Hi to all,
My system : Linux - Ubuntu 14.04
I am developing an application which relies on Xlib Library and I try to
internationalize it.
In order to be able to type in accented character, some of them with
dead keys, I use XmbLookupString function and a unique Input Context.
Since my app has several X windows, each time one of them gets input
focus, I must set "XNFocusWindow" attribute to it through XSetICValues
function, but it doesn't seem to work:
If "w" is the X window I want to set as "XNFocusWindow" attribute of the
IC, when I reread this attribute through XGetICValues function, I don't
obtain the same value:
XSetICValues(ic,XNFocusWindow,w,NULL);
Window winicfocus;
XGetICValues(ic,XNFocusWindow,&winicfocus,NULL);
printf ("Window w id : %ld - IC focus window : %ld\n",w,winicfocus);
I get:
Window w id : 77594625 - IC focus window : 0
To illustrate that, I have joined a little programme you should compile
through this command:
gcc -g -Wall prog-1.cc -o prog-1 -lX11
