Member Function Documentation

◆ createCoalescedAction()

UndoableAction * juce::ValueTree::SharedObject::MoveChildAction::createCoalescedAction ( UndoableAction * nextAction )

overridevirtual

Allows multiple actions to be coalesced into a single action object, to reduce storage space.

If possible, this method should create and return a single action that does the same job as this one followed by the supplied action.

If it's not possible to merge the two actions, the method should return a nullptr.

Reimplemented from juce::UndoableAction.

◆ getSizeInUnits()

int juce::ValueTree::SharedObject::MoveChildAction::getSizeInUnits ( )

overridevirtual

Returns a value to indicate how much memory this object takes up.

Because the UndoManager keeps a list of UndoableActions, this is used to work out how much space each one will take up, so that the UndoManager can work out how many to keep.

The default value returned here is 10 - units are arbitrary and don't have to be accurate.
