How can we give the option to edit the cell value of a table to user

i have a Jtable which shows the entered values of all the expenses daily.Before saving them i want to provide an option to user for editing.How this is possible.
I went through the TableCellEditor interface .I think it needs to be implemented some code there.
help me out in implementing those methods.

Might I suggest reading the JTable tutorial? And/Or perhaps purchasing a book on swing?

  • How can I get all options under edit in iPhoto to appear and revert in red, the only option it gives me is to select multiple

    how can I get all options under edit in iPhoto on my phone to appear it has revert in red on theleft side & done on the right side, the only choice it gives me is select multiple

    The usual cause of that issue is a corrupted or missing font that Firefox replaces by another, in this case a bold, font.
    As a test you can try to disable the default font and choose a few different fonts (Arial, Verdana, Tahoma, Times New Roman) to see if you can identify the culprit.<br />
    you will have to reinstall that corrupted font.

  • Design option missing for Fluid Grid layouts (was:In dreamweaver CC, I created a new fluid grid page, but the options to edit the page...)

    Hi, in dreamweaver CC, I created a new fluid grid page, but the options to edit the page are limited to code / split / live. The design optin is missing and I need it to move around the fluid grid to position my elements that I have created.
    Thanks

    Hi Raymi,
    Like Ben suggested, you can vote for the feature using the link provided.  From what I understand, the product team is collecting feedback on the limitations of Live View for FG layouts and improving experience on that front. It would help if you could provide a list of limitations with the current workflow.
    Thanks,

  • Right clicking the star of an already bookmarked site does NOT bring up the option to edit the bookmark to put it into a chosen location as described in Helpl

    The option to edit the bookmarks is missing from my current version 29.0.1. Right clicking the star
    produces a menu but not the one described in Help.
    Move to Menu
    Remove from Toolbar
    Menu Bar
    Bookmarks Toolbar
    Customize

    This question was about clicking the star on the Navigation Toolbar to edit the bookmark.
    You need the left-click the highlighted star button to edit the bookmark because a right-click opens the toolbar context menu.
    You can right-click a bookmark in other places like on the Bookmarks Toolbar or in the sidebar and in the Bookmarks Manager (Library) to edit the Properties.

  • How can two people on different computers edit the same video

    I am working on a large project and need more than one person editing. How can I allow 2 or more people edit the movie we are working on. I have two windows 7 working on a network in CS6

    I'm sure large organisations benefit from larger discounts than I can find online, but at first glance it seems to me that Adobe Anywhere is going to need around $60K investment in hardware (windows 8 enterprise servers, Tesla K10 GPUs and media grid) before you even get a look at what Adobe will ask for in terms of Anywhere licenses, or how plugins etc will work (or not).
    And that's a minimum entry level system, clearly the big guys are going to spend a LOT more than this.
    Adobe Anywhere is (as I suspected when it was first announced) going to be out or reach for most people looking to share projects between a couple of remote editors, though I'm sure for some smaller companies it could easily pay for itself in reduced facilities costs over time.
    I guess we'll just have to continue the way we are for now... though frankly the repeated "conforming" is beyond a joke.  I still can't figure out why Premiere Pro seems to randomly decide it needs to reconform all the media so that I have multiple copies of the conformed files with incremental numbers after them and have to wait 2 hours for some multicam sequences to be even mildly editable because one of it's files is last in line to be done.   So we end up transcoding everything to a 32bit float audio which totally undermines the concept of editing natively. < sigh >  FCPX doens't need to do this, so why does Premiere Pro?

    Hi, Yanesh:
    Please understand, the FrameMaker feature known as a run-in paragraph, which is a paragraph with a "carriage return" but without a "line feed," HAS NO COUNTERPART in InDesign. InDesign also lacks the FrameMaker side heading feature, which is created by the combination of a reserved area in the text frame and the paragraph property to inhabit that area. FrameMaker separates paragraphs by using the larger of space below paragraph and space above paragraph, but InDesign separates paragraphs by adding the space below paragraph and the space above paragraph.
    There are several complicated manual methods of simulating these FrameMaker properties in InDesign.
    Here's a recent forum discussion of these exact issues: http://forums.adobe.com/message/3759635#3759635. The thread mentions DTP Tools' conversion tool, the MIF Filter commercial plug-in for InDesign, and discusses its shortcomings. I don't recall it mentioning in-tools.com plug-ins that can simulate side headings, like those in FrameMaker, but they don't convert FrameMaker to InDesign. 
    You can add your vote for InDesign's developers to include these FrameMaker features, and any others you'd like to see, here: wish.

