sfclipboard
Clipboard object
Syntax
Description
returns the
clipboard
= sfclipboardStateflow.Clipboard
object. Use
the Clipboard
object to copy and paste objects within the same
chart, between charts in the same Simulink® model, or between charts in different models.
Examples
Copy and Paste by Grouping
Group state A
and copy its contents to chart ch
.
When you group a state, box, or graphical function, you can copy and paste all the
objects contained in the grouped object, as well as all the relationships among these
objects. This method is the simplest way of copying and pasting objects
programmatically. If a state is not grouped, copying the state does not copy any of its
contents.
Find the
Stateflow.State
object namedA
in chartch
.sA = find(ch,"-isa","Stateflow.State",Name="A");
Group state
A
and its contents by setting theIsGrouped
property forsA
totrue
. Save the previous setting of this property so you can revert to it later.prevGrouping = sA.IsGrouped; sA.IsGrouped = true;
Change the name of the state to
Copy_of_A
. Save the previous name so you can revert to it later.prevName = sA.Name; newName = "Copy_of_"+prevName; sA.Name = newName;
Access the clipboard object.
cb = sfclipboard;
Copy the grouped state to the clipboard.
copy(cb,sA);
Restore the state properties to their original settings.
sA.IsGrouped = prevGrouping; sA.Name = prevName;
Paste a copy of the objects from the clipboard to the chart.
pasteTo(cb,ch);
Adjust the state properties of the new state.
sNew = find(ch,"-isa","Stateflow.State",Name=newName); sNew.Position = sA.Position + [400 0 0 0]; sNew.IsGrouped = prevGrouping;
Copy and Paste Array of Objects
Copy states A1
and A2
, along with the transition
between them, to a new state in chart ch
. To preserve transition
connections and containment relationships between objects, copy all the connected
objects at once.
Find the
Stateflow.State
object namedA
in chartch
.sA = find(ch,"-isa","Stateflow.State",Name="A");
Add a new state called
B
. To enable pasting of other objects insideB
, convert the new state to a subchart.sB = Stateflow.State(ch); sB.Name = "B"; sB.Position = sA.Position + [400 0 0 0]; sB.IsSubchart = true;
Create an array called
objArray
that contains the states and transitions in stateA
. Use the functionsetdiff
to remove stateA
from the array of objects to copy.objArrayS = find(sA,"-isa","Stateflow.State"); objArrayS = setdiff(objArrayS,sA); objArrayT = find(sA,"-isa","Stateflow.Transition"); objArray = [objArrayS objArrayT];
Access the clipboard object.
cb = sfclipboard;
Copy the objects in
objArray
and paste them in subchartB
.copy(cb,objArray); pasteTo(cb,sB);
Revert
B
to a state.sB.IsSubchart = false; sB.IsGrouped = false;
Reposition the states and transitions in
B
.newStates = find(sB,"-isa","Stateflow.State"); newStates = setdiff(newStates,sB); newTransitions = find(sB,"-isa","Stateflow.Transition"); newOClocks = get(newTransitions,{"SourceOClock","DestinationOClock"}); for i = 1:numel(newStates) newStates(i).Position = newStates(i).Position + [25 35 0 0]; end set(newTransitions,{"SourceOClock","DestinationOClock"},newOClocks);
