See reader questions & answers on this topic! - Help others by sharing your knowledge The 'Screen' is an Xlib structure which includes the information about one of the monitors or virtual monitors which a single X display supports. A server can support several independent screens. They are numbered unix:0.0, unix:0.1, unix:0.2, etc; the 'screen' or 'screen_number' is the second digit -- the 0, 1, 2 which can be thought of as an index into the array of available Screens on this particular Display connection. The macros which you can use to obtain information about the particular Screen on which your application is running typically have two forms -- one which takes a Screen and one with takes both the Display and the screen_number. In Xt-based programs, you typically use XtScreen(widget) to determine the Screen on which your application is running, if it uses a single screen. (Part of the confusion may arise from the fact that some of the macros which return characteristics of the Screen have "Display" in the names -- DisplayWidth, DisplayHeight, etc.) User Contributions:Top Document: comp.windows.x Frequently Asked Questions (FAQ) 7/7 Previous Document: 172) Why doesn't anything appear when I run this simple program?
