"""
bal.gui.qt.widgets
==================
Reusable, self-contained Qt widgets used to build the BAL tabs and dialogs.
These are "leaf" widgets: they receive the :class:`BalWindow` controller (and
any data they need) as constructor arguments at runtime, so this module does
not import ``window``/``dialogs`` and therefore introduces no import cycles.
Contents:
* ClickableLabel, BalLineEdit, BalTextEdit, BalCheckBox - thin Qt wrappers
* BalTxFeesWidget - fee-rate editor
* _LockTimeEditor + BalTimeEditWidget + raw/date editors - locktime editing
* ThresholdTimeWidget / LockTimeWidget - threshold & locktime
* WillSettingsWidget - the settings panel
* PercAmountEdit - amount-or-percentage editor
* WillWidget - single will-tx box
