Replace expensive inherits with cheaper qobject_cast (2)

Browse Source 
In the Windows 11 style, it's better to include the headers for specific
widget types at the expense of compile time, than to pay a regular
runtime cost from using expensive inherits().

Add const, fix style, and break excessively long lines related to this
change.
