Question

I am having one flow field manager added on screen & in that manager i had added some custom fields.now if i want to change data on particular field only how should i invalidate that particular field?

Answer 1

you can edit the custom field to invalidate itself. Say you want to set the text in the customfield. You do

field.setText("Test");

setText should be

public void setText(String text)
{
this.text=text;
invalidate();
}

In this way, you can invalidate just the customfield, and only it will be repainted
