[英]scroll TextView in ScrolledWindow so that cursor is visible in pyGTK2
I have a Textview in a ScrolledWindow. 我在ScrolledWindow中有一个Textview。 I have set up a callback on signal "changed" of textbuffer of the textview.
我已经在textview的textbuffer的信号“ changed”上设置了一个回调。 Now I need to scroll the ScrolledWindow to the point of the cursor.
现在,我需要将ScrolledWindow滚动到光标的位置。 How do I do that?
我怎么做?
self.outgoing = gtk.ScrolledWindow()
self.outgoing.set_policy(gtk.POLICY_AUTOMATIC, gtk.POLICY_AUTOMATIC)
self.textview = gtk.TextView()
textbuffer=self.textview.get_buffer()
textbuffer.connect("changed",self.scrolltocursor)
self.outgoing.add_with_viewport(self.textview)
def scrolltocursor(self,text_buffer):
<I don't know what to do here>
Help please. 请帮助。
Well it seems the problem was that I did add_with_viewport
to put the textview in the scrolled window. 好吧,看来问题是我做了
add_with_viewport
来将textview放在滚动窗口中。 Now I tried self.outgoing.add(self.textview)
and it works without any callbacks to change. 现在,我尝试了
self.outgoing.add(self.textview)
,它可以正常工作而无需更改任何回调。 So yeah. 是的。 That fixes it.
那就解决了。
