But my application sometime doing expected behavior and sometime fails.Almost certainly a concurrency issue. Are you aware of Swing's single threaded rule, and have you taken care to create and update all Swing components on the EDT?

How to set a Swing component as Modal window on a SWT Component.?

How to set a Swing component as Modal on a SWT Component.I mean, I have a window (SWT Container) with some menu items.
When I click on one menu item then i will get one new Swing Window.
When creating the new frame I had passed Modal value as TRUE in the constructer.Now child is not behaving as Modal Window.I mean I am able to go to parent window even though the child window is opened as a Modal Window.This is only happened when I double click on the Title Bar of the Parent Window.
If I try to click on any other part of the Parent Window except Title bar ... the child window is working as a Modal Window.
Can any one suggest me to solve this one !!

int this case, do this :
JFrame f = new JFrame("Authentification");
f.getContentPane().setLayout(new BorderLayout());
f.getContentPane().add(myJPanel, BorderLayout.CENTER);
f.setBounds(x,y,w,h);
f.setVisible(true);
Where myJPanel is the Panel you developped.

Hallo Praveen,
have you controlled that id of the Linktoaction ? there you made error.
See it in the ViewElement designer .
should be something like this
lr_elem = view->get_element( 'LTA_name ' ).

How to set focus to required component in the application

Hi all,
Based on user events, I want to set focus dynamically to required component/panel in the application.
Is this possible? is yes, pls give me api for that!

[http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/JComponent.html#requestFocusInWindow()]
A panel is not focusable by default.
If you want a panel to get the focus you have to use panel.setFocusable(true) first.

How to set focus and mark red on certain select option field

hi experts
I embedded a select_option view in my application and tried to use IF_WD_SELECT_OPTIONS->request_focus to set focus on a certain select option field if the logical check failed, and also hope the low field of the select option can be marked red....but things does not happen that way....
could anyone kindly tell me how to implement that requirement?
tkx and regards
sun

What is the problem you are facing in this ?
Requesting focus is easy.
just call the method request focus and pass the id of the parameter whose lower value field you want to focus.
as shown below.
code you might have written in wddoinit
DATA: LT_RANGE_TABLE TYPE REF TO DATA,
        RT_RANGE_TABLE TYPE REF TO DATA,
        READ_ONLY TYPE ABAP_BOOL,
        TYPENAME TYPE STRING.
    DATA: LR_COMPONENTCONTROLLER TYPE REF TO IG_COMPONENTCONTROLLER,
        L_REF_CMP_USAGE TYPE REF TO IF_WD_COMPONENT_USAGE.
*   * create the used component
L_REF_CMP_USAGE = WD_THIS->WD_CPUSE_SELECT_OPTIONS( ).
IF L_REF_CMP_USAGE->HAS_ACTIVE_COMPONENT( ) IS INITIAL.
    L_REF_CMP_USAGE->CREATE_COMPONENT( ).
ENDIF.
    WD_THIS->M_WD_SELECT_OPTIONS = WD_THIS->WD_CPIFC_SELECT_OPTIONS( ).
    WD_THIS->M_HANDLER = WD_THIS->M_WD_SELECT_OPTIONS->INIT_SELECTION_SCREEN( ).
LT_RANGE_TABLE = WD_THIS->M_HANDLER->CREATE_RANGE_TABLE( I_TYPENAME = 'ZDEALERID' ).
* * add a new field to the selection
WD_THIS->M_HANDLER->ADD_SELECTION_FIELD( I_ID = 'ID'
IT_RESULT = LT_RANGE_TABLE I_READ_ONLY = READ_ONLY ).
code for focusing a field.
wd_this->m_handler->request_focus( i_id = 'ID' ).
you must have declared attributes m_handler and m_wd_select_options type reffering to IF_WD_SELECT_OPTIONS and
IWCI_WDR_SELECT_OPTIONS respectively.
and regarding that red color i am not sure it is possible without using message manager.
thanks

How to set focus on a input field in a selected row of a table?

In a previous discussion (http://scn.sap.com/thread/3564789) I asked how to access an input (sap.m.Input) field of a selected row in a table. In the answer that was supplied I was shown how to get the items of the table. Then using the selected index to get the selected item get the cells. Then I could set editable on the proper cell(s). This worked fine.
Now I need to set the focus on one of the fields. I tried something like this:
            var oNewLink = table.getSelectedItem();
            var oNewLinkName = oNewLink.getCells()[1];
            oNewLinkName.focus();
But this doesn't seem to work.
I have searched through other discussions and have seen this technique for putting focus on a field if you have its ID:
sap.ui.getCore().byId(id_of_the_input_field).$().focus();
In my case though I do not have an ID since the row and its cells are generated. How can I set focus on the cell of a certain row in a table?

Hello Venkatesh. Yes that code does work. First I tried it on a table cell that was already rendered and it did work. The next time I tried it on a table row that was being added and it did not work there. So I added an on after rendering function for the table and added that code there. That did not work until I added a delay (timeout) to do a context switch before calling the focus and that worked.
Once last thing though sometimes when I call focus on an input field (actually in a table row cell) if the field has text in it already the flashing cursor is at the beginning of the text and other times it is at the end of the text (which is the desired way). It depends on where I click in the row. Is there anyway to make sure the flashing cursor is at the end of the text when the focus is applied to a field that contains text?

How to set focus on the title of JTabbedPane

I have created a JTabbedPane and added three JPanels to it. They are titled, say "Panel 1", "Panel 2" and "Panel 3". And each of them contains buttons and text areas. Since this app is for physically disabled users, it must provide navigation through these three tabs with keyboard operations only (i.e. without mouse clicks).
When the title "Panel 1" gets focused, users can go to "Panel 2" by the right arrow key. When Panel 2 is brought up, however, the title "Panel 2" does not get focused. Instead the first button inside panel 2 is focused. In order for users to navigate to 'Panel 3" by the arrow key, the title "Panel 2" has to be focused. How do I set focus on the tab title?
I have tried 'requestFocus()' on Panel 2, but it does not work. Please help me with this issue. Thanks in advance.

I'd be quite interested to know if this can be doen as well so I thought I'd post this message to move it to the top of the board.
Thanks.

How to set focus on invisible input field?

Hi Guys,
I need an invisible input field and have to set an input focus on it. My problem is that if I set input fields property visible=blank, I get my invisible field <b>BUT</b> the function call doesnt work (setInput.requestFocus()).
I suppose that I cant set a focus if an input field is invisible.
Does somebody know how can I solve my problem? Is there a possibility to do this input field invisible with java script? If yes, how does it work in Web Dynpro?
Thanks
Marita

Hi
Setting a focus on invisible input field will not work even if you follow the method what sowjanya has suggested. The method wdThis.wdGetAPI().requestFocus() will not work for read-only and disabled fields.
By the way why do you want to set the focus on a invisible input field. If you can tell us the requirement maybe we could think of an alternate solution. But i guess for the current scenario setting focus on invisible input field does not work.

ravi
