Problem in scrolling a JTextArea

hi,
I am using a JTextArea to display files. I could scroll smoothly without interruptions when I tested with a 1 kb file. But when I loaded a 300 kb file, the scrolling beacame halted and slow. It was not continuous. Can this be fixed?
Also I am thinking of displaying files of larger sizes( 1Mb- 5 Mb). In such cases, I thought it would be better to display only parts of the document as i scroll. Could someone please help me with this?
Thanks,
ramya

Hello,
I hope you would be able to recall my problem - smooth scrolling of loads of text.(Please see my problem -right at the top, as the first post)
I worked out a way to display only the required text as i scroll. I could not go in for a scrollpane because I would need to deal with MBs of textual data. :(
Now, I am trying to perform a word search on the text displayed. I do not know how to do this.
Please help with your suggestions and pointers.
I have posted the code below.

  • Problems with scrolling and Mission Control

    I have this problem:
    When scrolling down any page, the letters will blur at the top of the screen and not the bottom.
    When swiping acrross pages in the launchpad, it occasionaly freezes half way between the two.
    When I swipe up with four fingers to access mission control, the screen becomes very sluggish. Swiping back down (or clicking a tab) is even worse, causing slow "laggy" animations.
    And this the report from EtreCheck:

  • Help: Problem with scrolling my html items and placed objects they keep cutting through my top menu

    Basically whenever i place an html item in my Muse site or an object I encounter a problem when scrolling down past that object in the preview. I have a horizontal menu bar that sits on the top of my site and whenever I scroll down the html items and objects
    cut through my menu. Is there any way to rectify this? - i've tried pinning objects but can't figure it out. Any help would be greatly appreciated.
    Thanks,

    So you have a pinned Menu in the Master page but is being overlayed by the objects in page when you scroll down? If that is the case, select the Menu in the Master, right click on it and Move To Master Foreground.
    Thanks,

  • Problem with scrolling a panel containing an image

    I am having a problem adding scrolling capabilities to a tabbed panel containing pages containing an image. In my program, I have a class called ImagePanel that extends JPanel and contains an image read from a file. In another class, I create a tabbed panel and add to it ImagePanels.
    The problem I'm facing is that the pages added to my tabbed panel contain scroll bars, but these scroll bars are not scrollable (i.e. I cannot use the bars the scroll and see the missing parts of the image).
    Any help on this manner is highly appreciated.
    The code is shown below:
    JTabbedPane m_pathwayTabbedPane = new JTabbedPane();

    JScrollPane graphcrollPane = new JScrollPane(overviewPanel,

  • Problems when scrolling

    Good afternoon, I am facing a problem when scrolling a page when in the continuous view, sometimes the page jumps to the previous lines... How can I fix this?

    I've only got one paint method and that is the main one in the base class. I've actually always disliked it. It basically contains all the location setting of all the components on the applet. I always thought these should be put in init, but whenever I do that, it fails to set their location.
    Still, this is what my paint method looks like (well, a bit of it, its long)
    public void paint(Graphics g)
             //Empire Choice
             empire.setLocation(215,21);
             //End Empire Choice
             //Implants Choice
             implants.setLocation(10,layoutArray1[29]);
             //End Implants Choice
             //Mode Choice
             mode.setLocation(177,51);
             //End Mode Choice
             //Templates Choice
             templates.setLocation(235, 81);
             //End Templates Choice
             //Implants Chosen List
             implantsChosen.setLocation(10,layoutArray1[32]);
             implantsChosen.setSize(110,60);
             //End Implants Chosen List
             //Implants Description Label
             implantsDesc.setLocation(10,layoutArray1[30]);
             implantsDesc.setSize(275,15);                
             //End Implants Description Label
                etc
                etc
                etcI really think its wrong, but i've not been able to work out how to make it 'propper' (I mean, it works and everything, but it seems wrong to me). Like I said, we haven't been taught much on applets at all, so i've had to teach myself all of this :-/
    Thanks.

  • Problems with scroll bars in list view

    Hello,
    I am using Xcelsius 2008 (Build Number 12,2,166).  I am still having trouble with scroll bars on my list view control. Other list views in my dashboard seem to be ok. It seems that this list view is not ignoring the blank cells in my excel file. I have gone through many things to correct this problem. I have added a new list view, I have copied other list views that work correctly but still no success. It seems that the "Ignore Blank Cells" property is not working correctly. Does anyone have a solution for this?
    Much Thx!

    Hi Yusufel,
    Please check the data whether the cells are really blank or having any space which could not be seen, etc.
    With best wishes
    BaaRaa.

