[英]How to programmatically set custom folder icon in GNOME?
Because I know that a simple API call handles setting the custom folder icons in Windows, I looked for an API method to set custom folder icons in Linux. 因为我知道一个简单的API调用可以处理Windows中的自定义文件夹图标设置,所以我寻找了一种API方法来设置Linux中的自定义文件夹图标。
But in this thread , I saw that there is no such a way. 但是在这个线程中 ,我看到没有这种方法。 Also I learnt that each desktop environment has its own way to set custom folder icons.
我还了解到,每个桌面环境都有自己的设置自定义文件夹图标的方式。 The way of KDE is clearly described there.
在那里清楚地描述了KDE的方式。
For GNOME I looked for a similar way; 对于GNOME,我寻求一种类似的方法。 but no file is created when setting the folder's icon from the properties panel.
但从属性面板设置文件夹的图标时,不会创建文件。 I think there should be a registry-like file in somewhere in the user home or /etc.
我认为在用户主目录或/ etc中的某个位置应该有一个类似注册表的文件。
I will be glad, if you kill my pain. 如果您能消除痛苦,我会很高兴。 Thanks.
谢谢。
I finally figured out how to do this! 我终于想出了该怎么做! Here's a Python script that works in the standard Gnome environment:
这是在标准Gnome环境中工作的Python脚本:
#!/usr/bin/env python
import sys
from gi.repository import Gio
if len(sys.argv) not in (2, 3):
print 'Usage: {} FOLDER [ICON]'.format(sys.argv[0])
print 'Leave out ICON to unset'
sys.exit(0)
folder = Gio.File.new_for_path(sys.argv[1])
icon_file = Gio.File.new_for_path(sys.argv[2]) if len(sys.argv) == 3 else None
# Get a file info object
info = folder.query_info('metadata::custom-icon', 0, None)
if icon_file is not None:
icon_uri = icon_file.get_uri()
info.set_attribute_string('metadata::custom-icon', icon_uri)
else:
# Change the attribute type to INVALID to unset it
info.set_attribute('metadata::custom-icon',
Gio.FileAttributeType.INVALID, '')
# Write the changes back to the file
folder.set_attributes_from_info(info, 0, None)
