Introduction

This small utility application can be used to find out the current versions of Qt and Qt Mobility and also OpenGL.

Prerequisities

You would need the Qt SDK installed to compile the utility example code.

Example code

#include <QtGui>
#include <QtOpenGL>
#include <qmobilityglobal.h>
 
const char* openglVersion()
{
const char *OpenGLVersion;
switch (QGLFormat::openGLVersionFlags()) {
case QGLFormat::OpenGL_Version_1_1:
OpenGLVersion = "OpenGL 1.1";
break;
case QGLFormat::OpenGL_Version_1_2:
OpenGLVersion = "OpenGL 1.2";
break;
case QGLFormat::OpenGL_Version_1_3:
OpenGLVersion = "OpenGL 1.3";
break;
case QGLFormat::OpenGL_Version_1_4:
OpenGLVersion = "OpenGL 1.4";
break;
case QGLFormat::OpenGL_Version_1_5:
OpenGLVersion = "OpenGL 1.5";
break;
case QGLFormat::OpenGL_Version_2_0:
OpenGLVersion = "OpenGL 2.0";
break;
case QGLFormat::OpenGL_Version_2_1:
OpenGLVersion = "OpenGL 2.1";
break;
case QGLFormat::OpenGL_Version_3_0:
OpenGLVersion = "OpenGL 3.0";
break;
case QGLFormat::OpenGL_ES_CommonLite_Version_1_0:
OpenGLVersion = "OpenGL ES Common Lite 1.0";
break;
case QGLFormat::OpenGL_ES_Common_Version_1_0:
OpenGLVersion = "OpenGL ES Common Lite 1.0";
break;
case QGLFormat::OpenGL_ES_CommonLite_Version_1_1:
OpenGLVersion = "OpenGL ES Common Lite 1.1";
break;
case QGLFormat::OpenGL_ES_Common_Version_1_1:
OpenGLVersion = "OpenGL ES Common Lite 1.1";
break;
case QGLFormat::OpenGL_ES_Version_2_0:
OpenGLVersion = "OpenGL ES 2.0";
break;
case QGLFormat::OpenGL_Version_None:
default:
OpenGLVersion = "No Open GL";
break;
}
return OpenGLVersion;
}
 
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
 
QFont font("Nokia Sans", 32);
QLabel label;
label.setFont(font);
label.setText(QString("%1Qt: %2<br>Runtime Qt: %3<br>Qt Mobility: %4<br>OpenGL: %5")
.arg(qstrcmp(QT_VERSION_STR, qVersion()) ? "<h1 style=\"color: red\">Mismatch detected!</h1>" : "")
.arg(QT_VERSION_STR)
.arg(qVersion())
.arg(QTM_VERSION_STR)
.arg(openglVersion()));
label.setAlignment(Qt::AlignCenter);
label.show();
 
return a.exec();
}


You should compile this example for yourself using the SDK for your target device.
