Change a UI text field from within a Thread

My program has a thread that's busy churning away. It's a runnable called from within my classes main. The UI element is built by a method in the class.
If I try to report something from within the thread by doing a myText.setText("success"); I get a crash:
Exception in thread "Thread-1" org.eclipse.swt.SWTException: Invalid thread access
followed by a bunch of SWT.error messages related to that line. The field myText is defined globally for the class.
What is a good way to be able to write stuff to a UI from within a thread? I could do it when the extended Thread was defined within my main() by creating a runnable also in my main() that got called through a syncExec. But I want to keep the main simple.

edit Noticed you're working with SWT

How can I get the "text" field from the actionEvent.getSource() ?

I have some sample code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.ArrayList;
public class JFrameTester{
     public static void main( String[] args ) {
          JFrame f = new JFrame("JFrame");
          f.setSize( 500, 500 );
          ArrayList < JButton > buttonsArr = new ArrayList < JButton > ();
          buttonsArr.add( new JButton( "first" ) );
          buttonsArr.add( new JButton( "second" ) );
          buttonsArr.add( new JButton( "third" ) );
          MyListener myListener = new MyListener();
          ( (JButton) buttonsArr.get( 0 ) ).addActionListener( myListener );
          ( (JButton) buttonsArr.get( 1 ) ).addActionListener( myListener );
          ( (JButton) buttonsArr.get( 2 ) ).addActionListener( myListener );
          JPanel panel = new JPanel();
          panel.add( buttonsArr.get( 0 ) );
          panel.add( buttonsArr.get( 1 ) );
          panel.add( buttonsArr.get( 2 ) );
          f.getContentPane().add( BorderLayout.CENTER, panel );
          f.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
          f.setVisible( true );
     public static class MyListener implements ActionListener{
          public MyListener() {}
          public void actionPerformed( ActionEvent e ) {
               System.out.println( "hi!! " + e.getSource() );
               // I need to know a title of the button (which was clicked)...
}The output of the code is something like this:
hi! javax.swing.JButton[,140,5,60x25,alignmentX=0.0,alignmentY=0.5,
border=javax.swing.plaf.BorderUIResource$CompoundBorderUIResource@1ebcda2d,
flags=296,maximumSize=,minimumSize=,preferredSize=,defaultIcon=,disabledIcon=,
disabledSelectedIcon=,margin=javax.swing.plaf.InsetsUIResource[top=2,left=14,bottom=2,
right=14],paintBorder=true,paintFocus=true,pressedIcon=,rolloverEnabled=true,
rolloverIcon=,rolloverSelectedIcon=,selectedIcon=,text=first,defaultCapable=true]
I need this: "first" (from this part: "text=first" of the output above).
Does anyone know how can I get the "text" field from the e.getSource() ?

System.out.println( "hi!! " + ( (JButton) e.getSource() ).getText() );I think the problem is solved..If your need is to know the text of the button, yes.
In a real-world application, no.
In a RW application, a typical need is merely to know the "logical role" of the button (i.e., the button that validates the form, regardless of whether its text is "OK" or "Save", "Go",...). Text tends to vary much more than the structure of the UI over time.
In this case you can get the source's name (+getName()+), which will be the name that you've set to the button at UI construction time. Or you can compare the source for equality with either button ( +if evt.getSource()==okButton) {...}+ ).
All in all, I think the best solution is: don't use the same ActionListener for more than one action (+i.e.+ don't add the same ActionListener to all your buttons, which leads to a big if-then-else series in your actionPerformed() ).
Eventually, if you're listening to a single button's actions, whose text change over time (e.g. "pause"/"resume" in a VCR bar), I still think it's a bad idea to rely on the text of the button - instead, this text corresponds to a logical state (resp. playing/paused), it is more maintainable to base your logic on the state - which is more resilient to the evolutions of the UI (e.g. if you happen to use 2 toggle buttons instead of one single play/pause button).

How to remove the automatically generated text fields from the InfoSet

I followed the procedure by SAP help.
Automatically generated text fields are marked with a 'T' on the icon in the InfoSet. You can remove the automatically generated text fields from the InfoSet in the initial screen of the InfoSet maintenance under Further Functions -> Delete Text Fields. Cancel the DataSource creation on the next screen and delete the text fields in the InfoSet maintenance transaction.
I know that there is an option "No automatic text recognition" when I create a new InfoSet, however, I couldn't find out how to change an existed InfoSet. I checked menu Goto->Global Properties, but that option is disabled. Is there a way to remove text fields from an existed InfoSet?

Hi,
In the initial screen (when you enter transaction code SQ02) type your infoset name and goto menu: Infoset -> More functions -> Delete text fields. this will delete all text fields.
I hope this helps to resolve the issue.

