From: Tilman Sauerbeck Date: Sat, 7 Nov 2015 10:24:42 +0000 (+0100) Subject: Add TriggerMarker class. X-Git-Tag: pulseview-0.3.0~45 X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=51ae69ae74d4868e52785875daa5fa1360e638a6;p=pulseview.git Add TriggerMarker class. This will be used in a follow-up changeset for the markers that visualize the time of SR_DF_TRIGGER. Note that this copies a little code from the TimeMarker class, but that seemed a better idea than deriving from it and disabling the popup and label-drawing code. --- diff --git a/CMakeLists.txt b/CMakeLists.txt index 77b0137d..3bf7366d 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -206,6 +206,7 @@ set(pulseview_SOURCES pv/view/tracepalette.cpp pv/view/tracetreeitem.cpp pv/view/tracetreeitemowner.cpp + pv/view/triggermarker.cpp pv/view/view.cpp pv/view/viewitem.cpp pv/view/viewitemowner.cpp @@ -258,6 +259,7 @@ set(pulseview_HEADERS pv/view/trace.hpp pv/view/tracegroup.hpp pv/view/tracetreeitem.hpp + pv/view/triggermarker.hpp pv/view/view.hpp pv/view/viewitem.hpp pv/view/viewport.hpp diff --git a/pv/view/triggermarker.cpp b/pv/view/triggermarker.cpp new file mode 100644 index 00000000..f15672b5 --- /dev/null +++ b/pv/view/triggermarker.cpp @@ -0,0 +1,82 @@ +/* + * This file is part of the PulseView project. + * + * Copyright (C) 2014 Joel Holdsworth + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
