7:30 PM Presentation Rapid Motif Development using Motif Tools (libXmt) by Scott Nesler, Daugherty Systems


Rapid Motif Development using Motif Tools (libXmt) by Scott Nesler, Daugherty Systems

Motif Tools (Xmt) is a software library that makes developing Motif user interfaces much easier. Xmt consists of several new widgets and many convenience functions that aid in user interface development. Motif tools is a much friendlier environment to build GUI's than straight Motif. One of the prime advantages of Xmt is that it allows most of the user interface to be specified in a resource file. This resource file can be used to do rapid prototypes without having to write a line of C code. In addition, Xmt provides a mechanism to automatically transfer data between dialog boxes and application code, a feature that makes interfacing the code and user interface very modular and much easier than traditional methods. Scott will demonstrate Motif tools, some of the widgets and how to use them, strategies for simplifying Motif development, and where to get Motif tools and documentation.

Scott Nesler is a consultant for Daugherty Systems. Scott has spent most of his career doing GUI development on UNIX systems, first using Xlib directly, then Motif, and for the last 4 years Motif tools. He has built GUIs for both scientific and business applications and has helped other programmers to learn how to develop GUIs also.


X Resource Files by Stan Balwin

The tutorial will be by SLUUG member Stan Balwin. Stan will discuss X resource files: How to find them. How to specify resources.
