Subject: MainBar: Only show "total sampling time" tooltip if supported by device.
X-Git-Url: http://git.code-monkey.de/?p=pulseview.git;a=commitdiff_plain;h=4a8185876c7d4dcb0e940df3077f46c0c98de7f9

MainBar: Only show "total sampling time" tooltip if supported by device.

If the device doesn't support SR_CONF_LIMIT_SAMPLES, the tooltip would
always show a sampling time of 0s.
