Raise/Map and Focus a window: BadMatch error

[Andrew Troschinetz]

Hello everyone,

I'm struggling with xlib here since I've been given a project that  
requires a lot of low level window management and I've never really  
done any coding with xlib before now. Currently I have an issue with  
XSetInputFocus().

What I'm trying to do is write a function that will:
	1. Map a window (if it's unmapped)
	2. Raise it
	3. Focus that window

Here's what I've got thus far:

void map_raise_focus(Display *display, Window window) {
	XEvent e;
	XSelectInput (display, windw, ExposureMask);
	XMapRaised (display, window);
	while (e.type != Expose) {
		XNextEvent (display, &e);
	}
	XSelectInputFocus (display, window, RevertToParent, CurrentTime);
}

Sometimes (not always) I get a BadMatch error (Details: serial 2738  
error_code 8 request_code 42 minor_code 0) which I'm sure is being  
caused by my XSelectInputFocus() call. I have a feeling that I'm doing  
something very wrong here but looking at the docs I can't seem to  
figure out how one would go about writing a function like  
map_raise_focus().

Can anyone shed some light on this problem for me please?
