Cannot see duration between t1 and t2 in Control Flow [message #1719540] Fri, 08 January 2016 17:39 Go to next message

When opening an lttng kernel trace, in the Control Flow window, I would like to see the duration of the shaded zone as described in the documentation :
"The vertical blue line with T1 above it is the current selection indicator. When a time range is selected, the region between the begin and end time of the selection will be shaded and two lines with T1 and T2 above will be displayed. The time stamps corresponding to T1, T2 and their delta are shown in the status line when the mouse is hovering over the control flow."

But when hovering over the control flow, I only get the duration of the current event pointed by the mouse cursor and the full duration of the trace when no an event is not active.

Does anybody know how to fix that or to get the duration of the shaded zone?

(This was answered in IRC, but for reference I will repeat the answer here in case other people hit the same problem.)

The information about the currently-selected time range shows up in the status bar, completely at the bottom of the window. It is present in your screenshot, but barely visible due to what seems to be a theming issue. It could be due to a misbehaviour between SWT and the new GTK 3.18.

You could check if using another GTK theme fixes the problem, or you could switch to GTK 2 by launching Eclispe (or the Trace Compass RCP) with "SWT_GTK3=0".
