When a source file contains an explicit include with a filename
following the "moc_<actual-filename>.cpp" pattern, then CMake's
AUTOMOC generation tool will recognize the matching pair and generate
the replacement header file and add the required include directory
entries.
For all files which do contain Q_OBJECT or similar declarations but do
not have an explicit include directive, the global mocs_compilation.cpp
file will still be generated (which groups all "missing" generated
headers).
The larger this global file is, the more expensive incremental
compilation will be as this file (and all its contained generated
headers) will be re-generated regardless of whether actual changes
occurred.
LineEditAutoResize didn't have its maxLength initialized in the
constructor, leaving it to be a random value until set via setMaxLength.
The one place where LineEditAutoResize was used immediately set this
after calling the constructor, but if we use this anywhere else in the
future it makes sense to have this initialized.
As it is meant to mostly behave like a QLineEdit, lets use the same
default value of 32767.