  • Problem in SCROLLING  of TABLE CONTROL which is designed using WIZARD

    Hello Friends ,
                              I have designed a entry screen by using table control with wizard.  My table control layout  has 11 rows. I have used all 3 facilities i.e. SCROLLING , INSERT/DELETE  & SELECT/DESELECT by cheking ( ticking ) check boxes while designing table control with wizard.  
      Now i have 3 problems.
    1> In my entry screen , if 11 entries are entered , they are displayed in entry screen and are saved correctly in DB.
         But when  i copy a file of suppose 15 entries into entry screen then it displays only 11 entries in entry screen and after that  if  i click/move  VERTICAL SCROLL BAR to see remaining/next 4 entries  then it does not display  12th 13th 14th &15th entry in entry screen. So the problem is i am unable to display remaining/next 4 entries  in entry screen & also to save them DB.
    2>  At the same time when i click/move  VERTICAL SCROLL BAR to see remaining/next 4 entries  then  earlier 11 entries  are disappeared/ get cleared from entry screen.
    3> The FIRST PAGE, PREVIOUS PAGE , NEXT PAGE , LAST PAGE and INSERT , DELETE push buttons are dispalyed in my entry screen . But they are not working or doing their opertions on table control though there is system generated code for them written in module pool program and  PBO & PAI OF SCREEN 100 on which table control is present.
       So eagerly waiting for POSITIVE replies  &  Correct solutions from all ABAP techies.
    THANKS & REGARDS,
      Ashish.

    Hi friend,
                         I have visited the link u have given . But it is a report program .it is available in ABAPDOCU tcode.
    ABAPDOCU----
    >ABAP User Dialogs -
    >Screens -
    >Complex Screen Elements -
    >Table Control with Scrolling .
    It is a REPORT program. and not a module pool program. plz check this in ur link also.
    REPORT demo_dynpro_tabcont_loop.    &
    *SELECT * FROM spfli INTO CORRESPONDING FIELDS OF TABLE itab.* -
    > this statement is used only in report program and system does not allow us to use in module pool program.
    Second thing here data is retrived from spfli table where as my data will be whatever enduser enters it may be 15 lines , may be 50 lines or may be 200 lines and it shold be displayed on entry screen before clicking SAVE or any other user action.
    My main problem is that I am unable to enter more than 11 entries in my entry screen. I want dynaamic table. Mean whichever enteries are entered they should be displayed on entry screen as well as can be scrolled up & down before saving and get saved after clicking SAVE button. here table control design is not imp because entry data depends on table control layout rows & which has limit. It can not be extended beyond certain level. i think max will be 20 Or 25 rows in layout. How to make it dynamic so that we can get any no. of entries in entry screen hiich canbe scrolled up & down.
    Anyways thanks for ur reply And send some other soln.
    Thanks & regards,
    Ashish

  • Problems with scrolling after mountain lion download.

    I just downloaded mountain lion today and ever since the download I am having issues with the scrolling for my magic mouse and trackpad. My problem is when I scroll down on my mouse or trackpad it actually goes up on the page and vice versa. I have seen others have had some scrolling issues but not exactly the same as mine. Just wondering if there is any known fix for this problem? I did the PRAM reset and also the SMC reset and that didn't fix the problem unfortunately.

    Look in System Preferences > Trackpad (or mouse) > Scroll & Zoom tab > uncheck Scroll direction: Natural.
    The scrolling direction has been changed to a technique where your push the screen up or pull it down, takes a few days to get used to.  The swipe directions will also be affected by this change.

  • Problems with scrolling through premiere timeline using arrow keys and shift arrow

    This is a really weird problem in cs6.
    When I load a clip into the source monitor i can scroll throughit fine using the arrow keys, and shift arrows and my shuttle pro controller.
    When I place the same clip on to the timeline it really struggles to scroll using the arrows or the shuttle pro, its really kerky and sdlwo to scroll the timeline, which is really frstrating, becuase it can play the footage fine in the source monitor.
    The clips will playback fine, but scrolling through them just doesn't work as it should any ideas?
    Cheers
    Mike

    I changed my shuttle settings to make the shuttling more responsive:
    1 - 5 times second
    2 - 10
    3 - 15
    4 - 30
    5 - 45
    6 - 60
    7 - fast as possible
    At least I changed this a long time ago - don't know if these are the defaults or not.
    It'll only shuttle as fast as your system is responsive of course - so if you get instantaneous scrubbing by dragging the CTI in the timeline with the mouse, you should be able to get good performance with the shuttle. Of course that performance depends on the type of footage and how demanding it is on CPU to decode and whether youi have effects applied etc etc etc.
    I edit pretty much exclusively with Sony XDCAM EX 1080P 25 footage we've shot on EX3 and PMW-350 etc and I get very very fast performance on the timeline - no issues at all i7 6 core 4GHz with 24Gb ram and fairly fast RAID array for footage.

  • Flash button problem when scrolling

    Hello.
    I posted this in Dreamweaver forum as well....just in case.
    I am using flash buttons for email links in my web site
    rather than html email links to help with spamming.
    They work great except for one thing. In my site I have a
    fixed Div on the left of my pages. The content scrolls sideways
    underneath the fixed div. However....the flash buttons scroll over
    the TOP of the fixed div while the rest of the content goes under
    as it is supposed to. I have the fixed div set at z-index of 2.
    This isn't an issue in Firefox, only IE7, so far.
    Any one know of an easy fix for this rather than creating a
    new div for each of the buttons?
    Here is the link to the problem page - its the email link in
    red towards the end of the page. Watch the link go OVER the drums
    as you scroll. (it should go under)

    Thanks in advance for any help.

    Hello,
    Try this and see if it works
    In your HTML go to where the <object> tag is that loads
    your flash button.
    Add this parameter within it.
    <param name="wmode" value="transparent">
    Then add the following inside the <embed> tag
    wmode="transparent"
