Alexey, > Does the input map of JTextArea contain shortcuts for Cut, Copy and Paste? When I call (on my Mac, using openJDK 17) UIManager.getDefaults().get("TextArea.focusInputMap”) … I get an InputMap with: “copy-to-clipboard”, “cut-to-clipboard”, and “paste-from-clipboard”. The code I tested against is: InputMap inputMap = (InputMap) UIManager.getDefaults().get("TextArea.focusInputMap"); Map<Object, Collection<KeyStroke>> map = new TreeMap<>(); for (KeyStroke keyStroke : inputMap.keys()) { Object key = inputMap.get(keyStroke); Collection value = map.get(key); if (value == null) { value = new HashSet(); map.put(key, value); } value.add(keyStroke); } for (Map.Entry<Object, Collection<KeyStroke>> e : map.entrySet()) { System.out.println(e); } Previous tests showed the same naming convention on Windows for JTextFields; I don’t know how standardized that naming convention is across all platforms / L&F’s. - Jeremy ------ Original Message ------ From mark.yagnatin...@barclays.com<mailto:mark.yagnatin...@barclays.com> To alexey.iva...@oracle.com<mailto:alexey.iva...@oracle.com>; micklen...@gmail.com<mailto:micklen...@gmail.com>; client-libs-dev@openjdk.org<mailto:client-libs-dev@openjdk.org> Date 3/5/24, 11:48:48 AM Subject RE: how to get find out the keyboard shortcut for the paste action?

Hello Mark, As far as I know, the shortcuts are localisable. For example, you use Ctrl+S to save a file in an English version, yet users of Spanish version of Windows use Ctrl+G (for Guardar) instead. At the same time, the most common actions — Cut, Copy and Paste as well as Undo and Redo — usually have the same shortcuts across all languages and OS, although macOS uses Cmd instead of Ctrl. However, the shortcut for Redo is not as standard, Ctrl+Shift+Z and Ctrl+Y are used, both could be mapped at the same time. I wonder what is the shortcut for Undo in German versions since German keyboard layout has Z and Y keys swapped. Does anyone know? So, the shortcuts used in an application are controlled by the application and the shortcuts can be localised. For this reason, the shortcuts are usually “hardcoded”. @Jeremy Does the input map of JTextArea contain shortcuts for Cut, Copy and Paste?

If you’re wondering how my curiosity got piqued initially, it was something like this: A while ago, someone at work was adding copy/paste support to some component that didn’t have it. I noticed that they “hardcoded” the shortcut “ctrl C”. And I thought to myself: Swing already “knows” that this is the right keyboard shortcut, in the sense that all components that support copy/paste “out of the box” use it. It would be nice if there was some way to ASK it to tell me what it “knows”. *From:* Jeremy Wood <micklen...@gmail.com<mailto:micklen...@gmail.com>> *Sent:* Sunday, March 3, 2024 11:30 PM *To:* Yagnatinsky, Mark : Markets Pre Trade <mark.yagnatin...@barclays.com<mailto:mark.yagnatin...@barclays.com>>; client-libs-dev@openjdk.org<mailto:client-libs-dev@openjdk.org> *Subject:* Re[2]: how to get find out the keyboard shortcut for the paste action?

Hmm. Good question. Not that I know of. > Again, one could create a scratch text area and grovel through its input map, but that seems hacky. I agree sifting through the L&F seems hacky. I don’t think I understand exactly what you’re trying to implement here. If you give me a more concrete example: maybe I (or someone on this list) can offer a more concrete suggestion? I’ll add some context in case this speaks to your question. By default Swing gets this information in places like BasicTextUI#getInputMap(), which calls: InputMap shared= (InputMap)DefaultLookup./get/(editor, this, getPropertyPrefix() + ".focusInputMap”); The following works on my Mac & Windows machine (I think using JDK 19), but I wouldn’t be surprised if it fails in other platforms / L&F’s. It feels brittle, but it might (?) have potential: private KeyStroke getCopyKeyStroke() { InputMap inputMap = (InputMap) UIManager.getDefaults().get("TextField.focusInputMap"); for (KeyStroke keyStroke : inputMap.keys()) { Object action = inputMap.get(keyStroke); if ("copy-to-clipboard".equals(action)) { return keyStroke; } } /// this will show all the default keystrokes // System.out.println(Arrays.asList(inputMap.allKeys())); /return null; } Regards, - Jeremy ------ Original Message ------ From mark.yagnatin...@barclays.com<mailto:mark.yagnatin...@barclays.com> To micklen...@gmail.com<mailto:micklen...@gmail.com>; client-libs-dev@openjdk.org<mailto:client-libs-dev@openjdk.org> Date 3/3/24, 6:00:46 PM Subject RE: how to get find out the keyboard shortcut for the paste action? Thanks for the response! I didn’t expect to get one at this point J It does indeed answer my question! (Though you didn’t quite get the name right: there’s no Ex at the end… I take it you’ve done some Windows programming at some point) But now I have a new question… Is there any way to get the “usual” letter for a “common” operation? For instance, lots of programs support copy and paste. Is there a way to ask Java “what is the standard letter for paste” and get back “V”? Again, one could create a scratch text area and grovel through its input map, but that seems hacky. -- Regards, Alexey This message is for information purposes only.
