error: ‘BadDevice’ was not declared in this scope - c++

Question

any idea why I would be getting this error?:
error: ‘BadDevice’ was not declared in this scope
I have included:
#include <X11/Xlib.h>
and
#include <X11/extensions/XInput2.h>
in my class header file.
I am using it like this:
int ret = XIGrabDevice(display_, 2, LinuxInputManager::getWindow(),
CurrentTime, None, GrabModeAsync,
GrabModeAsync, False, &eventMask_);
if (ret == BadValue)
std::cout << "bad value" << std::endl;
else if (ret == BadDevice)
std::cout << "BadDevice" << std::endl;
if (ret == BadMatch)
std::cout << "BadMatch" << std::endl;
if (ret == BadWindow)
std::cout << "BadWindow" << std::endl;
if (ret) {
std::cout << "not available 3" << std::endl;
}
Cheers

Answer 1

This is how you use it
int rc;
if ((rc = XIGrabDevice(dpy, 2, win, CurrentTime, None, GrabModeAsync,
GrabModeAsync, False, &mask)) != GrabSuccess)
{
fprintf(stderr, "Grab failed with %d\n", rc);
return;
}
or try (also try with your functions)
int rc;
if (!(rc = XIGrabDevice(dpy, 2, win, CurrentTime, None, GrabModeAsync,
GrabModeAsync, False, &mask)))
{
fprintf(stderr, "Grab failed with %d\n", rc);
return;
}
It appears that either BadValue, BadDevice, BadMatch... will be an int value, and they might not be defined in the header files so I would check to make sure they are there somewhere. So, try to cout the ret variable. Your error codes might be something like 1, 2, 3, 4 or they could be 1 or 0. You make have to define the error codes yourself.
Here is an example program of how someone else used XIGrabDevice: http://people.freedesktop.org/~whot/xi2-recipes/part5.c
