85 /* Note: We do not use the Xmb*() functions and XFontSets.
|
|
|
86 Those functions are generally losing for a number of reasons:
|
|
183
|
87
|
|
0
|
88 1) They only support one locale (e.g. you could display
|
|
|
89 Japanese and ASCII text, but not mixed Japanese/Chinese
|
|
|
90 text). You could maybe call setlocale() frequently
|
|
|
91 to try to deal with this, but that would generally
|
|
|
92 fail because an XFontSet is tied to one locale and
|
|
|
93 won't have the other character sets in it.
|
|
|
94 2) Not all (or even very many) OS's support the useful
|
|
|
95 locales. For example, as far as I know SunOS and
|
|
|
96 Solaris only support the Japanese locale if you get the
|
|
|
97 special Asian-language version of the OS. Yuck yuck
|
|
|
98 yuck. Linux doesn't support the Japanese locale at
|
|
|
99 all.
|
|
|
100 3) The locale support in X only exists in R5, not in R4.
|
|
|
101 (Not sure how big of a problem this is: how many
|
|
|
102 people are using R4?)
|
|
|
103 4) Who knows if the multi-byte text format (which is locale-
|
|
|
104 specific) is even the same for the same locale on
|
|
|
105 different OS's? It's not even documented anywhere that
|
|
|
106 I can find what the multi-byte text format for the
|
|
|
107 Japanese locale under SunOS and Solaris is, but I assume
|
|
|
108 it's EUC.

747 BUF Dynamic array of Emchars specifying what is actually to be

748 drawn.

749 XPOS X position in pixels where the text should start being drawn.
|
|
|
750 XOFFSET Number of pixels to be chopped off the left side of the
|

752 left this many pixels and clipped at XPOS.
