Hi Dirk, See the attached updated patch, I hope it is OK. I am still working on the OS detection feature. -- *With Kind Regards,* *Joseph W Joshua* *+254 724 276 654*
From 1b8f2a187ecba70f9c11d9bf071188eb56557c4d Mon Sep 17 00:00:00 2001 From: Joshua Wambua <jos...@megvel.me.ke> Date: Wed, 2 Apr 2014 09:49:03 +0300 Subject: [PATCH] Add "Check for updates" Feature This patch adds a check for updates feature. On windows and mac, it connects to http://subsurface.hohndel.org/updatecheck.html to check for any new versions. It then prompts the user with a download link if an update is available Signed-off-by: Joshua Wambua <joejo...@gmail.com> --- qt-ui/mainwindow.cpp | 11 +++++++++ qt-ui/mainwindow.h | 1 + qt-ui/mainwindow.ui | 6 +++++ qt-ui/updatemanager.cpp | 63 +++++++++++++++++++++++++++++++++++++++++++++++++ qt-ui/updatemanager.h | 21 +++++++++++++++++ subsurface.pro | 6 +++-- 6 files changed, 106 insertions(+), 2 deletions(-) create mode 100644 qt-ui/updatemanager.cpp create mode 100644 qt-ui/updatemanager.h diff --git a/qt-ui/mainwindow.cpp b/qt-ui/mainwindow.cpp index b632252..b2f9947 100644 --- a/qt-ui/mainwindow.cpp +++ b/qt-ui/mainwindow.cpp @@ -37,6 +37,7 @@ #include "diveplanner.h" #include "about.h" #include "worldmap-save.h" +#include "updatemanager.h" #ifndef NO_PRINTING #include "printdialog.h" #endif @@ -97,6 +98,10 @@ MainWindow::MainWindow() : QMainWindow(), #ifdef NO_PRINTING ui.menuFile->removeAction(ui.actionPrint);
