![在操作系统之间同步桌面图标位置](https://linux22.com/image/1505168/%E5%9C%A8%E6%93%8D%E4%BD%9C%E7%B3%BB%E7%BB%9F%E4%B9%8B%E9%97%B4%E5%90%8C%E6%AD%A5%E6%A1%8C%E9%9D%A2%E5%9B%BE%E6%A0%87%E4%BD%8D%E7%BD%AE.png)
我有一个 Windows 10/Arch Linux 双启动设置。我已将两个系统配置为使用同一个桌面(只是符号链接/home/rawing/Desktop
到D:/Users/Rawing/Desktop
)。它运行正常,我可以访问两个系统上的所有文件,但我想同步桌面上文件的位置。例如,如果我在 Linux 上创建一个新文件并将其移动到桌面的右下角,Windows 仍会在左上角显示新文件,迫使我第二次重新定位文件。
有没有办法同步桌面上文件的位置?
答案1
每个操作系统的图标位置存储方式不同。您无法在 Windows 和 Linux 之间共享图标位置。
答案2
我取得了一些进展,想与大家分享一下。这还不是一个完整、可行的答案,但我已经扫清了一些障碍。
适用于 Linux 的 Python3 脚本:
def get_icon_positions_linux():
desktop= os.path.join(os.path.expanduser('~'), 'Desktop')
icons= {}
#try to find out the screen resolution
resolution= get_screen_resolution()
for name in os.listdir(desktop):
path= os.path.join(desktop, name)
data= subprocess.getoutput("gvfs-info -a 'metadata::nautilus-icon-position' "+shlex.quote(path))
if not data:
continue
match= re.search(r'(\d+),(\d+)\s*$', data)
x, y= int(match.group(1)), int(match.group(2))
if resolution is not None:
x/= resolution[0]
y/= resolution[1]
icons[name]= (x,y)
return icons
def set_icon_positions_linux(icons):
desktop= os.path.join(os.path.expanduser('~'), 'Desktop')
for name,(x,y) in icons.items():
path= os.path.join(desktop, name)
pos= ','.join(map(str, (x,y)))
subprocess.call(['gvfs-set-attribute', '-t', 'string', path, 'metadata::nautilus-icon-position', pos])
#FIXME: refresh desktop
和 Windows:
def get_icon_positions_windows():
# retrieves icon locations from the Windows registry. More info can be found here:
# https://superuser.com/questions/625854/where-does-windows-store-icon-positions
#FIXME: before doing anything, make explorer save the current positions
import winreg
icons= {}
key= winreg.OpenKey(winreg.HKEY_CURRENT_USER, r'Software\Microsoft\Windows\Shell\Bags\1\Desktop')
#find the key with the current screen resolution
resolution= get_screen_resolution()
valuename= 'ItemPos'+ 'x'.join(map(str, resolution))
for index in range(1024):
value= winreg.EnumValue(key, index)
if value[0].startswith(valuename):
break
#parse the icon locations
data= value[1]
#first 16 bytes are junk
data= data[0x10:]
format= 'HHIHHH'
name_offset= struct.calcsize(format)
while True:
# What they call "unknown padding" is exactly what we're looking for.
x, y= struct.unpack_from('II', data) # (x,y) in pixels on the Desktop from the top left corner.
data= data[8:]
if len(data)<name_offset:
break
size, flags, filesize, date, time, fileattrs= struct.unpack_from(format, data)
if size==0:
break
chunk= data[:size]
data= data[size:]
if size>=0x15:
chunk= chunk[name_offset:]
name= chunk[:chunk.find(b'\0')].decode()
icons[name]= (x/resolution[0], y/resolution[1])
return icons

subprocess.Popen(r'start %WINDIR%\explorer.exe"', shell=True)
该代码目前存在以下问题:
get_icon_positions_windows
不强制 Windows 资源管理器保存当前图标位置。它会创建最后保存位置的快照。set_icon_positions_linux
不刷新桌面。您可能需要按 F5 才能使更改生效。
这个想法是,无论用户何时注销或登录,都使用此代码将图标位置写入文件或从文件中加载图标位置。遗憾的是,我还没有找到在 Windows 上注销时运行命令的方法。(参见我的另一个问题)
