Hi I've got follow code: angular.module("myApp", []).controller("myController", function($scope) { $scope.pressedKey = function(keyObj) { $scope.myKey = keyObj.key; } }); <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div ng-app="myApp" ng-controller="myController"> <input ng-keypress="pressedKey($event)"><br>{{myKey}} </div> I use the ng-keypress on an input for detecting if there was a key-event and which key was clicked. I need all numbers and letters and also the enter and delete key. Now, the numbers, letters and the enter works fine, but

问题 This question already has answers here : Keyboard Input & the Win32 message loop (2 answers) Closed 4 years ago . I am trying to do a very simple task - have an event occur when a key is pressed - but am having a lot of difficulty implementing it. I am using the Win32 API.

Detecting multiple simultaneous keypresses in C#

由 十年热恋 提交于 2019-12-06 10:02:12
I am looking to emulate hyperterminal functionality for my Serial Communication in C# by detecting the keypresses of certain key combinations (escape sequences) which cannot be typed out such as Ctrl+C, Ctrl+Z, etc. I understand that these keys have their ASCII equivalents and can be transmitted as such. But I am facing problems with the detection of multiple keypresses. Some of my code is provided as a reference : private void Transmitted_KeyDown(object sender, KeyEventArgs e) { if (e.Modifiers == Keys.Control || e.Modifiers== Keys.Shift || e.Modifiers==Keys.Alt) { var test = (char)e.KeyValue

I want to append chars to QLineEdit by sending KeyEvent.
