[Solved] Building a feature-reduced Qt - suddenly GraphicsView is gone

[Asperamanca]

I am trying to build a feature-reduced Qt for an embedded device with GUI.

Now, I get tons of compile errors like this:
@error: invalid use of incomplete type 'struct QGraphicsWidget'@

It looks like Qt no longer knows GraphicsView classes.
Removing GraphicsView was not my intention, and I don't see anything in my configuration that indicates GraphicsView should not be included.

Any ideas what I am missing? I assume there is some implicit dependency I am missing.

Here is the ./configure call:

@./configure -qconfig tcl -embedded arm -xplatform qws/linux-arm-g++ -static -little-endian
-prefix /usr/local/qt-4.7.3-arm-static -qt-mouse-tslib
-qt-zlib -qt-libpng -qt-libjpeg -qt-libmng -silent
-no-largefile -no-qt3support -no-xmlpatterns -no-multimedia -no-audio-backend -no-phonon -no-phonon-backend
-no-svg -no-webkit -no-javascript-jit -no-script -no-scripttools -no-declarative -no-declarative-debug
-nomake demos -nomake examples -nomake tools -nomake translations -nomake docs@

The QGraphicsWidget is a combination of QGraphicsObject and QWidget, so you might have removed something from either branch to cause that particular error. Are the other errors all QGraphicsWidget related or are they QGraphics*?

If it's the former then I would guess that one of the later defines in your config file (rubberband etc.) has broken the widget class.

[Asperamanca]

QGraphicsWidget is not a combination of QGraphicsObject and QWidget, but a combination of QGraphicsObject and QGraphicsLayoutItem.

I wouldn't mind if QGraphicsProxyWidget didn't work, on the other hand, I can't display a graphics scene without a QGraphicsView, which is a QWidget. I need those anyway.

Sorry for the wrong information... teach me to fire off a post without checking the code! :)

[Asperamanca]

I guess I found it.

GraphicsView requires ScrollArea, ScrollArea requires ScrollBar, ScrollBar requires Slider.

Which I had unchecked.
