JTree - Simulate that control key is down.

I am working on a global functionality for the whole application that simulate the control keyboard button is down. For a JTable the changeSelection method can be used to simulate the control key down, but are their any similar method for JTree or some other solution to the problem.

Thanks,
but I am going to implement a toggle button in the toolbar that are going to work globally. You must be able to toggle on and of and it is going to work in different frames.

  • Sat SP10-804: XP Home thinks Control Key stuck down (XP SP2)

    Satellite SP10-804
    XP home as installed plus SP2
    Occasionally XP thinks that the Ctrl key is stuck down. So it is impossible to log on, Word wants to start in 'Safe Mode' C is always Ctrl-C etc and the only solution I have found so far is a reboot.
    The Ctrl key is not actually stuck down. I have a keyboard utility that indicates when a key (including the ctrl key) is pressed. When this problem is present, the utility does not indicate that the key is pressed.
    So something in Windows has got upset. Right now it is a real pain because I have some serious calculations going on that will take another 8 or 9 hours to finish so I cannot reboot the PC.
    I rather think I must press a combination of keys accidently to cause this problem to happen but I have no idea which keys. Does anyone know
    1) Why this problem occurs
    2) How to fix the problem once it has occurred
    3) How to stop the problem from recurring

    Hi
    I dont know what you mean with Did reinstall. It is really not be easy to say what the problem can be. Maybe some virus or anything else can have influence on to this.
    Unfortunately I have really no answer to this. In my opinion you should back up your data or save all them on second partition if you have one and reinstall the OS using recovery media. Only on this way the unit will be clean preinstalled and you can check if the problem still persists.

  • Detection of the control Key down when application start

    I need to detect if the control key is down when my program start. This program was created with CVI 5.0. Would you tell me how to do it under WIN 9x et NT/2000. Regards

    Normally, for any other key you could just set up a callback function for your panel and set up a case statement for the EVENT_KEYPRESS value for the event type. Or do the same on the initial control that has focus. However, this does not work for the control key, because it does not generate an EVENT_KEYPRESS. Therefore, giving you no option through the normal CVI user interface capabilities.
    Now, you might be able to detect the keypress through windows messaging if you use the function InstallWinMsgCallback found in the Programmer's Toolbox library (toolbox.fp in cvi\toolslib\toolbox) and set up a callback function to look for the message that the control key generates for a window. Other than that, you might have to use some Windows SDK functions, that wait for a keypr
    ess to happen.

  • Simulate that i hold an random Key.

    Hey,
    i just oponend an discussion for an long time ago and marked those as solved, but ihe advice from User called Melophage doesn't helps.
    "Hey Guys,
    i just want to generate an Caps Lock Function for my Option Key, cause of my handicap i couldn't hold this Key anytime.
    Any Suggestions or advices to fix my problem as soon as possible.
    Thanks in advance.
    n1mare.!
    n1mare,
    KeyRemap4MacBook will allow you to set either Option key (or both Option keys) to act as a Caps Lock."
    Hi Melophage,
    i just need to correct my reply. It doesn't works. I don't want to act with my option keys as Caps lock. I just want to simulate, that i hold those Keys. (for example Shift_L & Option_R)
    Hopefully my explanations are understandable and you could help soon as possible.
    Many Thanks.
    n1mare.

    n1mare,
    if you still have KeyRemap4MacBook installed, you can set up a “Control Lock” function through e.g. checking the “▼ Change Control_L Key (Left Control) → Control_L to Sticky Control_L” checkbox — this would turn the left Control key into a Control Lock key.
    Alternatively, you could open the Accessibility pane of System Preferences, select Keyboard on the left-hand side, and then check the “Enable Sticky Keys” checkbox to have all of your modifier keys act as Lock versions. If you choose this option, then I’d recommend also checking the “Show Accessibility status in menu bar” checkbox.
    I don’t know of any program that will set a random key to be a Lock key — the choices in KeyRemap4MacBook are all for specific keys, not for making one random selection out of all of the keys.

