editing

问题 I'm using view-based NSTableView and would like to allow users to edit text in place. Cocoa typically has superb support for this, but I am not sure how to bind the value of NSTextField to one string while displaying a slightly different string to the user, as shown below. For example, when user clicks on a text field or presses enter key to edit, the field editor should only be filled with exportTest.zip and not exportTest.zip Shared , and whatever edit user makes should only affect the

问题 first of all an Happy New Year to all :) I have found that it's possible modify the editing menu (copy/paste/select etc) thanks to the UIMenuController menuItems. I'd like to have a link to my app from other apps through this editing menu, for example a "copy to my app" menu item. Obviously, I can't modify the code of other apps, but is there a way that nears to this? 回答1: It's called "cloud computing". This is, where you have a web service you send the data to, and then in your other app, on

问题 How do i cut,copy,paste from main menu in a multi textboxes form ? How does the menu knows to apply on the active textbox ? 回答1: Please see this article here on Codeproject that does the job in synchronizing each text box's "standard" edit menu such as Copy, Cut, Paste, Undo, Select All. Of course, the code originally targets the .NET 1.1, but it can be easily recompiled to target the newer frameworks as well. 回答2: In the menu click event you can examine this.ActiveControl to see what control

问题 my goal is to move text in a PDF around, which is within a certain rectangular area. There is an existing Item on stackoverflow, which already got me close to achiving this: iText or iTextSharp rudimentary text edit However, I would be back at manipulating the PDF on a very basic level. Is there a chance to use higher level facilities of itext to alter the position of the text? I'm afraid there is no simple solution, but I'd be happy to get some suggestions. PS: Also keep in mind that I want

问题 Every time I use find-file in Aquamacs or Emacs, it auto shows the previous directory, for example ~/Work/abc/cdf. However, if I want to open something from the ~ directory, I have to press Delete all the ways down to the first character. Is there any quick way to replace all the string with just one or two keys? Thank you in advance. 回答1: Yes, while still in the mini buffer press Ctrl-A to go to the start of the file name path, and Ctrl-K to delete it to the end of the line, now your file

问题 We are aware of how to allow users to edit multiple jqGrid rows - but how would one have a single save button that saved all edited rows? 回答1: We do it manually (not with a jqGrid feature). We have a custom formatter which draws editors and we put a <form> tag around the whole grid, with a submit button at the bottom. 来源： https://stackoverflow.com/questions/3738778/jqgrid-how-to-edit-and-save-multiple-rows-at-once

问题 If I set the caret on a line and accidentally press Ctrl X or Ctrl C instead of Ctrl S , then the entire line is cut/copied, since there is no selection. This can be very annoying, and can often times destroy code in the clipboard which I wanted to paste. I'd expect nothing to happen if nothing is selected. How can this be turned off? 回答1: Go to Registry screen: Help | Find Action... and search for registry there Once there -- find and activate editor.skip.copy.and.cut.for.empty.selection

问题 I am doing a program in VHDL to read and write data. My program has to read data from a line, process it, and then save the new value in the old position. My code is somewhat like: WRITE_FILE: process (CLK) variable VEC_LINE : line; file VEC_FILE : text is out "results"; begin if CLK='0' then write (VEC_LINE, OUT_DATA); writeline (VEC_FILE, VEC_LINE); end if; end process WRITE_FILE; If I want to read line 15, how can I specify that? Then I want to clear line 15 and have to write a new data

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I need to edit an Excel workbook using python. Is there a way of doing this without reading in the workbook, editing what I want and the writing it back? i.e. is there a way I can do this on the fly, as I only need to edit a couple of values per sheet? I have looked at pyexcelerator , xlrd , and xlwt , but they
