由 半腔热情 提交于 2019-12-09 21:41:49
问题 When I switch to Russian layout in Windows 7 and press ; key on the keyboard, I get Russian letter ж on the screen.

jQuery - using arrow keys to navigate grid of divs

由 你。 提交于 2019-12-09 19:08:17
问题 I'm pretty new to HTML, CSS and jQuery - and while my HTML and CSS are OK, my jQuery is not too good - and I think I'm trying to achieve something quite complicated. As you can see in the code I have a calendar built, and I want people to be able to navigate around it using their arrow keys and press enter to highlight a square. The best example of what I want is this http://jsfiddle.net/BNrBX/ but it VERY confusing! As the html has noting but the container div, and I'm not good enough at

How to detect keyboard events on hardware keyboard on iPhone (iOS)

由 孤街浪徒 提交于 2019-12-09 19:05:10
问题 I have an app with a login page that has three fields for three different random characters. When the user leaves the last field, the soft keyboard disappears and the user can touch a "login" button on screen. When there is a hardware keyboard (bluetooth or physical) attached, I'd like to be able to hit "enter" on it. However because the user is not in a field, I can't see how to detect this key being pressed. Would anyone have advice on which class handles key press events? Presumably there

How to get in python the key pressed without press enter?

问题 I saw here a solution, but i don't want wait until the key is pressed. I want to get the last key pressed. 回答1: The related question may help you, as @S.Lott mentioned: Detect in python which keys are pressed I am writting in, though to give yu advice: don't worry about that. What kind of program are you trying to produce? Programas running on a terminal usually don't have an interface in which getting "live" keystrokes is interesting. Not nowadays. For programs running in the terminal, you

Getting correct character on keyboard event

由 人盡茶涼 提交于 2019-12-08 16:33:35
问题 I am making a little word game where I need to get the last char that users enters on their keyboards. I figured two ways to do this. First one is to get each char by listening on document keyboard event and getting it by keycode. It worked very well until I started writing chars with keyboard dead keys (like Ā). String.fromCharCode(e.keyCode) translates it to A as the keyCode is for the A, but there seems to be nothing on the event regarding dead key or real char that the event produced.

Keyboard input as Unicode characters in python

由 耗尽温柔 提交于 2019-12-08 11:00:08
问题 I want to detect keystrokes in python code. I already try a lot of methods with different libraries but all of them cant detect the UTF keyboard input and only detect Ascii. For example, I want to detect Unicode characters like ("د") or ("ۼ") if a user typed these keys. It means that if I press Alt+Shift it changes my input to another language which uses Unicode characters and I want to detect them. IMPORTANT: I need Windows version. It must detect keystrokes even not focusing on the terminal

how do I observe keyboard input event while the applicaion is not actived

问题 how do I observe keyboard input event while the applicaion is not actived. 回答1: You'll need to create a CGEventTap using Quartz Event Services. The user must have access for assistive devices turned on, which makes sense, because that's the only legitimate reason for you to do that. If you want to set up a hotkey, there's an API in Carbon Event Manager for that, and a Cocoa wrapper named SGHotKeysLib. Note that the Carbon Event Manager hotkey API is still supported in current, 64-bit Mac OS X
