* emu/ioport.h: Made syntax for configuring callbacks more consistent. Vas Crabb2024-10-181-1/+1
| | | | | | | | | | | | You now use FUNC or NAME to configure port field callbacks, like you would when configuring other kinds of callbacks. This has a number of benefits: * No need to remember different syntax for port field callbacks, and more approachable for new contributors. * May use function templates with multiple arugments using NAME((&...)) syntax without resorting to another layer of macros. * May use non-member functions on the odd chance it's useful. * More natural syntax for referring to member functions.

* Cleaned up bitmap API. Vas Crabb2020-09-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Made const-qualified pixel accessors (pix, pixt, raw_pixptr) return const-qualified references/pointers to pixesl, and added non-const versions. This makes bitmap more like standard library containers where const protects the content as well as the dimensions. Made the templated pixt accessor protected - having it public makes it too easy to inadvertently get a pointer to the wrong location. Removed the pix(8|16|32|64) accessors from the specific bitmaps. You could only use the "correct" one anyway, and having the "incorrect" ones available prevented explicit instantiations of the class template because the static assertions would fail. You can still see the pixel type in the bitmap class names, and you can't assign the result of &pix(y, x) to the wrong kind of pointer without a cast. Added fill member functions to the specific bitmap template, and added a explicit instantiations. This allows the bitmap size check to be skipped on most bitmap fills, although the clipping check is still there. Also fixed a couple of places that were trying to fill an indexed 16-bit bitmap with rgb_t::black() exposed by this (replaced with zero to get the same net effect). The explicit template instantiations in the .cpp file mean the compiler can inline the function if necessary, but don't need to generate a local out-of-line body if it chooses not to. Extended the size of the fill value parameter in the base bitmap class to 64 bits so it works correctly for 64-bit bitmaps. Fixed places where IE15 and VGM visualiser weren't accounting for row bytes potentially being larger than width. Fixed an off-by-one in an HP-DIO card where it was treating the Topcat cursor right edge as exclusive. Updated everything to work with the API changes, reduced the scope of many variables, added more const, and replaced a few fill/copy loops with stuff from <algorithm>.
