Stereo Question-GLwMDrawingArea

Post by isla » Fri, 20 Nov 1998 04:00:00

I have a program which exits with the following error:

 Error: GLwMDrawingArea: requested visual not supported

when it goes into stereo mode. does anybody know if this
error is due to missing harware or software. I thought a
standard O2 did not require additional hardware to display
stereo (via emmiter/glasses).

The systems is O2 running Irix 6.3. Hinv gives

1. RapidApp, GLwMDrawingArea question


This is the scenario:
I have an application that I am using RapidApp to develop. I have a
control panel process(CP), and a Screen process(SC). The process CP
writes into a shared memory segment the value of a dial. SC is supposed
to poll the shared memory segment to see if the dial value has changed,
read the value of the dial from the shared memory and based on its
value, perform an operation on an image (eg., convolution), and draw the
resultant image on the screen (a GLwMDrawingArea).

This is my problem:
The GLwMDrawingArea widget created using RapidApp can only be accesses
using the callback functions (expose, input and resize). Is there a way
I can make it respond to a custom event like the change of the value of
the dial?
