Ok now I hit a strange bottleneck. I hope anyone can help.
1. If I don’t delete the frame, tcl get sluggish like memory leak vibe
1a) I’ve tried
if {[info exists %lx_frame]} {.x%lx.c itemconfigure …
like I saw in the IEM - to no avail
2. If I delete everything in my draw routine (frame and points) I get happy, but
2a. My mouserelease binding disappears and doesn’t seem to accept rebinding.
I need that for the command-drag-to-zoom ending. During the drag it redraw all
right, so the “motion” still gets send, but my redraw deleting the frame on
which the original binding was done is delete and recreated and re-bind-ed but
to no avail
Now, I’m really stucked. I have tried everything.
Any help is really welcome.
