How to detect the line wrap event of JTextPane?

Hi all,
I'd like to detect the line wrapping event of JTextPane, so as to adjust the visible rows of JTextPane. How could I do this? Thanks!
Yi Bing

there is no wrap event.
Wrap happens during relayout. The event which invokes relayout could be different. E.g. change size or chane model (document).
Just add document listener and componnet listener.

    How to detect the HTML extension window close in In-design? Does the In-design throws any event on opening/closing of extensions?
    I have a HTML extension running in In-design CC 2014 version.
    I want to perform some required set of actions before my extension window is closed(by clicking on the cross button on top right corner).
    Does In-design throws any event for it? Or can we capture it using C++ plugin in some way?

    Naah.......haven't got any event for that yet.
    Although, since HTML extensions are using chromium browser,  as a workaround, u can attach listener to HTML onClose event, but it won't solve any purpose if you
    are looking to logout session or do some business login in your code.

  • How to detect the key enter with a numerical control without using loop event?

    I want to accept a numerical value only when the key enter is pressed, but without using the event. How to detect the char "enter" with a numerical control?
    Thanks!

    When the user edits a numeric control with a keyboard, its property "key focus" is true. When the user hits enter, key focus becomes false. Poll the property to latch the control valuse at the true-false transition. That won't work if the user modify the control using up and down arrows.

  • How to use the table maintenance events for validating the input entries..?

    Hi,
    I have created a Z table with 6 fields in which all are KEY fields. All are of CHAR type. I have created the Table Maintenance Generator for the same. While maintaining the entries in the table, even though I maintain a blank entry for a field it is saving the entry. But, I don't want that way. All the fields are mandatory in my table. One should enter all the fields. Otherwise it should not allow to save the entry. So, I think it can be done using the Table Maintenance Events. can someone tell me how to use the Table Maintenance Events. and which event to use for my reuqirement and what is the logic to be written.
    Or Is there any other way to solve my problem.
    Please share your inputs. Thanks in advance.
    Best regards,
    paddu.

    In the table maintenance generator, Environment --> Modifications --> Events then a screen will be appear here,we need to create the Events.In the EVENTS screen, press new Entries, there give 01(Before Saving the Data in the Database) and give a name(This will become a PERFORM), then click the Editor pushbutton, this will be there at the right side of the entry, then a popup will be appear, you can create an include program, there inside of the include program write ur code.
    Here is documentation for Event 01(Before Saving the Data in the Database )
    Event 01: Before Saving the Data in the Database
    Use
    This event occurs before new, changed or deleted entries are written to the database. Other activities can be performed, for example:
    hidden entry processing
    fill hidden fields
    flag data to be written to hidden tables after the database change.
    To have the changes saved by the central maintenance dialog routines, SY-SUBRC must be set to 0 at the end of the routine.
    Realization
    This event has no standard routine. The following global data is available for the realization of the user routine:
    internal table TOTAL
    field symbols
    field symbols <ACTION> and <ACTION_TEXT>
    <STATUS>-UPD_FLAG
    If internal table data are to be changed before saving, t he changes should be made in both the internal table TOTAL and in the internal table EXTRACT.
    FORM abc.
    DATA: F_INDEX LIKE SY-TABIX. "Index to note the lines found
    LOOP AT TOTAL.
    IF <ACTION> = desired constant.
    READ TABLE EXTRACT WITH KEY <vim_xtotal_key>.
    IF SY-SUBRC EQ 0.
    F_INDEX = SY-TABIX.
    ELSE.
    CLEAR F_INDX.
    ENDIF.
    (make desired changes to the line TOTAL)
    MODIFY TOTAL.
    CHECK F_INDX GT 0.
    EXTRACT = TOTAL.
    MODIFY EXTRACT INDEX F_INDX.
    ENDIF.
    ENDLOOP.
    SY-SUBRC = 0.
    ENDFORM.

    Joy.

