|
|
|
78 Those functions are generally losing for a number of reasons:
|
|
|
79
|
|
|
80 1) They only support one locale (e.g. you could display
|
|
|
81 Japanese and ASCII text, but not mixed Japanese/Chinese
|
|
|
82 text). You could maybe call setlocale() frequently
|
|
|
83 to try to deal with this, but that would generally
|
|
|
84 fail because an XFontSet is tied to one locale and
|
|
|
85 won't have the other character sets in it.
|
|
|
86 2) Not all (or even very many) OS's support the useful
|
|
|
87 locales. For example, as far as I know SunOS and
|
|
|
88 Solaris only support the Japanese locale if you get the
|
|
|
89 special Asian-language version of the OS. Yuck yuck
|
|
|
90 yuck. Linux doesn't support the Japanese locale at
|
|
|
91 all.
|
|
|
92 3) The locale support in X only exists in R5, not in R4.
|
|
|
93 (Not sure how big of a problem this is: how many
|
|
|
94 people are using R4?)
|
|
|
95 4) Who knows if the multi-byte text format (which is locale-
|
|
|
96 specific) is even the same for the same locale on
|
|
|
97 different OS's? It's not even documented anywhere that
|
|
|
98 I can find what the multi-byte text format for the
|
|
|
99 Japanese locale under SunOS and Solaris is, but I assume
|
|
|
100 it's EUC.

748 BUF Dynamic array of Ichars specifying what is actually to be
|
|
428
|
749 drawn.
|

750 XPOS X position in pixels where the text should start being drawn.
|
|
|
751 XOFFSET Number of pixels to be chopped off the left side of the
|
|
|
752 text. The effect is as if the text were shifted to the
|
|
|
753 left this many pixels and clipped at XPOS.

754 CLIP_START Clip everything left of this X position.
|

755 WIDTH Clip everything right of XPOS + WIDTH.
|

756 FINDEX Index for the face cache element describing how to display

757 the text.

758 CURSOR #### I don't understand this. There's something
