onkeydown

We're trying to provide an application to the mentally and physically handicapped daughter of my neighbor that let's her use an Android tablet as a Talker, i.e., she presses a few big buttons and the devices generates speech. The application is basically a WebView and an additional object in Javascript used to perform and control the speech generation, plus some logic to handle the orientation changes. Html files are generated offline for her specific layout of the talking items. We've also added some music playing and picture viewing facilities to make the device more appealing to her.

I would like to create a photo/video capture application. I have created a CaptureView class which extends SurfaceView and placed it in the main form. The main form's activity has onCreateOptionsMenu() method which creates a menu. The menu worked fine but then I tried to implement a method onKeyDown : @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if(event.getAction() == KeyEvent.ACTION_DOWN) { switch(keyCode) { case KeyEvent.KEYCODE_CAMERA: videoPreview.TakePicture(); return true; } } return super.onKeyDown(keyCode, event); } The menu doesn't appear anymore and the method

My extensions go through every input entered on an on any website that is loaded. What I do is I consider every onkeydown and manipulate it if it has some value. my background js file contains the following: document.onkeydown = returnKey; function returnKey(evt) { var evt = (evt) ? evt : ((event) ? event : null); var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null); if ( node.value == 'fi' ) { evt.srcElement.value = "??"; } } My problem is when I have websites that already contains onkeydown function in their innerHTML webpage. for instance: taken from facebook's

I have created a Chrome extension that uses the hotkeys [Alt]+[0...9] only to discover facebook uses the same hotkeys. Is there any way possible my extension could disable facebook's hotkeys so that mine fire alone? I'm fairly certain I have identified the code facebook uses to implement their [Alt]+[0...9] hotkeys: document.documentElement.onkeydown=function(a){a=a||window.event;var b=a.target||a.srcElement;var c=a.keyCode==13&&!a.altKey&&!a.ctrlKey&&!a.metaKey&&!a.shiftKey&&CSS.hasClass... This is in a script called from the head of the root document. I have tried the following to disable

In a WPF application, I have a control that I have derived from TextBox like this: public class SelectableTextBlock : TextBox { protected override void OnKeyDown(KeyEventArgs e) { base.OnKeyDown(e); e.Handled = false; } } The OnKeyDown method is not called when entering a space into the TextBox, nor when hitting Backspace, but does fire for other input including normal printable characters (e.g. 'a') and modifier keys (e.g. ). I'm using this control with IsReadOnly set to true so I can display selectable, uneditable text. The control used within WPFToolkit's DataGrid, and I want KeyDown events

I've just upgraded my app to use the newly released v22.1.0 AppCompat and now onKeyDown and onKeyUp are not triggered when menu key is pressed. The other keys correctly trigger onKeyDown and onKeyUp , but when i press the menu key nothing happens. If I downgrade to v22.0.0 everything returns to work properly. How do I fix it? Update 23 August This has been fixed again in the v23.0.0 of appcompat-v7 support library. Update to the last version to see this fixed. Update 19 July Unfortunately AppCompat v22.2.1 broke the onKeyDown and onKeyUp events again . I just updated

I have a function that is triggered by the onkeydown event of a textbox. How can I tell if the user has hit either the backspace key or the del key? Stephano Try this: document.addEventListener("keydown", KeyCheck); //or however you are calling your method function KeyCheck(event) { var KeyID = event.keyCode; switch(KeyID) { case 8: alert("backspace"); break; case 46: alert("delete"); break; default: break; } } Nowadays, code to do this should look something like: document.getElementById('foo').addEventListener('keydown', function (event) { if (event.keyCode == 8) { console.log('BACKSPACE was
