本文介绍了如何绑定ESC键以关闭gWidgets中的`gwindow()`?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
考虑:
require(gWidgets2)
w <- gwindow("notebook example", visible=T)
nb <- gnotebook(container=w)
gbutton("Page one", label="tab 1", container=nb) ## note label argument
gbutton("Page two", label="tab 2", container=nb)
如何绑定给定键(例如ESC)以关闭gWidgets中的gwindow()，即执行dispose(w)?换句话说，如何在gWidget中分配键绑定?
How can I bind a given key (say, ESC) to close the gwindow() in gWidgets, that is to execute dispose(w)? In other words, how do you assign keybindings in gWidgets?
推荐答案
对于RGtk2(可能还有其他)，addHandlerKeystroke方法可用于捕获击键.您必须深入研究h对象以捕获ESC键.没有任何可移植的代码，但是Gtk文档应该能够提供帮助.
With RGtk2 (and possibly others) the addHandlerKeystroke method can be used to catch keystrokes. You have to dig into the h object to capture the ESC key. There isn't any portable code for that, but the Gtk docs should be able to help.