  • HELP!  Is there a way to change column information in iTunes such as name of artist, genre etc, other than deleting them one at a time? Such as the way you delete an entire group of songs by holding down control keys or selecting the Select All command.

    HELP!  Is there a way to change column information in iTunes such as name of artist, genre etc, other than deleting them one at a time? Such as the way you delete an entire group of songs by holding down control keys or selecting the Select All command. Thanks.

    If you select all the songs you want to change, Be it one song or an akbum, or an Artist, Or Genre, or playlist. Then Right mouse click  and Get Info. You then get a slightly different from normal Get Info box as this is the One for Multiple items.
    In there have a look at the tags and see if the one you want to changes is in there. There are a few tabs so if for example you wanted to change the Media Type from Home Movie to Movie go to the Options tab and select Movie and OK and it will change the whole selection.

  • I have lost my Safari app and all the bookmarks that go with it. I have tried to download my back-up on external drive but cannot access it. Tried a start with C key held down but still no access to the back-up app.

    I have lost my Safari app and all the bookmarks that go with it. I have tried to download my back-up on external drive but cannot access it. Tried a start with C key held down but still no access to the back up app.
    Have used Superduper app. to back up and checked back-up occasionally to see if all files present  and appeared OK.
    I had previously started machine using original CD #1 to try and replace Eudora which was acting up. Did not knowingly touch Safari.
    Running iMAC System 10.4.11
    How can I successfully download from the Maxtor back-up?
    Ivan

    Further info.
    I checked the content of my other back-up and found the bookmark Bookmarks.plist in the library under Safari
    Dumped the existing copy in the computer and drag-dropped the back up. All bookmarks restored.
    Solved the Stickies problem by using Spotlight  to find file "stickiesdatabase" and did a drag- drop to replace file. All data restored.
    Re Ical data loss. Used Spotlight to find iCal document in  Library - Preferences where I found com.apple.iCal.plist in folder.
    Got ready to make change but did not immediately remove file. When I returned to Preferences folder to grab above document,
    the readable descriptors had been changed to code consisting of some upper case letters and/or single symbols!
    So now I cannot tell which is the symbol  iCal.plist
    Thanks for leading me so far, but how do I find that plist for my calendar?

  • Have to hold down mission control keys, when did this change?

    I have my mission control keys (show windows in app, show all windows, and show desktop) set to use the F10, F9, and F11 keys without function keys.
    Recently (as in five minutes ago) I noticed that the keys are no longer behaving like they used to. I now have to hold those keys to use any of those functions, basically making them useless because now my hand is occupied with that instead of using the trackpad.
    Is there some update that happened that caused this change or is it just a product of some setting getting changed? I never noticed a setting for this in the System Preferences.
    Computer: late 2008 unibody Macbook, 2.5 GHz, 4 GB RAM, running Yosemite 10.10.2.

    Actually just solved my own problem.
    Used killall Dock according to instructions here: https://discussions.apple.com/thread/3831445
    and everything is now working as normal again.

  • What can I do to prevent the control key from not working in the future?

