isContainedBy method
This predicate is true if this object is an element, perhaps indirectly, of the given panel.
For example, if this GraphObject is inside a Part but is not itself the Part,
obj.isContainedBy(obj.part)
should be true.
@param {GraphObject} panel
@return {boolean} true if this object is contained by the given panel,
or if it is contained by another panel that is contained by the given panel,
to any depth; false if the argument is null or is not a Panel.
Implementation
_i2.bool isContainedBy(_i3.GraphObject panel) => _i4.callMethod(
this,
'isContainedBy',
[panel],
);
