Subject: Graphical mode synchronization
X-Git-Tag: v0.12.26~56
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=d26f04742e44ea6a45a5034a521c5948bc9361a4;p=lttv.git

Graphical mode synchronization

Hooks the trace synchronization code in lttvwindow. This allows to use trace
synchronization in graphical mode when lttv is started with the "--sync"
option. Unfortunately, the viewer interface "freezes" while the
synchronization code is running. This can take a noticeable amount of time
(more than a minute) for large traces.
