I thought I finally figured out the Athena Text widgets and so I wrote
this short program which should act like an editor. It uses the
asciiDiskWidgetClass. However, the program will not let me input any
text from the keyboard. It just beeps at me. Any one have any helpful
hints?
I have compiled the following program on a sun3 and a sun4 (OS 4.0.3)
and ran it using the OpenWindows 1.0 beta2 window manager.
Feel free to modify it any way you like!
