NAME
xcb_poly_line - draw lines SYNOPSIS
#include <xcb/xproto.h> Request function xcb_void_cookie_t xcb_poly_line(xcb_connection_t *conn, uint8_t coordinate_mode, xcb_drawable_t drawable, xcb_gcontext_t gc, uint32_t points_len, const xcb_point_t *points); REQUEST ARGUMENTS
conn The XCB connection to X11. coordinate_mode One of the following values: XCB_COORD_MODE_ORIGIN Treats all coordinates as relative to the origin. XCB_COORD_MODE_PREVIOUS Treats all coordinates after the first as relative to the previous coordinate. drawable The drawable to draw the line(s) on. gc The graphics context to use. points_len The number of xcb_point_t structures in points. points An array of points. DESCRIPTION
Draws points_len-1 lines between each pair of points (point[i], point[i+1]) in the points array. The lines are drawn in the order listed in the array. They join correctly at all intermediate points, and if the first and last points coincide, the first and last lines also join correctly. For any given line, a pixel is not drawn more than once. If thin (zero line-width) lines intersect, the intersecting pixels are drawn multiple times. If wide lines intersect, the intersecting pixels are drawn only once, as though the entire request were a single, filled shape. 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_poly_line_checked. See xcb-requests(3) for details. ERRORS
xcb_drawable_error_t TODO: reasons? xcb_gc_error_t TODO: reasons? xcb_value_error_t TODO: reasons? xcb_match_error_t TODO: reasons? EXAMPLE
/* * Draw a straight line. * */ void my_example(xcb_connection *conn, xcb_drawable_t drawable, xcb_gcontext_t gc) { xcb_poly_line(conn, XCB_COORD_MODE_ORIGIN, drawable, gc, 2, (xcb_point_t[]) { {10, 10}, {100, 10} }); xcb_flush(conn); } SEE ALSO

NAME
xcb_configure_window - Configures window attributes SYNOPSIS
#include <xcb/xproto.h> Request function xcb_void_cookie_t xcb_configure_window(xcb_connection_t *conn, xcb_window_t window, uint16_t value_mask, const uint32_t *value_list); 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. DESCRIPTION
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_window_error_t The specified window does not exist. TODO: any other reason? xcb_value_error_t TODO: reasons? xcb_match_error_t You specified a Sibling without also specifying StackMode or the window is not actually a Sibling. EXAMPLE
/* * Configures the given window to the left upper corner * with a size of 1024x768 pixels. * */ void my_example(xcb_connection *c, xcb_window_t window) { uint16_t mask = 0; mask |= XCB_CONFIG_WINDOW_X; mask |= XCB_CONFIG_WINDOW_Y; mask |= XCB_CONFIG_WINDOW_WIDTH; mask |= XCB_CONFIG_WINDOW_HEIGHT; const uint32_t values[] = { 0, /* x */ 0, /* y */ 1024, /* width */ 768 /* height */ }; xcb_configure_window(c, window, mask, values); xcb_flush(c); } SEE ALSO
