I have experienced some odd behavior with the text widget. I have a popup
dialog that contains a text widget. The purpose of this is to allow the user
to input a file name.If the user depresses the middle (2)  button in the
text widget when it is empty, then I popup a FileSelection widget. The user
then selects the file and I copy it to the text widget. Unfortunately, the
file selection box pops up twice. This is apparently once for the button 
down, and once for the button up. The documentation CLAIMS that the event
that caused the callback is put into the callback struct, but it is consistentlyzero. I would like to distinguish between button up and down, at this point
in the processing. Is the callback struct event pointer being zero just another
example of incorrect documentation, or is there some other setup necessary?
Any ideas out there?
Thanks in advance,
carl.
