building a transfer function editor using QColorDialog
Message 1 in thread
Dear Qt-users,
I'm relatively new to Qt and I have a question concerning the QColorDialog.
I would like to use it in my application for interactively changing a
transfer
function used in volume rendering. Therefore, I would like to change the
dialog in a way that it returns its current color whenever the user moves
the cross within the colored square. Actually, I need the dialog to be a
widget
rather than a dialog because I want it to be visible all the time and
not for
a single user interaction. Has anybody an idea ?
Thanks in advance,
Steffen Oeltze

Hi Steffen,
just try to copy the QColorPicker class from
QColorDialog.cpp in the /src directory to your code.
This class is a QFrame subclass and, as a result, you
can deal with it as a widget.
