在 GTK 中转发按键
我正在为 Gedit 插件编写一些代码。我使用的是 Python，接口（显然）是 GTK。
所以，我遇到的问题非常简单：我有一个搜索框（gtk.Entry），在下面我有一个结果框（gtk.TreeView）。在搜索框中输入内容后，您会立即看到一堆结果，我希望用户能够按向上/向下键选择一个，然后按 Enter 键选择它，然后完成。问题是，我似乎找不到将向上/向下按键转发到 TreeView 的方法。目前我有这段代码：
def __onSearchKeyPress(self, widget, event):
"""
Forward up and down keys to the tree.
"""
if event.keyval in [gtk.keysyms.Up, gtk.keysyms.Down]:
print "pressed up or down"
e = gtk.gdk.Event(gtk.gdk.KEY_PRESS)
e.keyval = event.keyval
e.window = self.browser.window
e.send_event = True
self.browser.emit("key-press-event", e)
return True
我可以清楚地看到我正在接收正确类型的事件，但我发送的事件被 TreeView 忽略。有什么想法吗？
预先感谢人们。
I'm writing a bit of code for a Gedit plugin. I'm using Python and the interface (obviously) is GTK.
So, the issue I'm having is quite simple: I have a search box (a gtk.Entry) and right below I have a results box (a gtk.TreeView). Right after you type something in the search box you are presented a bunch of results, and I would like the user to be able to press the Up/Down keys to select one, Enter to choose it, and be done. Thing is, I can't seem to find a way to forward the Up/Down keypress to the TreeView. Currently I have this piece of code:
def __onSearchKeyPress(self, widget, event):
"""
Forward up and down keys to the tree.
"""
if event.keyval in [gtk.keysyms.Up, gtk.keysyms.Down]:
print "pressed up or down"
e = gtk.gdk.Event(gtk.gdk.KEY_PRESS)
e.keyval = event.keyval
e.window = self.browser.window
e.send_event = True
self.browser.emit("key-press-event", e)
return True
I can clearly see I'm receiving the right kind of event, but the event I'm sending gets ignored by the TreeView. Any ideas?
Thanks in advance people.

这不是问题的正确答案（我不知道如何转发按键），但有另一种解决方案可以解决您的问题。
直接操作 TreeView 光标/选择，例如：
Not a proper answer to the question (I don't know how to forward key presses), but there's an alternative solution to your problem.
Manipulate the TreeView cursor/selection directly, for example:
您是否将
key-press-event包含在小部件允许接收的事件列表中？您可以通过致电来做到这一点Did you include the
key-press-eventin the list of events the widget is allowed to receive? You can do that by calling
