[Xcb] what events need to be handled to show a window

[Micah Nordland]

I think that only map requests and configure requests should have to be
handled, but apparently, X thinks differently.

I have these two event handlers. I'm writing a window manager, using xcb
and c++11.

void handleMapRequest(xcb_generic_event_t* event)
{
    xcb_map_request_event_t* ev = (xcb_map_request_event_t *) event;
    xcb_void_cookie_t err = xcb_map_window_checked(global::conf.conn,
ev->window);
    if(xcb_request_check(conn, err))
    {
        std::cout << "we had a problem mapping this window" << std::endl;
    }
    std::cout << "window " << ev->window << " has been mapped" << std::endl;
}

void handleConfigureRequest(xcb_generic_event_t* event)
{
    uint16_t mask=0;
    uint32_t values [7];
    unsigned short i = 0;

    xcb_configure_request_event_t* ev = (xcb_configure_request_event_t *)
event;

    if (ev->value_mask & XCB_CONFIG_WINDOW_X)
    {
        mask |= XCB_CONFIG_WINDOW_X;
        values[i++] = ev->x;
    }

    if (ev->value_mask & XCB_CONFIG_WINDOW_Y)
    {
        mask |= XCB_CONFIG_WINDOW_Y;
        values[i++] = ev->y;
    }

    if (ev->value_mask & XCB_CONFIG_WINDOW_WIDTH)
    {
        mask |= XCB_CONFIG_WINDOW_WIDTH;
        values[i++] = ev->width;
    }

    if (ev->value_mask & XCB_CONFIG_WINDOW_HEIGHT)
    {
        mask |= XCB_CONFIG_WINDOW_HEIGHT;
        values[i++] = ev->height;
    }

    if (ev->value_mask & XCB_CONFIG_WINDOW_BORDER_WIDTH)
    {
        mask |= XCB_CONFIG_WINDOW_BORDER_WIDTH;
        values[i++] = ev->border_width;
    }

    if (ev->value_mask & XCB_CONFIG_WINDOW_SIBLING)
    {
        mask |= XCB_CONFIG_WINDOW_SIBLING;
        values[i++] = ev->sibling;
    }

    if (ev->value_mask & XCB_CONFIG_WINDOW_STACK_MODE)
    {
        mask |= XCB_CONFIG_WINDOW_STACK_MODE;
        values[i++] = ev->stack_mode;
    }

    xcb_void_cookie_t err = xcb_configure_window_checked(global::conf.conn,
ev->window, mask, values);

    if (xcb_request_check(conn, err))
    {
        std::cout << "there was a problem configuring this window" <<
std::endl;
    }

    std::cout <<"window " << ev->window << " was configured"<< std::endl;
}
