Populating JTextField based on latest KeyStroke

本小妞迷上赌 提交于 2019-12-02 05:49:04
The use case in my UI is to populate two JTextField components based on double clicking items in a JList . The easy was is to use a JCheckBox populate jTextField1 if the checkbox is selected, and populate the other if it is not selected or vice versa which is working perfectly. But I would like to explore if this can be done without the checkbox. As in, if I type something in jtextfield1 and double click the item in list to complete the text, the item clicked should be appended to jtextfield1 based on fetching the latest KeyStroke I used. Is there are any way to do this? The use case in my UI

Convert String or Char to Keys object

耗尽温柔 提交于 2019-12-02 04:57:48
问题 If I use the following code: for (int i = 0; i < text.Length; i++) { char c = text[i]; Keys k = (Keys)(byte)c; MessageBox.Show(c.ToString() + "|" + k.ToString()); } I can get a correct conversion for uppercase letters only. The problem is, I need to be able to replicate lower case characters as well, and I am getting conversion errors on them. For instance, 'e' converts to 'NumPad5', where 'E' converts correctly to 'E'. How do I attack this? I'm going to be taking input strings and creating

Python code to cause a backspace keystroke?

£可爱£侵袭症+ 提交于 2019-12-01 16:32:43
I keep finding ways to map the backspace key differently, but that's not what I'm after. I'm in a program writing a python code, and basically I want to write a line of code that causes the program to think someone just hit the Backspace key in the GUI (as the backspace key deletes something) How I would code in a backspace key stroke? The character for backspace is '\b' but it sounds like you want to affect the GUI. if your program changes the GUI, then simply delete the last character from the active input field. foo = "abc" foo = foo + "\b" + "xyz" print foo >> abxyz print len(foo) >> 7 if

Preventing “Enter” from submitting form, but allow it on textarea fields (jQuery) [duplicate]

This question already has an answer here: Prevent users from submitting a form by hitting Enter 30 answers $(window).keydown(function(event){ if(event.keyCode == 13) { event.preventDefault(); return false; } }); The above is the code I got which effectively kills the "enter" key as a form submitter throughout the system, which is exactly what I want. However, the enter key is also disabled on textarea tags - which the users should be able to hit enter on in order to go to the next rows. So is there a way to modify the above code to detect IF the enter is coming from within a textarea tag, it

Localized accelerators (JMenuItem hotkeys) in Swing

痴心易碎 提交于 2019-12-01 13:11:15
I am working in an English app on a german laptop, over a spanish OS. Even if I explictly set Locale.setDefault(Locale.ENGLISH) at the beggining of my app, I am seeing the hotkexs in the menu as CTRL + Mayúsculas + C instead of CTRL + SHIFT + C that I passed to the KeyStroke object. Is not only that word does not get localized to english as I specified, but also that it maps SHIFT key to MAYUS (CAPS LOCK in english), so I guess this is not only a language issue, but keymap´s as well. So how can I impose english for all the GUI components? Thank you! You have to make sure that you set the

How to capture global keystrokes with PowerShell?

浪尽此生 提交于 2019-12-01 10:44:59
问题 Can Powershell listen for and capture key presses? Is it possible to write a PowerShell script that, like AutoHotkey, sits in tray and waits until you press a predefined keyboard key to start execution? And possibly not return but fire every time you press said key? What I would like to achieve is - perform a predefined scripted action at the press of a button only AFTER starting the script, so putting it on the desktop and defining a shortcut key doesn't work. For example: I'd like the text

do something once the key is held and repeat when its released and repressed

二次信任 提交于 2019-12-01 09:08:56
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); //------------------------------------------ jPanel1.getActionMap().put("_1000Press", _1000Press); inputMap.put(keyPressed, "_1000Press"); jPanel1

How to set on key press key binding?

不羁岁月 提交于 2019-12-01 07:47:09
问题 The arrow keys for this application need to cause press and release events independent of focus. Setting onKeyRelease true causes a release event as expected but setting onKeyRelease false (code below) doesn't seem to stop auto-repeat. Is there a way to implement the key binding to trigger once when the arrow key is pressed and held? Action right = new AbstractAction() { public void actionPerformed(ActionEvent e) { ... } }; mainPanel.getInputMap(JPanel.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT) .put

Simulate “Windows” key and “+” key to zoom in

北慕城南 提交于 2019-12-01 00:07:36
Windows 7 (finally) has built-in zoom feature for the screen. Hold down the "Windows" key and you can then use the "+" key to zoom in and the "-" key to zoom out. As a result I have been trying to simulate this combination. With AutoIt I have tried: 1) Send("{LWINDOWN}" & "+" & "{LWINUP}") 2) $x = Chr(43) Send("{LWINDOWN}" & $x & "{LWINUP}") 3) Send("#{+}") ;//works but it also sends "+" key 4) Send("{LWINDOWN}") Sleep(10) Send("+",1) Sleep(10) Send("{LWINUP}") None of those 4 steps work... I actually want to use this functionality on c#. If I manage to do it with autoit I could invoke that
