key-bindings

问题 I'm using this code to bind keyboard keys to custom actions without using the KeyListener : Action left = new AbstractAction() { @Override public void actionPerformed(ActionEvent e) { System.out.println("pressed left key"); } }; Action right = new AbstractAction() { @Override public void actionPerformed(ActionEvent e) { System.out.println("pressed right key"); } }; Action space = new AbstractAction() { @Override public void actionPerformed(ActionEvent e) { System.out.println("pressed space

问题 I'm making a multiplayer platformer/shooter/brawl game with pygame and I'd like for the players to easily change their keybinds (such as from a config file). I haven't been able to find a way to read a character string and use that as a transition to the pygame.K_xx objects as of now so I ask the community. Any leads ? 回答1: With the constants of this list you can use getattr(pygame, 'K_'+ mychar) to access a constant by name. 来源： https://stackoverflow.com/questions/46714719/pygame-get-key

问题 I'm trying to key bind the a and d keys to make a character move left and right, but the actions only happen once when you press the keys. How can I modify this code to make it do the event while a or d is being held down? p.getInputMap(JPanel.WHEN_IN_FOCUSED_WINDOW).put(KeyStroke.getKeyStroke(KeyEvent.VK_W, 0),"up"); p.getActionMap().put("up", new UpAction()); p.getInputMap(JPanel.WHEN_IN_FOCUSED_WINDOW).put(KeyStroke.getKeyStroke(KeyEvent.VK_A, 0), "left"); p.getActionMap().put("left", new

问题 What's the key-binding for Control-Shift-Tab? I've tried lots of things and nothing seems to work. I'm already aware of tkinter.ttk.Notebook.enable_traversal. If you know of a handler for tabs being activated, that would suffice, too. 回答1: The general format for representing an event is: <[event modifier(s)-]...event type [-event detail]>. For key-binding Ctrl+Shift+Tab the format would be: 'Control-Shift-KeyPress-Tab'. In this case the event modifiers would be: Control- Shift-, the event

问题 When I trying to use default keymaps like Ctrl-C, Ctrl-V, etc. they not working. When I trying to map custom keymap, I get error by pressing on character keys: Unknown keyCode: 0x0 What it can be? I tried to install Java 1.6, 1.7, same thing. PS: Using Fedora 19 EDIT My default lang is English. But playing with keyboard settings of XFCE made it work oO. Issue with keyboard layouts.. Thanks 回答1: What's your primary keyboard layout. Make sure it's English and not Russian. Try adding -Dide.non

问题 What is the simplest way to (globally) bind a key combination (e.g. <Super>+A ) to a function in a gnome shell extension? Inspecting a couple of extensions, I ran into the following code: global.display.add_keybinding('random-name', new Gio.Settings({schema: 'org.gnome.shell.keybindings'}), Meta.KeyBindingFlags.NONE, function() { /* ... some code */ }); I understand that the key combination is specified by the schema parameter, and that it's possible to create an XML file describing the

问题 Here is what I've got so far.. I'm using this as a keybind. I want to press the "Down" arrow key anytime the app is running, and then make it auto press the "Down" arrow key 3 extra times then finish by pressing "Enter" in the code. I know this isn't the best explanation but sorry and I will try to explain it any better if you still didnt understand. Here is the code: public class MyKeyListener extends KeyAdapter{ @Override public void keyPressed(KeyEvent evt){ } KeyListener keyListener = new

问题 I'm an Emacs user looking into Sublime Text 2. I've remapped the default Emacs key bindings and have become accustomed to moving about using Alt+i, Alt+k, Alt+j, Alt+l for up, down, left and right. I haven't had any issues remapping those keys in Sublime Text. The problem is that whenever I use these keys to navigate the menu pops up even though I've hidden it in distraction free mode. I would like to stop the menu coming up when I press the Alt key. If possible I would like to remap the key

问题 The same question has been asked for Xcode 3 But the solution there is said to not work with Xcode4. And no new solution is available there. How to get a key-binding to move the curser up/down about 10 lines in Xcode 4 ? 回答1: Eureka! Inspired by the answer on line duplication, this is how you empower Xcode 4 with multiple-line movement: Go to the folder /Applications/Xcode.app/Contents/Frameworks/IDEKit.framework/Versions/A/Resources Open IDETextKeyBindingSet.plist . Add a new dictionary
