From 0b7f30930be1318030b9749f352a8dec3b9c6f39 Mon Sep 17 00:00:00 2001 From: Ken Moore Date: Tue, 20 Jan 2015 16:22:03 -0500 Subject: Completely revamp the notepad desktop plugin so that it is now file-based instead of saving everything into the plugin settings directly. This allows it to manage generic text files as well as just the *.note files in ~/Notes. --- .../desktop-plugins/notepad/NotepadPlugin.cpp | 268 +++++++++++++++++---- 1 file changed, 221 insertions(+), 47 deletions(-) (limited to 'lumina-desktop/desktop-plugins/notepad/NotepadPlugin.cpp') diff --git a/lumina-desktop/desktop-plugins/notepad/NotepadPlugin.cpp b/lumina-desktop/desktop-plugins/notepad/NotepadPlugin.cpp index 214de63c..17372202 100644 --- a/lumina-desktop/desktop-plugins/notepad/NotepadPlugin.cpp +++ b/lumina-desktop/desktop-plugins/notepad/NotepadPlugin.cpp @@ -2,7 +2,10 @@ #include #include "LSession.h" - +#include +#include +#include +#include NotePadPlugin::NotePadPlugin(QWidget* parent, QString ID) : LDPlugin(parent, ID){ QVBoxLayout *vlay = new QVBoxLayout();
