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

724 given face. If cursor is true, draw a cursor around the string.

727 The meaning of the parameters is something like this:
|
|
|
728
|
|
|
729 W Window that the text is to be displayed in.
|
|
|
730 DL Display line that this text is on. The values in the
|
|
|
731 structure are used to determine the vertical position and
|
|
|
732 clipping range of the text.
|
|
|
733 BUF Dynamic array of Emchars specifying what is actually to be
|
|
|
734 drawn.
|
|
|
735 XPOS X position in pixels where the text should start being drawn.
|
|
|
736 XOFFSET Number of pixels to be chopped off the left side of the
|
|
|
737 text. The effect is as if the text were shifted to the
|
|
|
738 left this many pixels and clipped at XPOS.
|
|
|
739 CLIP_START Clip everything left of this X position.
|
|
|
740 WIDTH Clip everything right of XPOS + WIDTH.
|
|
|
741 FINDEX Index for the face cache element describing how to display
|
|
|
742 the text.
|
|
|
743 CURSOR #### I don't understand this. There's something
|
|
|
744 strange and overcomplexified with this variable.
|
|
|
745 Chuck, explain please?
|
|
|
746 CURSOR_START Starting X position of cursor.
|
|
|
747 CURSOR_WIDTH Width of cursor in pixels.
|
|
|
748 CURSOR_HEIGHT Height of cursor in pixels.
|
|
|
749
|
|
|
750 Starting Y position of cursor is the top of the text line.
|
|
|
751 The cursor is drawn sometimes whether or not CURSOR is set. ???
