Subject: View: support multiple trigger markers in one acquisition.
X-Git-Tag: pulseview-0.3.0~42
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=92ff2b60d60c8191a6f4a923b5a9099ec544adbd;p=pulseview.git

View: support multiple trigger markers in one acquisition.

Remove the previous acquisition's markers when a new acquisition
is started, and add a new one everytime we receive the SR_DF_TRIGGER
packet.