    Background:
    I bough an macbook pro about 1 year and 3 months ago and after 9 months of usage my control key stopped working for about an hour or two.This happened every time I turned on or awoke my mac from sleep (lid down).I sent it to an authorized apple service center and they replaced the keyboard.Everything was fine for about 4-5 months when the same thing happened again, ctrl key stopped working but this time not when turning on my mac but at random times and for random intervals.I sent it again to the service center but they told me that this time it won't be for free because my 1 year warranty has expired.I should mention that in European Union and Romania (the country where I am from and from which the mac was purchased) the law is that any electronics device sold has to come with at least 2 years of warranty.Apple seems to ingore this law.
    Anyway, after long conversations with apple uk on the phone they agreed to pay for the keyboard but not for the labor which was 70 eur ($100).It's not much but my 2 year warranty should have covered it.The sad part is that I have no guarantee that it's indeed a keyboard error and not something else, this might happen again in 4 months and I doubt this time apple would agree paying for the keyboard (which is 150eur) ($215).
    I should also mention that before calling apple uk I tried apple's romanian number (listed on their site) and it didn't work on the 3 phone networks that I've tried (2 fixed and one mobile) which led me to believe that apple support is in fact a big joke.
    Suffice to say that I will no longer purchase any apple devices or software, I regret purchasing mac os x lion just a week ago, when I will no longer use it because I intend to sell all my apple gear (timecapsule, iphone4, macbook pro) and buy stuff from companies that value their customers and respect their contracts.
    My questions are this:
    1) why does apple ignore EU and Romanian law?
    2) what can I do to prevent this from happening in the future
    3) can I request that my macbook be more thoroughly inspected? I suspect the keyboard is not the main problem and it will soon happen again as it happened two times already.
    4) can I do something for the repair labor charge to be waved? It is illegal in my country to ask for one in this scenario...

    Everyone reading your posts here is just another MacBook Pro user. We're all volunteers, not Apple employees. No one here can speak for Apple.
    In my personal opinion, buying Apple products in a country where Apple has no stores and no corporate presence is a risk that the buyer takes knowingly. I don't think it's a wise risk, and I don't recommend that anyone take it. A small percentage of the products sold anywhere are going to have problems, and it makes more sense to buy an inferior product that can at least be serviced locally than to buy a superior product that may have to be sent thousands of miles for repair if anything ever goes wrong with it.

  • Retrival of Control Key of Operation & Table underneeth the structure

    Hi Experts,
       Right now i'm working on PP and PM related stuff, I'm in the middle of the project and stucked down at a point in how to retrive the control key of operation that triggered the update in production order: opoerational view. (CO03).
    Also i have a small question on how to findout the underlying table for a particular field(any field in a screen), when done F1 on that particular field the technical details says as table name but it is actuallya structure. So how should i find the table underneeth the structure where the particular data is being stored.
    Or how should i retrieve the data if i couldn't figure out the table, is there some way that i can retrie the data using the structure.
    Thanks for your contribution.
    Regards
    Rich

    Hi Rich,
    This is a common problem.One of the best and easy way is use the transaction ST05 for trace.lemme explain in detail.
    1.go to ST05 transaction
    2.switch trace on
    3.take your screen where the field resides
    4.enter value in this field and other required field
    5.then save the screen
    6.go to ST05.
    7.stop the trace
    8.click on display trace
    9.you will get a detailed log what all happend
    10.search the log with 'update' or 'insert' word or search with the field.
    11.you can find some table name.
    12.check that table contains the record which you saved.
    Sure this will help
    Another Way
    1.go to transaction se84.
    2.take ABAP dictionary
    3.go to Fields
    4.Give the field name in table field /structure field
    if you are lucky you will get in this

  • Vendor Master post code control in drop down option.

    Hi,
    I want to control In Vendor master drop down option, post code should not display in drop down for particular account group.
    How I can control in drop down option.
    Please help me.
    Br,
    Hanuman.

    Hi,
    As per your requirement, you want supress the drop down specific to the account group for given filed.
    Basically F4 option is coming from the search help defined for that specific field not by the account group. So as long as the serch help designed to that field it will always comes. You can not control that from any field selection keys.
    I hope you understand the concept of search help.
    Thanks,

  • Control key doesn't stop skimming

    I understand "skimming" means that when I hover over my clip, the play line will move along it. Often I don't want this, e.g. I need to reach the menu but now the play line will move all around. I've read in different places that holding down the Control key would pause this skimming, but that doesn't do anything for me.
    I'm using Mac OS Lion with iMovie 11 on a MacBook, and the Control key does work in other programs, so it's not a broken keyboard.
    Can anyone please help? Thanks!

    My best advice if you are working on a certain section is to select it by dragging so that a yellow border is around it. Then you can right click it or use the menu bar without changing what is in focus.

