key-bindings

问题 I am trying to make key bindings in Java on a JPanel. I want a certain action to execute when I press the 'w' button. I follow the Java tutorial on making bindings, but the actionPerformed method does not execute (i.e. no text prints out). The following is the entirety of the code for my test GUI, with the relevant part highlighted: import java.awt.BorderLayout; import java.awt.event.ActionEvent; import javax.swing.AbstractAction; import javax.swing.JFrame; import javax.swing.JPanel; import

问题 I'd like to bind Ctrl + R to 'isearch-backward and bind Ctrl + Shift + R to 'tags-apropos but I can't distinguish between the two key presses. Can emacs differentiate between Ctrl + R and Ctrl + Shift + R ? What should go into my .emacs file to allow this keybinding? 回答1: Yes. (global-set-key (kbd "C-r") 'isearch-backward) (global-set-key (kbd "C-S-r") 'tags-apropos) The way to figure out the answer to this kind of question is to do help on a key C-h k , and type the keystrokes you're

问题 I'm embedding a JFileChooser in my program in my own frame with other custom components in the frame. Here's a design of my app as it may help visualize my issues: If you can't tell, the lists directly under the JFrame titles are JFileChoosers . The way this is supposed to work is you assign shortcuts to destinations and then when you press those shortcut keys, the selected file moves to the destination. My strategy for doing this is to assign the shortcut to a javax.swing.JComponent.WHEN_IN

问题 I would like to map: CAPS-LOCK to Fn Fn to Left-MOUSE LSHIFT + 3 to # RSHIFT + 3 to something else etc. I have searched exhaustively for any tool that offers complete freedom for remapping keyboard input, but cannot find one. (Windows has AutoHotkey). I'm planning to write my own tool that parses a config file. But how to actually dig in and do this? Solving this problem will require a thorough understanding of the journey of a keystroke through the operating system, so as to intercept at the

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . I need to bind all the arrow keys to perform the same function but each time get which key was pressed. Currently I only have when the right arrow key is pressed via the following DoneImg.getInputMap(JLabel.WHEN

问题 I can't find anything that looks like this online. I am looking for a way to create a collection of Keybindings in the code (with a Keybinding ViewModel), and then bind the collection to the view, instead of listing out every binding manually in Xaml. I would expect it to look something like this <Window.InputBindings ItemsSource="{Binding Path=KeybindingList}" /> and then in the code, have a List. Is such an approach possible? Where would I start? 回答1: You can create an attached property,

问题 Okay, I did a mistake and blindly copied and pasted a ''code snippet' that is supposed to restrict the user from typing down ANYTHING ELSE other than a number in a Bootstrap input field. By blindly doing that, i did not really understood how it's supposed to work. Now i need to allow the decimal point, the "." to be typed down and i don't know what i need to change. Can someone explain the snippet below or provide a resource? $('#elementXPosition,#elementYPosition,#elementWidth,#elementHeight

问题 so this is my very first post and i am really sorry if my grammar is bad (english is not my mother language). I recently started programming in java and i am interested in learning. So i started a few small projects to help me understand more of the basic stuff and to improve my coding. Recently i read about keyListeners, keyBindings and all that stuff. So i thought i code a very basic program (nearly no gui) which should work like a simple piano: import javax.sound.sampled.AudioSystem;

问题 I am attempting to have a key binding cause an event within the view model. I have been search for a while and have not come across any solutions that have worked thus far, unfortunately. This is what I am basically attempting to implement: <i:Interaction.Triggers> <i:EventTrigger EventName="createNew"> <cal:ActionMessage MethodName="newCustomer" /> </i:EventTrigger> </i:Interaction.Triggers> I am wanting a way to provide a "hotkey" to allow the user to implement a newCustomer event within

问题 I use urxvt (terminal) under awesome (window manager) and ubuntu (os). In graphical mode, c- set the mark but in text mode it inserts a space. The problem is solved when using gnome-terminal but some other key combinations still does not work. For instance, C-: insert a : in both terminals. I do not know where to look at to correct this behaviour. C-h k (help on key combination) followed by one of these combination shows only the key pressed along ctrl, for instance C- is interpreted as . As
