Well, this morning I implemented the first bit of support for QTabletEvent,=
=20
and took me along a tour of the Krita innards, so I'm a bit more confident=
=20
now.=20

I still need to expand Krita to know  that it can have three different acti=
ve=20
tools now, of course, instead of just one: mouse, stylus and eraser, but=20
that's not that urgent, and it's just administrative code coupled with a bi=
t=20
of ui.

I've also started on a KisToolPaint base class analogous to KisToolNonPaint=
,=20
with a silly test class as a first client. And here I run into a bit of KDE=
=20
arcana that I don't know how to handle; perhaps I should CC to kde-devel, i=
f=20
you cannot say out of hand what I'm doing wrong.

The goal is to have a mouse-press event paint something to the image, so I=
=20
implemented the following, analogous to similar code in=20
KisToolRectangularSelect:

void KisToolTest::mousePress(QMouseEvent *e)
{
    KisImageSP img =3D m_view -> currentImg();
    if (img) {
        KisPaintDeviceSP parent =3D=3D img -> activeDevice();
        if (parent) {
             // use parent to paint something, no matter what
             m_doc -> addCommand(new TestCmd(img));
         }
    }
}

Compiling this results in the following error:

Have you got any idea, or had I better ask on kde-devel?
