From 38be0d13830efd2d98281c645c3a60afe05ffece Mon Sep 17 00:00:00 2001 From: Qt by Nokia Date: Wed, 27 Apr 2011 12:05:43 +0200 Subject: Initial import from the monolithic Qt. This is the beginning of revision history for this module. If you want to look at revision history older than this, please refer to the Qt Git wiki for how to use Git history grafting. At the time of writing, this wiki is located here: http://qt.gitorious.org/qt/pages/GitIntroductionWithQt If you have already performed the grafting and you don't see any history beyond this commit, try running "git log" with the "--follow" argument. Branched from the monolithic repo, Qt master branch, at commit 896db169ea224deb96c59ce8af800d019de63f12 --- examples/painting/fontsampler/fontsampler.pro | 12 + examples/painting/fontsampler/main.cpp | 51 ++++ examples/painting/fontsampler/mainwindow.cpp | 372 ++++++++++++++++++++++++ examples/painting/fontsampler/mainwindow.h | 82 ++++++ examples/painting/fontsampler/mainwindowbase.ui | 140 +++++++++ 5 files changed, 657 insertions(+) create mode 100644 examples/painting/fontsampler/fontsampler.pro create mode 100644 examples/painting/fontsampler/main.cpp create mode 100644 examples/painting/fontsampler/mainwindow.cpp create mode 100644 examples/painting/fontsampler/mainwindow.h create mode 100644 examples/painting/fontsampler/mainwindowbase.ui (limited to 'examples/painting/fontsampler') diff --git a/examples/painting/fontsampler/fontsampler.pro b/examples/painting/fontsampler/fontsampler.pro new file mode 100644 index 0000000000..9d845c413d --- /dev/null +++ b/examples/painting/fontsampler/fontsampler.pro @@ -0,0 +1,12 @@ +FORMS = mainwindowbase.ui +HEADERS = mainwindow.h +SOURCES = main.cpp \ + mainwindow.cpp + +# install +target.path = $$[QT_INSTALL_EXAMPLES]/qtbase/painting/fontsampler +sources.files = $$SOURCES $$HEADERS $$RESOURCES $$FORMS fontsampler.pro +sources.path = $$[QT_INSTALL_EXAMPLES]/qtbase/painting/fontsampler +INSTALLS += target sources + +symbian: include($$QT_SOURCE_TREE/examples/symbianpkgrules.pri) diff --git a/examples/painting/fontsampler/main.cpp b/examples/painting/fontsampler/main.cpp new file mode 100644 index 0000000000..01c8adae53 --- /dev/null +++ b/examples/painting/fontsampler/main.cpp @@ -0,0 +1,51 @@ +/**************************************************************************** +** +** Copyright (C) 2011 Nokia Corporation and/or its subsidiary(-ies). +** All rights reserved. +** Contact: Nokia Corporation (qt-info@nokia.com) +** +** This file is part of the examples of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:BSD$ +** You may use this file under the terms of the BSD license as follows: +** +** "Redistribution and use in source and binary forms, with or without +** modification, are permitted provided that the following conditions are +** met: +** * Redistributions of source code must retain the above copyright +** notice, this list of conditions and the following disclaimer. +** * Redistributions in binary form must reproduce the above copyright +** notice, this list of conditions and the following disclaimer in +** the documentation and/or other materials provided with the +** distribution. +** * Neither the name of Nokia Corporation and its Subsidiary(-ies) nor +** the names of its contributors may be used to endorse or promote +** products derived from this software without specific prior written +** permission. +** +** THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS +** "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT +** LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +** A PARTICULAR PURPOSE ARE DISCLAIMED.
