如何将一个项目添加到GTK的“最近使用的” Python的文件列表? [英] How does one add an item to GTK's "recently used" file list from Python?
问题描述
我能够成功读取 >最近使用的文件列表如下所示:
from gi.repository import Gtk
recent_mgr = Gtk.RecentManager.get_default ()
for item in recent_mgr.get_items():
print(item.get_uri())
这会打印出我在Nautilus中查看Recent时看到的相同文件列表,或查看GIMP等应用程序的文件对话框中的Recently Used位置。
然而,当我尝试添加这样的项目时(其中 /home/laurence/foo/bar.txt
是现有的文本文件) ...
recent_mgr.add_item('file:///home/laurence/foo/bar.txt')
...该文件不会显示在Nautilus的最新部分或文件对话框中。它甚至不会显示在由 get_items()
返回的结果中。

A Gtk.RecentManager
需要发出已更改
信号,以便将更新写入C ++类的专用属性中。要在应用程序中使用 RecentManager
对象,您需要通过调用 Gtk.main
来启动事件循环:
from gi.repository import Gtk
recent_mgr = Gtk.RecentManager.get_default()
uri = r'file:/ path / to / my / file'
recent_mgr.add_item(uri)
Gtk.main()

I am able to successfully read the recently used file list like this: This prints out the same list of files I see when I look at "Recent" in Nautilus, or look at the "Recently Used" place in the file dialog of apps like GIMP.

,更改$ c $
RecentManager.add_item
返回布尔值是因为调用了 g_file_query_info_async
函数。回调函数 gtk_recent_manager_add_item_query_info
然后将mimetype,应用程序名称和命令收集到 GtkRecentData
struct中,最后调用 gtk_recent_manager_add_full
。来源是此处。
add_item
已完成,那么方法只返回 True
如果调用的对象是 RecentManager
,并且uri不是 NULL
;和 False
,否则。
TRUE
如果新项目已成功添加到最近使用的资源列表中
TRUE
仅意味着调用异步函数来处理添加新项目。
from gi.repository import Gtk,GObject
recent_mgr = Gtk .RecentManager.get_default()
uri = r'file:/ path / to / my / file'
recent_mgr.add_item(uri)
GObject.idle_add(Gtk.main_quit)
Gtk.main()
from gi.repository import Gtk
recent_mgr = Gtk.RecentManager.get_default()
for item in recent_mgr.get_items():
print(item.get_uri())
/home/laurence/foo/bar.txt
is an existing text file)...recent_mgr.add_item('file:///home/laurence/foo/bar.txt')
get_items()
.Gtk.RecentManager
needs to emit the changed
signal for the update to be written in a private attribute of the C++ class. To use a RecentManager
object in an application, you need to start the event loop by calling Gtk.main
:from gi.repository import Gtk
recent_mgr = Gtk.RecentManager.get_default()
uri = r'file:/path/to/my/file'
recent_mgr.add_item(uri)
Gtk.main()
Gtk.main()
, the changed
signal is not emitted and nothing happens.RecentManager.add_item
returns a boolean is because the g_file_query_info_async
function is called. The callback function gtk_recent_manager_add_item_query_info
then gathers the mimetype, application name and command into a GtkRecentData
struct and finally calls gtk_recent_manager_add_full
. The source is here.add_item
has finished, so the method just returns True
if the object it is called from is a RecentManager
and if the uri is not NULL
; and False
otherwise.
TRUE
if the new item was successfully added to the recently used resources listTRUE
only means that an asynchronous function was called to deal with the addition of a new item.from gi.repository import Gtk, GObject
recent_mgr = Gtk.RecentManager.get_default()
uri = r'file:/path/to/my/file'
recent_mgr.add_item(uri)
GObject.idle_add(Gtk.main_quit)
Gtk.main()
