Check for window focus

[TonyF]

Is it possible to check if the window is focused or not eg tabbed out?

 

Some googling indicated in leadwerks 2 AppSuspended() was used however i cant seem to find a leadwerks 3 versions.

 

Im basically trying to stop moving the mouse when the window isnt active

So basically this dosnt exist yet?

 

I would have thought alt-tabbing is a common need at some stage or another.

Thanks to this, something like this should work

 

EDIT: I installed XUbuntu 14.04 on dual-boot to test this, below is the working version

bool isActiveWindow(Leadwerks::Window* window)

{

if( window == nullptr )

return false;

 

#if defined(__linux__) && !defined(__ANDROID__)

::Window root = 0L;

::Window active = 0L;

Atom _NET_ACTIVE_WINDOW = XInternAtom(window->display, "_NET_ACTIVE_WINDOW", False);

Atom actual_type;

int actual_format;

unsigned long count, bytesAfter;

unsigned char* properties = NULL;

 

root = DefaultRootWindow(window->display);

if( XGetWindowProperty(window->display, root, _NET_ACTIVE_WINDOW, 0L, sizeof(::Window), False, XA_WINDOW, &actual_type, &actual_format, &count, &bytesAfter, &properties) == Success )

{

active = *reinterpret_cast<::Window*>(properties);

XFree(properties);

}

 

return (window->window == active);

#else

return window->Active();

#endif

}

Yes it is. And that's why it's very strange why it isn't implemented yet.
