Summary
Provides methods for isolating selected subsets of the path stored in a TGPGraphicsPath object.
Description
The TGPGraphicsPathIterator class provides methods for isolating selected subsets of the path stored in a TGPGraphicsPath object. A path consists of one or more figures. You can use a TGPGraphicsPathIterator to isolate one or more of those figures. A path can also have markers that divide the path into sections. You can use a TGPGraphicsPathIterator object to isolate one or more of those sections.
