The EzPlug library is meant to help developers write plug-ins fast and efficiently, i.e. focusing on the major aspect of the work ("the main code") and leaving aside tedious aspects such as GUI design for parameter input and threading issues.
In more details:
Using a small set of methods (see tutorial below), EzPlug lets developers create nice-looking plug-ins, without any necessary knowledge in GUI programming. These methods allow to declare a number of parameters of various types (booleans, numbers, enumerations, arrays, etc.), each of which embarks a ready-to-use GUI component that automatically shows up in the interface at run-time. The main execution code runs in a background thread (no more nasty GUI hangs). Other convenience methods allow the developer to support a "stop" button (that automatically appears on the interface if supported), as well as the built-in functionality to save/load parameters to/from an xml file on disk.
More than just words, here is a tutorial code below, which you can directly copy-paste and use to try out most of EzPlug's features.
Happy (at last !) coding !
