如何绑定ESC键以关闭gWidgets中的`gwindow()`? [英] How to bind ESC key to close a `gwindow()` in gWidgets?

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.
