Best way to update GUI

Hi, I have a class of "business model" that contains all of my variables that are displayed on my GUI which is a separate category. As these variables change very frequently during execution of the program I need some advice on the best way to update my GUI as needed. I use a controller with actionListeners to cope with the changes in the opposite direction. Then I can manipulate the this approach based on my needs or should I implement Observable I read somewhere else?

I don't see why not. But it depends on how abstract you want to get.

Remember that an "event" is simply the source calling a method specified in advance of the target. In other words, there is a framework in order to hide the details, but in the end, it is simply the JButton calling the actionPerformed method in your controller.

If even you can configure the controller with some methods specified in advance, cause the GUI change somehow and the model call these methods pré-spécifié whenever it was necessary. It would be the easiest way.

But notice that in your interactions view controller, the controller is really interacting with a variety of components from the view. Maybe your model is broken down into a number of components also, and perhaps it would be beneficial for the controller to directly interact with these components. In this case you might want to formalize these interactions, possibly using the observer model events.

  • Best way to update the individual rows of a Table?

    I took a quick glance at a few examples, but did not get a clarification on this.  I am looking to have something close to a listbox control or the table to where I can update just one column of values to line a 1 time per second pace.  I'm looking to display our acquisition of data values in a table or a listbox control.  The single list box seemed to work well for that, but I couldn't use the row headers to list the names of channel beside the channel values.  I thought to link the values of cursor in two areas of list to do this, but did not find any info on it for the single list box.

    I have a few questions:

    (1) I have a 1 d table to where I want to use this data to constantly update the first column (with a multitude of lines) of a table.  I'm looking for the best route to not take too much time for treatment by doing this.

    What is the best way to update the individual rows of a table?   Invoke the node "Value of the cell value"... or is there another method?

    (2) why is that, after each iteration else, row values are deleted?

    Also, for adding additional channels originally arrray... it is better to use the 'Array' subset then the function "Construct the table" or function "Subset of the table" and "insert table"?

    See the attached example.

    Thank you.

    Classic race condition.  dump the loop and node-p and just wire the 2D table on the terminal Board. !

    I don't see the race condition.  What I see is the table once the last element has been written for it all run the oil.  I saw looked it with point culminating performance on.

    But I agree entirely with writing to the Terminal.  It is a 1 d array, so you will need to use an array of generation and convert a 2D array in order so that he could write correctly.

  • What is the best way to update coming 8 Pro?

    I'm a little confused about the best way to update my V8P. The app My Dell seems to be looking for updates, but it is also linked to a page on the Dell site that checks the latest downloads for the device. The link is provided through the tile from drivers and downloads . This page of the Web site, incidentally, trying to install a program to check my V8P, but the facility apparently never works. I always get an error message that says (and I entered here exactly as it appears, the police blue and all):

    "We're sorry, we were able to scan your system. "Please return to the drivers home to return to.

    Because of the link to the site I don't know if My Dell app is all I need. The app has an area of notification, which seems to be to talk about new drivers and such available, although drivers and downloads of tiles wonder is if there is more, I might have need. Why have the drivers and downloads of tiles if the application checks and warns me on drivers and downloads?

    Bottom line, is that I'm confused. So, what is the best way to ensure that my V8P is up-to-date?

    Manually, I downloaded and installed Dell system detect. After doing this I have re-tried the system analyze the updates of the Web page and it worked. I now have a lot of updates available.

  • Best way to update all the lines of a huge table

    Hi all

    I'm on Oracle 11.2 Enterprise edition.

    I asked a question, "assumes that there is a large table, say 3 GB size.» We need to update all rows in this table (e.g. col3 = col3 * 2), what is the best way to do this? »

    My answer was, there are 2 possible ways, depending on the number of indexes on the table

    (1) if there is a lot (or wholesale) index on the table OR the database is in FORCE LOGGING mode (due to log shipping), I just run an UPDATE command on the table and update all records. This will generate a lot of redo and undo, but we cannot do anything for indexes

    (2) if there is not a lot of clues, I'll create an empty table of the same structure (create table t2 nologging in select * from t1 where 1 = 2). Then, using an INSERT... AS SELECT... command, with the ' col3 * 2 "instead of col3, I insert any data into the new table with APPEND tip. Then create all indexes on the new table and finally, rename T2 T1

    In case the first solution, I can avoid the recreation of the index and save this I/O. In the case of newspapers, first solution makes more sense anyway.

    Second solution is logical, if we have the freedom of creating objects in NOLOGGING mode.

    What do you experts? I think in the right direction? or what?

    Thanks in advance

    Hello;

    Let me welcome you on the HP forums!

    Some people have worked a long and complicated way to make the initial win 10 improvement by using additional storage media to contain the update files.  The existing 32 GB SSD is simply too small to hold the existing operating system and the Win10 update files.

    But then they discovered that they could not do the cumulative updates (like the recent anniversary update) because their methof of point to other storage media has not worked!

    Sorry for the bad news, but there is really no good way to update the series flow 11.

    You do not need to start from scratch, you can make sensitive sites but its never going to be as good, or even as a site built with that in mind. Actually, that makes a huge difference to the way a website is designed.

