Hi folks,

I am working on a eclipse product where in I have to set the text in the about dialog.
I have about.ini, and about.mappings file.

I set the value of aboutText property but this is not reflected in the products About dialog.

Can any one tell me how does eclipse read this file???

Also when i tried giving the value of aboutText in plugin.xml it worked for me, but that is not the way I want.
I want it to happen by setting text in about.ini file.

Can any one help me???
JFace is defined by the Eclipse project as "a UI toolkit that provides helper classes for developing UI features that can be tedious to implement."[1] It is a layer that sits on top of the raw widget system, and provides classes for handling common UI programming tasks. It brings model view controller programming to the Standard Widget Toolkit.

You can find more info at : Jface Wikipedia

The UI creation is simplified by using Jface....internally Jface uses SWT widgets only...but JFace reduces the complexity of dealing with complex UI creation by providing helper classes.

And Yes SWT does provide many functionalityfor creating as complex UI as possible.

I think, this may help to you.!

Very good very good...
You cannot have final variables as case constants .......

Well in that case if someone tries cloning a singleton object then.......

In that case i think we should provide a clone method which throws a CloneNotSupportedExcption in our Singleton anyone if at all tries to clone the singleton oject.. would get a exception...and in this way tha object wont be cloned..

Hi I want to know whether we can have getter and setter for the discriminator column like the one below..

@DiscriminatorColumn(name="skill_type",discriminatorType=DiscriminatorType.STRING) //part of a class

The below are the classes extending above class......having discriminator values as shown.


Now this values are set as soon as you create a new object of the respective classes...

Now suppose from the UI i want to search a person by a skill type like above ones.....then how can i do it ..since i dont have a getter or setter for skill_type attribute..i think its not possible...and if its possible what is the way???

Can I know how do we make a entity variable skill_type ??
