Summary: kst with multiple tabs is slow
AssignedTo: kst kde org
ReportedBy: matt truch net
Version: 1.1.0_dr1 (using KDE KDE 3.3.2)
If I create a window with multiple tabs, kst will be as slow as if each tab was opened in its own kst instance. kst should instead do the minimum work required to display the info only in the visible tab(s). All hidden tabs (or windows or whatever) should do no more than possibly keeping the vectors up to date with live data (if applicable). They should definatly not do things like calculate hidden PSDs or other CPU intensive tasks.
This is most prevalent when we are plotting BLAST detectors. Imagine 8 (or more) tabs, each has either 24 curves on 24 plots at 100Hz for 500 points, or 24 curves on 3 plots on the left column with corresponding psds on the right.
