Handling keyboard events in python

由 点点圈 提交于 2019-12-02 16:40:18
问题 How can I handle keyboard events in python? More exactly I need to manage keyboard arrows and some other keys for my command-line application. Is there a module for this or I need to handle key by key using for example "if get(key)==(mykey): do something" (it's pseudo-code)? I'm on Gnu/Linux OS. 回答1: You're probably looking for a python (n)curses library. This will allow to "get around" your terminal buffering and work with key-presses directly. 回答2: Would the cmd module suit your needs? It

How to handle several keys pressed at the same time in Kivy?

问题 I was planning on doing a little crossplatform game with kivy and, when I was testing the way to get input from the keyboard on the pc, I had a little surprise. Kivy doesn't seem to handle several keys pressed at same with it's on_keyboard_down events, when you press more than one key at same in kivy, the keyboard class used in the official documentation passes the last pressed key in change of all the keys being pressed at the moment. It looks like the keyboard class is designed to let the

While Navigate User from Alphabets Keyboard to Symbols Keyboard, Layout Alignment gets spoiled. By Default, Layout takes 5dp padding & User can't see the Last Column Keys. Note: Images shown in below. I handled Key Actions to Navigate User from Alphabets Keyboard to Symbol Keyboard in the onKey Method override fun onKey(primaryCode: Int, keyCodes: IntArray?) { when (primaryCode) { KEYCODE_ALPHABETS -> { keyboardView?.keyboard = Keyboard(this, R.xml.keyboard) } KEYCODE_SYMBOLS_1 -> { keyboardView?.keyboard = Keyboard(this, R.xml.keyboard_symbols_1) } KEYCODE_SYMBOLS_2 -> { keyboardView?

Sending keyboard events programmatically doesn't dispatch them into inputs

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-02 10:16:16
问题 I am sending programmatically generated keyboard events to the document. I was hoping that the currently focused input element would display them, however it doesn't. The events are generated from a string with this function: const simulateKeyPress = keys => { keys.split('').forEach(theKey => { const e = new window.KeyboardEvent('keypress', { bubbles: true, key: theKey, keyCode: theKey.charCodeAt(0), charCode: theKey.charCodeAt(0), }) document.dispatchEvent(e) }) } If I add an EventListener

I'm trying to follow this StackOverflow article, referring to this similar article on StackOverflow, and this from the UWP Windows Dev Center.

C# Actively detect Lock keys

由 眉间皱痕 提交于 2019-12-02 08:25:26
问题 I have a wireless keyboard and mouse that doesn't have any lock indicators, nor any software bundled to provide a visual aid, so I'm making my own. I got it so that if I click on a notifyIcon it'll list which lock(s) are turned on, but I'd like to make it smarter by alerting me once the locks are engaged. I found a few items online, but honestly I just want the lock keys, I don't care about any other keyboard presses. I'm using C# .NET 4, though I can use .NET 4.5 if there's something with

JavaFX weird (Key)EventBehavior

由 坚强是说给别人听的谎言 提交于 2019-12-02 06:54:33
问题 So I have been experimenting with it a litle bit with javaFX and I came across some rather weird behavior which might be linked to the TableView#edit() method. I'll post a working example on the bottom of this post again, so you can see what exactually is happening on which cell (debuging included!). I'll try to explain all the behavior myself, though its way easier to see it for yourself. Basically the events are messed up when using the TableView#edit() method. 1: If you are using the