  • When downloading, all screens are lists except last. It is a dropdown menu. How can I see all options and not the dropdown?

    My computer just crashed. On the new machine, as well as my laptop, when I save a file, I see icons on all screens except the last. The last option is a drop down menu and if my choice is more than 6 or so choices down, I have to scroll down. On the previous desktop, I saw icons listing the final choices.

    HA!  I figured the find my iphone out!!!!! You can have more than one icloud account in "Mail, Contacts and Calendars".  So my husband's & kids' phone icloud account under "settings, icloud "is their individual @me.com account.  Set it to everything you want EXCEPT Find My Iphone.  Then under "settings, mail/contacts/calendars" you set up both accounts (your @me.com which may already be there), then add another with the main appleID and enable ONLY Find My Iphone.  Now when any of us log into Find My Iphone from any device with our main apple ID for the app store, all the devices show up!!!! YIPPEE.  I made my own day!
    I think the message I got previously was because I hadn't disabled the find my iphone on the @me.com account first.

  • How can i give 2 different names for the same attribute in querypannelVC

    Hi
    I have a View criteria and exposing as a query panel.In the VC, we are using one VO attribute instance twice"FullName".We have a requirement of display 2 different names for this attribute in the query panel Ui.Attached the VC screenshot.
    Ex:Present in the Query panel Ui fields are displaying like
    FullName
    FullName
    Requirement:
    Owner
    Assignee
    Thanks in Advance,

    Hi Thanks for the reply..So are you saying like add the same "FullName" attribute twice with different Alias Names(Owner,Assignee) ?But here we are having the FullName as common and depends upon role we are displaying "Owner" or "Assignee".If i create two instances for same attribute will it not be like redundancy ?

  • How can I add a character globally to empty cells in an InDesign table?

    I have a document with 190 tables, each with many empty cells. Client now wants m-dashes in the empty cells. Is it possible to do this in an automated fashion, without having to go cell-by-cell?

    Hi Jarek,
    Unfortunately I'm still getting the same "no tables found in the active document" message after modifying it the way you instructed.
    Here's my current code. Hopefully you'll be able to detect my problem. I greatly apologize for my ineptitude in javascript
    try 
    var myCells = app.app.selection[0].cells.everyItem().getElements(); 
    alert("myCells:" + myCells.length) 
    for(i=0; i<myCells.length; i++) 
        if(myCells[i].contents == "") 
            myCells[i].contents = "N/A" 
    catch(myError) 
        alert("no tables found in the active document") 

  • In Flash CS4,How can I give a AS3 List Component a suitable horizontalScrollBar

    In Flash CS4 when an AS3 List Component has too many rows,it will has a verticalScrollBar automatically. but it will never has a horizontalScrollBar even a part of the content of the list is hidden.
    I set the property  list.horizontalScrollPolicy="on",and set list.maxHorizontalScrollPosition=200; then the horizontalScrollBar appear
    but when I click the item of the list, all the list move to left, half of the list is hidden,
    I can only see the right part of the list, the I click the list again,the list move to right,then I can see all the list by move the horizontalScrollBar
    How can I give a suitable horizontalBar to the AS3 list component?

    Thank you for your help! (sorry,I`m bad in English...)
    In fact, it works.
    but,I made a mistake,the reason I want to give a list a horizontalScrollBar is:I want to show all content in a list that is not wide enough,
    you see,first row can show all content in this list,but in the other rows,the content is too wide to show,I want to give the list a horizontalScrollBar to show all content by draging the horizontalScrollBar to right.
    now,set property:
    list.horizontalScrollPolicy="on", list.maxHorizontalScrollPosition=30;(the result is the image above),when I drag the horizontalScrollBar to right:
    ah ha ,the row can`t show all content too,the horizontalScrollBar is related to the width of all the list, is not related to the width of the content in every row.
    now I kown why the horizontalScrollBar is always disable.
    but in design,to show a lot of content,we can`t draw  a list too wide, it`s not beatiful,so I want to use a horizontalScrollBar to show all content in every row.
    and the list is not too wide
    ah ah,  like the list in Flex4
    In fact,ah,I have not studied Flex 4,so,I have to make it by using Flash CS4 Component
    How can I do? Please
    (so sorry for my bad English,I do my best in it)

    IPAD2 users, how do I crop/drag profile pictures in Facebook?  Facebook gives me the option to drag the picture but it just can't be done.