Remove text field from Array via for loop

Hi,
i have a problem to remove text fields added via for loop.
That im doing is, via for loop im dynamically creating menu with 10 buttons.
Each button contain, dynamically created, background (shape) and text field.
And everything is fine.
But when im try to remove text fields then i got this error:

Populating Multirecord text fields from Tlists value's combinations

I have a UI wherein there are two T lists, one on the Left and other on the Right. The left one contains
From values and the Right one contains To values. There's one Button which when Pressed should populate
a Data Block which has multi record text fields just below the button with all the possible combinations of
the T lists elements. The Text fields have the values From, To, Time, Unit. When populated From and Two will
get the values from the combinations and the user will enter the values in other fields i.e. Time and Unit,
Then the user can save the Records.
e.g. If the Left T list contains Red, Blue and the Right T List contains Green, Black. Then on pressing
the button below the T lists, the text fields From and Two of a data block displayed in the same window
should get populated with all the possible combinations as:
From || To || Unit || Time
Red Green
Red Black
Blue Green
Blue Black
Now the user can enter the values for Unit as well as Time and when he does save the Records should be inserted
for the Data Blocks DML Source that's some table.
What I'm trying is:
On pressing the Button i'm writing code that will have Two PL/SQL Tables(Index by binary_integer). One will have
all the values of the left T List and the other with all the values of right T List.
I do it as in the WHEN BUTTON PRESSED as:
DECLARE
TYPE varchar_table IS TABLE OF VARCHAR2(30) INDEX BY BINARY_INTEGER;
from varchar_table;
to varchar_table;
v_count1 NUMBER;
v_count2 NUMBER;
v_count3 NUMBER;
v_count4 NUMBER;
BEGIN
v_count1 := Get_List_Element_Count('CONTROL.FROM_TYPE');
     FOR i IN 1..v_count1 LOOP
          from(i) := Get_List_Element_Value('CONTROL.FROM_TYPE', i);
     END LOOP;
v_count2 := Get_List_Element_Count('CONTROL.TO_TYPE');
     FOR i IN 1..v_count2 LOOP
          to(i) := Get_List_Element_Value('CONTROL.TO_TYPE', i);
     END LOOP;
END;
Now how will I populate the text fields with the values in the tables that i got with the piece of code above.
Any help would be appreciated. Any other method other than the one i'm trying is also welcome. Please note that
i'm not using any table to store the elements in the T Lists. The lists get values at runtime by
user's selection.
Thanks,
Abhishek.

Try and stay civil in your postings. The solotion should be to simply issue a GO_BLOCK, followed by a CREATE_RECORD followed by setting the approriate values :block.value = <value from list>

Changes in the Text Field thru FB02

Hi,
I have created an accounting document thru FB01. However, there were some changes in the text field that needs to be done so I have edited the line items thru FB02. After saving the changes I viewed the data in tcode KE5Z but it seems that the changes in text were not captured in SAP Standard report. But when you double click the line item it will show the edited text.
For Example.
Document 1000001 original text is: 'Rental Charges for the month of April' ( originally created in FB01 )
Edited text thru FB02 : 'Rental Charges for the month of May'
In FB03, it will show the edited text which is 'Rental Charges for the month of May'
But in other reports such as KE5Z, it still shows the original text.
Kindly help.
Thanks.

Hi Sanil,
Thanks for the quick reply.
Is there a way where changes in an FI Document will also update the CO line items or the profit center actual line items?
When we originally create an FI document in FB01, the text field in CO line item is also updated as to whatever text we have inputted in the document ( details were stored in BSEG ). But if changes were made, the actual line items were not updated...
Regards.

Change display language of smartform from within the smartform itself

Hi!
The smartform is invoked to display from the standard with some language, which we want to change.
We can't change calling code (because it's standard).
Is it possible to change the displaying language of a smartform from within the smartform. Say, "Initialization" section?

Hi Concern,
We can change language at run time. With following way.
1.    Define a variable and allocate language u want to langu fields.
DATA lV_CT_PARA TYPE SSFCTRLOP.
Here LV_lang contain the language u want to assign.
LV_CT_PARA-LANGU = LV_LANG.
2. Pass it to smart form.
CALL FUNCTION FM_NAME
    EXPORTING
ARCHIVE_INDEX              =
ARCHIVE_INDEX_TAB          =
ARCHIVE_PARAMETERS         =
   CONTROL_PARAMETERS         = LV_CT_PARA
MAIL_APPL_OBJ              =
MAIL_RECIPIENT             =
MAIL_SENDER                =

Filtering responses in different text fields from different radio buttons.

Once again I need some guidance with my form please.
I have a form (audit report) with numerous radio buttons with 4 options each, NA, CN, PC and C.
Each represents a different answer to the question associated with the radio button.
This answer this then passes through to a text field next to the radio buttons.
In turn at the beginning of my form I have an executive brief giving a run down on findings from the different questions asked. These are a reflection of the text fields associated with the radio buttons.
These are represented as 2 text fields namely, Non-compliant (NC), partial – compliant (PC).
What I am getting now is a whole lot of “null” answers that change when one of the radio buttons are selected and reflects that answer associated with the selection, both NC and PC text fields are the same and I then have to edit it and delete the PC from the NC section and the same for the PC section.
What I would like to happen is that all the “nulls” are hidden and only when the answer representing the NC or PC buttons are selected, that those answer get represented through to the Non-compliant (NC), partial- compliant (PC) text fields in my executive brief. IE some sort of filter for each text filed that only displays the NC or PC answers.
Any help or guidance will be appreciated.

