1 /* input-method-xfs.c provides just only locale initialize
|
|
|
2 for non Motif people. (stoled from input-method-xlib.c)
|
|
|
3 Why I made this code is to initialize X locale environment for
|
|
|
4 the purpose of use XFontSet correctly in lwlib/xlwmenu.c.
|
|
|
5 And this code donot provides input methods under Xlib while they
|
|
|
6 prefer to use Canna, Wnn, skk or something like that.
|
|
|
7 This code has been tested on FreeBSD 2.2.1 and Solaris2.5.
