Creates a window.
Creates an unmapped window as child of the specified parent
window. A
CreateNotify event will be generated. The new window is placed on top in the
stacking order with respect to siblings.
The coordinate system has the X axis horizontal and the Y axis vertical with the origin [0, 0] at the upper-left corner. Coordinates are integral, in terms of pixels, and coincide with pixel centers. Each window and pixmap has its own coordinate system. For a window, the origin is inside the border at the inside, upper-left corner.
The created window is not yet displayed (mapped), call xcb_map_window
to
display it.
The created window will initially use the same cursor as its parent.
§Fields
wid
- The ID with which you will refer to the new window, created byxcb_generate_id
.depth
- Specifies the new window’s depth (TODO: what unit?).
The special value XCB_COPY_FROM_PARENT
means the depth is taken from the
parent
window.
visual
- Specifies the id for the new window’s visual.
The special value XCB_COPY_FROM_PARENT
means the visual is taken from the
parent
window.
class
-parent
- The parent window of the new window.border_width
- TODO:
Must be zero if the class
is InputOnly
or a xcb_match_error_t
occurs.
x
- The X coordinate of the new window.y
- The Y coordinate of the new window.width
- The width of the new window.height
- The height of the new window.
§Errors
Colormap
- TODO: reasons?Match
- TODO: reasons?Cursor
- TODO: reasons?Pixmap
- TODO: reasons?Value
- TODO: reasons?Window
- TODO: reasons?Alloc
- The X server could not allocate the requested resources (no memory?).

fn change_window_attributes<'c, 'input>( &'c self, window: Window, value_list: &'input ChangeWindowAttributesAux, ) -> Result<VoidCookie<'c, Self>, ConnectionError>
change window attributes.
Changes the attributes specified by value_mask
for the specified window
.
§Fields
window
- The window to change.value_mask

Destroys a window.
Destroys the specified window and all of its subwindows. A DestroyNotify event is generated for each destroyed window (a DestroyNotify event is first generated for any given window’s inferiors). If the window was mapped, it will be automatically unmapped before destroying.
Calling DestroyWindow on the root window will do nothing.

fn reparent_window( &self, window: Window, parent: Window, x: i16, y: i16, ) -> Result<VoidCookie<'_, Self>, ConnectionError>
Reparents a window.
Makes the specified window a child of the specified parent window. If the window is mapped, it will automatically be unmapped before reparenting and re-mapped after reparenting. The window is placed in the stacking order on top with respect to sibling windows.
After reparenting, a ReparentNotify event is generated.
§Fields

Sourcefn map_window(
&self,

fn map_window( &self, window: Window, ) -> Result<VoidCookie<'_, Self>, ConnectionError>
Makes a window visible.
Maps the specified window. This means making the window visible (as long as its parent is visible).
This MapWindow request will be translated to a MapRequest request if a window manager is running. The window manager then decides to either map the window or not. Set the override-redirect window attribute to true if you want to bypass this mechanism.
If the window manager decides to map the window (or if no window manager is running), a MapNotify event is generated.
If the window becomes viewable and no earlier contents for it are remembered, the X server tiles the window with its background. If the window’s background is undefined, the existing screen contents are not altered, and the X server generates zero or more Expose events.
If the window type is InputOutput, an Expose event will be generated when the window becomes visible. The normal response to an Expose event should be to repaint the window.

GrabPointer
: requestGrabButton
: requestEnterNotify

: event
Grab pointer button(s).
This request establishes a passive grab. The pointer is actively grabbed as described in GrabPointer, the last-pointer-grab time is set to the time at which the button was pressed (as transmitted in the ButtonPress event), and the ButtonPress event is reported if all of the following conditions are true:
The pointer is not grabbed and the specified button is logically pressed when the specified modifier keys are logically down, and no other buttons or modifier keys are logically down.
The grab-window contains the pointer.
The confine-to window (if any) is viewable.
A passive grab on the same button/key combination does not exist on any ancestor of grab-window.
The interpretation of the remaining arguments is the same as for GrabPointer. The active grab is terminated automatically when the logical state of the pointer has all buttons released, independent of the logical state of modifier keys. Note that the logical state of a device (as seen by means of the protocol) may lag the physical state if device event processing is frozen. This request overrides all previous passive grabs by the same client on the same button/key combinations on the same window. A modifier of AnyModifier is equivalent to issuing the request for all possible modifier combinations (including the combination of no modifiers). It is not required that all specified modifiers have currently assigned keycodes. A button of AnyButton is equivalent to issuing the request for all possible buttons. Otherwise, it is not required that the button specified currently be assigned to a physical button.
An Access error is generated if some other client has already issued a GrabButton request with the same button/key combination on the same window. When using AnyModifier or AnyButton, the request fails completely (no grabs are established), and an Access error is generated if there is a conflicting grab for any combination. The request has no effect on an active grab.

