Member Function Documentation

redo()

void KisSuspendProjectionUpdatesStrokeStrategy::Private::EndBatchUIUpdatesCommand::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.

undo()

void KisSuspendProjectionUpdatesStrokeStrategy::Private::EndBatchUIUpdatesCommand::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.

redo()

Even though this command is the last command of the stroke is can still be undone by suspendStrokeCallback(). It happens when a LodN stroke is started right after the last job of resume strategy was being executed. In such a case new stroke is placed right in front of our resume strategy and all the resuming work is undone (mimicking a normal suspend strategy).

The only thing we should control here is whether the state of the stroke is reset to default. Otherwise we'll do all the updates twice.

Reimplemented from KUndo2Command.
