/* Code_AutoShift is an abstract base class for Codes that depend on automatic shifting.
|
|
Code_AutoShift can manage one or more shift keys.
|
|
|
|
Example initialization:
|
|
const Code_Shift s_shift(MODIFIERKEY_LEFT_SHIFT);
|
|
const Code_Shift *const ptrsS[] = { &s_shift };
|
|
const Code_Shift *const *const Code_AutoShift::ptrsShifts = ptrsS;
|
|
const uint8_t Code_AutoShift::shiftCount = sizeof(ptrsShifts)/sizeof(*ptrsShifts);
|
|
The two Code_Shift pointer arrays (ptrsShifts and ptrsS) must have distinct names.
|
|
|
|
Automatic shifting is usful on multi-layered keyboards.
|
|
The shift state for Code_ScS and Code_ScNS are changed and restored:
|
|
Code_ScS object is a scancode shifted e.g. '%' in symbols layer
|
|
Code_ScNS object is a scancode not shifted e.g. '5' in numbers layer
|
|
|
|
keyboards without Code_ScS and Code_ScNS can omit ptrsShifts[] array and
|
|
and place scancode MODIFIERKEY_LEFT_SHIFT directly in Code_Sc:
|
|
Code_Sc s_shift(MODIFIERKEY_LEFT_SHIFT);
