keyevent

问题 On my Samsung Galaxy tab 4 (Android 4.4.2, Chrome: 49.0.2623.105) I ran into a situation where the keyCode is always 229. I've setup a simple test for two situation <div contenteditable="true"></div> <input> <span id="keycode"></span> script: $('div, input').on('keydown', function (e) { $('#keycode').html(e.keyCode); }); DEMO Fortunately I can find posts about this, but I couldn't find one with a working solution. Someone suggested to use keyup instead or to use the textInput event, but that

问题 I'm a little confused over how key events (back key, volume keys) relate to Views in android.

问题 localRobot.keyPress(KeyEvent.VK_F); I have no clue how to make this keypress an uppercase keypress. I attempted to press VK_SHIFT and release afterwards, however that didn't work. Would it work to press the capslock button? If so, how do I do it? Is it just VK_CAPS? 回答1: I believe this might work. It presses the shift button, presses yours then releases. localrobot.keyPress (KeyEvent.VK_SHIFT); localrobot.keyPress (keyCode); //Your keycode(your letter) localrobot.keyRelease (KeyEvent.VK_SHIFT

问题 Ok, so I'm trying to Unit test some GUI elements I have a JButton with text of "Create" and the mnemonic set on 'C' or code 67. I can write a unit test that I can call the .doClick function on and assert that what that button is supposed to do, happens. However, I now want to write a unit test to test that the mnemonic portion of that same button works identically to the button click. I've searched on and off for a couple of days now and have tried many things. I've tried using Robot from the

问题 Hi hope someone can tell me what I am doing wrong with my Key Event. I am using a Card Layout to navigate through two of my JPanels atm. To do so I use Action Events as well as Key Events. The action events will toggle between JPanels when a button is pressed while the key events will hide away the buttons when a key is pressed. All good with the key events, it does what I want (call a method on one of the panels to set the bounds of the buttons placed inside it eq: button.setBounds(-1, -1,
