Request function

xcb_void_cookie_t xcb_poly_segment(xcb_connection_t *conn, xcb_drawable_t drawable, xcb_gcontext_t gc, uint32_t segments_len, const xcb_segment_t *segments); |
|
conn |
The XCB connection to X11. |
|||
|
drawable |
A drawable (Window or Pixmap) to draw on. |
|||
|
gc |
The graphics context to use. |
TODO: document which attributes of a gc are used
segments_len
The number of xcb_segment_t structures in segments.
|
segments |
An array of xcb_segment_t structures. |
Draws multiple, unconnected lines. For each segment, a line is drawn between (x1, y1) and (x2, y2). The lines are drawn in the order listed in the array of xcb_segment_t structures and does not perform joining at coincident endpoints. For any given line, a pixel is not drawn more than once. If lines intersect, the intersecting pixels are drawn multiple times.
TODO: include the xcb_segment_t data structure
TODO: an example
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_segment_checked. See xcb-requests(3) for details.
xcb_drawable_error_t
The specified drawable does not exist.
xcb_gc_error_t
The specified gc does not exist.
xcb_match_error_t
