如何使用gio和python3获取文件的图标

问题描述 投票:0回答:1

我想使用gtk获取相应文件的默认图标。

我在python3中尝试了此方法,但给了我一个错误

from gi.repository import Gio as gio
from gi.repository import Gtk
import os

def get_icon_filename(filename,size):
    #final_filename = "default_icon.png"
    final_filename = ""
    if os.path.isfile(filename):
        # Get the icon name
        file = gio.File(filename)
        file_info = file.query_info('standard::icon')
        file_icon = file_info.get_icon().get_names()[0]
        # Get the icon file path
        icon_theme = gtk.icon_theme_get_default()
        icon_filename = icon_theme.lookup_icon(file_icon, size, 0)
        if icon_filename != None:
            final_filename = icon_filename.get_filename()

    return final_filename


print(get_icon_filename("/home/newtron/Desktop/Gkite_Logo.png",64))

Err

  File "geticon", line 11, in get_icon_filename
    file = gio.File(filename)
TypeError: GInterface.__init__() takes exactly 0 arguments (1 given)

我以前没有gio模块的经验。我的代码有什么问题吗?如果没有,该错误的解决方案是什么。

python-3.x gtk3 gio

正如我的朋友@ stovfl所说,这是因为我在python2中使用了旧的Gi和Gtk代码。但是在新版本的gio.File中,属性具有更多子属性(类),这些子属性指定了给出的文件属性类型,例如

new_for_path类,我在代码中使用了它并对其进行了处理。实际上,我是从另一个StackOverflow讨论中得到的。

当我再次检查它时,它具有python3代码

#!/usr/bin/env python
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gio as gio
from gi.repository import Gtk as gtk
import os

def get_icon_filename(filename,size):
    #final_filename = "default_icon.png"
    final_filename = ""
    if os.path.isfile(filename):
        # Get the icon name
        file = gio.File.new_for_path(filename)
        file_info = file.query_info('standard::icon',0)
        file_icon = file_info.get_icon().get_names()[0]
        # Get the icon file path
        icon_theme = gtk.IconTheme.get_default()
        icon_filename = icon_theme.lookup_icon(file_icon, size, 0)
        if icon_filename != None:
            final_filename = icon_filename.get_filename()

    return final_filename


print(get_icon_filename("/home/newtron/Desktop/counter.desktop",48))