  • Control Key/Mouse Selecting

    I've recently updated my OS X software to 10.4.8 and have noticed a bug with the update. When trying to "label" a folder or item with a particular colour using the "Control" key and mouse combination, the usual drop down menu that should come up no longer does and the screen flips out as if the finder has been relaunched. I now have to go to the "File" menu to select the "Label" selections. I've run a diagnostic; permission repair and disk repair with everything being OK. This bug applies to all user accounts, and other iMacs that have been updated. Can't say how it applies to laptops or towers.
    iMac G5   Mac OS X (10.4.8)  

    You have a bad contextual menu item. Maybe some previously installed extension that is not compatible with 10.4.8
    Look in the "Contextual Menu Items" folder in "Library" at the top level of your disk.

  • Control key locks

    i have an hp g-71167dx notebook.  my control key show as being locked and i have to turn off my computer to clear it.  pc is only 6 months old.  are there any solutions ?

    Hey edlibra and da9132,
    There could be a couple of different causes/solutions for this issue. Here are some suggestions.
    First try pressing both the Left and Right Ctrl keys down at the same time. See if that resolves the issue. 
    By default in Windows Ease of Access Center (Start > Type "ease" > Click Ease of Access Center > Click Make the keyboard easier to use > Click Set up Sticky Keys), Lock modifier keys when pressed twice in a row, is checked. Just uncheck that box and hopefully you won't run into that problem anymore. Modifier keys include Ctrl, Shift, and Alt. 
    You could also see if there is a BIOS update for your particular notebooks. I'll need both of your product numbers and whether you're using Windows 7 or Windows 8. Here are the steps to find your product number. Once I have your product number and version of Windows, I can provide you both with direct links to your latest BIOS driver.
    To find the current BIOS version, follow the steps below (taken from here):
    Windows 8 : From the Start screen, type msinfo32 . Click msinfo32 from the list of results.
    Windows 7 and Vista : Click Start , enter msinfo32 in the search field, and then select msinfo32.exe from the list of results.
    Windows XP : Click Start , select Run , enter msinfo32.exe in the Open field, and then click OK .
    In the System Information window under the System Summary category, look for the BIOS Version/Date entry. This is your current BIOS version.
    Figure 1: BIOS Version/Date
    Write down the BIOS version and post it in your reply.
    Please let me know if you have any questions or if these suggestions helped (this could help other users having the same issue). I'll keep an eye out for your reply.

  • Control Key Stuck At Times

    A couple times a day my computer will act like the control key has been pushed and will open the shortcut that is with the letter I pushed. Sometimes it will cause the page to zoom in and out from scrolling the mouse. I had a L505 and it did this I replaced keyboard they replaced the system board and it still did it. I sold that computer and got a new L655-S5158 it is doing the same thing. This is really annoying because I never know when it is going to do it. Sometimes when I am typing a email or filling out an online forum it will reload the page and I will lose all my work. I thought it might be firefox so I switched back to Internet Explorer still does it. Does anyone know what is causing this.

    Hello,
    I can reproduce this bug (make Windows think the CTRL key is stuck down) at will, and I can unstick it too, on my Satellite L775.
    To make the bug appear, I just hold down the CTRL key while using pinch-zoom.
    To unstick the key, I just press both control keys simultaneously.  This "unstick" method has always worked, except ONE time it did not and I had to reboot to unstick the CTRL key.
    Obviously, the fact that the touch pad itself has a bug that frequently ignores the fact that I have it turned OFF and zooms or scrolls without warning when I get near it exacerbates this CTRL bug, but, anyway, I hope that being able to reproduce the bug reliably will help get it fixed.

  • Control key stuck

    I recently purchased an X131E.
    It's great but after an hour or so of being turned on it acts as if the control key is pressed, and makes it hard work using Office, IE etc...
    A re-boot resolves it, but it just happens again soon after. I'm sure the key is not stuck, what could be causing this? How can I resolve it?
    It's not the sticky keys as I have disabled that after trawling other forums
    Any help appreciated.
    Would this be covered under the warranty?
