用Karabiner来解决Mac上部分软件小键盘不能用的问题

阅读更多关于用Karabiner来解决Mac上部分软件小键盘不能用的问题

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Mac上的大部分软件对外置USB键盘支持都是不错的，但是也有一些软件比较偷懒，比如我最近碰到的一个软件就是根本不支持小键盘输入数字，而用大键盘上的数字键倒是没有问题，实在是奇葩。奇葩归奇葩，问题终究还是要解决的。稍微研究了一下这个问题，发现可以用Karabiner这个软件来对键盘进行映射。对于我的需求，就是把小键盘上的数字键映射成大键盘上的数字键。实现起来不怎么难，先上我修改的private.xml文件内容吧： <?xml version="1.0"?> <root> <item> <name>Change KeyPad 0 to Num 0</name> <identifier>private.change_keypad0_to_num0</identifier> <autogen>__KeyToKey__ KeyCode::KEYPAD_0, KeyCode::KEY_0</autogen> </item> <item> <name>Change KeyPad 1 to Num 1</name> <identifier>private.change_keypad1_to_num1</identifier> <autogen>__KeyToKey__ KeyCode::KEYPAD_1, KeyCode:

问题 I'm writing a program in Linux which reads and distinguish inputs from two USB devices(two barcode readers) which simulates a keyboard. I've already can read inputs from USB, but it happens before OS translate keycode in a charactere. For example, when I read 'a' i got 24, 'b' 25, etc.... For example, when I read 'a' i got 4, 'b' 5, etc.... Is there any way to convert that code in a char without manual mapping? Some output exemples: KEYPRESS = a output = array('B', [0, 0, 4, 0, 0, 0, 0, 0])

问题 I'm trying to use the Robot class in Java and type some text. Unfortunately I'm having problems finding the key codes of the square brackets, this symbol | and this symbol `.

Thanks in advance. 回答1: It's in the JavaDoc for KeyEvent KeyEvent.VK_OPEN_BRACKET and KeyEvent.VK_CLOSE_BRACKET Edit From the KeyEvent JavaDoc This low-level

Catch “Command+R” in Safari with JQuery

阅读更多关于 Catch “Command+R” in Safari with JQuery

问题 I need to intercept the browser-reload-functionality in Safari (I know this is usually not something one should do, but in my case this makes sense). For Windows I just do this: $(document).keydown(function(event) { if ( event.which == 116 ) { restart(); return false; } }); Do I need to use a JQuery Plugin to capture two Keys at the same time or is this already implemented in JQuery in some form? Also, are the keycodes under Mac the same as they are under windows? ("Command" being the keycode

阅读更多关于 Is this the proper behaviour for event filter and requstfocus in javafx?

问题 I have a very simple task to accomplish. I just want to press any letter on a button, matches the key code, and move the focus to a text field. I wrote a simple test code as shown. I have no problem to shift the focus. However, I don't want the letter I press shows up in the text field. Seemingly a simple programming solution turns out to be not so simple. I don't understand why the event consume method doesn't stop the event from propagating down the event chain and have the typed letter
