GtkTreeView 的行激活和光标更改信号
我有一个树视图，我正在观察 cursor-changed 和 row-activated 信号。问题是，为了触发行激活，我首先必须单击该行（触发 cursor-changed），然后双击，需要单击 3 次。
有没有办法通过两次点击来响应这两个信号？
I have a treeview and I am watching for the cursor-changed and row-activated signals. The problem is that in order to trigger the row-activate I first have to click on the row (triggering cursor-changed) and then do the double click, requiring 3 clicks.
Is there a way to respond to both signals with 2 clicks?

目前还不清楚你想要实现什么目标。我猜您正在尝试响应用户更改树视图中的选择。
如果是这种情况，请连接到
gtk.TreeSelection上的[changed][1]信号：据我所知，使用林间空地这是不可能的界面设计师。
但是，如果您完全尝试做其他事情，请添加更多信息。
It's not very clear what you're trying to achieve. I guess you're trying to respond to the user changing the selection in the treeview.
If this is the case, connect to the
[changed][1]signal on thegtk.TreeSelection:As far as I can tell, this is not possible using the glade interface designer.
If, however, you are trying to do something else entirely, please add some more information.
即使单击同一（选定）行，也会发出
cursor-changed信号。尽管如此，当您双击一行时，无论是否在双击之前选择了该行，都会发出row-activated信号。因此，您不需要点击 3 次即可触发行激活。正如 Jon 提到的，您想要连接到选择的
changed信号，而不是cursor-changed。The
cursor-changedsignal is emitted even when single clicking on the same (selected) row. Still, therow-activatedsignal is emitted when you double click on a row, whether it was selected before the double click or not. Thus you don't need 3 clicks to trigger arow-activated.As Jon mentioned, you want to connect to the selection's
changedsignal in stead ofcursor-changed.
