This removes the option from the wallet to not pay a fee on "small"
transactions which spend "old" inputs.
This code is no longer worth keeping around, as almost all miners
prefer not to include transactions which pay no fee at all.
None of these are very serious, and are leaks in objects that are
created at most one time.
In most cases this means properly using the QObject parent hierarchy,
except for BanTablePriv/PeerTablePriv which are not QObject,
so use a std::unique_ptr instead.
- Do sorting for date, amount and confirmations column as longlong, not
unsigned longlong.
- Use `UserRole` to store our own data. This makes it treated as
ancillary data prevents it from being displayed.
- Get rid of `getMappedColumn` `strPad` - these are no longer necessary.
- Get rid of hidden `_INT64` columns.
- Start enumeration from 0 (otherwise values are undefined).
* Introduce new constant MIN_CHANGE and use it instead of the
hardcoded "CENT"
* Add test case for MIN_CHANGE
* Introduce new constant for -mintxfee default:
DEFAULT_TRANSACTION_MINFEE = 1000
Introduce a PlatformStyle to handle platform-specific customization of
the UI.
This replaces 'scicon', as well as #ifdefs to determine whether to place
icons on buttons.
The selected PlatformStyle defaults to the platform that the application
was compiled on, but can be overridden from the command line with
`-uiplatform=<x>`.
Also fixes the warning from #6328.
QT_NO_KEYWORDS prevents Qt from defining the `foreach`, `signals`,
`slots` and `emit` macros.
Avoid overlap between Qt macros and boost - for example #undef hackiness
in #6421.
If uint256() constructor takes a string, uint256(0) will become
dangerous when uint256 does not take integers anymore (it will go
through std::string(const char*) making a NULL string, and the explicit
keyword is no help).
