Member Function Documentation

◆ Restore()

void Restore ( int  isUndo)
virtual
Remarks
The developer implements this method to restore the state of the database to as it was when theHold.Put() was called with this restore object.

Regardless of the value of the isUndo parameter, the method must restore the state of the scene to the one it was in when theHold.Put() was called with this restore object.

RestoreObj::Restore and RestoreObj::Redo may be called several times in a row: these methods must protect against any problems that may arise because of this, such as trying to undo multiple times in a row what has been undone already.
Parameters
isUndoNonzero if Restore() is being called in response to the Undo command; otherwise zero. If isUndo is nonzero, the developer needs to save whatever data they need to allow the user to redo the operation.

Implements RestoreObj.

◆ Redo()

void Redo ( )
virtual
Remarks
This method is called when the user selects the Redo command. The developer should restore the database to the state prior to the last Undo command.

Implements RestoreObj.

◆ Size()

int Size ( )
inlinevirtual
Remarks
Returns the size of the restore object in bytes. This size does not need to be exact but should be close. This is used to make sure all the accumulated restore objects do not grow beyond a manageable size.
Default Implementation:
{ return 1; }
Returns
The size of the restore object in bytes.

Reimplemented from RestoreObj.

1440 { return 1; }

◆ EndHold()

void EndHold ( )
inlinevirtual
Remarks
This method is called when theHold.Accept() or theHold.Cancel() is called. This means the restore object is no longer held, it was either tossed out or sent to the undo system. The developer may then call ClearAFlag(A_HELD) to indicate the restore object is no longer being held.

Reimplemented from RestoreObj.

1441 {po->ClearAFlag(A_HELD);}
void ClearAFlag(DWORD mask)
Clears one or more bits in the Animatable flags.
Definition: Animatable.h:304
PatchObject * po
Definition: patchobj.h:1433
#define A_HELD
Typically a plug-in would not hold unless this flag was not set.
Definition: AnimatableFlags.h:159

◆ Description()

MSTR Description ( )
inlinevirtual
Remarks
This method is used internally to 3ds Max in debugging only. It is used to display a symbolic name for the restore object.
Returns
The name of the restore object.
Default Implementation:
{ return MSTR(_M("---")); }

Reimplemented from RestoreObj.

1442 { return MSTR(_M("PatchObject restore")); }
#define _M(x)
Used to wrap string literals.
Definition: strbasic.h:67
WStr MSTR
Definition: strclass.h:1058
