SYNTAX
int XDrawString(Display *_d_i_s_p_l_a_y, Drawable _d, GC
_g_c, int _x, int _y, char *_s_t_r_i_n_g, int
_l_e_n_g_t_h);
int XDrawString16(Display *_d_i_s_p_l_a_y, Drawable _d, GC
_g_c, int _x, int _y, XChar2b *_s_t_r_i_n_g, int
_l_e_n_g_t_h);
ARGUMENTS
-
_d
Specifies the drawable.
-
-
_d_i_s_p_l_a_y
Specifies the connection to the X server.
-
-
_g_c
Specifies the GC.
-
-
_l_e_n_g_t_h
Specifies the number of characters in the string argument.
-
-
_s_t_r_i_n_g
Specifies the character string.
-
and define the origin of the first character
-
_x
-
-
_y
Specify the x and y coordinates, which are relative to the origin of the specified drawable.
-
DESCRIPTION
Each character image, as defined by the font in the GC, is treated as an
additional mask for a fill operation on the drawable.
The drawable is modified only where the font character has a bit set to 1.
For fonts defined with 2-byte matrix indexing
and used with
_X_D_r_a_w_S_t_r_i_n_g_1_6,
each byte is used as a byte2 with a byte1 of zero.
Both functions use these GC components:
function, plane-mask, fill-style, font, subwindow-mode, clip-x-origin,
clip-y-origin, and clip-mask.
They also use these GC mode-dependent components:
foreground, background, tile, stipple, tile-stipple-x-origin,
and tile-stipple-y-origin.
_X_D_r_a_w_S_t_r_i_n_g
and
_X_D_r_a_w_S_t_r_i_n_g_1_6
can generate
_B_a_d_D_r_a_w_a_b_l_e,
_B_a_d_G_C,
and
_B_a_d_M_a_t_c_h
errors.
DIAGNOSTICS
-
_B_a_d_D_r_a_w_a_b_l_e
-
A value for a Drawable argument does not name a defined Window or Pixmap.
-
_B_a_d_G_C
-
A value for a GContext argument does not name a defined GContext.
-
_B_a_d_M_a_t_c_h
-
An
_I_n_p_u_t_O_n_l_y
window is used as a Drawable.
-
_B_a_d_M_a_t_c_h
-
Some argument or pair of arguments has the correct type and range but fails
to match in some other way required by the request.
