VR
- The visual root node of the UI toolkit this IVisualPart
is
used in, e.g. javafx.scene.Node in case of JavaFX.public class SetRefreshVisualOperation<VR> extends AbstractOperation implements ITransactionalOperation
SetRefreshVisualOperation
is used to set/unset the
IVisualPart.isRefreshVisual()
flag of a specified IVisualPart
. This can be handy to guard other operations from model refreshes.Constructor and Description |
---|
SetRefreshVisualOperation(IVisualPart<VR,? extends VR> part,
boolean from,
boolean to)
Creates a new
SetRefreshVisualOperation for setting the
IVisualPart.isRefreshVisual() flag of the given
IVisualPart to the to value on execution and to the
from value on undoing. |

Returns
true if this ITransactionalOperation is
actually changing model data (instead of only affecting the
visualization). |

isNoOp()
Returns
true if this ITransactionalOperation has no
effect (in comparison to its initial state). |
