The window_graphic(), widget_graphic(), root_graphic and image_graphic() functions return graphics for different GUI elements; windows, widgets, the root window (if the host system support it) or an in-memory image respectively. The set_fgcolor(), set_bgcolor(), set_pensize, set_penshape(), set_bitsmode(), set_fgalpha() and set_bgalpha() functions set the current values of the graphic properties; foreground color, background color, pen size, pen shape (PEN_SQUARE or PEN_ROUND) and bit transfer mode (BITS_COPY, BITS_INVERT, BITS_OR or BITS_XOR) respectively. The get_fgcolor(), get_bgcolor(), get_pensize, get_penshape(), get_bitsmode(), get_fgalpha() and get_bgalpha() functions return the current values for the graphic properties. |

The window_grphic(), widget_graphic(), root_graphic and image_graphic() functions all return a valid pointer to a graphic structure on success, or NULL on failure. The set_fgcolor(), set_bgcolor(), set_pensize(), set_penshape() , set_bitsmode(), set_fgalpha() and set_bgalpha() functions all return a the graphic pointer sent to them in the p_graph parameter on success, NULL on failure. The get_fgcolor(), get_bgcolor(), get_pensize(), get_penshape() , get_bitsmode(), get_fgalpha() and get_bgalpha() functions all return zero (0) on success, non-zero on failure. |
