Constructor Detail

TextViewer

public TextViewer(java.lang.String filePath,
                  java.lang.String fileName)
A basic viewer for disk based text files. This version is called by other than a Dialog or Frameobject. The constructor concatinates the filePath + fileName strings to form the full path\filename string which is used to load the text file. It's intended purpose is for viewing local disk based text files.

The viewer is non-modal so the user can scroll/read the contents while still working with the application program.

The filePath and fileName are displayed as the title of the viewer.

When building the filePath string, suggest using:

filePath = System.getProperty("user.dir") +"\\"; or

filePath = System.getProperty("user.dir") + System.getProperty("file.separator");

A valid path\filename would be C:\MicroMap\MicorMapLog.txt

Parameters:
filePath - The full path to the text file ending with a file seperator.

fileName - The full file name with a .txt extension

toString

public java.lang.String toString()
Returns the name of the class.

Overrides:
toString in class java.awt.Component
