XView I

XView is a toolkit of C objects and functions which allow the construction of window-based tools. Tools written using XView comply to the OPEN LOOK interface standard for user interface look-and-feel. The tools introduced in Chapter 1 were written using XView and C. This chapter will consider how tools are written, starting with the tool layout, then handling the interaction between user and tool and finally looking at the internal non-window functions of the tool. The example given will look mainly at the Panel subwindow package. Chapter 4 will look at the Canvas package.
