Member Function Documentation

◆ redo()

void KisReselectActiveSelectionCommand::redo ( )

overridevirtual

Applies a change to the document. This function must be implemented in the derived class. Calling KUndo2QStack::push(), KUndo2QStack::undo() or KUndo2QStack::redo() from this function leads to undefined behavior.

The default implementation calls redo() on all child commands.

See also: undo()

Reimplemented from KisCommandUtils::AggregateCommand.

◆ undo()

void KisReselectActiveSelectionCommand::undo ( )

overridevirtual

Reverts a change to the document. After undo() is called, the state of the document should be the same as before redo() was called. This function must be implemented in the derived class. Calling KUndo2QStack::push(), KUndo2QStack::undo() or KUndo2QStack::redo() from this function leads to undefined behavior.

The default implementation calls undo() on all child commands in reverse order.
