Description

Pd comes with a quite limited set of GUI objects. Some additional GUI externals exist (e.g. knob, iemgui, ...), but a more complete and easy to use library should be written to build fancy user interfaces. All GUI objects in pd are written with the cross-platform Tcl/Tk toolkit.

The inspiration for new objects can come from similar programs (e.g. "Max/MSP") and should be discussed with the mentors and at the mailing list. Furthermore all objects should be graph-on-parrent capable and cross-platform.

Resources to start:

• http://iem.kug.ac.at/pd/externals-HOWTO : a tutorial on how to write C externals for pure data

• http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/externals/tkwidgets/ : the framework for a library based on Tcl/Tk's built-in widgets

• http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/externals/iem/iemgui/ : the iemgui externals, the code can be used to study how to write GUI externals for pd

• http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/pd/src/ : files starting with *g_* are pds original GUI objects

• http://www.tcl.tk/doc/ : documentation/tutorial for Tcl/Tk

Required Skills

• C programming

• willing to dive into Tcl/Tk