    Well thank you for your honesty.  Apple requires you have to have a Mac to develop iPhone apps, ergo my foray into OS-Xland. No way around it that one except for running OSX in a VM, which would have probably saved me some quid, true enough.
    BUT for those interested parties: VirtualBox has a startup script in /Library/StartupItems/VirtualBox that will prevent OSX from fully booting on the initial (and required) rEFIt boot cycle. Once I temporarily moved that out of the StartupItems rEFIt went in as expected.
    FYI, the openSUSE desktop running native is a little peppier than OSX native which was a nice surprise.  Now if the Mac just had more open source software we would have a deal. (:

    To Reset Your Security Questions, You will need to call Apple (0800 048 0408) and Reset them, you'll need for verification access to the apple id web page (myappleid.apple.com) and it will ask for a temporary pin and also a iDevice on hand to recieve a code from Apple in order to reset your security questions

  • My user account on my MacBook Pro isn't giving me the option of 'edit picture'. How can I solve this problem?

    So basically, I recently got a MacBook Pro, and the first thing I did when I got it, was set up my user account. However, I soon noticed that the only options for a user account icon were icons that my MacBook came with (flowers, footballs, piano etc.) or if I took a picture with my webcam. I know that I'm supposed to have an option of selecting a picture from my iPhoto library etc. but my mac isn't letting me do that. It's not giving me the option of 'edit picture' which I know directs you to your photo library.
    <---- see, the 'edit' button doesn't highlight unless I click on a picture.
    I'd appreciate it if someone could help.... thanks a lot!

    You don't have to do it that way. All you need do is click on the image then click on this icon:
    This is the Edit symbol, apparently.

  • How can I give an user the right to change passwords

    I'm still absolute server beginner, so I have to ask here.
    How can I give users the right to change passwords or to view calendars?
    I didn't find it, yet.
    I've found an option to change rights, when I click on the user with two fingers (right mouse button). But all options in this menue are grey.

    Hi Holger,
    These are two fundamentally different issues. I'll try to address them each. For both you will need to have OpenDirectory set up (see the Users Next Steps list in the Server app). Once that is done. Additionally you will need the Server Admin Tools 10.7. Once you have them installed, you can specify the OpenDirectory password requirements for users
    User Passwords in OpenDirectory
    On the server, open Server Admin app.
    Connect to you server, then click on the OpenDirectory service.
    Click on the Settings icon.
    Click on the Policies tab.
    Click on the Passwords sub-tab, and you can set all the criteria for password requirements here.
    Resetting Passwords
    Users must log in as network users on the client computer.
    Once logged in, to change the password, open System Preferences.
    Click on Users & Groups.
    The user icon will be a silhouette with stars in the background. This means it is a network user. Click on the Password tab at the top.
    Click the Change Password ... button to change the password.
    Calendars in iCal are much like RSS feeds: users need to subscribe to them, like we discussed in our other posting. Network users will automatically be given a network iCal calendar, and will be automatically subscribed to it. However, if you want to automatically add subscribed calendars to network user's accounts, you will need to use ProfileManager.
    On the server, open Server app.
    Click on the Profile Manager menu item.
    Make sure that iCal service is running (green indicator next to it). Click on the "Include configuration for services: ...". Make sure the iCal icon is listed there.
    Click the "Sign configuration profiles" checkbox.
    Turn Profile Manager on.
    Once Profile Manager has loaded (the gear at the bottom right will no longer be spinning), go ahead and click the Open Profile Manager link.
    Log into Profile Manager as your directory admin user.
    Click on the Groups menu item to give all users of a specific group access to the wiki calendar. This is best if you have a wiki for a group and want to share that calendar. Use the Everyone group to add this calendar for all users.
    Click on Users to give access to only specific users.
    Edit the profile for the group(s) or user(s) you selected by highlighting that group and clicking the edit button.
    Scroll down and select the CalDav item on the left.
    Click configure. Here you will need to enter the specific details for that callendar based on the subscription details you get when subscribing to the calendar via the wiki.
    After all that you still need to configure each client computer to be set up for profile management, which really is a topic of its own. I recommend the following tutorials:
    Installing OS X Lion Server
    OS X Lion Server Administration Tool Tour
    Setting Up Profile Manager on OS X Lion Server
    Using Profile Manager on OS X Lion Server
    Hope this helps, good luck!
