X11/XWindow更改属性代码

Posted 2022-01-08 柳鲲鹏

代码范例：

static void window_change_property()

    char* cname = NULL;
    XTextProperty tp;
    Atom atom;
    int32_t status;

    //atom = XInternAtom(g_pDisplay, "WM_NAME", True);
    atom = XInternAtom(g_pDisplay, "_NET_WM_NAME", True);

    cname = (char*)malloc(32);
    strcpy(cname, "Taishan");
    status = Xutf8TextListToTextProperty(g_pDisplay, &cname, 1, XStdICCTextStyle, &tp);
    if (status == Success || status > 0) 
        printf("%s-%d %s\\n", __func__, __LINE__, cname);
        XChangeProperty(g_pDisplay, g_oWindow, atom,
            tp.encoding, tp.format,
            PropModeReplace,
            tp.value,    tp.nitems);
    

    if (tp.value != NULL)
    
        XFree(tp.value);
