keyboard-shortcuts

问题 I was working on a project, and while pressing some shortcut keys, I noticed the status bar of Visual Studio 2010: Please try some shortcuts yourself to notice the whole behavior of VS, and then...how could I achieve that effect at the same level of performance? Thanks in advance! P.S. I have the following code block taken from Stack Overlow, that does something like that but not the same performacnce level. My code works for CTRL + K , P . protected override bool ProcessCmdKey( ref Message

问题 I override ProcessCmdKey() in my MDI parent form class and have some keyboard shortcut calling method in same class. But I wish to make these hotkeys working in parent/child form and other form. The case now is when focus on the other form(regular form, not MDI), ProcessCmdKey() doesn't capture keyboard anymore. Which class should I put ProcessCmdKey() in and anything to make it work? Thanks! namespace myNamespace { public class MDIParent : System.Windows.Forms.Form { public bool NextTab(){..

问题 I have code that let my users open the File Browser of the client's browser so they can select a file. That works fine when the user clicks a button with the mouse, but somehow it completely fails with the keyboard. So I setup the button as follow: var that = this, upload_button = jQuery(".upload-button"); upload_button.click(function(e) { e.preventDefault(); e.stopPropagation(); // simulate a click on the hidden file-input button that.upload(editor_widget); }); I setup the keyboard as follow

问题 I'm trying to hook up a keyboard shortcut for my chrome extension. I'm using a jQuery plugin for this: http://oscargodson.com/labs/jkey/. Here's the code I'm using to test it out: $(document).ready(function() { function say_hello() { alert("hello!"); } $(document).jkey('/', say_hello); }); I have this in my background page right now, but it doesn't work. Is this type of code something that should go in the background page, or something that's more appropriate for a content script? Or should I

问题 In Eclipse there is the nicest feature, when you hover with the mouse over an Open or Close element (Any Open or close bracket ' ( ', ' { ', ' [ ', ' ] ', ' } ', ' ) ', the Quotation Mark ' " ' or the tag ' ' ') and you double click the mouse, Eclipse conveniently selects the content from the opening to the closing (or vise verse, depends on the element you hover over) of the element without selecting the elements. I love this feature, I love it so much and it would be a great disappointment

问题 How do I configure keyboard shortcuts to click specific buttons in a PyQT app? Eg: Ctrl + 1 to click one button while Ctrl + 2 to click the other? 回答1: Use QtGui.QShortcut: you build it with a QKeySequence , and it emits the activated() signal when that key sequence is typed while the shortcut's parent widget has focus (of course, you connect those signals to slots of your choosing, including buttons'). 来源： https://stackoverflow.com/questions/2039241/pyqt-shortcut-to-trigger-a-button

问题 I'd like to map a command in emacs to a key-binding. I want the command Control-l to have the same effect as the command Alt-x goto-line followed by a return (since that command first needs a return to be invoked and then a line number). I modified the init file as follows: (define-key (M-x goto-line) '\C-l) but that didn't work. The error was that define-key was being given more than 1 arguments. Does anyone know how to reset key-bindings in emacs? Thanks! 回答1: M-g g is the default shortcut

问题 I have a simple winforms application in VB.NET 2008. I am using a form with a completely custom look, so there is no title bar, thus no minimize, maximize, and close buttons. I've created custom controls to replace those. If I have my app running, and I click the 'Show Desktop' shortcut, all the programs minimize properly, including mine. But, if I use the Windows + M shortcut, all the programs EXCEPT mine minimize. It seems that the lack of the built-in minimize button on the form causes my

问题 The Run > Debug History menu item in Eclipse (Helios) contains a MRU list of debug history. These items are numbered from 1 to N suggesting that there is probably some keyboard shortcut or keyboard sequence I should be able to enter to relaunch a previous program but I cannot figure out what they might be. Specifically, if I want to relaunch the debug history item number 2, what must I type to use this feature? I know that there is the Window > Preference > General > Key settings page which

问题 For a rich web application, I need keyboard shortcuts. Because there are many different keyboard layouts, they have to be configurable. Unfortunately, I can't figure out a way to map keyboard events to human-readable shortcut names such as Ctrl + Alt + Y or Alt + \ . The keypress event is useless since it doesn't fire for all keys. Here are some properties of keydown events: charCode : Works only for printable characters. Deprecated , according to MDN code : Works, but ignores the keyboard
