keyboard

问题 I have few "hotkeys" in my application. All "hotkeys" sequences are unique in application scope (so for example F12 key will always fire the same single task). In few places there are handled like here: if (e.Modifiers == Keys.Shift && e.KeyCode == Keys.Delete) { this.Close(); } if (e.Modifiers == Keys.Shift && e.KeyCode == Keys.Up) { if (Program.PerformLogin()) { frmConfigurationSetup frmSetup = new frmConfigurationSetup(); frmSetup.Show(); } } if (e.KeyCode == Keys.F12) { frmAbout formAbout

问题 I have made a page using jquery, and on load it selects the first text field automatically. I want it to then move to the next field when the ENTER key is pressed. $('.barcodeField input').bind('keyup', function(event) { if(event.keyCode==13){ $("this + input").focus(); } }); I can't find anything that works on the net. And I've scoured the forums. 回答1: I've created a little function which can do what you need. This is the version I use so you may need to change the class names but you should

问题 See the attached photo. Twitter does it well. They have a layout, which I will call a toolbar for lack of a better term, right above the onscreen keyboard. How can I do this with my code? UPDATE: Here is my layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#ffffff"> <RelativeLayout android:id="@+id

问题 I am using below code to get the keyboard location from view & add DONE button on it.But in ios 8 it is not able to get keyboard location & hence not add DONE button. UIWindow *tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1]; UIView *keyboard; for (int i = 0; i < [tempWindow.subviews count]; i++) { keyboard = [tempWindow.subviews objectAtIndex:i]; // keyboard view found; add the custom button to it if ([[keyboard description] hasPrefix:@"<UIPeripheralHostView"] ==

问题 System.Diagnostics.Process exposes a StreamWriter named StandardInput, which accepts only characters as far as I know. But I need to send keystrokes as well, and some keystrokes don't map well to characters. What should I do? 回答1: You are mixing input streams with control signals. A console process has a default input stream which you can control with the StandardInput, as you already know. But Ctrl-C and Ctrl-Break are not characters sent to the process through this stream, but instead they

问题 I am continuing to program some kind of keyboard navigation in my simple graphic program (using C#). And I ran into trouble once again. My problem is that I want to process the keyboard input to move a layer around. Moving the layer with the mouse already works quite well, yet the control doesn't get the focus ( neither KeyUp/KeyDown/KeyPress nor GotFocus/LostFocus is triggered for this control ). Since my class derives from Panel (and overwrites a couple of events), I've also overwritten the
