[RBASE-L] - Re: RECALC causing all images to blink

[Michael J. Sinclair, MD]

Larry,

Is there a way with the current options to allow Rbase to redisplay/repaint a single object without "repainting" all objects?

The challenge in being able to recalc just one variable is what to do about dependent variables?

The problem here isn't actually in recalculation, as far as I can tell.  All the actual calculations are done in the EEPs and Marc says he has no actual variable expressions defined in the form.

The problem is that if you recalculate variables in your EEP code, R:Base apparently does not know that it must update the on-screen representation of those variables.  Therefore, you have to use RECALC VARIABLES which seems to include an implicit repaint of the entire form.  Ideally, R:Base would either know that updated variables need to get repainted (although there's a problem with this too — if your variable changes through a lot of intermediate values during an EEP run, it could cause odd blinking) or else there would be a PROPERTY ComponentID REPAINT 'TRUE' command that would update the form with the variables current contents.
