adding items to listField

I am brand new to java and blackberry development. Everything I have done I've searched and found my answers but for some reason I cant find anything adding items to a fieldList.  I think Im suppose to use drawListRow but I can not get it set up correctly.  I have made the list and added it to the screen with:

 

ListField listField = new ListField(20);
add(listField);

 

I try to use drawListRow but I cant figure out the syntax.  Thanks for your help.

Re: adding items to listField

to draw the listfield you use the listrowcallback, seems you have this figured out correctly.

You have to implement the methods of the interface yourself.

 

drawListRow is similar to other paint methods, you have a low level access to graphics (which represents the area you can paint on). see the Graphics class for an overview of methods.

To get you started you can use drawText(string,x,y), with x = 5, y from the drawListRow parameters and string as the textual representation of your object.

 

The knowledge base has some samples of listfield usage:
