Member Function Documentation

◆ redo()

template<typename Base , typename Member , Member Base::* mem_ptr, typename ValueType >

void KisChangeValueCommand< mem_ptr, ValueType >::redo ( )

inlinevirtual

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 KUndo2Command.

Definition at line 38 of file KisChangeValueCommand.h.

                {
        KUndo2Command::redo();
        m_base->*mem_ptr = m_newValue;
    }

References KUndo2Command::redo().

◆ undo()

template<typename Base , typename Member , Member Base::* mem_ptr, typename ValueType >

void KisChangeValueCommand< mem_ptr, ValueType >::undo ( )

inlinevirtual

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.

See also: redo()

Reimplemented from KUndo2Command.

                {
        m_base->*mem_ptr = m_oldValue;
        KUndo2Command::undo();
