From: Jens Steinhauser Date: Fri, 23 May 2014 19:36:54 +0000 (+0200) Subject: Use a separate widget to hold the cursor labels. X-Git-Tag: pulseview-0.3.0~604 X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=84a0d458a4b04141dd45af6dec44d36782ee163e;p=pulseview.git Use a separate widget to hold the cursor labels. This way the cursor labels don't overlap with the ruler. --- diff --git a/CMakeLists.txt b/CMakeLists.txt index 5c66e4e6..a6c0445b 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -135,6 +135,7 @@ set(pulseview_SOURCES pv/toolbars/samplingbar.cpp pv/view/analogsignal.cpp pv/view/cursor.cpp + pv/view/cursorheader.cpp pv/view/cursorpair.cpp pv/view/header.cpp pv/view/marginwidget.cpp @@ -174,6 +175,7 @@ set(pulseview_HEADERS pv/prop/string.h pv/toolbars/samplingbar.h pv/view/cursor.h + pv/view/cursorheader.h pv/view/header.h pv/view/logicsignal.h pv/view/marginwidget.h diff --git a/pv/view/cursorheader.cpp b/pv/view/cursorheader.cpp new file mode 100644 index 00000000..d1660276 --- /dev/null +++ b/pv/view/cursorheader.cpp @@ -0,0 +1,127 @@ +/* + * This file is part of the PulseView project. + * + * Copyright (C) 2012 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.
