Setting a renderer for an entire table by default

Is there a way to set another renderer for an entire table, a renderer that extends DefaultTableCellRenderer in particular. I mean I can think of a workaround where I basically go through each column of the JTable and set the default renderer for each column, but that seems like a hack. Shouldn't there be away to set it across the board?
I don't see a Jtable.setCellRenderer(), I see ways of setting the renderer by Object type, or by column, but what about across the board?

table.setDefaultRenderer(Object.class, someRenderer);

Setting a renderer for an element dynamically at runtime

Currently i am searching for a UI feature : Generating a HTML table by setting the renderer for each cell dynamically at runtime. E.g. depending on some state dependency(e.g. authorization issue) i want to render information in a cell in one case as a hyperlink or a in the other case as a informational text (instead of the hyperlink).
My question : is that feature in JSF Framework implemented or adaptable? Viewing some JSP/JSF code, the definition of the renderer seems to me to be determined at compile time, and there is no example how to do as described above.
Any hint appreciated, Joerg

I agree with keyurva proposal. This rendererType is dynamically set based on the state.
2nd is if all the cell are the same component type, you even can extends the component to override the getRendererType() method making to returne a different value based on the state.

How to set the icon for the entire application with JFrame.setIconImage

I set the icon on the main frame using JFrame.setIconImage(). The icon is shown properly in the main frame.
If more JFrames are opened from the main frame, the newly opened JFrames also show the icon.
However if JDialogs are opended, in some cases the icon set on the main frame is shown and in other cases the coffee cup.
What is JFrame.setIconImage() expected to do? Setting the icon for a single JFrame or the entire application?
How can I set the icon for the entire application?
How can I set the icon for JDialogs?
Thank you

In order for your dialogs to use the same icon as the frame, you must parent the dialogs to the frame which has the custom icon.

How to set dbms_stats parameters for a single table

Hi,
I see that dbms_stats has the following procedure:
PROCEDURE SET_PARAM
Argument Name Type In/Out Default?
PNAME VARCHAR2 IN
PVAL VARCHAR2 IN
Is there a way to change the parameters only for a single table?
I need to set METHOD_OPT=>'FOR ALL COLUMNS SIZE 1' only for a specific table...

I'm sorry, mate. It looks like setting individual table preferences was introduced in 11g (and doesn't seem to work all that well).
You can still:
1. Explicitly specify any of the supported parameters by using DBMS_STATS.GATHER_TABLE_STATS() for the individual table and run it along.
2. Write a PL/SQL wrapper for let's say DBMS_STATS.GATHER_SCHEMA_STATS/GATHER_DTABASE_STATS that would gather the stats for the whole schema but ignore this particular table. Then gather the stats for the table with the METHOD_OPT parameter of your choice that could be different from the one used for the rest of the schema.
This could be achieved by locking particular table stats with DBMS_STATS.LOCK_TABLE_STATS, running GATHER_SCHEMA_STATS with force=>FALSE (which is the default). That parameter will make the procedure ignore any tables with locked stats. As the last step of the wrapper you can execute DBMS_STATS.GATHER_TABLE_STATS for the table in question with the desired METHOD_OPT and force=>TRUE.
It's a little more work, but may solve your problem.

Setting date format for the entire SQL Server installation - SQL Server 2008 R2-2012

Hi,
I need to safeguard the behaviour of SQL codes that inserting into SQL tables with some date columns. For this purpose, I need to change the date format for the SQL instance and not using CONVERT and CAST.
I've seen the SET DATE FORMAT statement, but if I use it, could I solve my problem?

The language setting is related to the database user.
BOL: "DEFAULT_LANGUAGE = { NONE | <lcid> | <language name> | <language alias> }
Specifies the default language for the new user. If a default language is specified for the user and the default language of the database is later changed, the users default language remains as specified.
If no default language is specified, the default language for the user will be the default language of the database. If the default language for the user is not specified and the default language of the database is later changed, the default
language of the user will change to the new default language for the database."
LINK: http://technet.microsoft.com/en-us/library/ms173463.aspx
The default language setting can be overridden by SET LANGUAGE for the session:
http://technet.microsoft.com/en-us/library/ms174398.aspx
Example:
SET LANGUAGE us_english; -- mdy
SELECT CAST ('12/13/2014' as DATE); -- 2014-12-13
GO
SET LANGUAGE british; -- dmy
SELECT CAST ('12/13/2014' as DATE);
GO
(1 row(s) affected)
Changed language setting to British.
Msg 241, Level 16, State 1, Line 2
Conversion failed when converting date and/or time from character string.

