From 5f66639e069f276a20f27373a0c2e7dd9d94f390 Mon Sep 17 00:00:00 2001 From: Alan Alpert Date: Thu, 27 May 2010 15:35:17 +0200 Subject: Tweak aesthetics of QML viewer inside QtDemo Make the UX more controlled from QML, and tweak the frame to be better. Blur mechanism has been reworked, but still disabled by default. --- demos/qtdemo/MagicAnim.qml | 60 --------------- demos/qtdemo/colors.cpp | 2 +- demos/qtdemo/mainwindow.cpp | 12 +-- demos/qtdemo/menumanager.cpp | 35 ++++----- demos/qtdemo/menumanager.h | 3 +- demos/qtdemo/qmlShell.qml | 177 +++++++++++++++++++++++-------------------- demos/qtdemo/qtdemo.pro | 3 +- demos/qtdemo/qtdemo.qrc | 1 - 8 files changed, 118 insertions(+), 175 deletions(-) delete mode 100644 demos/qtdemo/MagicAnim.qml diff --git a/demos/qtdemo/MagicAnim.qml b/demos/qtdemo/MagicAnim.qml deleted file mode 100644 index 7ac3e1c..0000000 --- a/demos/qtdemo/MagicAnim.qml +++ /dev/null @@ -1,60 +0,0 @@ -/**************************************************************************** -** -** Copyright (C) 2010 Nokia Corporation and/or its subsidiary(-ies). -** All rights reserved. -** Contact: Nokia Corporation (qt-info@nokia.com) -** -** This file is part of the demonstration applications of the Qt Toolkit. -** -** $QT_BEGIN_LICENSE:LGPL$ -** No Commercial Usage -** This file contains pre-release code and may not be distributed. -** You may use this file in accordance with the terms and conditions -** contained in the Technology Preview License Agreement accompanying -** this package. -** -** GNU Lesser General Public License Usage -** Alternatively, this file may be used under the terms of the GNU Lesser -** General Public License version 2.1 as published by the Free Software -** Foundation and appearing in the file LICENSE.LGPL included in the -** packaging of this file.
