @source2.
Enables or disables a device, and determines how the
device maps onto the screen.
@deviceid: the device to configure.
@mode: the new mode.
@Returns: %TRUE if the device supports the given mode, otherwise
%FALSE and the device's mode is unchanged.
