I am new to the X programming(environment). I am programming using Xlib functions/features offered by X11 (Xlibraries). I am not using any sort of widgets or toolkits for my application. I succesfully compiled and linked a program (program is a simple one, i.e to write my name in a rectangle). The executable program is upto date (i.e without any errors). When I execute the program, I can succesfully connect to the X server. But nothing will be displayed on the terminal (in the window).the control returns to the unix shell ( in the default window, i.e the window started by 'xinit'). For executing any program, I am not sure whether 'uwm','xterm' should be running at background mode or not. But even if they are running in background and if I execute my program, the response is same as mentioned. For any thing to be displayed, the corresponding window should be mapped(even the parents). But before mapping a window, standard properties are to be set using XSetStandardProperties(.......) function (of Xlib). This function has Argc & Argv as two of the arguments to be passed/specified. These arguments are to be passed while executing the program (i.e command line arguments). But I do not know the arguments to be specified, the syntax /format of the arguments. I am not able to conceive this concept from the book (Xlib programming manual, by Adrian Nye, O'Reilly Associates, volume 1) The program I have written is almost similar to the one given in the manual (Basicwin program, page 77). Please send your replies/answers/suggestions to the e-mail address given below. I thank you in advance for the help. - Satish .

It sounds as though your program will open a new window on the screen and write your name in that new window. If no new window appears, or if a new window appears but nothing is written in it, then there is some other problem with your program. > But before mapping a window, standard properties > are to be set using XSetStandardProperties(.......) function (of Xlib). > This function has Argc & Argv as two of the arguments to be passed/specified. > These arguments are to be passed while executing the program (i.e command > line arguments).

Just pass in argv and argc as your program received them from the command line. It will be used to set the WM_COMMAND property. The window manager will communicate this information to the session manager, which uses this and other information to re-start your programs at the point where you last stopped working, for example, to allow to pick up work where you last left off, between login sessions. Your X software may not have a session manager. Donna Converse converse@expo.lcs.mit.edu

For executing any program, This sounds like your program doesn't flush the output buffer, or doesn't wait for any events (which automagicly flushes the output buffer). A lot of people make this mastake (even after reading it in a X book). >...But before mapping a window, standard properties >are to be set using XSetStandardProperties(.......) function (of Xlib). >line arguments).
