问题 The documentation for KeyStroke.getKeystroke(String) (e.g., getKeyStroke("control DELETE") ) does not provide an example of how to access the macintosh command key, and I can't find a reference that lists the spellings of the various words for modifiers like "control" that this function accepts. What is the syntax for the command key? For reference, here's the documentation for getKeystroke: Parses a string and returns a KeyStroke . The string must have the following syntax: <modifiers>* (

问题 I have a main form with two child modeless forms, e.g. all of the forms can be active simultaneously: class MainForm : Form { Form child1; Form child2; public MainForm() { Text = "MainForm"; child1 = new Form { Text = "Child1" }; child2 = new Form { Text = "Child2" }; child1.Show(this); child2.Show(this); } } I would like to allow the user to Alt+Tab into all of them, but surprisingly, I found that if any of the child forms is active, the owner form cannot be selected from the Alt+Tab menu.

问题 In our WPF application, we were wondering why our CTRL-Backslash keyboard shortcut wasn't firing. Wrote a quick test app to log what key was being pressed, and in the OnKeyDown override, e.Key was being reported as OemQuote and not OemBackslash as expected. Worse, on someone else's machine (but also with a US keyboard and the US layout too, but a different manufacturer), they get a different value for e.Key altogether. Yes, I know that's what 'Oem' stands for, but shouldn't all OEMs know what

问题 I was using Resharper and I wanted to try CodeRush so I suspended Resharper and installed CodeRush Xpress. When I installed CodeRush version 2010.1.4 (from this downlad page) the shortcuts did not work. I tried F2 and other shortcuts that schold work but they did not. However I was able to invoke some CodeRush functions by clicking right mouse button and choosing "Refractor" from the drop down menu. When I choose it there is CodeRush action menu where I can select for example "Rename" but as

问题 I have a low-level key logger that receives scan codes, without QKeyEvent's since the QApplication doesn't have focus. The scan codes can be converted into key syms using system specific library calls. Scan codes correspond to Qt's QKeyEvent->nativeScanCode() and key syms correspond to QKeyEvent->nativeVirtualKey(), but Qt's Qt::Key values seems independently mapped. I would like to either take a given Qt::Key and convert to either sym key or scan code, or construct a Qt::Key out of a sym key

问题 Currently i am using "Ctrl + Space" shortcut to fire a JButton event in my Java code like this : this.getRootPane().registerKeyboardAction( addStudentButtonActionListener, KeyStroke.getKeyStroke( KeyEvent.VK_SPACE, KeyEvent.CTRL_MASK ), JComponent.WHEN_IN_FOCUSED_WINDOW ); But i want to assign a shortcut of "Shift + Ctrl + Space" for this event instead. How can i do that ? 回答1: Then use the following key stroke: KeyStroke.getKeyStroke(KeyEvent.VK_SPACE, KeyEvent.SHIFT_MASK | KeyEvent.CTRL

问题 I'm building an app in Angular and I'd like to have keypress events. However, I'd prefer not to litter my code with a keypress here and a keypress there, but rather to put all keypress events into a single factory (or service) and then import this factory into my controllers to use. I HOPE that doing things this way will make it easier for me to manage the keypress events and make sure I don't have conflicts (two events tied to the same keypresses) or something like that. Does anybody have

问题 as soon as i use display.grab_keyboard, no other window seems to know of its own focus. with the keyboardgrab running i can select other windows and even send keyevents to them, but if this window is a text input there will be no blinking cursor. i read something about grab_keyboard generating focusevents, but that doesnt mean it blocks all focus events, does it? what am i not getting here? from Xlib import X,XK from Xlib.display import Display import signal,sys root = None display = None def

问题 Desired behavior : When a Tabkey press happens on a particular dom element in a webPage I want my cursor focus to go to address bar. (I want it via Javascript. Using any browser extension is not what is desired here) When you press Control + L shortcut in a webpage, it takes your focus to address bar. But when I try to trigger this via javascript it does'not work. <div id="1" tabindex="1"></div> <div id="2" tabindex="1"></div> <div id="3" tabindex="1"></div> <script> var some = $('#1'); some

问题 In order to block ALL keyboard access, mouse access and keyboard shortcut events in one of my projects, I: Created a full screen transparent borderless window, in front of other windows, but invisible. Handle all keyboard and mouse events with simple return; the window itself. Make the window modal [NSApp runModalForWindow:myWindow] in order to block keyboard shortcuts. Release window from touchpad's gesture events only. But this guy made it look simple in a tiny app -MACIFIER: How did he do
