The mouseMove handler would have the form selected. Perhaps you need to
select the form, and glselect the isigraph, inside your timer?
paint_base_ ''
is the preferable way to change locales.

Hello. I’ve got a timer firing a callback routine (in the z locale, of course)
that in turn needs to call a paint routine in the base locale. I’ve tried
sys_timer_z_ =: 3 : 0
cocurrent <‘base'
paint ‘'
)
…as well as
sys_timer_z_ =: 3 : 0
paint_base_ ''
)
Both work, actually, in that they call paint…except:
The paint routine makes a series of gl2 calls. All of them work, too. The
only problem is that the first gl2 call (it doesn’t seem to matter what gl2
routine is being called) prints:
|domain error: chkgl2
| glfill 255 255 255 255
…to the terminal. (In this case, the first call was to glfill.). This would
not be a serious problem except that I’m doing animation and shooting for 30
fps. Flooding the terminal with spurious gl2 errors will make other debug
output difficult to find.
Note that I call the same paint routine from a mouseMove event handler (interim
solution)—in which case no gl2 error message is printed. That’s why I wonder
about locales and the timer.
Am I missing something obvious?
Thanks.
