Problem in setting focus in JTable

Hi,
In my application I am using JTable with a customized table model. The table has two columns. First column has jcombobox as its editor and the second column has the customized editor developed by me. This particular table appears in a wizard. When this wizard page (which contains the above JTable) is shown I set the keyboard focus on the JTable using JTable's requestFocus() method (I even tried with grabFocus()method but got the same result). But the focus does not appear on the JTable. Even none of the cells get the focus. Also no matter how many time I press tab key the focus does not shift to the next component in the page which happens to be a JButton. I have set the next focussable element for the JTable as that JButton. When I manually put the focus on one of the cells by clicking on it and then if I press either arrow key or tab key the focus is lost and it does not go either on the next cell or the JButton.
If anybody can shed some light on what exactly needs to be done to give proper keyboard navigation for JTable please let me know.

Hi Atul,
I suspect your problem is with your cell renderer. The DefaultTableCellRenderer class has code in the getTableCellRendererComponent method that provides the visual indication as to which cell has the focus. You will want to do something similar in your JPanel-subclassed renderer - perhaps change the border or the background color to indicate whether a cell is selected or not.
Note also that there is a difference between a cell that has "isSelected" set to true, which indicates that the cell is part of the current selection, and a cell that has "hasFocus" set to true, which indicates that the cell is the last one to be clicked on. Actually, it seems to be a bit more complicated than that, but that's at least part of what "hasFocus" indicates. A cell can be selected and not have the focus, and a cell can have the focus but not be selected. You may want to setup your renderer to clearly indicate which of these states are set and then run your app and play with the table selection to get a feel for how it works.
Hope that helps.

(URGENT) problem with JTable: can't catch ENTER and control focus in JTable

I hava a JTable and a AbstractTableModel.
Here is what i want to DO.
When I press the ENTER or TAB I want to set focus to cell wich is 2 position away from the the sell I am editing
on the same row in the JTable. How can I do this.
in fact, that is my real question HOW to ?
When I press the ENTER or TAB in JTABLE I want to tell to JTable which cell to grab the focus

In the UI is defined the InputMap/ActionMap pair to respond to keys. There is defined an action for ENTER. I have had the same problem, and the only thing that worked for me was to clear the actionMap, and reassign some keys to their original action, and some (e.g. ENTER, TAB) to my actions. This worked. With TAB is harder beacuse i guess it's deeper in the JVM implemented, but after a while i've managed to overwrite that too.

Setting Focus

On window startup/popup, how do I set focus onto the first row of a table? I've tried using the both the requestFocus and grabFocus methods, but neither seems to be working? Is there something else I must do first before requesting focus?
I basically instantiate my JTable with JTable table = new JTable(rows, colNames) then say table.grabFocus() or table.requestFocus. When the window pops up, focus still defaults to the first object in the JFrame :(

That's it. I have j2sdk1.4.2 but still need to set visible before setting focus. I'll try the addComponentListener method as well just for fun.
Thanks

Setting focus on a component from backing bean

Is there an easy way to set focus in a specific component on the jspx from a method in the backing bean? (other than javaScript coding...)

Hi,
did you take a look at
About control the cursor position in a JSF web page
It contains some links to other weblogs. The links are helpfull. Maybe you'll be able to find your solution there......
Good luck

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 a custom PO Item screen field when in error?

Hi All,
I have an interesting situation that i'm wondering if others have solved. We have extended the PO item table (EKPO) by adding two new fields. We then have implemented two BAdI's: ME_GUI_PO_CUST and ME_PROCESS_PO_CUST to add them to the ME21N/ME22N/ME23N screens and logic to do some validation, via these respective BAdI's mentioned. Everything works perfectly - with one small issue. When we are doing some validation via a method on the ME_PROCESS_PO_CUST - and "invalidate" the field (and throw an error) when it is in error - I also want to be able to "set focus" on the field in question (basically: go to the particular tab on the ME* screen and highlight the field). I have tried using SET CURSOR FIELD ***** within this BAdI (ME_PROCESS_PO_CUST) - but doesn't seem to work. Has anyone tried to do this and have come up with a solution? Would be much appreciative if you shared it!!! Thanks much.
Cheers,
Matt

