key-bindings

问题 I am using PyQt4 and a QTreeView (although this could just as easily apply to qt directly). Right now there are default key bindings that control the expanding/collapsing of branches using the right and left arrows. Unfortunately, these bindings are not ideal and I would like to disable them. I have not been able to figure out how to do that. Does anyone know how to disable (or reassign) the default key bindings on a QTreeView? 回答1: There are two possible options for you: 1) Reimplement the

问题 Currently, I am using GUD in the newest version of Emacs. The keybinding has changed since the old Emacs. Now it is "\C-x \C-a \C-b" for setting a breakpoint but it was \C-[space]. I was wondering if there is anyway to change the keybinding to the old format? (For some reason I cannot change my Emacs version) I am using Emacs 24.5 Here is my .emacs file: ;; .emacs ;;; uncomment this line to disable loading of "default.el" at startup ;; (setq inhibit-default-init t) ;; turn on font-lock mode

问题 I'm trying to get the path of the current file + the file's name (without extension) in a Key Binding file in Sublime Text 2. $file_path or ${file_path} are both not working. The reason is that I want to execute an *.exe file, which was built before (but don't want to both build and execute in one step). Any ideas? Greetz 回答1: you may try the sublime-snippet, this is my code: #filename: filename.sublime-snippet <snippet> <content><![CDATA[$TM_FILENAME]]></content> <!-- Optional: Tab trigger

问题 Good Day! I am tying to add keyevent listener to jTextField so that if the user pressed the tab key, the caret position will go to the end of the text inside the jtextField, here is my code: private void jTextField1KeyPressed(java.awt.event.KeyEvent evt) { if(evt.getKeyCode()==KeyEvent.VK_TAB){ evt.consume(); jTextField1.setCaretPosition(jTextField1.getText().length()); } } But it doesn't work. How can i make this happen? 回答1: One way is to: First of all, don't use a KeyListener since this is

问题 In my web app I want to use ctrl + alt + c as hotkey. I read bunch of Stack Overflow articles and came up with below solution $(document).keydown(function(e){ if(e.ctrlKey && e.altKey && e.which == 99){ e.preventDefault(); window.prompt("Copy to clipboard: Ctrl+C, Enter", text); } }); This is not working in chrome. I tried debugging. What I noticed is as soon as I press ctrl key it goes into function and as if condition fails it is coming out. How can I get this to work. 回答1: There are two

问题 I've got: (global-set-key '[f11] 'menu-bar-mode) How can I bind it to left ALT / Meta and will there be conflicts of using alt as meta? 回答1: You can't bind a function to a modifier key, because Emacs does not receive any input when a modifier key is pressed on its own (or more accurately, when one or more modifier keys are pressed without a non -modifier key also being pressed). n.b. Your operating system determines which keys are modifiers, not Emacs. You could probably tell your OS not to

问题 I open the dialog from the main window, where by clamping the keys, I fill the line with their names. The problem is that I can not understand where you need to do a cycle of checking all the keys on their state. Maybe there is another way to get the keys pressed? Or where you need to listen to the clamping so that the dialog box does not hang and the string is updated. MainWindow: def showBindings(self, param): from dialogs import KeyBindingsDialog self.dialog = KeyBindingsDialog() self

问题 I want to make a program with these goals: 1) Make a JButton 2) Attach the button to a key (The "A" Key) using KeyBindings 3) Execute some code when "A" is clicked Here is the code I have so far: // Imports Public class Test{ JButton button = new JButton(); //... Test(){ button.getInputMap().put(KeyStroke.getKeyStroke("A"), "Pressed"); //... } // Where do I add the code that responds when button is pressed? } Now where do I add the code that I want it to execute when the button is pressed?

问题 I've read from the GNU getline documentation that it's capable for binding some callback functions to some keys. I know already how to bind an action to the TAB key using rl_bind_key function. But how can I use it to bind some action to the following keys?: CTRL + TAB , ESC , PAUSE / BREAK 回答1: #include <stdio.h> #include <readline/readline.h> int my_cool_readline_func (int count, int key) { printf ("key pressed: %d\n", key); rl_on_new_line (); return 0; } int main(void) { rl_command_func_t

问题 I need to check when the user presses on a key and releases it. If a key is held in, I will do something once. I used the keystroke to get the button I want to relate an action with. I used also a semaphore to overcome this problem but it looks crazy My code: ` InputMap inputMap = jPanel1.getInputMap(); KeyStroke keyPressed = KeyStroke.getKeyStroke(KeyEvent.VK_1, 0, false); KeyStroke keyReleased = KeyStroke.getKeyStroke(KeyEvent.VK_1, 0, true); //------------------------------------------
