keyboard

问题 I have a Unity UI's input field and a text box. When I use Input.GetKeyDown ( KeyCode.Return ), it only works on the OS X and PC build and not on the iOS build. iOS keyboard's Return key does nothing. I have tried the events, too, but it doesn't work even then. Somebody please tell me the solution to this problem if there is any? 回答1: While I can't think of a way to harness the return key directly on iOS, there is a way to do so with the "Submit" key using the TouchScreenKeyboard class in

问题 I am using the below code to pass special keys using SendInput . I am facing one strange issue. If user sends any of Alt / Ctrl / Shift , the key remains pressed e.g. if user passes Alt + F4 , the code runs properly and action is completed successfully but Alt key remains pressed. I need to manually click Alt key after the operation is completed. Please let me know to handle the same in the code itself. Below is the code used to send special keys. namespace RemoteDesktopSendKeys { class

问题 I am having a weird issue with my keyboard automatically closing and then reopening when I open multiple UIAlertViews. If I have a keyboard (from a separate UITextField) and I display a UIAlertView, then upon dismissal of that alert I open another (opening the second one in the didDismissWithButtonIndex). When I dismiss the 2nd one it dismisses the keyboard which then comes back up. If i try this with more than 2 alerts in a row, it will still close my keyboard after the 2nd alert is

问题 I'm having a code with a loop asking for some input and then sleeps for some time. The purpose is to prevent for human errors, forcing the user to wait before entering the next input. The problem is, that python does not ignore the keyboard inputs while time.sleep. Here is an example code: from time import sleep from msvcrt import getch for i in range(3): print 'Enter a character' char = getch() sleep(2) print char When pressing some characters consecutively during time.sleep(), msvcrt.getch(

问题 For the challenge and educational gain, i am currently trying to make a simple game in the console window . I use a very primitive "locked" framerate system as such: using System.Threading; // ... static private void Main(string[] args) { AutoResetEvent autoEvent = new AutoResetEvent(false); Timer timer = new Timer(Update); timer.Change(0, GameSpeed); autoEvent.WaitOne(); } So, a timer ticks every GameSpeed miliseconds, and calls the method Update() . The way that i have understood input in

问题 I have made an application in Delphi that handles some defined system wide hotkeys, works perfectly. However, for some hotkey functionality I have to trigger/simulate some keyboard strokes such as ALT+ENTER. This works great when the user releases the hotkey keys directly, but when the keys are still pressed by the user the keyboard simulation fail. Is there a way (with windows API) to check if all keys are released before I process a keyboard simulation? 回答1: Use GetAsyncKeyState as this API

问题 I have a View that overrides the OnKeyDown event. I can get the Key Code and the KeyEvent, but it seems that I'm missing something. Let me explain. For non-US keyboard layouts, the Key Code I'm getting is wrong. For example, when I press the ñ key in my Spanish keyboard , I expect to receive a "ñ" letter, but instead I get a Keycode.AltLeft as Key Code. How do I get the real letter? Another problematic case is with accentuated characters: When I press the ´ key and the o key, I shouldn't

问题 Based on the link scrollviewer to scroll to textbox position I tried to resolve scrolling issue when keyboard is launched but there is a problem in landscape mode. Problem in using (App.Current as App).RootFrame.RenderTransform = new CompositeTransform(); in landscape mode. Above solution helped me to generate a behaviour similar to New Appointment page as in the default calendar app for windows phone 7.5. But this (App.Current as App).RootFrame.RenderTransform = new CompositeTransform();does

问题 (I posted this before anonymously, but then couldn't use the same computer again, so I'm posting it from my account now. Sorry to the guy who answered before.) I'm working on an iPhone app which involves typing stuff into a UITextView, which adds content to a UITableView. The problem is, I need to be able to close the keyboard when the user's done with it, and the only area that is really visible other than the keyboard and UITextView at this point is the UITableView. I'm having trouble

问题 I have this function where #text_comment is the ID of a textarea: $('#text_comment').live('keypress',function (e) { if(e.keyCode == 13) { textbox = $(this); text_value = $(textbox).val(); if(text_value.length > 0) { $(this).prev().append('<div id="user_commenst">'+text_value+'</div>'); $(textbox).val(""); } } }); What is happening is the text is appending when the enter/return key is hit (keyCode 13), but it is also moving the text a line down, as the enter/return key is supposed to. This is
