Struct xcb::x::CwMask [−][src]
pub struct CwMask { /* fields omitted */ }
Implementations
Overrides the default background-pixmap. The background pixmap and window must have the same root and same depth. Any size pixmap can be used, although some sizes may be faster than others.
If XCB_BACK_PIXMAP_NONE
is specified, the window has no defined background.
The server may fill the contents with the previous screen contents or with
contents of its own choosing.
If XCB_BACK_PIXMAP_PARENT_RELATIVE
is specified, the parent’s background is
used, but the window must have the same depth as the parent (or a Match error
results). The parent’s background is tracked, and the current version is
used each time the window background is required.
Overrides BackPixmap
. A pixmap of undefined size filled with the specified
background pixel is used for the background. Range-checking is not performed,
the background pixel is truncated to the appropriate number of bits.
Overrides the default border-pixmap. The border pixmap and window must have the same root and the same depth. Any size pixmap can be used, although some sizes may be faster than others.
The special value XCB_COPY_FROM_PARENT
means the parent’s border pixmap is
copied (subsequent changes to the parent’s border attribute do not affect the
child), but the window must have the same depth as the parent.
Overrides BorderPixmap
. A pixmap of undefined size filled with the specified
border pixel is used for the border. Range checking is not performed on the
border-pixel value, it is truncated to the appropriate number of bits.
Defines which region of the window should be retained if the window is resized.
Defines how the window should be repositioned if the parent is resized (see
ConfigureWindow
).
A backing-store of WhenMapped
advises the server that maintaining contents of
obscured regions when the window is mapped would be beneficial. A backing-store
of Always
advises the server that maintaining contents even when the window
is unmapped would be beneficial. In this case, the server may generate an
exposure event when the window is created. A value of NotUseful
advises the
server that maintaining contents is unnecessary, although a server may still
choose to maintain contents while the window is mapped. Note that if the server
maintains contents, then the server should maintain complete contents not just
the region within the parent boundaries, even if the window is larger than its
parent. While the server maintains contents, exposure events will not normally
be generated, but the server may stop maintaining contents at any time.
The backing-planes indicates (with bits set to 1) which bit planes of the window hold dynamic data that must be preserved in backing-stores and during save-unders.
The backing-pixel specifies what value to use in planes not covered by backing-planes. The server is free to save only the specified bit planes in the backing-store or save-under and regenerate the remaining planes with the specified pixel value. Any bits beyond the specified depth of the window in these values are simply ignored.
The override-redirect specifies whether map and configure requests on this window should override a SubstructureRedirect on the parent, typically to inform a window manager not to tamper with the window.
If 1, the server is advised that when this window is mapped, saving the contents of windows it obscures would be beneficial.
The event-mask defines which events the client is interested in for this window (or for some event types, inferiors of the window).
The do-not-propagate-mask defines which events should not be propagated to ancestor windows when no client has the event type selected in this window.
The colormap specifies the colormap that best reflects the true colors of the window. Servers capable of supporting multiple hardware colormaps may use this information, and window man- agers may use it for InstallColormap requests. The colormap must have the same visual type and root as the window (or a Match error results). If CopyFromParent is specified, the parent’s colormap is copied (subsequent changes to the parent’s colormap attribute do not affect the child). However, the window must have the same visual type as the parent (or a Match error results), and the parent must not have a colormap of None (or a Match error results). For an explanation of None, see FreeColormap request. The colormap is copied by sharing the colormap object between the child and the parent, not by making a complete copy of the colormap contents.
If a cursor is specified, it will be used whenever the pointer is in the window. If None is speci- fied, the parent’s cursor will be used when the pointer is in the window, and any change in the parent’s cursor will cause an immediate change in the displayed cursor.
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
Safety
The caller of the bitflags!
macro can chose to allow or
disallow extra bits for their bitflags type.
The caller of from_bits_unchecked()
has to ensure that
all bits correspond to a defined flag or that extra bits
are valid for this bitflags type.
Returns true
if there are flags common to both self
and other
.
Returns true
if all of the flags in other
are contained within self
.
Inserts or removes the specified flags depending on the passed value.
Returns the intersection between the flags in self
and
other
.
Specifically, the returned set contains only the flags which are
present in both self
and other
.
This is equivalent to using the &
operator (e.g.
ops::BitAnd
), as in flags & other
.
Returns the union of between the flags in self
and other
.
Specifically, the returned set contains all flags which are
present in either self
or other
, including any which are
present in both (see Self::symmetric_difference
if that
is undesirable).
This is equivalent to using the |
operator (e.g.
ops::BitOr
), as in flags | other
.
Returns the difference between the flags in self
and other
.
Specifically, the returned set contains all flags present in
self
, except for the ones present in other
.
It is also conceptually equivalent to the “bit-clear” operation:
flags & !other
(and this syntax is also supported).
This is equivalent to using the -
operator (e.g.
ops::Sub
), as in flags - other
.
Returns the symmetric difference between the flags
in self
and other
.
Specifically, the returned set contains the flags present which
are present in self
or other
, but that are not present in
both. Equivalently, it contains the flags present in exactly
one of the sets self
and other
.
This is equivalent to using the ^
operator (e.g.
ops::BitXor
), as in flags ^ other
.
Returns the complement of this set of flags.
Specifically, the returned set contains all the flags which are
not set in self
, but which are allowed for this type.
Alternatively, it can be thought of as the set difference
between Self::all()
and self
(e.g. Self::all() - self
)
This is equivalent to using the !
operator (e.g.
ops::Not
), as in !flags
.
