cursor-position

问题 I'm trying to put together a game for Mac OS X which involves a lot of fast action and flinging around of the mouse cursor. If the user wants to play in windowed mode, I'd quite like to lock the cursor to the inside of the window to avoid accidentally changing programs in the heat of battle (obviously this will cancel itself if the user changes programs or hits escape for the pause menu.) On Windows, this can be accomplished easily with ClipCursor(). I can't find an equivalent on Mac OS X. Is

问题 ...how would you do it? task for extra credit: figure out a way to force vim to refresh the cursor position immediately after exiting insert mode 回答1: Although I would not recommend changing default cursor mechanics, one way of achieving the behavior in question is to use the following Insert-mode mapping. :inoremap <silent> <Esc> <Esc>`^ Here the Esc key is overloaded in Insert mode to additionally run the ``^` command which moves the cursor to the position where it was the last time Insert

问题 The old version of the question is below, after researching more, I decided to rephrase the question. The problem as before is, I need to focus a contenteditable div without highlighting the text, doing straight up focus highlights the text in Chrome. I realize that people solved this problems in textareas by resetting the caret position in the textarea. How can I do that with a contenteditable element? All the plugins I've tried only works with textareas. Thanks. Old Phrasing of the question

问题 This question already has answers here : Get cursor position (in characters) within a text Input field (8 answers) Closed 5 years ago . Is there any way in jQuery to get the current cursor-position in an text input without doing ugly browser specific code? Like in: <input id="myTextInput" type="text" value="some text" > the cursor being after the "x" of "some text", I can get "8"? 回答1: You can't do this without some browser specific code, since they implement text select ranged slightly

问题 This could be very simple. I have a textbox on a WinForm, Text = "ABCDEFGH". I need to select "BCD" and leave the I-Beam (cursor, caret, blinking '|') right between the 'A' and the 'B'. Setting SelectionStart = 1 and SelectionLenght = 3 doesn't work and I can't figure it out. 回答1: You need to set the SelectionLength to 0 as noted in the documentation. You can programmatically move the caret within the text box by setting the SelectionStart to the position within the text box where you want

问题 I want to have an insert tab button for my UITextView so that users be able to insert a tab at beginning of the current line. No matter where the cursor is in the line, the tab should be inserted at the beginning of the line, and after that the cursor must go to the end of the line. Is it possible ? 回答1: I have no luck with positionFromPosition:inDirection:offset: and characterRangeByExtendingPosition:inDirection: . But this works fine for me: UITextRange *range = [textView selectedTextRange]

问题 I am working (joyfully) working through the Introduction to Emacs Lisp Programming and have solved the first 8.7 Searching Exercise. It states, Write an interactive function that searches for a string. If the search finds the string, leave point after it and display a message that says “Found!”. My solution is (defun test-search (string) "Searches for STRING in document. Displays message 'Found!' or 'Not found...'" (interactive "sEnter search word: ") (save-excursion (beginning-of-buffer)

问题 When the Summernote text editor initializes with the focus property set to true , the editor gains focus but places the cursor at the beginning of the editor. My preference would be to have the cursor placed where the user had clicked initially. At a bare minimum I would just need to place the cursor at the end of the editor. The Summernote API doesn't seem to directly support this and I've tried various hacky looking solutions; Such as emptying the text area, creating the editor, then
