Most of these questions were about problems that I had also run into. As a result awhile ago I started to write my own menus to provide myself with more functionality. Anyhow, this code is available via anonymous ftp to bu-it.bu.edu (128.197.2.40). It is in the "sgi" directory. There are two files "Menu.tar" (the menu code) and "Ctedit.tar". Ctedit is a color table editor that uses splines or a frequency/phase method of modifying a color table. The following is a part of the README file from the menus... Some things it does that people on the net have inquired about are.... 1) You can attach a pop up menu to any or all mouse buttons. 2) It has menus that will stay open until closed. This way you can choose more than one item at a time. 3) You can specify the point on the screen that menus will open. 4) A value associated with a menu item is passed to the callback function along with the index of the chosen menu item. Some additional things it does.... 1) It has panels. By a "panel" I mean a menu whose elements are sliders. 2) A means of "ripping out" and "putting in" menu elements. I use this to associate menu elements with one another. For example in my "scientific visualization" code I have a menu of files that have submenus of data elements within the file. A different menu has slots that define the points and colors of a plot/surface/volume /whatever. The user can then "rip out" the data elements and "put in" to one of the slots of the plot menu and thus build a plot. 3) A way of modifing a menu without deallocating and rebuilding the whole thing. -Tim Hall tjh@bu-pub.bu.edu