I will explain this through an example.
In my application I have created two Select Lists.
The first select list is a select list with a submit
P3_X allows selection of 1,2,3
The page branch sets the value of P3_X with &P3_X. so that way the second select list knows what value it will be using.
The second select list P3_Y is a dynamic query that says
Select SCOL d, SCOL r from TEST1 where FCOL=:P3_X
If you were to have a third select list you would make the second Select List also a submit and have the page branch also set P3_Y with &P3_Y.
The third Select list would say select from where item=:P3_Y
Does this answer your question?

Populating Text Field from Dropdown in Repeating Subforms

Hi there,
I'm trying to create a dropdown in a repeating subform that populates a text field in the same subform depending on the option selected.
I used the functionality described here to acheive the text field population in the first row, but I have trouble when I add additional instances of my subform. In subsequent instances, when I select an option from the dropdown, it changes the text in my first textbox and does not populate anything in the repeated textbox.
I'm not sure how to get this to work for each added instance and/or how to keep each instance separate from one another.
Thanks in advance for your help!

Can you repost the question - some funny formatting issue

Auto Populate Drop Down and Text Fields from Other Drop Down and Text Fields

Hi everyone
I'm trying to pre populate a "Proposed Employment Status" drop down field with the selection from the "Current Employment Status" drop down field and allowing users to select another option if the proposed employment has changed. If it hasn't it would just remain as populated by the Current Employment Status" entry.
I'm also trying to do this with text fields eg "Proposed Position Title" is populated with "Current Position Title". If the title changes in the bew employment arrangements users can enter it over the Proposed Position Title that is presented when the Current Position Title is entered.
I can get it to work if the drop down or text field names are the same, but this doesnt solve the problem.
Any ideas
Regards,
Michael

Java is a full featured-language and you shouldn't have any problem doing the mathematics, etc.
As far as the rest, Studio Creator is a relatively easy way to create the user interface that you describe. If supports drop-down selectable lists and standard form capabilities. A Web Application architecture would appear to be ideally suited to what you describe, and this is supported by SC. Be aware that this would require a server to serve the application to the client computer.
If the server is a problem you could consider an applet that would be downloaded from a website, and then run entirely on the client computer. But the first approach is better.

Pre-Populating Text fields from a Data drop down list using SQL Server

I'm currently trying to update some of our internal forms which are word based or a basic PDF form you fill in by yourself.
I'm connecting to our SQL server as there are databases stored there for an internal bit of software that hold information
I can use to fill in parts the form.
I have a data drop down list that is dynamically linked to the SQL databass and allows you to select a Project Number from that database, what
I want to do after this is selected is to automatically populate some text fields with the Project name, Account handler and other fields held in the
database.
I've had a look online to see if there is a solution but haven't really found anythig that is similar (although I am new to LC so may have seen it
and not realised) and my Java is non existant.
Has anyone tried this and able to point me in the right directions?
I'm using LiveCycle ES2 version 9.0.0.2 from Creative Suit 5.5 on Windows 7
Cheers

Hi,
Actually this error does not cause any harm except a presentation inconvenience. In my multi-select prompt I am using variable expression with dynamic repository variable. Dashboard results are correct. Just variable's value does not appear on page (error Error Codes: G689FFB3:SDKE4UTF
Expression: @{biServer.variables['CUR_CAL_PER_MONTH_NAME']}). Pushing "GO" button on the prompt fixing the error but it's actually second execution of the dashboard.
Any ideas ??

Is there a way to change an interactive text field back into a picture box?

I'm working on recreating an interactive form and I mistakenly made a picture box a text field when I should have turned it into a regular text box.
I can't seem to find a way to change it back.
All my boxes are lined up and sized perfectly right now, so I'd rather not have to re-draw the box and re-align and measure everything again if I can avoid it.

Select text field with Selection tool. Object > Interactive > Convert to Object. Place your picture into the frame.

Line item text field from MIGO are not copied into FI line item text field

Hi all on SCN, please, I need a help.
It was created as required by the user a field status group with the text field required.
This field status group was assigned to some accounts, in order to make my unit tests.
u2003
In development envirionment was made some tests directly in FI area, and it works properly.
u2003
But the user made a test using MIGO transaction, choosing in this transaction an account that he changed its field status variant to the one created in development environment, that make the text fiels required. So, to start, he donu2019t fill the text item of MIGO, and a message error appear stating that he needs to enter values in this field.
After fill in the text fiels, he can save his work.
u2003
But the FI document generated donu2019t receive the line item text typed in MIGO, but receives the values on Reference document and Document Header text entered in the header of MIGO, what is missing, donu2019t is automatically copied MIGO text line items to FI documents line Items, does there is some additional configuration missing?
Hope someone help me with this issues.
Thanks in advanced!

Hi,
Material document will get updated in reference field in FI by default. If for any reason, want to get this updated in text field, you need to define a subsititution in GGB1.