Back again - set focus

Hi again,
I've been struggling with setting focus on each instance of a field within a repeating subform. My subform is limited to 5 instances. Min of 1.
As the user exits the only textfield in the subform, I have a new instance creating. I want the focus set to the new instance but I have not been able to get anything to work. My latest attempt has been to try to pass a count using the instancemanager to a variable in the setfocus string.
Here is what I have thus far. I know I need to resolve the node but that process is confusing the heck out of me. I've read and re-read everything I've been able to find but I havent been able to wrap my head around that part successfully.
Can anyone point me in the correct direction or suggest a better solutions? TIA!
form1.Account_Client_Information.Long_Title.Account_Long_Title::exit - (JavaScript, client)
var oSubform = xfa.resolveNode("Long_Title");
var oNewInstance = oSubform.instanceManager.addInstance(1);
xfa.form.recalculate(1);
var count = (this.instanceManager.count)
xfa.host.messageBox("Text Field Index in new Subform: " + count);
var vfocindex = xfa.resolveNode("Account_Long_Title[count]");
xfa.host.setFocus(vfocindex);

Hi,
The addInstance method will return the subform that you want so you only need to do;
var oNewInstance = Subform1.instanceManager.addInstance(1);
xfa.host.setFocus(oNewInstance.Account_Long_Title)

How to set focus in text box at server side

Hi,
I have small problem , i have a text box in form , which is get validated at server side in servlet , if it found some thing wrong then it throws exception , i want that when an exception is thrown it should set focus for that perticular text box. so what should i write to perform such a activity.

Get hold of the element ID in the servlet (and keep the code conventions) and print it out to some Javascript function which does a focus during the onload.
There's an example of focus/highlight using JSP/Servlet/Javascript in this article: [http://balusc.blogspot.com/2008/07/dao-tutorial-use-in-jspservlet.html]. Also see the screenshots at the very bottom.

Setting focus in a PDF form

Hi,
I'm trying to move a cursor to a particular field based on certain conditions using JavaScript. The method I am using is xfa.host.setFocus("fldTest"); in the initialize event. For some reason the focus isn't getting set to fldTest, but when I first hit tab it goes into the first field that is in the tab order. Is there any way around this?
Thanks,
Chad

You might want to check the reference path of the field that you want to set focus on.
Ex: xfa.host.setFocus("form1.page1.subform1.TextField1");

Setting focus to new instance of a field...need help.

Hi there,
I have a flowed form which consists of multiple subforms. I have one subform which is basically one textfield that is set to a min of 1 and a max of 5.
These are to correspond to fields in our system of record that have 5 fields for company long name with a 36 character field limit.
I've got the limits set up just fine and I have added simple script to add a new instance when the user exits the field.
The focus goes to the next field set in the tab order but what I want is the focus set on the new instance of field created but I have not been able to find an example of how to do that.
Any suggestions would be greatly appreciated. Thanks!

Well,
I've been reading and trying various things but cant get anything to work like I want it to.
The sample provided works for 2 iterations but mine has to do this for up to 5 instances. I have not been able to figure out how to get this to work.
Anyone have any additional suggestions?
btw...here is my modified version. ES2 is whay I'm using.
Long_Title.occur.max = "5";
var oSubform = xfa.resolveNode("Long_Title");
var oNewInstance = oSubform.instanceManager.addInstance(1); // I think you probably managed this first part better than here
xfa.form.recalculate(1); // I THINK THIS IS IMPORTANT
var count = (this.Long_Title.nodes.length)
var testIndex = oNewInstance.Account_Long_Title.index;
xfa.host.messageBox("Text Field Index in new Subform: " + count); // TextField1 will conserve index 0 because it is the only textfield in the new Sub1
var NEW_TEXTFIELD = xfa.resolveNode("Long_Title[1].Account_Long_Title[0]"); // However, Sub1 gets index 1 because it is not alone any more
xfa.host.setFocus(NEW_TEXTFIELD); // This actually sets focus on the newly created instance of TextField1 (actually Sub1 instance)

Setting Focus In Textarea

Ok,
I have a java program I've bundled into a jar and then packaged into a Win32 executable. I have windows associate a particular filetype (.wri) to my program.
When I click a .wri file and open it, it loads data to a textarea. Now when I scroll down the textarea and finally click in the textarea, it resets me to the top of the textarea. Now, if I open the executable first, then go through the program to open a .wri file, I can scroll down to the bottom of the textarea, click in the textarea and I do not get reset to the beginning. I need a way to prevent the resetting of the textarea. I've tried using some of the Window methods for setting Focus, but none seem to work. Any ideas why this is happening via the one way and not the other. I'm open to any ideas. This known bug frustrates many because the .wri files being opened have over 1000 lines of text. Thanks in advance!

i think yu can use setFocus by using lostFocus event.
use Focuslost()
