Chet Haase and Romain Guy have just published a book about "Developing animated and graphical effects for Java applications".
I have not read it yet, but, knowing the reputation of these guys, I am sure that it is most certainly a gold mine for every Swing developer.

Here is a Java bean that allows the Drag 'n Drop within a Swing JTree item.
This bean is proposed by Minas Lyrakis from Greece.
This bean uses itself the DispatchingBean of Tom Cleymans. (so it needs the sun Java plugin 1.4 at least)
You can Drag 'n Drop nodes within the same tree but also from one tree to another as well.

Here is a package that allows the dispatching of events from Java Beans to Forms on Beans that extend VBean, beans that use the FBean package and also PJCs !
No, you are not dreaming and there is no mist on your glasses, a PJC that dispatch event to the form module !
 |
You know that a Bean that extends VButton or VTextField for example cannot use the dispatchCustomEvent() method to send message to Forms, so how could this be possible ?
Tom Cleymans from Belgium brings here the solution.
He decided to attach a class that extends VBean to each PJC, so that it can use the included dispatchCustomEvent() method to send messages to the corresponding Forms' module Bean Area.
As brilliant as simple !
Read the Tom's article then do what you are searching for years . |

I have provided several PJC/Beans that use the Java gradient to colorize some objects.
Someone asked to me if it could be possible to apply this gradient feature to the whole Forms canevas.
So here is a Java Bean that allows to paint the current canevas with a Java gradient.
It needs the JRE 1.4 (Sun Java Plug-in)

Here is a Swing JButton that overloads a standard PJC's button.
It allows to have a standard Forms button with some nice decoration features.
You can apply a gradient color, set rounded borders, justify the label and also have a shadow behind the label.
Because it is firstly a PJC, you can set most of the common properties with the Set_Item_Property() built-in (label, position, foreground color, background color, etc...).

I was asked to build a JSP page within our Portal application to show some employee's characteristics.
It is easy to get all the common attributes with the search() method, but I never found anything to get the photo. Maybe this kind of function exists but I never found it.
So I decided to search where this binary file was stored.
Actually, it is stored in the ODS.DS_BATTRSTORE table:
CREATE TABLE DS_BATTRSTORE
(
ENTRYID NUMBER NOT NULL,
ATTRNAME VARCHAR2(255 BYTE) NULL,
ATTRVAL BLOB NULL,
ATTRHASHVAL VARCHAR2(4000 BYTE) NULL
) |
The ENTRYID contains the internal number, the ATTRNAME contains in this case the constant ‘jpegphoto’ and the image is stored in the ATTRVAL column.
So, if you know the employee number, you can extract his/her photo with the following query:
SELECT
attrval
FROM
DS_BATTRSTORE bs
WHERE
bs.attrname = 'jpegphoto'
AND EXISTS
(
SELECT 'x' FROM CT_EMPLOYEENUMBER ct
WHERE ct.entryid = bs.entryid AND ct.attrvalue = 'employee_number'
)
; |