Setting a namespace for an entire message

Hello,
When creating a message type, it is possible to set a XML namespace for the message. But I observed that this namespace is only set for the root element an not for the entire message. The namespace is set like this in the resulting message:
<ns1:UpdateDictionaryItem xmlns:ns1 ="http://www.namespace.com">
        <District>
            <Name>SERV3</Name>
            <RegionParent>0001</RegionParent>
        </District>
</ns1:UpdateDictionaryItem>
But I would need it like this:
<ns1:UpdateDictionaryItem xmlns:ns1 ="http://www.namespace.com">
        <ns1:District>
            <ns1:Name>SERV3</ns1:Name>
            <ns1:RegionParent>0001</ns1:RegionParent>
        </ns1:District>
</ns1:UpdateDictionaryItem>
or like this:
<UpdateDictionaryItem xmlns ="http://www.namespace.com">
        <District>
            <Name>SERV3</Name>
            <RegionParent>0001</RegionParent>
        </District>
</:UpdateDictionaryItem>
Is there a way to do that?

How to set coumn value for an ADF Table?

Hi,
I am currently using Build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660. I have an ADF table in which I have a column created using View Object as Select one choice. I want to set the value(first time as selected one) in it which is coming from my second View Object. Can anyone please provide me sample code for the same?
Thanks,
Vik

Hi,
I have no idea what you are asking for. Did you try model driven List-of-Values defined for the attribute you want to update using a select one choice ? See this document http://www.oracle.com/technetwork/developer-tools/adf/learnmore/dec2010-otn-harvest-199274.pdf and look for how to create dependent list of values. Just follow the first part of it that explains how to create model driven LOV

Is there a wayto set a passcode on one's ipad e mail alone or do you have set a passcode for the entire i pad

is there a way to set a passcode on one's ipad e mail or do you have to lock the entire ipad?

You cannot passcode lock the mail app with any feature of the iOS.. There is an app that will let you passcode mail but I have no idea how well it works. You can check it out.
http://itunes.apple.com/us/app/mail-locker-keep-your-mail/id449844544?mt=8
If that doesn't work for you, then you have would have to passcode lock the iPad in order to prevent anyone from seeing your mail.

How to set runtime parameter for the entire system

Hi,
I have a problem with setting runtime parameters in jre v1.6.0_07. I have an XP computer with multiple users and to use the application eavery user must set the runtime parameter once by going to java control panel -> Java -> Java applet runtime settings -> view. How can i automate this? I have multiple users and there may be more users logging in so manually sending the C:\<userProfileDirectory>\Application Data\Sun\Java\Deployment\deployment.properties file to all profiles is not a solution. Same question here but no solution. Every user must get this parameter when they log in, they may be new users or existing users. The software I'm trying to use is browser based, we don't trigger an exe or something from local to run the software.
In C:\<userProfileDirectory>\Application Data\Sun\Java\Deployment\deployment.properties file there is a line like this;
deployment.javapi.jre.1.6.0_07.args=
This works for a single user. I've read the instructions in [deployment guide|http://java.sun.com/javase/6/docs/technotes/guides/deployment/deployment-guide/properties.html] but the properties file we put in C:\WINDOWS\Sun\Java\Deployment does not support ".args=" command. Anyone encountered or have a solution for this problem?
Thanks.

Hi,
got solution for this problem? I am also having the same problem.
Thanks.

How to set the indent for an entire paragraph without shortcut

I recently got told how to let the whole paragraph have an indent on the left side, just like the first line via Cmd+´(German version of InDesign). Is there also a menu command that does this? I don't like using shortcuts until I know what I'm actually doing. Is it true that the word spacing can only be done via shortcut? Is it the same here? What else is there, that can only be done via shortcut (and why)?
Thanks a lot!

