Using resources in Qt

QRE.pro

Add a resource file to a project file:

#  Copyright (c) 2009 Nokia Corporation
TEMPLATE = app
TARGET = QRE
QT += core \
gui
SOURCES += main.cpp
# This is how the qre.qrc is added to the project.
RESOURCES += qre.qrc

qre.qrc

Add resources to a resource file:

<!-- Copyright (c) 2009 Nokia Corporation  -->
<RCC>
<qresource prefix="/" >
<file>qt-logo.png</file>
</qresource>
</RCC>

qt-logo.png

Qt-logo.png

main.cpp

Reference resources from the code:

/*
* Copyright (c) 2009 Nokia Corporation
*/

#include <QtGui>
#include <QApplication>
 
int main(int argc, char *argv[]) {
QApplication a(argc, argv);
/* QMainWindow as our window */
QMainWindow* w = new QMainWindow;
/* QFrame as our centralWidget */
QFrame* centralW = new QFrame(w);
w->setCentralWidget(centralW);
/* QVBoxLayout as our central widgets layout */
QVBoxLayout* layout = new QVBoxLayout(centralW);
centralW->setLayout(layout);
 
/* QLabel is used as our logo container. */
QLabel* qtLogoContainer = new QLabel;
/* QPixmap is used to load the image from resources
* defined in qre.qrc file. */

qtLogoContainer->setPixmap(QPixmap(":/qt-logo.png"));
/* To get the logo shown we need to add the container containing
* the logo to the layout. */

layout->addWidget(qtLogoContainer);
 
/* We'll display the window maximized. */
w->showMaximized();
/* Run till the execution ends. */
int returnValue = a.exec();
/* Flag the window to be deleted.*/
w->deleteLater();
/* Return the execution return value.*/
return returnValue;
}
