dynamic controls

[Former Member]

hi ,

u have given about dynamic text creating in webdynpro but i am confusing .

in src package we are placing SomeBackend.java file that file having information about user interface elements

The following is the coding in .java file

-

---

private Object[] fields ={new FieldDescriptor("InputField","first","com.sap.dictionary.string","First Name","enter first name",""),

new FieldDescriptor("InputField","last","com.sap.dictionary.string","Last Name","enter Last name",""),

new FieldDescriptor("InputField","birth","com.sap.dictionary.date","Date of Birth","enter date name",null),

new FieldDescriptor("DropDownByKey","country","com.sap.workshop.dynamicprogramming.simpletypes.Country","country","choose sex",""),

new FieldDescriptor("RadioButtonGroupByKey","first","com.sap.dictionary.string","First Name","enter first name",""),

new FieldDescriptor("CheckBox","isManager","com.sap.dictionary.string","First Name","enter first name",new Boolean(false))

};

-

---

THE ABOVE I AM TYPING IN .JAVA FILE I AM GETTING ERRORS

FieldDescriptor cannot be resolved

PLZ GIVE ME THAT .JAVA FILE FULLCODE I WANT

IN THAT U ARE USING INNER CLASS JUST U ARE GIVING Object[]

how can i declare FieldDescriptor in SomeBackEnd.java file

i am waiting for complete .java file

jagadeesh,

seems that you are using one of WD tutorials, just download files that accompanied this tutorial -- FieldDescriptor class should be there, it is not standard WD class.

Hi Jagadeesh,

I guess u need to create FieldDescriptor.java file.

public class FieldDescriptor

{

String field1,field2......;

public FieldDescriptor(String f1, String f2, String ....)

{

this.field1 = f1;

...

...

}

}

U might find this tutorial to be confusing but u should more concentrate on the dynamic creation of UIEs rather than these .java files. Try to learn the basics like:

how to create UI dynamically,

how to create value nodes, attributes etc,

how to map them to UIEs etc.

how to create and map action etc.

better u think of ur own scenario(Eg: a simple TextView UIE showing ur details etc) and try to create them dynamically.

regards,

Piyush.