You can set indents in the Paragraph palette. If you want a first line indent, like a normal paragraph in a book or magazine, just change the First Line Indent. If you want a hanging indent, like on a bulleted list, then set the Left Indent first then make the First Line Indent a negative value.

How to set title/text for ALV table column header in WD ABAP

Hello,
I am working in WDA using SALV_WD_Table to display data in table. I need to change the column header text, the obvious way is to get the column header and call the method SET_TEXT to set new text / title. However, this method does NOT work, it does not change the column header text. I also tried the SET_TOOLTIP, this one works, but SET_TEXT does not work. Anyone has idea why this not working and do you find any go-around solution?
My version is NW 7.0
Thank
Jayson

Hi jason ,
For setting Heder text for your ALV table
ip_confing type ref to CL_SALV_WD_CONFIG_TABLE.
"set alv table header
ip_config->if_salv_wd_table_settings~r_header->set_text( 'Test ALV Header functionality' ).
first you have to hide the DDIC text and then try to set your own text .
"modify columns
LOOP AT lt_columns INTO ls_column.
    lr_column = ls_column-r_column.
    CASE ls_column-id.
      WHEN 'MANDT'.
        "hide this field
        lr_column->set_visible( cl_wd_abstr_table_column=>e_visible-none ).
       WHEN 'SEQNR'.
        "set header to different string
        lr_column->r_header->set_ddic_binding_field( if_salv_wd_c_column_settings=>ddic_bind_none )." use this line to hide ddic text
        lr_column->r_header->set_text( 'Position' ).
    endcase.
endloop.

How do I set proxy settings for a Java app behind a corporate server?

Thank you for the quick reply! But the solution provided by you, it seems, has still not been able to address my issue. I ran the program at command prompt with your said parameters, but the download still gave an error in the App window.
Also, is there some way of defining these parameters in the source code? I am keen in using NetBeans to run the program.
Cheers!

How to set plain-text for outgoing messages?

I just upgraded from a Pre "minus" to a Pre 2 with WebOS 2.1 . I now have mail recipients complaining that my messages are in HTML. How to I revert to plain-text for sending messages?
Post relates to: Pre p100eww (Sprint)

Hi jason ,
For setting Heder text for your ALV table
ip_confing type ref to CL_SALV_WD_CONFIG_TABLE.
"set alv table header
ip_config->if_salv_wd_table_settings~r_header->set_text( 'Test ALV Header functionality' ).
first you have to hide the DDIC text and then try to set your own text .
"modify columns
LOOP AT lt_columns INTO ls_column.
    lr_column = ls_column-r_column.
    CASE ls_column-id.
      WHEN 'MANDT'.
        "hide this field
        lr_column->set_visible( cl_wd_abstr_table_column=>e_visible-none ).
       WHEN 'SEQNR'.
        "set header to different string
        lr_column->r_header->set_ddic_binding_field( if_salv_wd_c_column_settings=>ddic_bind_none )." use this line to hide ddic text
        lr_column->r_header->set_text( 'Position' ).
    endcase.
endloop.

How to override the renderer for ADF component?

I want to overide the renderer for ADF components, without using <default-render-kit>, I defined every render class. But It does not work.
Always told me: Could not find renderer for CoreOutputText[UIXFacesBeanImpl, id=_id0], rendererType = oracle.adf.Text
How can I config custom renderer for exsiting component or new components?
Thanks a lot!
<render-kit>
<render-kit-id>oracle.adf.core</render-kit-id>
<renderer>
<component-family>oracle.adf.Output</component-family>

</renderer>

<renderer-type>oracle.adf.Group</renderer-type>
<renderer-class>oracle.adfinternal.view.faces.renderkit.core.xhtml.PanelGroupRenderer</renderer-class>
</renderer>
</render-kit>

Seems I need override the encodeSelectItem() method.
But not sure which class is the renderer for af:selectManyCheckbox. And how to set below
<component-family>???</component-family>
<renderer-type>???</renderer-type>
