keyboard-events

On my Windows Phone app I need to change my view accordingly to my keyboard. I have several questions: How can I identify that the keyboard is opened? Is there an event on view for keyboard opening? Is there a way to get the height of the keyboard? Or the area size of the blocked UI (by keyboard)? You can access to keyboard information by Windows.UI.ViewManagement.InputPane class. There is static method GetForCurrentView() . It returns InputPane for current view. InputPane has events Hiding and Showing and property OccludedRect which returns region that input pane is covering.

I have this extremely basic example here: http://jsfiddle.net/arhVd/1/ <form> <input type="text"> <input type="submit"> </form> $(function () { $(document).keydown(function(e) { e.preventDefault(); $('form').submit(); }); }); I want to ensure that when pressing F4 it does not do the built in browser function (in F4's case set focus to the URL bar.

Wondering how to link a keyboard key to a JButton in netbeans, Downloaded KeyEventDemo program from oracle that lets you press a key and it tells you the keycode, Now im wondering how to implement that, working on a calculator project and I already have the ability to click on any button and have it either + , - , / , * or enter so now I am wondering how to link the 2 together, essentially I'm trying to figure out how to check which key is being pressed in a method, and then run a method depending on what they pressed! thanks for any info!

In my PreviewKeyDown() handler how do I tell the difference between the ENTER key on number-pad and the ENTER key on the main board? Both keys return the same value Key.Enter for KeyEventArgs.Key . The closest answer I can find to this question is here: What's the difference between Key.Enter and Key.Return? , but unfortunately this works only if the app is fully trusted. I'd like a solution without this restriction. See link , example impl. below. private static bool IsNumpadEnterKey(KeyEventArgs e) { if (e.Key != Key.Enter) return false; // To understand the following UGLY implementation

I'm working on a canvas-based game and am using window.addEventListener() to attach keyup and keydown events globally. This works in when viewing the page normally, but when embedding it as an iframe; it doesn't get the keyup and keydown events. Is there a better way I can do this? You can't, not unless the frame has focus. What you can do is make a keydown on the outer window focus the iframe, or always somehow focus the iframe, or focus the iframe by default (might be good enough, not sure what you're doing) But for the window keydown to fire on any window (frame or not) that frame needs
