inherting classes avalibile i jar

[ciju madathil]

Hi all,

i want to extend the VTextField(basic Forms text item) to implement the functionality (like invalidcharacters, grouping characters in a string like 22-333-444 etc)of javax.swing.text.MaskFormatter.
Can anyone please help me achving this.
Since Java class cannot extend 2 classes.
solution for multiple inheritance is implementing interfaces but since the classes are already present in jar(oracle.forms.ui.VTextField and javax.swing.text.MaskFormatter)
how can i achive this.

Please help me.

Thanks and Regards,
Ciju George

Try composition - give the text field a formatter as a field with a getter for it.

@Rob I doubt whether it would work
