Member Function Documentation

◆ redo()

void KisActivateSelectionMaskCommand::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 KUndo2Command.

Definition at line 27 of file kis_activate_selection_mask_command.cpp.

{
    m_selectionMask->setActive(m_value);
}

References m_selectionMask, m_value, and KisSelectionMask::setActive().

◆ undo()

void KisActivateSelectionMaskCommand::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.

See also: redo()

Reimplemented from KUndo2Command.
