Is there a way to retain the focus of an expanded node in ADF Tree?

Hi! All,
We have a requirement that the tree nodes should be expanded and collapsed(traversed,in a word), not only by mouse clicks but also using Keys(Tab+Enter keys).
This is working fine with ADF Tree, but the problem I'm facing is that the tree node that was expanded using keys is losing focus(though the node that is expanded using mouse click is retaining focus).
Is there a way to programmatically access the node that is expanded and retain focus on that node, even if the node expansion is done through Key event rather than mouse event?
awaiting your suggestions,
Thanks and Regards,
Samba

There are some tricky ways to adjust settings within a template (see: this) I think an easier solution is to make 3 or four templates that cover the range you are likely to encounter.  Like a 2 second, 3 second, 5 second, etc... duration template. Label them appropriately and hand over that template toolset to your colleague.

  • Is there a way to retain the original date after editing?

    I am using PSE 11 on a MacBook Pro, OS X (10.3). I have a lot of old pictures to edit, and they are in date order, which is how I want them.
    However, when I edit a picture and save it, it moves it to the bottom, with today's date instead of the original date.  I have them set to save with the original as a version set.
    Is there any way to retain the orignal dates, short of having to go in and reset the date on every picture after I save it?  I really want them to be in date order under their original dates.
    BTW, I used earlier versions that were Windows-based, and this didn't happen.  When I saved them, the version sets stayed where they were.
    This is really frustrating!

    I'd like an answer to this too.
    What's your problem exactly?
    The 'date taken' is never changed by editing a picture.

  • Is there a way to retain the track changes from a Microsoft Word document when working on a IPAD word processing App?

    I am going on a work trip and want to be able to collaborate with my colleagues, almost all of whom will be using Microsoft Word on Microsoft Windows laptops and I want to draft and collaborate on documents.  The approach we always take to such collaboration is to use the track changes feature in Microsoft Word that shows changes and who made the changes.As best I could tell apples Pages software ignores the notations added by the track changes features and accepts all changes to the document making it difficult to see what changes were made and by whom.
    I would appreciate any suggestions to address this challenge.

    I noted from some similar topics that Pages seems to support track changes but that while it reflects deletions made in Microsoft Word, it does not appear to show them -- is there a way to fix this problem?

  • Is there any way to retain the formatting of text being imported from Excell as datasource?

    My client has given me text formatted with italics, bold and colors. I have all the data for my app in an Excel spreadsheet. In Excel, the text formatting is preserved. However, when I import the data into my Siena app, all of the text formatting reverts
    to whatever the format of the label control. Is there another type of control I can use to preserve the rich text formatting?

    Hi Robingo,
    Excel is strictly treated as a data source and Siena only imports the data in your tables, not the formatting.
    If there is some business logic behind the formatting, you could mimic the same logic in Siena. For example, the font is bold or red if a value is in a certain range, the font is in italics if the data is for a specific customer, etc.
    Thanks

  • I have moved itunes library to external drive as per support article. Every time I know open itunes I have to re-direct it to the new media location on the external drive. Is there a way to retain the location?

    I followed the instructions on the support website exactly to transfer my media to an external hard drive (a network attached storage device), it worked immediately. When I quit itunes and re-open it, the library location has reset to the old location, I can change it to the new location and it works but the next time I log in its back to the wrong place.
    Has anybody got any idea how to prevent this from re-occurring?

    i also just move my library to a NAS. i suggest you do this:
    launch iTunes and point iTunes media folder location to the volume/shared folder on NAS. quit iTunes.
    copy the iTunes folder from <MacintoshHD>/users/<yourname>/music to the NAS.
    launch iTunes while holding option (⌥) and click on choose library when prompted. select the iTunes folder you just moved to the NAS.
    you must make sure the volume/shared folder on the NAS is mounted on your desktop before launching iTunes but from now on the media folder location should stick (it does for me).

  • Is there a way to keep the ADL open when testing CS5.5 Air apps after it loses focus?

    When I test Air applications (specifically targeting mobile) it seems that when the ADL (Air Debug Launcher) launches, it will automatically terminate the session when I click on anything else other than the ADL window.  I have been trying to use 3rd party application debuggers that provide improved memory diagnostics, but these debuggers only seem to be able to work when the application is launched through the Flash Player and not through the ADL.  Unfortunately, the Air specific code will only work in the ADL.  Is there some way to keep the ADL running even when it loses focus?  I have tried using the ADL from the Flash CS5.5 IDE as well as from the command line and both will terminate upon losing focus.

    - Transfer the app to the computer by:
    iTunes Store: Transferring purchases from your iPhone, iPad, or iPod to a computer
    - Connect the iPod to the computer and make a backup by right-clicking on the iPod under Devices in iTunes and selecting Back Up.
    - Restore the iPod from that backup. That should also update the iPod.

  • Is there a way to put the cursor at a specific location in a RichTextBox?

