From e49d6213ad129284a45d53c3fcdc03249e84efe2 Mon Sep 17 00:00:00 2001 From: Tomaz Canabrava Date: Thu, 3 Sep 2015 14:20:19 -0300 Subject: Move qt-ui to desktop-widgets Since we have now destkop and mobile versions, 'qt-ui' was a very poor name choice for a folder that contains only destkop-enabled widgets. Also, move the graphicsview-common.h/cpp to subsurface-core because it doesn't depend on qgraphicsview, it merely implements all the colors that we use throughout Subsurface, and we will use colors on both desktop and mobile versions Same thing applies for metrics.h/cpp Signed-off-by: Tomaz Canabrava Signed-off-by: Dirk Hohndel --- desktop-widgets/usermanual.cpp | 151 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 151 insertions(+) create mode 100644 desktop-widgets/usermanual.cpp (limited to 'desktop-widgets/usermanual.cpp') diff --git a/desktop-widgets/usermanual.cpp b/desktop-widgets/usermanual.cpp new file mode 100644 index 000000000..6b676f16b --- /dev/null +++ b/desktop-widgets/usermanual.cpp @@ -0,0 +1,151 @@ +#include +#include +#include + +#include "usermanual.h" +#include "mainwindow.h" +#include "helpers.h" + +SearchBar::SearchBar(QWidget *parent): QWidget(parent) +{ + ui.setupUi(this);
