Member Function Documentation

canAnnihilateWith()

bool KisNodePropertyListCommand::canAnnihilateWith ( const KUndo2Command * other ) const

overridevirtual

Attempts to merge this command with command and checks if the two commands compensate each other. If the function returns true, both commands are removed from the stack.

If this function returns true, calling this command's redo() followed by other redo() must have no effect.

The function itself shouldn't do any changes to the command, because after returning true, the command will be deleted as a "noop"

KUndo2QStack will only try to merge two commands if they have the same id, and the id is not -1.

The default implementation returns false.

id() KUndo2QStack::push()

Reimplemented from KUndo2Command.

            changedProperties(m_oldPropertyList, other->m_newPropertyList).isEmpty();
}

References m_newPropertyList, KisNodeCommand::m_node, and m_oldPropertyList.

canMergeWith()

bool KisNodePropertyListCommand::canMergeWith ( const KUndo2Command * command ) const

overridevirtual

Returns

true if command can be merged with (*this) command using KUndo2Command::mergeWith() call.

WARNING: if canMergeWith() returned true, then mergeWith() must also return true. Otherwise KisSavedMacroCommand will be able to enter inconsistent state and assert.

Implements KisAsynchronouslyMergeableCommandInterface.

doUpdate()

void KisNodePropertyListCommand::doUpdate ( const KisBaseNode::PropertyList & oldPropertyList, const KisBaseNode::PropertyList & newPropertyList, const QRect & totalUpdateExtent )

private

Sometimes the node might refuse to change the property, e.g. needs-update for colorize mask. In this case we should avoid issuing the update and set-modified call.

id()

int KisNodePropertyListCommand::id ( ) const

overridevirtual

Returns the ID of this command.

A command ID is used in command compression. It must be an integer unique to this command's class, or -1 if the command doesn't support compression.

If the command supports compression this function must be overridden in the derived class to return the correct ID. The base implementation returns -1.

KUndo2QStack::push() will only try to merge two commands if they have the same ID, and the ID is not -1.

References KisCommandUtils::NodePropertyListCommandId.

mergeWith()

bool KisNodePropertyListCommand::mergeWith ( const KUndo2Command * command )

overridevirtual

Attempts to merge this command with command. Returns true on success; otherwise returns false.

If this function returns true, calling this command's redo() must have the same effect as redoing both this command and command. Similarly, calling this command's undo() must have the same effect as undoing command and this command.

KUndo2QStack will only try to merge two commands if they have the same id, and the id is not -1.

The default implementation returns false.

redo()

void KisNodePropertyListCommand::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.

setNodePropertiesAutoUndo()

void KisNodePropertyListCommand::setNodePropertiesAutoUndo ( KisNodeSP node, KisImageSP image, PropertyList proplist )

static

HACK ALERT!

Here we start a fake legacy stroke, so that all the LoD planes would be invalidated. Ideally, we should refactor this method and avoid resetting LoD planes when node visibility changes, Instead there should be two commands executes: LoD agnostic one (which sets the properties themselves), and two LoD-specific update commands: one for lodN and another one for lod0.

undo()

void KisNodePropertyListCommand::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.
