public final class FillinTextField
extends TextField
This class is an AWT component that allows the GUI user to choose from a selection of text strings supplied by the program by typing in the beginning of the text string. The component will automatically fill in the rest of the string.
An instance is created by supplying the public constructor with an array of Strings specifying the valid entries that may be entered into the field, along with parameters specifying the initial contents and width of the field.
The component extends TextField, so all techniques used with that, such as registering ActionListeners, are valid.
getPosition() may be used to discover the currently selected String.
There are workarounds for the following flaws in the Symbian implementation of the JVM - these workarounds should not affect other platforms.
UP generates char code 9
DOWN generates char code 10
LEFT generates char code 7
RIGHT generates char code 8
