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

743 DL Display line that this text is on. The values in the

744 structure are used to determine the vertical position and

745 clipping range of the text.
|

746 BUF Dynamic array of Emchars specifying what is actually to be
|
|
|
747 drawn.
|
|

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

753 WIDTH Clip everything right of XPOS + WIDTH.
|
|
|
754 FINDEX Index for the face cache element describing how to display
|
|
|
755 the text.

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

757 strange and overcomplexified with this variable.

758 Chuck, explain please?

759 CURSOR_START Starting X position of cursor.
