• Adding fields to a Manager slows down application

  Is there a reason why adding fields to a Manager directly slows my application?

  In the constructor of my screen, I loop and add 200 LabelFields.  This causes the user interface is very slow.

  However, if I loop and add fields to a temporary VerticalFieldManager and then add only the Manager screen, works fast.

  The disadvantage of this approach is that the user will not be able to see the added both fields.

  I am surprised that I did not notice this earlier.

  Here's the slow code:

  import net.rim.device.api.system.Application;import net.rim.device.api.ui.Manager;import net.rim.device.api.ui.component.ButtonField;import net.rim.device.api.ui.component.LabelField;import net.rim.device.api.ui.container.MainScreen;import net.rim.device.api.ui.container.VerticalFieldManager;
  
  public class TestScreen extends MainScreen {
  
    private static final int NUM_ROWS = 200;
  
      VerticalFieldManager outerRowManager;
  
     public TestScreen() {     super();
  
          ButtonField runBackgroundButton = new ButtonField("Background") {         protected boolean navigationClick(int status, int time) {             new BackgroundThread();               return true;          }     };
  
        outerRowManager = new VerticalFieldManager(Manager.VERTICAL_SCROLL | Manager.VERTICAL_SCROLLBAR);
  
         add(runBackgroundButton);     add(outerRowManager); }
  
     public class BackgroundThread {
  
       public BackgroundThread() {           (new WorkerThread()).start();     }
  
         private class WorkerThread extends Thread {
  
           public void run() {
  
               for (int i = 0; i < NUM_ROWS; i++) {
  
                   synchronized (Application.getEventLock()) {                       outerRowManager.add(new LabelField("ROW " + i, LabelField.FOCUSABLE));                    }             }         }
  
         } }}
  

  And here is the quick code:

  import net.rim.device.api.system.Application;
  import net.rim.device.api.ui.Manager;
  import net.rim.device.api.ui.component.ButtonField;
  import net.rim.device.api.ui.component.LabelField;
  import net.rim.device.api.ui.container.MainScreen;
  import net.rim.device.api.ui.container.VerticalFieldManager;
  
  public class TestScreen extends MainScreen {
  
      private static final int NUM_ROWS = 200;
  
      VerticalFieldManager outerRowManager;
  
      public TestScreen() {
          super();
  
          ButtonField runBackgroundButton = new ButtonField("Background") {
              protected boolean navigationClick(int status, int time) {
                  new BackgroundThread();
                  return true;
              }
          };
  
          add(runBackgroundButton);
      }
  
      public class BackgroundThread {
  
          public BackgroundThread() {
              (new WorkerThread()).start();
          }
  
          private class WorkerThread extends Thread {
  
              public void run() {
  
                  outerRowManager = new VerticalFieldManager(Manager.VERTICAL_SCROLL | Manager.VERTICAL_SCROLLBAR);
  
                  for (int i = 0; i < NUM_ROWS; i++) {
                      outerRowManager.add(new LabelField("ROW " + i, LabelField.FOCUSABLE));
                  }
  
                  synchronized (Application.getEventLock()) {
                      add(outerRowManager);
                  }
  
              }
  
          }
      }
  }
  

  The answer is actually quite simple. Every time that you add a field to a Manager, updateLayout() is called. In the first example, you already added "outerRowManager" to the screen and it was posted until you start adding LabelFields. In the second example you add fields to the Manager until the Manager has been added to the screen and displayed. Its always faster to add bottom up (onscreen Manager fields)... In addition, you are synchronizing with the interface thread user 200 times compared to 1 time.

• I have a table of the adf, I added a column that contains a button that I created, when I click it must remove this row in the table, but it is not, please help

  I have a table of the adf, I added a column that contains a button that I created, when I click it must remove this row in the table, but it is not, please help

  I don't understand. You use vo and eo for you to use business components.

  Again, this kind of code call in trouble.

  You must post the changes to make them visible to the eo find vo. You must then run the query for the changes in the business layer strips then you must update the iterator he table is based on.

  In your code I see that happen, hooch maybe because it is more often than not formatted and undocumented.

  My advice is to do a small test case that you can manage with easy sql. Once you get it to run transfer you the results to the actual application.

• ID of passage with its values in the fields in form when the button is clicked.

  Tried to pass the value according to the button clicked with his id in to form.

  I am able to get the id in the right place as you can see in the Image below, but not able to pass all the different values of it.

