EdgeObjectUVEditPolicy
public EdgeObjectUVEditPolicy()
createSelectionHandle
protected org.eclipse.gef.Handle createSelectionHandle(EdgeObject edgeObject)
- Create a selection handle for the given edge object.
- Overrides:
createSelectionHandle
in class EdgeObjectEditPolicy
- Parameters:
edgeObject
- the edge object for the one the selection handle has to
be created
- Returns:
- an handle or
null
if the given edge object must
not have selection handle
showSourceFeedback
public void showSourceFeedback(org.eclipse.gef.Request request)
- Specified by:
showSourceFeedback
in interface org.eclipse.gef.EditPolicy
- Overrides:
showSourceFeedback
in class org.eclipse.gef.editpolicies.AbstractEditPolicy
- See Also:
AbstractEditPolicy.showSourceFeedback(org.eclipse.gef.Request)
showSourceFeedBack
protected void showSourceFeedBack(int newUDistance,
int newVDistance,
EdgeObjectUV edgeObject)
- Shows or updates source feedback for the specified new uDistance,
vDistance and edge object.
Subclass must reimplement this method to
customize the feedback.
Default implementation makes the edge
object figure follow the mouse.
- Parameters:
uDistance
- a new uDistancevDistance
- a new vDistanceedgeObject
- an edge object
eraseSourceFeedback
public void eraseSourceFeedback(org.eclipse.gef.Request request)
- Specified by:
eraseSourceFeedback
in interface org.eclipse.gef.EditPolicy
- Overrides:
eraseSourceFeedback
in class org.eclipse.gef.editpolicies.AbstractEditPolicy
- See Also:
AbstractEditPolicy.eraseSourceFeedback(org.eclipse.gef.Request)
eraseSourceFeedBack
protected void eraseSourceFeedBack(int oldUDistance,
int oldVDistance,
EdgeObjectUV edgeObject)
- Erases source feedback based on the given oldUDistance,
oldVDistance and edge object.
Subclass must reimplement this method
to customize the feedback.
Default implementation reinitialize the
edge object figure with the initial edge object uDistance and vDistance.
- Parameters:
uDistance
- the old uDistance. It is the edge object uDistance hereedgeObject
- an edge object
getCommand
public org.eclipse.gef.commands.Command getCommand(org.eclipse.gef.Request request)
- Specified by:
getCommand
in interface org.eclipse.gef.EditPolicy
- Overrides:
getCommand
in class org.eclipse.gef.editpolicies.AbstractEditPolicy
- See Also:
AbstractEditPolicy.getCommand(org.eclipse.gef.Request)
getMoveEdgeObjectCommand
protected org.eclipse.gef.commands.Command getMoveEdgeObjectCommand(MoveEdgeObjectRequest request)
- Gets the command to move an edge object.
- Parameters:
request
- the move edge object request
- Returns:
- a comand to move an edge object
isEnd
protected abstract boolean isEnd(IEdgeObjectFigure figure)
- Returns
true
if the given edge ovject uv figure is located
at the end of the connection or false
if it is located at
the start.
- Returns:
computeUVDistance
protected int[] computeUVDistance(org.eclipse.draw2d.geometry.Dimension moveDelta,
EdgeObjectUV edgeObject,
org.eclipse.draw2d.geometry.Point mouseLocation)
- Compute a new uDistance and vDistance depending on the move delta and the
edge object figure.
- Parameters:
moveDelta
- the current move deltaedgeObject
- an edge objectmouseLocation
- the mouse location
- Returns:
- an int array containing the uDistance and the vDistance
