// The only way to fix this in the current architecture

// in AudacityProject::UpdateMenus() (ugly)

// and CommandManager::HandleCommandEntry() (*really* ugly --

// shouldn't know about particular command names and flags).

|

// AudacityProject::UpdateMenus(), if somebody decides to do it:
|
||||
// // Because EnableUsingFlags requires all the flag bits match the
|
||||
// // corresponding mask bits,
|
||||
// // "UndoHistory" specifies only
|
||||
// // AudioIONotBusyFlag | UndoAvailableFlag, because that
|
||||
// // covers the majority of cases where it should be enabled.
|
||||
// // If history is not empty but we've Undone the whole stack,
|
||||
// // we also want to enable,
|
||||
// // to show the Redo's on stack.
|
||||
// // "UndoHistory" might already be enabled,
|

// // but add this check for RedoAvailableFlag.

// if (flags & RedoAvailableFlag)

// GetCommandManager()->Enable(wxT("UndoHistory"), true);

// So for now, enable the command regardless of stack.
|
||||
// It will just show empty sometimes.
|
||||
// FOR REDESIGN,
|
||||
// clearly there are some limitations with the flags/mask bitmaps.
