您可以使用C，从而列出所有窗口:
/*
Window *getDisplayWindows (Display *disp, unsigned long *len);
Window *getDisplayWindows (Display *disp, unsigned long *len) {
Atom prop = XInternAtom(disp,"_NET_CLIENT_LIST",False), type;
int form;
unsigned long remain;
unsigned char *list;
if (XGetWindowProperty(disp,XDefaultRootWindow(disp),prop,0,1024,False,XA_WINDOW,
&type,&form,len,&remain,&list) != Success) {
return 0;
}
return (Window*)list;
}
*/
import "C"
//your go code below
我用这个作为package of mine，把一个窗口放在前景.希望这会有帮助？
