xcb_configure_window(3)

xcb_configure_window3

Configures window attributes

Request arguments

conn

The XCB connection to X11.

window

The window to configure.

value_mask

Bitmask of attributes to change.

value_list

New values, corresponding to the attributes in value_mask. The order has to correspond to the order of possible value_mask bits. See the example.

Overview

Configures a window's size, position, border width and stacking order.

Return value

Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the event loop.

If you want to handle errors directly with xcb_request_check instead, use xcb_configure_window_checked. See xcb-requests(3) for details.

Errors

xcb_match_error_t

You specified a Sibling without also specifying StackMode or the window is not actually a Sibling.

xcb_value_error_t

TODO: reasons?

xcb_window_error_t

The specified window does not exist. TODO: any other reason?

Examples

/*
 * Configures the given window to the left upper corner
 * with a size of 1024x768 pixels.
 *