    Is there a way to put the cursor at a specific location in a RichTextBox?
    The following code places the cursor at the start of a RichTextBox:
        RichTextBox RTbx
        RTbx.Focus();
        TextPointer tp = RTbx.CaretPosition;
        tp = tp.DocumentStart;
        RTbx.CaretPosition = tp;
    Not sure how to place it at a specific location other than start and end.
    The RichTextBox has contents.  At this point in the code, I do know the specific "word" in the contents, as well as the position (number of chars) where that word is located.  I just need to programmatically place the cursor at that location.

    Oh sorry, I see I missed something out my original reply.
    I have markup:
    <Grid>
    <RichTextBox Name="rtb">
    <FlowDocument>
    <Paragraph >This is the first paragraph</Paragraph>
    <Paragraph >TSecond paragraph is here</Paragraph>
    </FlowDocument>
    </RichTextBox>
    </Grid>
    Code - this is the window contentrendered event
    private void Window_ContentRendered(object sender, EventArgs e)
    rtb.Focus();
    // TextPointer moveTo = rtb.CaretPosition.GetNextInsertionPosition(LogicalDirection.Forward);
    TextPointer moveTo = rtb.CaretPosition.GetPositionAtOffset(9, LogicalDirection.Forward);
    if (moveTo != null)
    rtb.CaretPosition = moveTo;
    I see the cursor between the t and he of the second "the".
    Note that there are numerous other options such as the commented out line.
    Hope that helps.

  • Is there any way to change the default font for outgoing text-messages, in "Messages"? (OSX 10.10)

    Is there any way to change the default font for outgoing text-messages, in "Messages"?
    I can change it for one conversation, but then it resets to the default, tiny font.
    The preferences menu only lets me change the conversation font.
    (OSX 10.10)

    Hi,
    As you may remember there used to be a Messages pane to the Preferences where the Font and colour of the Balloons or background and the Font text colour could be changed.
    And there was a Format Menu for character, word and Sentence changes in the current IM or iMessage.
    Those have gone in Yosemite's version of Messages (Despite it retaining the designation of Messages 8 the same as Mavericks' version).
    All that can be done now is set the size of the font and this has been moved to the General Section of the Preferences.
    The Yosemite version has also been fixed to using the Balloons style of send and receiving any type of messages as well.
    Changing the Font would involved editing the Balloon.transcript file.

  • Is there a way to swap the Fn key and left Ctrl key

    Is there a way to swap the functions of Fn key and left Ctrl key on the keyboard. I'm used to other keyboards where the keys are switched and I keep pressing Fn when I want to press Ctrl.  I figure I'll get used to it eventually, but when I use the laptop in a docking station with a regular keyboard the control key is in one spot and undocked with the Lenovo keyboard the function key is there instead, which makes it hard to get used to.
    If not is there a way to disable the Fn + Space bar function that changes the screen resolution. The programs I use use control + space heavily and my screen resolution keeps changing when I don't want it to.
    It's a small thing I know, but very maddening.

    Thanks, I took the survey. It's interesting the questions on there were asking about location of keys like page up and page down. I find the position of those keys are not that important to me because I don't use them that much and don't seem to mind looking at the keyboard to find them. Also they are almost always in different spots depending on whether you are on a desktop or laptop keyboard so I guess I'm used to unconsciously switching depending on which keyboard I'm on.
    But the left control key is one of the most heavily used, at least by developers like me (control+c to copy, control+v to paste, and control+space for code assist, shift + control + f to format code, shift + control + r to find resources, etc...). I have to hit that Ctrl button 1000 times a day. And the key is in the bottom far left corner on every keyboard (desk top and laptop) I've ever seen until now. Having to remember to look down at the keyboard to find the key is proving difficult and I think is actually hurting my productivity. Especially control+space (when you are expecting a popup to automatically complete the line of code you're working on and instead the screen blinks, resizes and your whole editor loses focus it really breaks your flow of thought, so thanks a million for helping me turn off the silly screen zoom feature).
    Hopefully I'll get used to it like with the other keys like page up and page down although I've had the laptop for two weeks and it's proving difficult. If I had know that Thinkpads have this layout and how maddening it would be to get used to it I probably wouldn't have bought it, even though everything else about it is great. It's amazing how such a small thing can become such an irritant.
    Well thanks again, and if anybody from Lenovo engineering is reading this post, my vote is for some bios setting on the T61P that swaps the functions of Fn and Left control key. It would save me a lot of grief anyway.

  • Is there a way to get the version of the C++ coherence library

    Hi,
    I've noticed that the API for the PofExtractor class has changed from 3.5.1 to 3.5.2. It does break binary compatibility so I need a way to know if I'm loading the right dll.
    Is there a way to get the version of the C++ coherence library? I've been unable to find a "getVersion" like function in the C++ headers...

