templateview.h only included <QGraphicsView> but uses
QGraphicsGridLayout (tbgrid_ member) and QGraphicsLayoutItem
(indexOf/removeItem signatures) directly. Some Qt5 header
apparently pulled these in transitively; Qt6's leaner headers
don't, so the class fields/methods silently failed to resolve
and the compiler picked bogus 'int*' overloads instead.
Other files in the same directory already get these symbols
either via the <QtWidgets> umbrella header or a direct include,
so this was an isolated gap.
MOC on macOS does not resolve QGraphicsLayoutItem through the bulk
QtWidgets include, causing an 'Undefined interface' error at build time.
Adding an explicit include resolves this. Linux builds are unaffected. Thanks hairykiwi 8ef4e04
clazy is a compiler plugin which allows clang to understand Qt
semantics. You get more than 50 Qt related compiler warnings, ranging
from unneeded memory allocations to misusage of API, including fix-its
for automatic refactoring.

All export files that are derived from the project (BOM,
nomenclature, etc.) are saved in the same directory by default.
In this context, the standard directories have been grouped
together in qetapp.cpp / qetapp.h so that only one place needs
to be searched for in case of any adjustments.
(Deprecated) The dock widget can be closed, moved, and floated.
Since new features might be added in future releases,
the look and behavior of dock widgets might change if you use this flag.
Please specify individual flags instead.
Use angleDelta() instead
manhattanLength()
Returns the sum of the absolute values of x() and y(),
traditionally known as the "Manhattan length" of the vector
from the origin to the point.
This class was introduced in Qt 5.5
We need to define our own copy constructor only
if an object has pointers or any runtime allocation
of the resource like file handle, a network connection..etc.
note: Default constructor does only shallow copy.
This function is obsolete.
Note:
This function was provided as a workaround for MSVC 6
which did not support member template functions.
It is advised to use the other form in new code.
This function is equivalent to QVariant::fromValue(value).
