Member Function Documentation

redo()

void KisSelection::ChangeShapeSelectionCommand::redo ( )

inlineoverridevirtual

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 207 of file kis_selection.cc.

        KIS_SAFE_ASSERT_RECOVER_RETURN(m_selection);
 
        if (m_firstRedo) {

    }

References KIS_SAFE_ASSERT_RECOVER_RETURN, KisSelection::m_d, m_firstRedo, m_isFlatten, m_reincarnationCommand, m_selection, m_shapeSelection, and KisSelection::requestCompressedProjectionUpdate().

undo()

void KisSelection::ChangeShapeSelectionCommand::undo ( )

inlineoverridevirtual

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.