  Global function:

  function get_id (id)

  { var a = parseInt (id)

  Apex. Item (P73_SHIP_ADDRESS_ID). SetValue (a);

  }

  
  

  Static page source:

  declare

  Id1 number (10,0);

  Start

  for rec in (select * from OMS_SHIPPING_ADDRESS where USER_ID =: P1_USER_ID)

  loop

  Id1: = rec. SHIP_ADDRESS_ID;

  sys. HTP.p ("< br > < div >");

  sys. HTP.p ('< a >' | sys.) HTF.escape_sc (CRE. TYPE) | "' < /a > < br / >"

  || sys. HTF.escape_sc (CRE. ADDRESS_LINE1)

  || ' , '

  || sys. HTF.escape_sc (CRE. ADDRESS_LINE2)

  || "' < br / >"

  || sys. HTF.escape_sc (CRE. CITY)

  ||  '-'

  || sys. HTF.escape_sc (CRE. ZIP_CODE)

  || "' < br / >"

  || sys. HTF.escape_sc (CRE. STATE)

  || "' < br / >"

  || sys. HTF.escape_sc (CRE. COUNTRY)

  || ' < br / > < input type = "button" value = "sΘlectionner" onclick = "get_id (id)" id ="" | recomm. SHIP_ADDRESS_ID | ' ' ' > '

  );

  sys. HTP.p ("< / div > '");

  end loop;

  end;

  Below the Image if I click select can pass id to send the address id but able to pass the address line1.line2, city etc...

  I tried to move to the global function also does not work! If someone could guide me!

  

  Hello

  If you have already passed the ID, then why don't you create a dynamic action on change of SHIP_ADDRESS_ID and load the details of database and fill in other areas.

  In this way the use of ID is understandable.

• Problems with adding fields of digital signature

  OK, so I'm an IT Manager / developer DB for a defense contractor. And I consider myself reasonably technically competent in MOST things. But this problem has left me speechless (for the most part) for lack of decent instructions or advice are on the lines.

  , I'm looking to create a form for use by the employees of my company to follow the 'signatures'. we have so far put in forms manually signed for this purpose, my goal is to go paperless with this process. I know it can be done because the air force (my client) uses a form that allows you to do something similar (see here: http://www.dtic.mil/whs/directives/infomgt/forms/eforms/dd2875.pdf). Forward listed form allows you to 'click' on the signature block and add your digital signature (which, for the AF, comes from an IDENTITY card). Let explain me the dev environment, I am using / testing on:

  Creation of the form:

  I use my laptop with my own personal copy of Adobe Pro 9. I have no installed dig signature or any ability to use on this system. I CAN, however, add the field to the GIS during the creation of the form and the field responds when you click on it, but with a command prompt different than the 2875 (I think this may be part of the question). Then I tried sending it to my AF computer to test whether it will actually allow me to add a signature block.

  Tested the form:

  On my AF computer I only software adobe reader 9 installed, and it will allow me to add my signature to the DD 2875. When I do my newly created form with my added field GIS that nothing happens at ALL when you click it.

  Troubleshooting:

  I first noticed that under form properties security has been put in place to NOT allow the signing. I changed that and returned on one system to the other, and it seems that in the translation he loses this setting. First, I assumed it might be due to the security the AF place on its e-mail servers. So in response I burned the form of a cd and manually transferred but got the same result.

  Conclusion:

  I terribly bit educated on the development of PDF I suspect to understand everything that happens here, but I feel there's a script attached to the FA form that works and allows him to function properly. If this is the case I don't know what recourse I have, if any. BUT, if its something simple that I'm missing just in cause of my lack of experience I hope someone here can help me.

  Thank you!

  Hi LBitner99,

  Before you can use Adobe Reader to add a digital signature to a PDF document, the file must be "enabled for the drive.  There are two ways to do this, you must use a server, what the DoD because they need to drive helps thousands of documents. The other way is to use Acrobat Pro (I know that you said you have Pro, but for anyone else reading this has has Acrobat Standard, this version is not the feature activate Reader).

  With the file you worked on open in select Acrobat the Advanced > extend features in Adobe Reader menu item. Click the Save button in the dialog box that followed, and the new file will have digital signature rights in Reader.

  I hope this helps.

• touch events for several fields in the Manager of several

  In my application... I have a vertical field (VFM) Manager in the screen.

  In this optimization of resources, I inserted 3 manaagers:

  (1) District Manager hfmHeader horizontal (in which I added 1 label (NON_FOCUSABLE) and 1-2 Btns according to the conidtion (tuochEvent FOCUSABLE and overrried all in initlilsing it).)

  (2) District Manager vertical ListField container or TextField or LabelField vfmManager in accordance with the condition.

