I tried that but  can't get it to work: it compiles, but the actions
don't show up in the right click menu.

Here's what I did. In my Mandelbrot (inheriting Wallpaper) class I
have new members,

        QAction m_exportImageAction;
        QAction m_exportConfigAction;
        QAction m_importConfigAction;

Then they are initialized in the initialization list of my Mandelbrot
constructor:

Mandelbrot::Mandelbrot(QObject *parent, const QVariantList &args)
    : Plasma::Wallpaper(parent, args), m_image(0), m_tiling(this),
      m_exportImageAction(i18n("Export image..."), 0),
      m_exportConfigAction(i18n("Export parameters..."), 0),
      m_importConfigAction(i18n("Import parameters..."), 0),

Then, in the body of that constructor, I do:

    contextualActions().append(&m_exportImageAction);
    contextualActions().append(&m_exportConfigAction);
    contextualActions().append(&m_importConfigAction);

    connect(&m_exportImageAction, SIGNAL(triggered()), this,
SLOT(exportImage()));
    connect(&m_exportConfigAction, SIGNAL(triggered()), this,
SLOT(exportConfig()));
    connect(&m_importConfigAction, SIGNAL(triggered()), this,
SLOT(importConfig()));

What am I doing wrong?

Thanks
Benoit
