keyboard-shortcuts

问题 I have written an SWT UI which has a primary function of displaying text in a StyledText control. I want to add a handler for Ctrl + F so that when that shortcut is pressed the focus is set to a search box. I have tried using the following code to detect the keypress. sWindow = new Shell(); ... sWindow.getDisplay().addFilter(SWT.KeyDown, new Listener() { @Override public void handleEvent(Event e) { System.out.println("Filter-ctrl: " + SWT.CTRL); System.out.println("Filter-mask: " + e

问题 After testing a lot I can't record if Alt key is pressed using GetAsyncKeyState in a C program. When I try this: if (GetAsyncKeyState(VK_SHIFT)) // do something It works properly, but when I try this if (GetAsyncKeyState(VK_MENU)) // do something It doesn't work. So my question is "How I can record ALT?". Thanks in advance 回答1: I use the code below to find out the value of any key that perfectly fits in GetAsyncKeyState , I think it is 18 for ALT key . #include <iostream> #include <cstdio>

问题 In VisualStudio .net (say 2005) I have this shortcut Alt + Ctrl + F4 which closes all the opened windows. (Already mapped to window.closealldocuments) and another one Alt + Ctrl + Shift + F4 to close all but this window. Now both shortcuts used to work on my previous workstation.

问题 I've been have difficulty with KeyListener (not detecting keys) and I'm trying to switch over to KeyBindings but JFrame doesn't extend JComponent which is needed for the getInputMap() function. Any ideas? 回答1: Use a surrogate JComponent instead. For example, set the frame's contentPane to be a JPanel and use it to register the key bindings. This is a very basic example, which uses a JPanel as the contentPane and adds a Canvas to it. The key bindings are then registered through the JPanel on

问题 My text editor contains two textAreas (TA). TA1 is for input Devanagari Unicode texts and TA2 is for output in ASCII as transliterated texts which get printed simultaneously as the input text got typed key by key using DocumentListener. I do this using a one to one transliteration scheme. However there are cases I need to map multiple/two Devanagari UCodes input in a single ASCII character. Eg. क्=k (क्=क+्). The problem is here that a single two UCodes containing character is generated

问题 For me, Visual Studio's Ctrl + K , Ctrl + C keyboard shortcut is used to comment-out the selected lines. When editing C++, this sometimes uses block comments ( /* */ ) and sometimes uses line comments ( // ). Why does it change?

Based on my own tinkerings, and what was said in