  ((3) District Manager horizontal hfmButtons containing 6 btns... all tuochEvent FOCUSABLE and overrried initlilsing while the).

  public int getFieldAtLocation (int x, int y)
  {
  XYRect rect = new XYRect();
  int index = getFieldCount()-1;
  While (index > = 0)
  {
  getField (index) .getExtent (rect);
  If (rect.contains (x, y))
  break;
  -the index;
  }
  return to index.
  }

  Second, the click event try something like:

  protected boolean touchEvent(TouchEvent event)
  {
     switch( event.getEvent()  )
     {
          case TouchEvent.CLICK:
            int index = getFieldAtLocation(event.getX(1),
                                           event.getY(1));

            if (index == -1)return true;
            Field field = getField(index);
            if(field.equals(bitmapField))
            {
              System.out.println("Bitmap Clicked");
            }
          return true;
     }
     return super.touchEvent(event);
  }
  

  Even when I am using above solution, can't scroll. and click event of the hfmButtons buttons aren't the gt performed.

  Second... If I don't stand... I am able to scroll and executed at least the first 3 buttons click event.

  How can I implement for each button click event in any Manager? Is this possible...

  Can someone please help in this regard. Any suggestion or if possible code snippet will be appreciable.

  Thank you

  Use the snippet for each manager of...

  case TouchEvent.CLICK:
  India = getFieldAtLocation (event.getX (1),)
  event.getY (1));
  If (India! = - 1) {}
  Field fm = getField (India);
  {if (FM. Equals (vfmMain))}
  int index1 = vfmMain.getFieldAtLocation (event.getX (1),)
  event.getY (1));

  If (index1 >-1) {}

  Field = vfmMain.getField (index1);

  check field is instance of the field you want

  {if (Field.Equals (footerManager))}
  Container.isFooterManager = true;
  int index2 = footerManager.getFieldAtLocation (event.getX (1), event.getY (1));

  Search fields in the Manager of this...

  } ElseIf... {

  go on the same cehcking

  } ElseIf {}

          master.Application.changeScreen(Version);
      }
  }
  

  I've defined several buttons for the main Menu.

  How can I add these buttons Actions?

  I added one already to the Exit button. We work.

  My first idea was to add a method to implement the InfoScreen.

  But I get a Java error.

  Browsing through the Internet I have not found a solution.

  I took most of the developer Sources.

  But I don't know what I should do now.

  How can I declare different Actions for different buttons?

  2. question.

  I am swaping with screens with the pushScreen command.

  Is there a way to return to the previous screens?

  1 Add this as a change listener to each button.  In your fieldChanged method, mount ButtonField field, extract label and branch code according to it.

  2. pop removes the screen from the top of the stack so underneath the screen becomes visible. Stack screen blackBerry is just that - a battery.

  By the way - are you sure that you have found the font Times New Roman family?  There is no such family on BlackBerry.  Extract his name by using fof.getName () and display it in, say, Dialog.info - you might be surprised.

• Two-button click

  Hello.

  I have a puzzle, which I can't seem to difficult.

  I have a button on the stage that works very well and perform various actions.

  I have a movie clip on the stage, which contains 10 different buttons that when you click on the button next and done different things and so on and so forth. Once again independently this clip with buttons works fine.

  What I want to do but is it...

  I want to click on the home button on the stage, have that 'click' are replicated to the other button in the movieclip so that I can action both with a single element.

  Any ideas please?

  Thank you

  If you have an object (for example, mc.btn1) with an onRelease handler defined, you can use;

  MC.btn1.onRelease)

  to trigger this Manager.

• Button Click event

  Hello

  I added a button on the screen of my Blackberry and I have a class called WebCall who has the Socket connection

  Citing a treatment on a button click has been discussed on this thread:

  http://supportforums.BlackBerry.com/T5/Java-development/pushing-screen/TD-p/2399831

  In this case, you should be aware that the button click process runs on the event Thread.  But to make blocking as network activity operations, you must do this in your own Thread:

  http://supportforums.BlackBerry.com/T5/Java-development/what-is-the-event-thread/Ta-p/446865

  http://supportforums.BlackBerry.com/T5/Java-development/blocking-operation-not-permitted-on-event-di...

  So, you need start a Thread to do the treatment on your network.  Processing on BlackBerry thread is quite similar to the standard Java Thread processing, so there is no specific documentation of BB for this, but you should a lot of samples of Java if you look around.

  According to the first link that I've referenced, I would recommend that you study the samples you will find.  They will never do exactly what you want, but while you are learning, it is better to start with a sample of work and make small changes to get to what you want, try to create everything from scratch.

  And you should make yourself familiar with this micro-site:

• show/hide a field (table) by using a button.

  I have a table set to hidden and want to display it using a button and hide it using the same key. If the table is not visible I don't want to be printe. Any suggestions?

  Thank you

  -Very well, it looks that it does not keep the flow of the form...

