Guys, can you please check if this helps rxvt to have a tab?

	Display *focusDisplay = XOpenDisplay(NULL);
	int param = 0;
	int xid = XGetInputFocus(focusDisplay,&focusWindow,&param);

Hi dima,

Thanks for 'inspiring' me, to fix this issue that also annoyed me for some time. The xid is already available, my main function now contains:

    // make sure that rxvt is shown in a tab
    ipc_set_services();
    ipc_sys_startup_complete(rxvt_vars->TermWin.parent[0]);

    rxvt_main_loop(rxvt_vars);	/* main processing loop */

The keyboard is still displayed when switching to other applications, but that will not be a big problem I hope. To make this work I also had to change the code to remove the keyboard. When calling eripc_sysd_startup_complete() to show the application in the taskbar, sysd checks to see if the process-id that is given as parameter is equal to one of the processes that is started from the UI. The original code was using a shell-script to start the real rxvt-program, so the pid of the program started, did not match with the pid of the process calling startup_complete().
I modified the code slightly to close the keyboard when the program exits, so I do not need the shell-script anymore.

I see if I can make a proper 'installation package' and post it in the original rxvt message thread.
