Class TransformVisualOperation
java.lang.Object
org.eclipse.core.commands.operations.AbstractOperation
org.eclipse.gef.mvc.fx.operations.TransformVisualOperation
- All Implemented Interfaces:
IUndoableOperation,ITransactionalOperation
The
TransformVisualOperation can be used to change an Affine,
for example, one that is contained within the transformations list of a
Node to transform that Node.-

TransformVisualOperation
Constructs a newTransformVisualOperationto change the given nodeTransform.- Parameters:
transformablePart- TheITransformableContentPartthat will be transformed by this operation.
-
TransformVisualOperation
public TransformVisualOperation(ITransformableContentPart<? extends Node> transformablePart, Affine newTransform) Constructs a newTransformVisualOperationto change the given nodeTransform. The given newTransform will be applied to the nodeTransform upon execution of this operation.- Parameters:
transformablePart- TheITransformableContentPartthat will be transformed by this operation.newTransform- TheAffinethat will be set as the visual transformation for the givenITransformableContentPartupon execution of this operation.

Method Details
-
applyTransform
Sets the visual transformation to the givenAffine.- Parameters:
transform- TheAffinethat is to be set as the total visual transformation for theITransformableContentPart.

execute
- Specified by:
executein interfaceIUndoableOperation- Specified by:
executein classAbstractOperation- Throws:
ExecutionException
-
getInitialTransform
Returns the initialAffineof theITransformableContentPart.- Returns:
- The initial
Affineof theITransformableContentPart.
-
getNewTransform
Returns theAffinethat will be set as the transformation matrix of theITransformableContentPart.- Returns:
- The
Affinethat will be set as the transformation matrix of theITransformableContentPart.
-
isContentRelevant
public boolean isContentRelevant()Description copied from interface:ITransactionalOperationReturnstrueif thisITransactionalOperationis actually changing model data (instead of only affecting the visualization). Otherwise returnsfalse. The content relevance of anITransactionalOperationcan be checked to determine if the execution of the operation will affect the model, for example, to set an editor's dirty flag.- Specified by:
isContentRelevantin interfaceITransactionalOperation- Returns:
trueif thisITransactionalOperationis actually changing model data, otherwisefalse.
-
isNoOp
public boolean isNoOp()Description copied from interface:ITransactionalOperationReturnstrueif thisITransactionalOperationhas no effect (in comparison to its initial state). Otherwise returnsfalse.- Specified by:
isNoOpin interfaceITransactionalOperation- Returns:
trueif thisITransactionalOperationhas no effect, otherwisefalse.
-
redo
- Specified by:
redoin interfaceIUndoableOperation- Specified by:
redoin classAbstractOperation- Throws:
ExecutionException
-
setFinalTransform
Sets theAffinethat will be set as the transformation matrix of theITransformableContentPart.- Parameters:
newTransform- TheAffinethat will be set as the transformation matrix of theITransformableContentPart.