fn grab_keyboard<A>( &self, owner_events: bool, grab_window: Window, time: A, pointer_mode: GrabMode, keyboard_mode: GrabMode, ) -> Result<Cookie<'_, Self, GrabKeyboardReply>, ConnectionError>
Grab the keyboard.
Actively grabs control of the keyboard and generates FocusIn and FocusOut events. Further key events are reported only to the grabbing client.
Any active keyboard grab by this client is overridden. If the keyboard is
actively grabbed by some other client, AlreadyGrabbed
is returned. If
grab_window
is not viewable, GrabNotViewable
is returned. If the keyboard
is frozen by an active grab of another client, GrabFrozen
is returned. If the
specified time
is earlier than the last-keyboard-grab time or later than the
current X server time, GrabInvalidTime
is returned. Otherwise, the
last-keyboard-grab time is set to the specified time.

fn grab_key<A>( &self, owner_events: bool, grab_window: Window, modifiers: ModMask, key: A, pointer_mode: GrabMode, keyboard_mode: GrabMode, ) -> Result<VoidCookie<'_, Self>, ConnectionError>
Grab keyboard key(s).
Establishes a passive grab on the keyboard. In the future, the keyboard is
actively grabbed (as for GrabKeyboard
), the last-keyboard-grab time is set to
the time at which the key was pressed (as transmitted in the KeyPress event),
and the KeyPress event is reported if all of the following conditions are true:
The keyboard is not grabbed and the specified key (which can itself be a modifier key) is logically pressed when the specified modifier keys are logically down, and no other modifier keys are logically down.
Either the grab_window is an ancestor of (or is) the focus window, or the grab_window is a descendant of the focus window and contains the pointer.
A passive grab on the same key combination does not exist on any ancestor of grab_window.
The interpretation of the remaining arguments is as for XGrabKeyboard. The active grab is terminated automatically when the logical state of the keyboard has the specified key released (independent of the logical state of the modifier keys), at which point a KeyRelease event is reported to the grabbing window.
Note that the logical state of a device (as seen by client applications) may lag the physical state if device event processing is frozen.
A modifiers argument of AnyModifier is equivalent to issuing the request for all possible modifier combinations (including the combination of no modifiers). It is not required that all modifiers specified have currently assigned KeyCodes. A keycode argument of AnyKey is equivalent to issuing the request for all possible KeyCodes. Otherwise, the specified keycode must be in the range specified by min_keycode and max_keycode in the connection setup, or a BadValue error results.
If some other client has issued a XGrabKey with the same key combination on the same window, a BadAccess error results. When using AnyModifier or AnyKey, the request fails completely, and a BadAccess error results (no grabs are established) if there is a conflicting grab for any combination.

Draws text.
Fills the destination rectangle with the background pixel from gc
, then
paints the text with the foreground pixel from gc
. The upper-left corner of
the filled rectangle is at [x, y - font-ascent]. The width is overall-width,
the height is font-ascent + font-descent. The overall-width, font-ascent and
font-descent are as returned by xcb_query_text_extents
(TODO).
Note that using X core fonts is deprecated (but still supported) in favor of client-side rendering using Xft.

Allocate a color.
Allocates a read-only colormap entry corresponding to the closest RGB value supported by the hardware. If you are using TrueColor, you can take a shortcut and directly calculate the color pixel value to avoid the round trip. But, for example, on 16-bit color setups (VNC), you can easily get the closest supported RGB value to the RGB value you are specifying.

- The red value of your color.green
- The green value of your color.blue

create cursor.
Creates a cursor from a font glyph. X provides a set of standard cursor shapes in a special font named cursor. Applications are encouraged to use this interface for their cursors because the font can be customized for the individual display type.
All pixels which are set to 1 in the source will use the foreground color (as
specified by fore_red
, fore_green
and fore_blue
). All pixels set to 0
will use the background color (as specified by back_red
, back_green
and
back_blue
).
§Fields
cid
- The ID with which you will refer to the cursor, created byxcb_generate_id
.source_font
- In which font to look for the cursor glyph.mask_font
- In which font to look for the mask glyph.source_char
- The glyph ofsource_font
to use.mask_char
- The glyph ofmask_font
to use as a mask: Pixels which are set to 1 define which source pixels are displayed. All pixels which are set to 0 are not displayed.fore_red
- The red value of the foreground color.fore_green
- The green value of the foreground color.fore_blue
- The blue value of the foreground color.back_red
- The red value of the background color.back_green
- The green value of the background color.back_blue
- The blue value of the background color.

check if extension is present.
Determines if the specified extension is present on this X11 server.
Every extension has a unique major_opcode
to identify requests, the minor
opcodes and request formats are extension-specific. If the extension provides
events and errors, the first_event
and first_error
fields in the reply are
set accordingly.
There should rarely be a need to use this request directly, XCB provides the
xcb_get_extension_data
function instead.
§Fields
name_len
- The length ofname
in bytes.name
- The name of the extension to query, for example “RANDR”. This is case sensitive!

Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