    You can build a site on a development site and the port, we often... But do not think about what changes, what remains the same, how you take it a direct site (about a day or more) replacement of files, 301 redirects if you changed your URL, backups... and so on.

    You can copy your site which will be over of ports of things like pages and products, and you can then delete the templates and css, the js files, etc if you want and go from there.

  • Best way to update a table with separate values

    Hi, I would really appreciate some advise:

    I need to regularly perform a task where I update 1 table with all the new data that has been entered in another table. I cannot perform a complete insert because this will create data duplicated each time it works, so the only way I can think of is the use of cursors in the script below:


    CREATE OR REPLACE PROCEDURE update_new_mem IS
    tmpVar NUMBER;

    CURSOR c_mem IS
    SELECT nom_membre, member_id
    OF gym.members;
    CREC c_mem % ROWTYPE;


    BEGIN
    OPEN c_mem.
    LOOP
    SEEK c_mem INTO crec;
    EXIT WHEN c_mem % NOTFOUND;
    BEGIN
    UPDATE gym.lifts
    Name = crec.member_name
    WHERE member_id = crec.member_id;
    EXCEPTION
    WHEN NO_DATA_FOUND THEN NULL;
    END;
    IF SQL % NOTFOUND THEN
    BEGIN
    INSERT INTO gym.lifts
    (name, member_id)
    VALUES (crec.member_name, crec.member_id);
    END;
    END IF;
    END LOOP;
    CLOSE C_mem;

    END update_new_mem;

    Almost anything would be better than this treatment of slow-by-slow loop.

    You don't need a procedure, you should just use MERGE for this. See the examples in the section of the MERGER of the doc of the SQL language
    http://docs.Oracle.com/CD/B28359_01/server.111/b28286/statements_9016.htm

    MERGE INTO bonuses D
       USING (SELECT employee_id, salary, department_id FROM employees
       WHERE department_id = 80) S
       ON (D.employee_id = S.employee_id)
       WHEN MATCHED THEN UPDATE SET D.bonus = D.bonus + S.salary*.01
         DELETE WHERE (S.salary > 8000)
       WHEN NOT MATCHED THEN INSERT (D.employee_id, D.bonus)
         VALUES (S.employee_id, S.salary*.01)
         WHERE (S.salary <= 8000);
    
  • What is the best way of updating OID and similar attributes via OIM OAM LDAP?

    Our environment uses IOM provisioning of an OID LDAP that is used by OAM.

    Purposes of inheritance, must complete the Oracle "orcl *" attributes and OAM "ob * ' in cases where they use the same or similar.

    Example: When a user is disabled in IOM we define orclisenabled = 'false' and obUserAccountControl = 'DISABLED' in OID

    What is the best way to achieve the IOM? My first thought was to write a custom adapter, similar to the OID adapter change user out-of-the-box, which takes in charge the changing multiple attributes.

    Is there a better way?

    You can create two tasks that will modify two attributes to OID.

    On the task of the user to disable call task1, success of task1, Task2 (using the task to feature generate).

    You can make use of OOTB connector only.

  • Best way to update new XPS8700 drivers?

    What is the best method of updating the drivers? I tried several times to download Dell system detects and while the site thinks that you have downloaded the file, it did not. I used my Service tag to identify my computer and noticed that the first option for the update of the BIOS driver was for the A10 Bios, while my new computer has a Bios A08. So my confidence level in the Dell site for driver updates is not high. It is better to use the Device Manager and download updates individually from there? Or is one of the free 3 software products left that supposedly make it a good option? Thanks for any recommendations you may have.

    Huh?

    If you have the BIOS A08 A10 is available, what is wrong with that? A10 is obviously a newer version than A08 and was released only very recently.

    You cannot use the Device Manager to download the drivers from the Dell site. Your best bet is to look for new drivers based on the material actually installed in your PC (look on the invoice that came with the PC, or click on the Configuration link on the support page).

    You can compare the driver version in device with one offered Manager to see whether or not you have later.

  • Best way to update 8 of 10 million records

    Hi friends,

    I want to update a file table 8 million of a table that has a record 10 million, what could be the best strategy if the table has a column with 600 GB of data BLOB. BLOB itself is 550 GB.  I'm not updating the BLOB column.

    Generally with non-BLOB type data I tried to do ' CREATE TABLE new_table as select < do the update 'here' > from ancienne_table; "method.

    How should I approach this?

    So what's the problem with just issue an update to update all the 8 million lines?  Will there be a simultaneous DML against this table?  If this is not the case, the parallel DML would be an option, although it may not really necessary.  What size are the rows of the base table?  How many indexes are performed by the update as appropriate?  What do you expect the update causes any migration of line?

    Unless you don't have enough Undo to manage the update just a single update statement followed of a validation running seems fine.

    Now if there is a lot of simultaneous DML on the table you probably want to use pl/sql, then you can browse the data delivering a validation every N lines in order not to crash other concurrent sessions on the table for a too long period of time.  This may well depend on if you can write a power slider that can be restarted in the event of interruption and that he could skip the lines that have already been updated.  If this isn't the case, you can use a table of conduct to control treatment.
