TRubberbandLayer

Hierarchy

TPersistent

Description

This class implements a rubber band, allowing to move and resize other positioned layers at run-time. The layer paints itself at GDI Overlays stage, using the standard GDI methods.

It is a good idea to keep TRubberbandLayer on top of other layers so that thay don't intercept mouse messages.

Note, that this is a preliminary implementation of rubber banding, there is a lot to be done here to make its behavior more consistent, which will be done in future versions of the library. However, most likely I will keep names and general meaning of most properties and methods.
