A long long time ago I had a scroll region in a gtk app. However, it turned out that the scroll region was limited to something like 32K or 64K pixels. Evidently it was limiting pixel counts to 16-bit words. I could not find this limit in any user documentation. I have since asked about such limits in newer versions of gtk. I have never received a reply. Be careful. You might hit such limits, and your interfaces might behave in dangerous ways. -- hendrik -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
