ARGUMENTS
-
_d_i_s_p_l_a_y

-
-
_p_r_o_p_e_r_t_y
Specifies the property name.
-
-
_t_e_x_t___p_r_o_p
Specifies the
-
_X_T_e_x_t_P_r_o_p_e_r_t_y
structure to be used.
-
_t_e_x_t___p_r_o_p___r_e_t_u_r_n

_X_T_e_x_t_P_r_o_p_e_r_t_y
structure.
DESCRIPTION
The
_X_S_e_t_T_e_x_t_P_r_o_p_e_r_t_y
function replaces the existing specified property for the named window
with the data, type, format, and number of items determined
by the value field, the encoding field, the format field,
and the nitems field, respectively, of the specified
_X_T_e_x_t_P_r_o_p_e_r_t_y
structure.
If the property does not already exist,
_X_S_e_t_T_e_x_t_P_r_o_p_e_r_t_y
sets it for the specified window.
_X_S_e_t_T_e_x_t_P_r_o_p_e_r_t_y
can generate
_B_a_d_A_l_l_o_c,
_B_a_d_A_t_o_m,
_B_a_d_V_a_l_u_e,
and
_B_a_d_W_i_n_d_o_w
errors.
The
_X_G_e_t_T_e_x_t_P_r_o_p_e_r_t_y
function reads the specified property from the window
and stores the data in the returned
_X_T_e_x_t_P_r_o_p_e_r_t_y
structure.
It stores the data in the value field,
the type of the data in the encoding field,
the format of the data in the format field,
and the number of items of data in the nitems field.
An extra byte containing null (which is not included in the nitems member)
is stored at the end of the value field of text_prop_return.
The particular interpretation of the property's encoding
and data as text is left to the calling application.
If the specified property does not exist on the window,
_X_G_e_t_T_e_x_t_P_r_o_p_e_r_t_y
sets the value field to NULL,
the encoding field to
_N_o_n_e,
the format field to zero,
and the nitems field to zero.
If it was able to read and store the data in the
_X_T_e_x_t_P_r_o_p_e_r_t_y
structure,
_X_G_e_t_T_e_x_t_P_r_o_p_e_r_t_y
returns a nonzero status;
otherwise, it returns a zero status.
_X_G_e_t_T_e_x_t_P_r_o_p_e_r_t_y
can generate
_B_a_d_A_t_o_m
and
_B_a_d_W_i_n_d_o_w
errors.