  • How to protect the lines in smartforms

    hi gurus
    i want to know how to protect the line in smartforms..
    regards
    baskar

    Check this link.
    http://www.saptechies.com/smartforms-protect-lines-in-main-window/
    if you are using tables, there are two options for protection against line break: – You can protect a line type against page break. – You can protect several table lines against page break for output in the main area.
    Protection against page break for line types – Double-click on your table node and choose the Table tab page. – Switch to the detail view by choosing the Details pushbutton. – Set the Protection against page break checkbox in the table for the relevant line type. Table lines that use this line type are output on one page.
    Protection against page break for several table lines – Expand the main area of your table node in the navigation tree. – Insert a file node for the table lines to be protected in the main area. – If you have already created table lines in the main area, you can put the lines that you want to protect again page break under the file using Drag&Drop. Otherwise, create the table lines as subnodes of the file. – Choose the Output Options tab page of the file node and set the Page Protection option. All table lines that are in the file with the Page Protection option set are output on one page

  • How to detect the path of Temp directory

    I am writing a class library which allows users to manipulate a database in the web server java applications/applets. In my logic the Application/Applet communicate with a CGI script/Servlet in the server and that do all the database handling. My objective is to make the Client independant from the Database Drivers, and to some restrictions and possible security threats that can arrice when accessing the database directly.
    99% of the work is done and now I am doing the fine tuning.
    My Problem:
    When the user downloading a blob object from the server database. each time the program read the blob it will get a new copy from the server. This is not good if the blob is large (few 100 megs) . So I am going to implement a cache system. but the problem is If I am caching in the memory it will not support large objects (Memory is a limited factor). So the preferance is use the Temperary files but I do not know how to detect the path to temperary folder.
    And my 2nd questions is are the applets allowed to write and read in temperary folder.

    The Java default temporary file path can be determined with
    System.getProperty("java.io.tmpdir")This is typically the same value as the os environment variable

  • How to change the line item storage location during the sales order creatio

    How to change the line item storage location during the sales order creatio

    Hi Kumar,
    I think you can just delete it in the sales order directly, if you are using make-to-order scenario, then there will be special stock left for the sales order as the production has been goods receipt, you need to use MM transaction move the stock to unrestricted use stock. If you are using make-to-stock scenario, there should be no further problem. If you are using assembly order, please try to reject the sales order item to see if it could fullfill your requirement.

    Are you another student who feels the need to post their "student ID" number as a part of the message?  There is really no need to do that, it is meaningless to us.
    You should ask your instructor to answer your questions rather than allowing them to turn the whole class of students loose on the forums usually asking the same identical question.
    At least in your case, the question is different from most we've seen.  Unfortunately, you haven't asked a clear enough question for us to understand what you are talking about.
    What "events" are you talking about?  Post a VI that demonstrates the code that you have written so far.

  • How to detect the final loop iteration of a step in a PostStep Engine Callback?

    I see the need to use a PostStep Engine Callback and look at the Step.Result container of the caller.
    My issue: If the caller is configured to loop, the PostStep Engine CB executes with each iteration and I do not see how to detect the final iteration (which is the only iteration I am interested in).
    Ideas are welcome. Thanks in advance,
    Guenter

    Guenter,
    well, the way i discripted IS the generic way. The reason for this is the following:
    You can compare TestStand very well with procedural programming languages. So you have variables with different lifetimes and scope. RunState is one variable, which is available in every scope, but it may have different content.
    So you leaving the execution of your clientsequence in order to call the callback, you leave the scope of the RunState from your clientsequence. But only there the information is stored on how many iterations are left. It does not make sense to pass this anywhere, since the execution of your clientsequence has to decide if to loop further or not.
    But, please note that there are different scopes for the "disable result recording" as well. You have found the most global one, the station option. But you can as well set this in the sequence settings (Edit >> Sequence Properties >> Disable Result Recording for All Steps) and at step-level (Run Options >> Record Result {uncheck it}).
    Looping on a single step using the step settings, you can additionally choose not to record results for each iteration. This will lead to only a single entry in the ResultList, the overall result of the looped step (if resultcollection is enabled of course!).
    hope this helps,
    Norbert
