[SOLVED] Re: input context attribute "XNFocusWindow"

[Lucien Gentis]

So I do Questions and Answers

I found a solution to my problem, but no explanation:

In the little program I joigned, I had to replace the line:

if (XSetLocaleModifiers("") == NULL) {

by

if (XSetLocaleModifiers("@im=none") == NULL) {

Output of prog-1 is now correct, and since I modified the application I am developing the same way, I can now type in characters with dead keys.

XSetLocaleModifiers man page don't give much details, and someone who could give an explanation of XSetLocaleModifiers("@im=none") would be welcome.

Cheers

Lucien