    Hi Serge,
    It sounds like you are looking for a way to do this at runtime, which unfortunately we do not have. We do have an existing enhancement request (COH-2399) to add this support, but it is currently not available.
    You can check the library version externally in a few ways however:
    - run "sanka -version", using the sanka.exe tool shipped with coherence, it will print out the version string of the coherence DLL it loads
    - use the standard UNIX "what" command supplying it the shared library, and it will do the same, even on Windows
    You could in fact write your own version of 'what' in a function and then do things programatically. Here is the description from the 'what' man page.
    what reads each file name and searches for sequences of the form
    ``@(#)'', as inserted by the source code control system. It prints the
    remainder of the string following this marker, up to a null character,
    newline, double quote, or ``> character.''
    So basically scan the library binary for the pattern and you'll find the version string.
    Regarding PofExtractor, it was unfortunate we had to break backwards compatibility, it is not something we do often, or take lightly. Please note that we did it in such a way to still retain on the wire compatibility, so if that is the reason for your question you should be able to simply not worry about it.
    thanks,

  • I create a birthday calendar in iCal and then click on it in iphoto at the begining of the calendar project each year.  Some how the birthday did not populate the photo calendar.  Is there a way to add the birthday iCal calendar into the calendar project?

    I created a birthday calendar to use in iphoto for calendar.  When a new calendar project is started each year, I click on it in.  Some how the birthday did not populate the photo calendar this year.  The photo calendar is almost complete.  Is there a way to add the birthday iCal calendar into the calendar project? I would prefer not to start over.

    Hi,
    If you first select the calendar on the left, so that its background is highlighted blue/grey, when you make a new events they should be added to that calendar.

  • Is there a way to adjust the settings on launchpad so that when I swipe into it all the open apps/pages are fully separated (like in exposé) so that I can fully view all of them simultaneously?

    Hi Apple community,
    This is my first go at this so be kind,
    My question concerns launchpad. Coming from Snow Leopard I had been using spaces. I like to keep certain bundles of programs on separate desktops, for example all word processing related tasks in one place. I have set up the equivalent on Yosemite.
    My problem is concerns the loss of exposé. Now I know when you swipe into launch pad you get a very similar effect but the issue I am having concerns the "zoom out" effect when you swipe into launchpad. With exposé all open apps/pages etc would be fully exposed - in my case several (sometimes as many as 9 word documents). What I am running into is when I do this in / into launch pad the "pile" of docs is exposed but they are still overlapping so I can't get a good look at which is which and visually identify where I want to navigate to.
    My question is this; Is there a way to adjust the settings on launchpad so that when I swipe into it all the open apps/pages are fully separated (like in exposé) so that I can fully view all of them simultaneously? If so, instructions on how to do so would be greatly appreciated. Any alternative suggestions to doing this outside of launchpad are also welcome. If there is an exposé app for example, I would be quite willing to go that route.
    My main concern is being able to quickly (ie a touchpad gesture) expand all the open pages so I can bounce between them.
    Much thanks from a loyal Apple friend.

    Hey Eric,
    Thanks for taking the time. Unfortunately no that does not solve it. Same as swipe it will get me there and it will show separate programs spaced out. The issue I am having is that all my open word files are bunched up in a pile on top of each other. I can see the edges of each one but I want them to be separated from each other enough that I can visually identify what file is what.
    Again, thanks for trying, it is appreciated.

  • Is there a way of stopping the battery from charging?

    Dear Apple Community,
    Recently I installed iStat Menus and found that, over the course of this year, my Macbook's charging capacity has dropped 5%. I know this isn't a massive number, but battery performance has become a concern for me. I use my Macbook as a desktop replacement, on the main. It's sitting on a mStand, connected to a large monitor on my desk. I use my Macbook to play games, surf the internet, do work and all that good stuff - basically, I use it for everything. I rarely use the Macbook without it being plugged in. I read on the Apple website that they do not recommend leaving the Macbook on charge permanently and that I should use it on battery at least one a month. As I use my Macbook as a desktop replacement, I don't actually have a lot of opportunity to do this.
    My question to you, the community, is: is there a way of stopping the battery from charging, either with the use of an app or a physical device? Ideally, I would love to have my power plugged in BUT only used when the battery drops below 10%. Is this possible with an app?
    On the other hand, am I just worrying about nothing? Will my battery be damaged further if I leave the Macbook charging permanently?
    Thanks for your help!
    Jeremy Reid

    Ideally, I would love to have my power plugged in BUT only used when the battery drops below 10%. Is this possible with an app?
    The charging characteristics are handled in firmware.  There is no app that would be able to do this.  You actually would not want to do this anyway.  Regularly discharging your battery to 10% will greatly decrease the life of your battery.  While it is true that you should not use your system exclusively plugged in, allowing it to run on battery a few hours a week should be fine.  Letting the battery regularly run down to (or below) 10% will cause you to use up cycles more quickly than is necessary (thereby reducing the life of your battery).  It's really a only a matter of disconnecting your Magsafe connector once in a while.
    Leaving it plugged in does not result in it being charged "permanently".  It will charge until it is full and then charging will stop.  It will only begin recharging when it reaches about 95%.
