libQGLViewer installation
on windowsWindows

This source code is released under the GPL license. If you are using libQGLViewer in a commercial application, you need to purchase a libQGLViewer commercial license.

Compilation from the sources

Make sure your Qt installation is up to date and running. Try building one of the Qt OpenGL examples first.

Then download and unzip

Depending on your environment:

Then copy the generated QGLViewer2.dll and QGLViewer2d.dll to a system shared directory such as C:\Windows\System32. An alternative is to copy the dll in every executable's directory.

See the compilation with libQGLViewer page for details on examples' compilation.

* You can generate the .vcproj file by typing qmake -t vclib -spec win32-msvc2010 (adapt to your configuration) in a Qt command prompt window.

A LNK4068 /MACHINE warning message can be fixed by editing Project - Properties of QGLViewer - Configuration properties - Link editor - Advanced - Target Computer.

Visual Studio 6 only: Use File-Open workspace to open the .dsp generated file, and select Release as the Build/Active Configuration.

Qt Installation of the designer plugin

The compilation and installation of the QGLViewer designer plugin is optional. It eases the creation of user interfaces that feature a QGLViewer widget using Qt designer. Simply drag and drop the QGLViewer icon that appears in the designer's Display Widgets tab to add it to your interface:

        designer plugin

When added to your user interface, the widget displays the standard spiral, which can be manipulated when you test your interface. All the viewers' signals and slots are available and can be connected to the rest of your interface.

To compile the plugin, open the file to create your workspace. Install the resulting plugin library (qglviewerplugin.dll) in $QTDIR\plugins\designer and/or C:\Program Files\QtSoftware\Qt VS Integration\plugins to use it with the Visual Studio integrated designer.

Make sure you are building and using the Release version of QGLViewer2.dll. Note that you also have to install QGLViewer2.dll in C:\Windows\System32 (as described above). Copying this file to $QTDir\bin sometimes also seems necessary.

To create your own designer plugin for your derived QGLViewer class, start from this code and change a few lines as explained in the source.

See the interface example for an illustration of a user interface that includes a QGLViewer.

Please let me know if you encounter installation problems.
