Warning: QMetaObject::connectSlotsByName: No matching signal for on_XXX_YYY()

[ruimaciel]

The following warnings are emitted when launching the app:

16:22:32: Starting /home/rui/develop/C++/TexasSolver/build/TexasSolverGui-Desktop_Qt_5_15_2_GCC_64bit/Debug/TexasSolverGui...
Warning: QMetaObject::connectSlotsByName: No matching signal for on_import_params() ((null):0, (null))
Warning: QMetaObject::connectSlotsByName: No matching signal for on_export_params() ((null):0, (null))
Warning: QMetaObject::connectSlotsByName: No matching signal for on_clear_all() ((null):0, (null))
Warning: QMetaObject::connectSlotsByName: No matching signal for on_ip_range(QString) ((null):0, (null))

These warnings are caused by the slots' naming convention conflicting with Qt's autoconnect feature. See this Qt forum post.

The goal of this issue is to prevent the app from emitting these warnings.
