[edit] Introduction

This article shows how to find out the current version of Qt, Qt Mobility and also OpenGL.


[edit] Prerequisities

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

[edit] 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();
}

The QGLFormat class specifies the display format of an OpenGL rendering context.

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