-
- +o Be sure that you link libXm _b_e_f_o_r_e libXt. Failure to
- do so is a programmer error that will result in a
- mysterious core dump. The reason for this is because
- libXm and libXt both have a _V_e_n_d_o_r_S_h_e_l_l widget. It is
- important that the one from libXm is the first one the
- loader encounters.
-
- +o It is far more efficient (both in terms of memory use
- and speed) to use _X_t_S_e_t_V_a_l_u_e_s to set up a large
- scrolled list than to use _X_m_L_i_s_t_A_d_d_I_t_e_m_s with the same
- array of list items.
-
- +o Of the two drag-and-drop protocols in use
- (_p_r_e_r_e_g_i_s_t_e_r_e_d and _d_y_n_a_m_i_c), Silicon Graphics _s_t_r_o_n_g_l_y
- suggests that you stick to the dynamic protocol:
-
- - Only the dynamic protocol is being standardized at
- the X Consortium ICCCM level.
-
- - The preregistered protocol has known logical
- problems, connected with the source needing to
- draw into the destination's window. If that
- window is a different visual, it isn't always
- handled correctly.
-
- - Because of the need to keep a drop site database
- up to date, some performance problems are caused
- by using the preregistered protocol.
-
- +o There are some known demo program shortcomings:
-
- helloint Trying to use Japanese & Hebrew
- fonts gives warnings
-
- motifburger Order dialog geometry management
- not set right.
-
- view Core dumps trying "C" locale.