  Another work around you can use this work for you would be the following:

  1. keep this code in the button click event

  If (Table1.presence == 'hidden') {}

  Table1.presence = "visible";

  } else {}

  Table1.presence = 'hidden ';

  }

  2. in your hierarchy, click the table that you want to hide when printing, go to the case of pre-printing and put this line (prePrint is before printing)

  This.Presence = 'hidden ';

  3. now, in the event of postPrint, you can put the following line to replace the visible table (postPrint is after printing)

  This.Presence = "visible";

  Do not forget that if the Table is hidden when printing, the table appears in the postPrint.

  So if you want to avoid this problem, you can have a hidden text field that keeps track of how you should view the table after printing.

  If you do this, you can change the 'visible' to TextField1.rawValue value

  You can put the value of the text using the click event of the button field, when changing the value of the presence of the table changes the value of the text and field

  I hope this will help you!

• Insert a row into the table on a button click

  Hi all

  I have a table called 'temp' with 4 columns such as seq, name, event, id and I have a GP with 3 text such as name, event id fields

  now my question is

  If I enter values in the 3 text fields on this page and a button, click on (for example create), I wanted the values of dose to get inserted into the table 'temp' and

  regarding, "seq" column I HAV created a sequence for it.

  so 1. How to insert values into the table by entering the values in the page

  2 wat shd b made to column seq... (shd b anyth made apex pages or wil automatically get values for each input line)

  pls help me...

  Thanks in advance

  1, it is up to you change your account to something more user-friendly than '8f4692cc-040e-48ee-b102-590cdd4303fc'.

  Then, it would also be a good idea to use proper English when you ask a question here...  Not broken English as "now comes to my" and "wat shd b"... More people will be willing to help you if you at least put forward in order to ask a good question...

  Which version of the database are you using? APEX version?

  Change the code above to this process:

  DECLARE

  v_seq NUMBER;

  BEGIN

  
  

  Select SEQUENCE_NAME. NEXTVAL INTO v_seq

  Double;

  
  INSERT INTO temp (seq, name, event, id)

  VALUES (v_seq,: P1_name,: P1_event,: P1_id);

  END;

  
  

  This allows it to be used in older versions of Oracle that do not allow direct access to the sequence.nextval in an assignment statement.

• If so many conditions, including the next button click

  I just want to use Javascript (generator of action a fits on several "trigger" conditions).  As if previous/next statements I used just .rawvalues of the radio buttons and checkboxes.  Now, I want the event to occur (navigation of page x) when the user clicks on the next button AND a value of box 1.

  I don't know & & to join conditions, I do not know how to code in a rawvalue for an OK button.

  Is there a clean way to do this?  I don't want a dozen becomes visible and Ok buttons occupying the space given to a value of the check box. This seems a bit awkward.  I'd appreciate any help!

  Hello

  Buttons do not hold the values - you can't assign a value to a button.

  Normally, you put a script on its Click event, solutions for you would be

  • have a hidden field or a formVariable) store if a click has occurred.
  • change an attribute of the button (such as the fillColor) when clicked and have then other scripts look for that. A click event of button change fillColor does not calculate the events of shooting, so if you want a script on the calculation event to run in response to a change in the fillColor, put a

  TextField1.execCalculate (); at the end of the script.

  Here is an example:

  ///////////////////////////////////////////////////////////////////////////////

  Form1. #subform [0]. Button1::click - (FormCalc, client)

  $.fillColor = "255,255,255" //button click changes its own fillColor

  TextField1.execCalculate (//then) fires the script below

• Update a Date field when I press a button

  Hi all
  I have a form and one of the fields is the created date entry. I currently have it set to SYSDATE, but if I go to the form and wait a few minutes and then submit, it keeps the sysdate she filled with but I really want to be put in this field is the time when I click on the button create. Any advice on how to make this happen? Then I could just make the invisible area and when he clicks on create to write the date time they click on the button create the database.
  
  Example, I go to the page to create an entry at 12:50, but I don't send the entry until 12:55, because I have the default sysdate value, she fills the field at 12:50 and what I really want to do is to fill in the field to date at 12:55
  
  Hope that makes sense.
  
  Thank you
  Wally

• Two variables need to be set and reset as two different buttons are pressed

  How to define variables and reset the variables when different buttons (one at a time). They go to the same page, but their actions are taken based on the setting of variables.
  
  Examples or suggestions will be highly appreciated.

  keep going to the page as hidden. Pass a value to this hidden point. Based on the hidden item, the button appears.
  For example if: Pn_X = 1 display button1 if: Pn_2 = 2 display button2. Pass the value to Pn_x, you have your own conventional logic
  Another example on the use: I do not have a process button and create the Bill once I clicked and dealt with the Bill, I put the element hidden under another value. Immediately, print the invoice button will appear, and the process button disappeared. Once printing is complete, this key will also have disappeared and create a Bill button will appear. and this cycle
