Registered by UI.CreateEdit

UIFS_MoveZoomTo (DryOS)Edit

• arguments

1. zoom point (0, 1,  ... ) starts with optical, adds digital zoom when the optical maximum is reached
2. ignored
3. function pointer, probably callback, disabled when 0

• notes

on A470, digital zoom set with this eventproc may not be persistent

--[[
@title MoveZoomTo
@param a Param
@default a 0
]]
call_event_proc("UI.Create")
call_event_proc("UIFS_MoveZoomTo",a,0,0)

UIFS_CaptureNoneStopEdit

• arguments

1. unknown

• notes

on the A470, calling this with a nonzero argument resulted in an unstoppable endless shooting loop

UIFS_SetCaptureModeToTv, 
UIFS_SetCaptureModeToMEdit

• arguments

has no arguments

• notes

changes active capture mode with correct shooting menu, on the A470 both set something similar to the "long shutter" submode of P mode (their effect is slighly different)
Might cause instability (confused camera?)

UIFS_WriteFirmInfoToFileEdit

• arguments

1. filename (?), 0 for the default "A/Firminfo.txt"

• notes

writes firmware information followed by a list of recent recorded errors into the file

call_event_proc("UI.Create")
call_event_proc("UIFS_WriteFirmInfoToFile",0)

PT_* event proceduresEdit

The first 11 event procedures of the PT_* eventproctable are called by firmware tasks by name, so they can be overridden

These are:

PT_CompletePreCaptEdit

PT_RecreviewAvailableEdit

PT_NextShootAvailableEdit

PT_CompleteStopZoomEdit

PT_CompleteStopDigZoomEdit

PT_CompleteStoreLensEdit

PT_MovieRecordStoppedEdit

PT_CompleteCaptModeChangeEdit

PT_CompleteSynchroWriteEdit

• does not seem to be called on the A470, so it's useless
  

PT_CompleteChargeEdit

PT_CompleteFileWriteEdit
